The Company sells to consumers, small and mid-sized businesses and education, enterprise and government customers. Basis of Presentation and Preparation The accompanying condensed consolidated financial statements include the accounts of the Company. Intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The preparation of these condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Certain prior period amounts in the condensed consolidated financial statements have been reclassified to conform to the current period’s presentation. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended September 24, 2016 (the “ 2016 Form 10-K”). The Company’s fiscal year is the 52 or 53-week period that ends on the last Saturday of September. The Company’s fiscal year 2017 will include 53 weeks and ends on September 30, 2017 and its fiscal year 2016 included 52 weeks and ended on September 24, 2016 . A 14th week was included in the first quarter of 2017, as is done every five or six years, to realign fiscal quarters with calendar quarters. Unless otherwise stated, references to particular years, quarters, months and periods refer to the Company’s fiscal years ended in September and the associated quarters, months and periods of those fiscal years. Earnings Per Share Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased by employees under the Company’s employee stock purchase plan, unvested restricted stock and unvested restricted stock units (“RSUs”). The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. The following table shows the computation of basic and diluted earnings per share for the three- and nine-month periods ended July 1, 2017 and June 25, 2016 (net income in millions and shares in thousands): Three Months Ended Nine Months Ended July 1, June 25, July 1, June 25, Numerator: Net income $ 8,717 $ 7,796 $ 37,637 $ 36,673 Denominator: Weighted-average shares outstanding 5,195,088 5,443,058 5,239,847 5,505,456 Effect of dilutive securities 38,411 29,723 34,547 30,475 Weighted-average diluted shares 5,233,499 5,472,781 5,274,394 5,535,931 Basic earnings per share $ 1.68 $ 1.43 $ 7.18 $ 6.66 Diluted earnings per share $ 1.67 $ 1.42 $ 7.14 $ 6.62 Potentially dilutive securities whose effect would have been antidilutive are excluded from the computation of diluted earnings per share.

(2) Level 2 fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and duration management. The maturities of the Company’s long-term marketable securities generally range from one to five years . The Company considers the declines in market value of its marketable securities investment portfolio to be temporary in nature. The Company typically invests in highly-rated securities, and its investment policy generally limits the amount of credit exposure to any one issuer. The policy generally requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss. Fair values were determined for each individual security in the investment portfolio. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. As of July 1, 2017 , the Company does not consider any of its investments to be other-than-temporarily impaired. Derivative Financial Instruments The Company may use derivatives to partially offset its business exposure to foreign currency and interest rate risk on expected future cash flows, on net investments in certain foreign subsidiaries and on certain existing assets and liabilities. However, the Company may choose not to hedge certain exposures for a variety of reasons including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange or interest rates. To help protect gross margins from fluctuations in foreign currency exchange rates, certain of the Company’s subsidiaries whose functional currency is the U.S. dollar may hedge a portion of forecasted foreign currency revenue, and subsidiaries whose functional currency is not the U.S. dollar and who sell in local currencies may hedge a portion of forecasted inventory purchases not denominated in the subsidiaries’ functional currencies. The Company may enter into forward contracts, option contracts or other instruments to manage this risk and may designate these instruments as cash flow hedges. The Company typically hedges portions of its forecasted foreign currency exposure associated with revenue and inventory purchases, typically for up to 12 months . To help protect the net investment in a foreign operation from adverse changes in foreign currency exchange rates, the Company may enter into foreign currency forward and option contracts to offset the changes in the carrying amounts of these investments due to fluctuations in foreign currency exchange rates. In addition, the Company may use non-derivative financial instruments, such as its foreign currency-denominated debt, as economic hedges of its net investments in certain foreign subsidiaries. In both of these cases, the Company designates these instruments as net investment hedges. The Company may also enter into non-designated foreign currency contracts to partially offset the foreign currency exchange gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. The Company may enter into interest rate swaps, options, or other instruments to manage interest rate risk. These instruments may offset a portion of changes in income or expense, or changes in fair value of the Company’s term debt or investments. The Company designates these instruments as either cash flow or fair value hedges. The Company’s hedged interest rate transactions as of July 1, 2017 are expected to be recognized within 10 years . Cash Flow Hedges The effective portions of cash flow hedges are recorded in accumulated other comprehensive income (“AOCI”) until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges of foreign currency revenue are recognized as a component of net sales in the same period as the related revenue is recognized, and deferred gains and losses related to cash flow hedges of inventory purchases are recognized as a component of cost of sales in the same period as the related costs are recognized. Deferred gains and losses associated with cash flow hedges of interest income or expense are recognized in other income/(expense), net in the same period as the related income or expense is recognized. The ineffective portions and amounts excluded from the effectiveness testing of cash flow hedges are recognized in other income/(expense), net. Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Deferred gains and losses in AOCI associated with such derivative instruments are reclassified immediately into other income/(expense), net. Any subsequent changes in fair value of such derivative instruments are reflected in other income/(expense), net unless they are re-designated as hedges of other transactions. Net Investment Hedges The effective portions of net investment hedges are recorded in other comprehensive income (“OCI”) as a part of the cumulative translation adjustment. The ineffective portions and amounts excluded from the effectiveness testing of net investment hedges are recognized in other income/(expense), net. Fair Value Hedges Gains and losses related to changes in fair value hedges are recognized in earnings along with a corresponding loss or gain related to the change in value of the underlying hedged item. Non-Designated Derivatives Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in the financial statement line item to which the derivative relates. As a result, during the three- and nine -month periods ended July 1, 2017 , respectively, the Company recognized a loss of $77 million and a gain of $129 million in net sales, gains of $12 million and $91 million in cost of sales and gains of $49 million and $481 million in other income/(expense), net. The Company records all derivatives in the Condensed Consolidated Balance Sheets at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation.

The credit risk amounts represent the Company’s gross exposure to potential accounting loss on derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of the contract, based on then-current currency or interest rates at each respective date. The Company’s exposure to credit loss and market risk will vary over time as currency and interest rates change. Although the table above reflects the notional and credit risk amounts of the Company’s derivative instruments, it does not reflect the gains or losses associated with the exposures and transactions that the instruments are intended to hedge. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments. The Company generally enters into master netting arrangements, which are designed to reduce credit risk by permitting net settlement of transactions with the same counterparty. To further limit credit risk, the Company generally enters into collateral security arrangements that provide for collateral to be received or posted when the net fair value of certain financial instruments fluctuates from contractually established thresholds. The Company presents its derivative assets and derivative liabilities at their gross fair values in its Condensed Consolidated Balance Sheets. As of July 1, 2017 , the net cash collateral posted by the Company related to derivative instruments under its collateral security arrangements was $162 million , which was recorded as other current assets in the Condensed Consolidated Balance Sheet. As of September 24, 2016 , the net cash collateral received by the Company related to derivative instruments under its collateral security arrangements was $163 million , which was recorded as accrued expenses in the Condensed Consolidated Balance Sheet. Under master netting arrangements with the respective counterparties to the Company’s derivative contracts, the Company is allowed to net settle transactions with a single net amount payable by one party to the other. As of July 1, 2017 and September 24, 2016 , the potential effects of these rights of set-off associated with the Company’s derivative contracts, including the effects of collateral, would be a reduction to both derivative assets and derivative liabilities of $1.3 billion and $1.5 billion , respectively, resulting in a net derivative liability of $326 million and a net derivative asset of $160 million , respectively. Accounts Receivable Trade Receivables The Company has considerable trade receivables outstanding with its third-party cellular network carriers, wholesalers, retailers, value-added resellers, small and mid-sized businesses and education, enterprise and government customers. The Company generally does not require collateral from its customers; however, the Company will require collateral in certain instances to limit credit risk. In addition, when possible, the Company attempts to limit credit risk on trade receivables with credit insurance for certain customers or by requiring third-party financing, loans or leases to support credit exposure. These credit-financing arrangements are directly between the third-party financing company and the end customer. As such, the Company generally does not assume any recourse or credit risk sharing related to any of these arrangements. The Company had no customers that individually represented 10% or more of total trade receivables as of July 1, 2017 . As of September 24, 2016 , the Company had one customer that represented 10% or more of total trade receivables, which accounted for 10% . The Company’s cellular network carriers accounted for 46% and 63% of total trade receivables as of July 1, 2017 and September 24, 2016 , respectively. Vendor Non-Trade Receivables The Company has non-trade receivables from certain of its manufacturing vendors resulting from the sale of components to these vendors who manufacture sub-assemblies or assemble final products for the Company. The Company purchases these components directly from suppliers. As of July 1, 2017 , the Company had three vendors that individually represented 10% or more of total vendor non-trade receivables, which accounted for 39% , 19% and 16% . As of September 24, 2016 , the Company had two vendors that individually represented 10% or more of total vendor non-trade receivables, which accounted for 47% and 21% .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As of July 1, 2017 , the Company recorded gross unrecognized tax benefits of $8.6 billion , of which $2.6 billion , if recognized, would affect the Company’s effective tax rate. As of September 24, 2016 , the total amount of gross unrecognized tax benefits was $7.7 billion , of which $2.8 billion , if recognized, would have affected the Company’s effective tax rate. The Company’s total gross unrecognized tax benefits are classified as other non-current liabilities in the Condensed Consolidated Balance Sheets. The Company had $1.3 billion and $1.0 billion of gross interest and penalties accrued as of July 1, 2017 and September 24, 2016 , respectively, which are classified as other non-current liabilities in the Condensed Consolidated Balance Sheets. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with its expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Although timing of the resolution and/or closure of audits is not certain, the Company believes it is reasonably possible that its gross unrecognized tax benefits could decrease (whether by payment, release or a combination of both) in the next 12 months by as much as $700 million . On August 30, 2016, the European Commission announced its decision that Ireland granted state aid to the Company by providing tax opinions in 1991 and 2007 concerning the tax allocation of profits of the Irish branches of two subsidiaries of the Company (the “State Aid Decision”). The State Aid Decision orders Ireland to calculate and recover additional taxes from the Company for the period June 2003 through December 2014. Irish legislative changes, effective as of January 2015, eliminated the application of the tax opinions from that date forward. The Company believes the State Aid Decision to be without merit and appealed to the General Court of the Court of Justice of the European Union. Ireland has also appealed the State Aid Decision. While the European Commission announced a recovery amount of up to €13 billion , plus interest, the actual amount of additional taxes subject to recovery is to be calculated by Ireland in accordance with the European Commission’s guidance. Once the recovery amount is computed by Ireland, the Company anticipates funding it, including interest, out of foreign cash into escrow, where it will remain pending conclusion of all appeals. The Company believes that any incremental Irish corporate income taxes potentially due related to the State Aid Decision would be creditable against U.S. taxes.

The Company also hedged its entire third quarter 2017 issuance of €2.5 billion of euro-denominated notes by entering into foreign currency swaps to effectively convert these notes to U.S. dollar-denominated notes. To manage interest rate risk on certain of its fixed-rate notes issued during the second quarter of 2017 and maturing in 2020, 2022, 2024 and 2027, the Company entered into interest rate swaps with an aggregate notional amount of $6.5 billion , which effectively converted the fixed interest rates on these notes to floating interest rates. A portion of the Company’s Japanese yen-denominated notes is designated as a hedge of the foreign currency exposure of the Company’s net investment in a foreign operation. The foreign currency transaction gain or loss on the Japanese yen-denominated debt designated as a hedge is recorded in OCI as a part of the cumulative translation adjustment. As of July 1, 2017 and September 24, 2016 , the carrying value of the debt designated as a net investment hedge was $1.5 billion and $1.9 billion , respectively. For further discussion regarding the Company’s use of derivative instruments see the Derivative Financial Instruments section of Note 2, “Financial Instruments.” The effective interest rates for the Notes include the interest on the Notes, amortization of the discount or premium and, if applicable, adjustments related to hedging. The Company recognized $574 million and $1.6 billion of interest expense on its term debt for the three- and nine-month periods ended July 1, 2017 , respectively. The Company recognized $393 million and $975 million of interest expense on its term debt for the three- and nine-month periods ended June 25, 2016 , respectively. As of July 1, 2017 and September 24, 2016 , the fair value of the Company’s Notes, based on Level 2 inputs, was $98.3 billion and $81.7 billion , respectively.

Share Repurchase Program In May 2017, the Company’s Board of Directors increased the share repurchase authorization from $175 billion to $210 billion of the Company’s common stock, of which $158 billion had been utilized as of July 1, 2017 . The Company’s share repurchase program does not obligate it to acquire any specific number of shares. Under the program, shares may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Company has entered, and in the future may enter, into accelerated share repurchase arrangements (“ASRs”) with financial institutions. In exchange for up-front payments, the financial institutions deliver shares of the Company’s common stock during the purchase periods of each ASR. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, is determined at the end of the applicable purchase period of each ASR based on the volume-weighted average price of the Company’s common stock during that period. The shares received are retired in the periods they are delivered, and the up-front payments are accounted for as a reduction to shareholders’ equity in the Company’s Condensed Consolidated Balance Sheets in the periods the payments are made. The Company reflects the ASRs as a repurchase of common stock in the period delivered for purposes of calculating earnings per share and as forward contracts indexed to its own common stock. The ASRs met all of the applicable criteria for equity classification, and therefore were not accounted for as derivative instruments. The following table shows the Company’s ASR activity and related information during the nine months ended July 1, 2017 and the year ended September 24, 2016 : Purchase Period End Date Number of Shares (in thousands) Average Repurchase Price Per Share ASR Amount (in millions) May 2017 ASR August 2017 15,598 (1) (1) $ 3,000 February 2017 ASR May 2017 20,949 (2) $ 143.20 $ 3,000 November 2016 ASR February 2017 51,157 $ 117.29 $ 6,000 August 2016 ASR November 2016 26,850 $ 111.73 $ 3,000 May 2016 ASR August 2016 60,452 $ 99.25 $ 6,000 November 2015 ASR April 2016 29,122 $ 103.02 $ 3,000 (1) “Number of Shares” represents those shares delivered at the beginning of the purchase period and does not represent the final number of shares to be delivered under the ASR. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, will be determined at the end of the purchase period based on the volume-weighted average price of the Company’s common stock during that period. The May 2017 ASR purchase period will end in August 2017 . (2) Includes 17.5 million shares delivered and retired at the beginning of the purchase period, which began in the second quarter of 2017 and 3.4 million shares delivered and retired at the end of the purchase period, which concluded in the third quarter of 2017.

Benefit Plans	Benefit Plans Stock Plans The Company had 328.1 million shares reserved for future issuance under its stock plans as of July 1, 2017 . RSUs granted generally vest over four years , based on continued employment, and are settled upon vesting in shares of the Company’s common stock on a one -for-one basis. Each share issued with respect to RSUs granted under the Company’s stock plans reduces the number of shares available for grant under the plan by two shares. RSUs canceled and shares withheld to satisfy tax withholding obligations increase the number of shares available for grant under the plans utilizing a factor of two times the number of RSUs canceled or shares withheld. Rule 10b5-1 Trading Plans During the three months ended July 1, 2017 , Section 16 officers Angela Ahrendts, Timothy D. Cook, Luca Maestri, Daniel Riccio and Philip Schiller had equity trading plans in place in accordance with Rule 10b5-1(c)(1) under the Exchange Act. An equity trading plan is a written document that pre-establishes the amounts, prices and dates (or formula for determining the amounts, prices and dates) of future purchases or sales of the Company’s stock, including shares acquired pursuant to the Company’s employee and director equity plans.

Commitments and Contingencies	Commitments and Contingencies Accrued Warranty and Indemnification The following table shows changes in the Company’s accrued warranties and related costs for the three- and nine-month periods ended July 1, 2017 and June 25, 2016 (in millions): Three Months Ended Nine Months Ended July 1, June 25, July 1, June 25, Beginning accrued warranty and related costs $ 4,735 $ 4,985 $ 3,702 $ 4,780 Cost of warranty claims (932 ) (1,110 ) (3,300 ) (3,507 ) Accruals for product warranty 496 380 3,897 2,982 Ending accrued warranty and related costs $ 4,299 $ 4,255 $ 4,299 $ 4,255 Agreements entered into by the Company sometimes include indemnification provisions which may subject the Company to costs and damages in the event of a claim against an indemnified third party. In the opinion of management, there was not at least a reasonable possibility the Company may have incurred a material loss, or a material loss in excess of a recorded accrual, with respect to indemnification of third parties. The Company offers an iPhone Upgrade Program, which is available to customers who purchase a qualifying iPhone in the U.S., the U.K. and mainland China. The iPhone Upgrade Program provides customers the right to trade in that iPhone for a specified amount when purchasing a new iPhone, provided certain conditions are met. The Company accounts for the trade-in right as a guarantee liability and recognizes arrangement revenue net of the fair value of such right with subsequent changes to the guarantee liability recognized within revenue. The Company has entered into indemnification agreements with its directors and executive officers. Under these agreements, the Company has agreed to indemnify such individuals to the fullest extent permitted by law against liabilities that arise by reason of their status as directors or officers of the Company and to advance expenses incurred by such individuals in connection with related legal proceedings. It is not possible to determine the maximum potential amount of payments the Company could be required to make under these agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each claim. While the Company maintains directors and officers liability insurance coverage, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise. Concentrations in the Available Sources of Supply of Materials and Product Although most components essential to the Company’s business are generally available from multiple sources, a number of components are currently obtained from single or limited sources. In addition, the Company competes for various components with other participants in the markets for mobile communication and media devices and personal computers. Therefore, many components used by the Company, including those that are available from multiple sources, are at times subject to industry-wide shortage and significant pricing fluctuations that could materially adversely affect the Company’s financial condition and operating results. The Company uses some custom components that are not commonly used by its competitors, and new products introduced by the Company often utilize custom components available from only one source. When a component or product uses new technologies, initial capacity constraints may exist until the suppliers’ yields have matured or manufacturing capacity has increased. If the Company’s supply of components for a new or existing product were delayed or constrained, or if an outsourcing partner delayed shipments of completed products to the Company, the Company’s financial condition and operating results could be materially adversely affected. The Company’s business and financial performance could also be materially adversely affected depending on the time required to obtain sufficient quantities from the original source, or to identify and obtain sufficient quantities from an alternative source. Continued availability of these components at acceptable prices, or at all, may be affected if those suppliers decide to concentrate on the production of common components instead of components customized to meet the Company’s requirements. The Company has entered into agreements for the supply of many components; however, there can be no guarantee that the Company will be able to extend or renew these agreements on similar terms, or at all. Therefore, the Company remains subject to significant risks of supply shortages and price increases that could materially adversely affect its financial condition and operating results. Substantially all of the Company’s hardware products are manufactured by outsourcing partners that are located primarily in Asia. A significant concentration of this manufacturing is currently performed by a small number of outsourcing partners, often in single locations. Certain of these outsourcing partners are the sole-sourced suppliers of components and manufacturers for many of the Company’s products. Although the Company works closely with its outsourcing partners on manufacturing schedules, the Company’s operating results could be adversely affected if its outsourcing partners were unable to meet their production commitments. The Company’s manufacturing purchase obligations typically cover its requirements for periods up to 150 days . Other Off-Balance Sheet Commitments Operating Leases The Company leases various equipment and facilities, including retail space, under noncancelable operating lease arrangements. The Company does not currently utilize any other off-balance sheet financing arrangements. As of July 1, 2017 , the Company’s total future minimum lease payments under noncancelable operating leases were $8.5 billion . The Company’s retail store and other facility leases are typically for terms not exceeding 10 years and generally contain multi-year renewal options. Contingencies The Company is subject to various legal proceedings and claims that have arisen in the ordinary course of business and that have not been fully adjudicated, as further discussed in Part II, Item 1 of this Form 10-Q under the heading “Legal Proceedings” and in Part II, Item 1A of this Form 10-Q under the heading “Risk Factors.” In the opinion of management, there was not at least a reasonable possibility the Company may have incurred a material loss, or a material loss in excess of a recorded accrual, with respect to loss contingencies for asserted legal and other claims. However, the outcome of litigation is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period for amounts in excess of management’s expectations, the Company’s consolidated financial statements for that reporting period could be materially adversely affected. Apple Inc. v. Samsung Electronics Co., Ltd., et al. On August 24, 2012, a jury returned a verdict awarding the Company $1.05 billion in its lawsuit against Samsung Electronics Co., Ltd. and affiliated parties in the United States District Court, Northern District of California, San Jose Division. On March 6, 2014, the District Court entered final judgment in favor of the Company in the amount of approximately $930 million . On May 18, 2015, the U.S. Court of Appeals for the Federal Circuit affirmed in part, and reversed in part, the decision of the District Court. As a result, the Court of Appeals ordered entry of final judgment on damages in the amount of approximately $548 million , with the District Court to determine supplemental damages and interest, as well as damages owed for products subject to the reversal in part. Samsung paid $548 million to the Company in December 2015, which was included in net sales in the Condensed Consolidated Statement of Operations. On December 6, 2016, the U.S. Supreme Court remanded the case to the U.S. Court of Appeals for the Federal Circuit for further proceedings related to the $548 million in damages. On February 7, 2017, the U.S. Court of Appeals for the Federal Circuit remanded the case to the District Court to determine what additional proceedings, if any, are needed. Because the case remains subject to further proceedings, the Company has not recognized any further amounts in its results of operations.

Segment Reporting [Abstract]
Segment Information and Geographic Data	Segment Information and Geographic Data The Company reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable operating segments. The Company manages its business primarily on a geographic basis. The Company’s reportable operating segments consist of the Americas, Europe, Greater China, Japan and Rest of Asia Pacific. The Americas segment includes both North and South America. The Europe segment includes European countries, as well as India, the Middle East and Africa. The Greater China segment includes China, Hong Kong and Taiwan. The Rest of Asia Pacific segment includes Australia and those Asian countries not included in the Company’s other reportable operating segments. Although the reportable operating segments provide similar hardware and software products and similar services, each one is managed separately to better align with the location of the Company’s customers and distribution partners and the unique market dynamics of each geographic region. The accounting policies of the various segments are the same as those described in Note 1, “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in Part II, Item 8 of the 2016 Form 10-K. The Company evaluates the performance of its reportable operating segments based on net sales and operating income. Net sales for geographic segments are generally based on the location of customers and sales through the Company’s retail stores located in those geographic locations. Operating income for each segment includes net sales to third parties, related cost of sales and operating expenses directly attributable to the segment. Advertising expenses are generally included in the geographic segment in which the expenditures are incurred. Operating income for each segment excludes other income and expense and certain expenses managed outside the reportable operating segments. Costs excluded from segment operating income include various corporate expenses such as research and development, corporate marketing expenses, certain share-based compensation expenses, income taxes, various nonrecurring charges and other separately managed general and administrative costs. The Company does not include intercompany transfers between segments for management reporting purposes. The following table shows information by reportable operating segment for the three- and nine-month periods ended July 1, 2017 and June 25, 2016 (in millions): Three Months Ended Nine Months Ended July 1, June 25, July 1, June 25, Americas: Net sales $ 20,376 $ 17,963 $ 73,501 $ 66,384 Operating income $ 6,420 $ 5,453 $ 23,582 $ 21,587 Europe: Net sales $ 10,675 $ 9,643 $ 41,929 $ 39,110 Operating income $ 2,984 $ 2,666 $ 12,571 $ 12,047 Greater China: Net sales $ 8,004 $ 8,848 $ 34,963 $ 39,707 Operating income $ 3,002 $ 3,415 $ 13,402 $ 15,809 Japan: Net sales $ 3,624 $ 3,529 $ 13,875 $ 12,604 Operating income $ 1,624 $ 1,435 $ 6,334 $ 5,605 Rest of Asia Pacific: Net sales $ 2,729 $ 2,375 $ 12,387 $ 10,982 Operating income $ 892 $ 753 $ 4,430 $ 3,880 A reconciliation of the Company’s segment operating income to the Condensed Consolidated Statements of Operations for the three- and nine-month periods ended July 1, 2017 and June 25, 2016 is as follows (in millions): Three Months Ended Nine Months Ended July 1, June 25, July 1, June 25, Segment operating income $ 14,922 $ 13,722 $ 60,319 $ 58,928 Research and development expense (2,937 ) (2,560 ) (8,584 ) (7,475 ) Other corporate expenses, net (1,217 ) (1,057 ) (3,511 ) (3,190 ) Total operating income $ 10,768 $ 10,105 $ 48,224 $ 48,263

Summary of Significant Accounting Policies (Policies)	Jul. 01, 2017
Accounting Policies [Abstract]
Basis of Presentation and Preparation	Basis of Presentation and Preparation The accompanying condensed consolidated financial statements include the accounts of the Company. Intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The preparation of these condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Certain prior period amounts in the condensed consolidated financial statements have been reclassified to conform to the current period’s presentation. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended September 24, 2016 (the “ 2016 Form 10-K”).
Fiscal Period	The Company’s fiscal year is the 52 or 53-week period that ends on the last Saturday of September. The Company’s fiscal year 2017 will include 53 weeks and ends on September 30, 2017 and its fiscal year 2016 included 52 weeks and ended on September 24, 2016 . A 14th week was included in the first quarter of 2017, as is done every five or six years, to realign fiscal quarters with calendar quarters. Unless otherwise stated, references to particular years, quarters, months and periods refer to the Company’s fiscal years ended in September and the associated quarters, months and periods of those fiscal years.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased by employees under the Company’s employee stock purchase plan, unvested restricted stock and unvested restricted stock units (“RSUs”). The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. Potentially dilutive securities whose effect would have been antidilutive are excluded from the computation of diluted earnings per share.
Fair Value Measurements	Level 1 fair value estimates are based on quoted prices in active markets for identical assets or liabilities. Level 2 fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Derivative Financial Instruments	Derivative Financial Instruments The Company may use derivatives to partially offset its business exposure to foreign currency and interest rate risk on expected future cash flows, on net investments in certain foreign subsidiaries and on certain existing assets and liabilities. However, the Company may choose not to hedge certain exposures for a variety of reasons including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange or interest rates. To help protect gross margins from fluctuations in foreign currency exchange rates, certain of the Company’s subsidiaries whose functional currency is the U.S. dollar may hedge a portion of forecasted foreign currency revenue, and subsidiaries whose functional currency is not the U.S. dollar and who sell in local currencies may hedge a portion of forecasted inventory purchases not denominated in the subsidiaries’ functional currencies. The Company may enter into forward contracts, option contracts or other instruments to manage this risk and may designate these instruments as cash flow hedges. The Company typically hedges portions of its forecasted foreign currency exposure associated with revenue and inventory purchases, typically for up to 12 months . To help protect the net investment in a foreign operation from adverse changes in foreign currency exchange rates, the Company may enter into foreign currency forward and option contracts to offset the changes in the carrying amounts of these investments due to fluctuations in foreign currency exchange rates. In addition, the Company may use non-derivative financial instruments, such as its foreign currency-denominated debt, as economic hedges of its net investments in certain foreign subsidiaries. In both of these cases, the Company designates these instruments as net investment hedges. The Company may also enter into non-designated foreign currency contracts to partially offset the foreign currency exchange gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. The Company may enter into interest rate swaps, options, or other instruments to manage interest rate risk. These instruments may offset a portion of changes in income or expense, or changes in fair value of the Company’s term debt or investments. The Company designates these instruments as either cash flow or fair value hedges. The Company’s hedged interest rate transactions as of July 1, 2017 are expected to be recognized within 10 years . Cash Flow Hedges The effective portions of cash flow hedges are recorded in accumulated other comprehensive income (“AOCI”) until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges of foreign currency revenue are recognized as a component of net sales in the same period as the related revenue is recognized, and deferred gains and losses related to cash flow hedges of inventory purchases are recognized as a component of cost of sales in the same period as the related costs are recognized. Deferred gains and losses associated with cash flow hedges of interest income or expense are recognized in other income/(expense), net in the same period as the related income or expense is recognized. The ineffective portions and amounts excluded from the effectiveness testing of cash flow hedges are recognized in other income/(expense), net. Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Deferred gains and losses in AOCI associated with such derivative instruments are reclassified immediately into other income/(expense), net. Any subsequent changes in fair value of such derivative instruments are reflected in other income/(expense), net unless they are re-designated as hedges of other transactions. Net Investment Hedges The effective portions of net investment hedges are recorded in other comprehensive income (“OCI”) as a part of the cumulative translation adjustment. The ineffective portions and amounts excluded from the effectiveness testing of net investment hedges are recognized in other income/(expense), net. Fair Value Hedges Gains and losses related to changes in fair value hedges are recognized in earnings along with a corresponding loss or gain related to the change in value of the underlying hedged item. Non-Designated Derivatives Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in the financial statement line item to which the derivative relates. The Company records all derivatives in the Condensed Consolidated Balance Sheets at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation.
Segment Reporting	The Company reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable operating segments. The Company manages its business primarily on a geographic basis. The Company’s reportable operating segments consist of the Americas, Europe, Greater China, Japan and Rest of Asia Pacific. The Americas segment includes both North and South America. The Europe segment includes European countries, as well as India, the Middle East and Africa. The Greater China segment includes China, Hong Kong and Taiwan. The Rest of Asia Pacific segment includes Australia and those Asian countries not included in the Company’s other reportable operating segments. Although the reportable operating segments provide similar hardware and software products and similar services, each one is managed separately to better align with the location of the Company’s customers and distribution partners and the unique market dynamics of each geographic region. The accounting policies of the various segments are the same as those described in Note 1, “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in Part II, Item 8 of the 2016 Form 10-K. The Company evaluates the performance of its reportable operating segments based on net sales and operating income. Net sales for geographic segments are generally based on the location of customers and sales through the Company’s retail stores located in those geographic locations. Operating income for each segment includes net sales to third parties, related cost of sales and operating expenses directly attributable to the segment. Advertising expenses are generally included in the geographic segment in which the expenditures are incurred. Operating income for each segment excludes other income and expense and certain expenses managed outside the reportable operating segments. Costs excluded from segment operating income include various corporate expenses such as research and development, corporate marketing expenses, certain share-based compensation expenses, income taxes, various nonrecurring charges and other separately managed general and administrative costs. The Company does not include intercompany transfers between segments for management reporting purposes.
