Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES Unaudited Interim Financial Information We have prepared the accompanying consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. These consolidated financial statements are unaudited and, in our opinion, include all adjustments, consisting of normal recurring adjustments and accruals necessary for a fair presentation of our consolidated cash flows, operating results, and balance sheets for the periods presented. Operating results for the periods presented are not necessarily indicative of the results that may be expected for 2020 due to seasonal and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted in accordance with the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes in Item 8 of Part II, “Financial Statements and Supplementary Data,” of our 2019 Annual Report on Form 10-K. Principles of Consolidation The consolidated financial statements include the accounts of Amazon.com, Inc. and its consolidated entities (collectively, the “Company”), consisting of its wholly-owned subsidiaries and those entities in which we have a variable interest and of which we are the primary beneficiary, including certain entities in India and certain entities that support our seller lending financing activities. Intercompany balances and transactions between consolidated entities are eliminated. Use of Estimates The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in the consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, income taxes, useful lives of equipment, commitments and contingencies, valuation of acquired intangibles and goodwill, stock-based compensation forfeiture rates, vendor funding, inventory valuation, collectability of receivables, and impairment of investments. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, these estimates are becoming more challenging, and actual results could differ materially from those estimates. We review the useful lives of equipment on an ongoing basis, and effective January 1, 2020 we changed our estimate of the useful life for our servers from three to four years . The longer useful life is due to continuous improvements in our hardware, software, and data center designs. The effect of this change in estimate for Q1 2020 , based on servers that were included in “Property and equipment, net” as of December 31, 2019 and those acquired during the quarter ended March 31, 2020, was a reduction in depreciation and amortization expense of $786 million and an increase in net income of $602 million , or $1.21 per basic share and $1.19 per diluted share. Earnings per Share Basic earnings per share is calculated using our weighted-average outstanding common shares. Diluted earnings per share is calculated using our weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method. In periods when we have a net loss, stock awards are excluded from our calculation of earnings per share as their inclusion would have an antidilutive effect. The following table shows the calculation of diluted shares (in millions): Three Months Ended 2019 2020 Shares used in computation of basic earnings per share 491 498 Total dilutive effect of outstanding stock awards 11 8 Shares used in computation of diluted earnings per share 502 506 Inventories Inventories, consisting of products available for sale, are primarily accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category. The inventory valuation allowance, representing a write-down of inventory, was $1.6 billion as of December 31, 2019 and March 31, 2020 . Accounts Receivable, Net and Other Included in “Accounts receivable, net and other” on our consolidated balance sheets are amounts primarily related to customers, vendors, and sellers. As of December 31, 2019 and March 31, 2020 , customer receivables, net, were $12.6 billion and $11.3 billion , vendor receivables, net, were $4.2 billion and $2.7 billion , and seller receivables, net, were $863 million and $801 million . Seller receivables are amounts due from sellers related to our seller lending program, which provides funding to sellers primarily to procure inventory. We estimate losses on receivables based on expected losses, including our historical experience of actual losses. The allowance for doubtful accounts was $718 million and $1.1 billion as of December 31, 2019 and March 31, 2020. Digital Video and Music Content The total capitalized costs of video, which is primarily released content, and music as of December 31, 2019 and March 31, 2020 were $5.8 billion and $6.1 billion . Total video and music expense was $1.7 billion and $2.4 billion in Q1 2019 and Q1 2020 . Unearned Revenue Unearned revenue is recorded when payments are received or due in advance of performing our service obligations and is recognized over the service period. Unearned revenue primarily relates to prepayments of AWS services and Amazon Prime memberships. Our total unearned revenue as of December 31, 2019 was $10.2 billion , of which $3.4 billion was recognized as revenue during the three months ended March 31, 2020 . Included in “Other long-term liabilities” on our consolidated balance sheets was $2.0 billion and $1.8 billion of unearned revenue as of December 31, 2019 and March 31, 2020 . Additionally, we have performance obligations, primarily related to AWS, associated with commitments in customer contracts for future services that have not yet been recognized in our financial statements. For contracts with original terms that exceed one year, those commitments not yet recognized were $34.1 billion as of March 31, 2020 . The weighted average remaining life of our long-term contracts is 3.3 years . However, the amount and timing of revenue recognition is largely driven by customer usage, which can extend beyond the original contractual term.

Investments, Debt and Equity Securities [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Cash, Cash Equivalents, Restricted Cash, and Marketable Securities As of December 31, 2019 and March 31, 2020 , our cash, cash equivalents, restricted cash, and marketable securities primarily consisted of cash, AAA-rated money market funds, U.S. and foreign government and agency securities, and other investment grade securities. Cash equivalents and marketable securities are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value: Level 1 —Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 —Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 —Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. We measure the fair value of money market funds and certain marketable equity securities based on quoted prices in active markets for identical assets or liabilities. Other marketable securities were valued either based on recent trades of securities in inactive markets or based on quoted market prices of similar instruments and other significant inputs derived from or corroborated by observable market data. We did not hold significant amounts of cash, cash equivalents, restricted cash, or marketable securities categorized as Level 3 assets as of December 31, 2019 and March 31, 2020 . The following table summarizes, by major security type, our cash, cash equivalents, restricted cash, and marketable securities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in millions): December 31, 2019 March 31, 2020 Total Cost or Gross Gross Total Cash $ 9,776 $ 8,363 $ — $ — $ 8,363 Level 1 securities: Money market funds 18,850 16,260 — — 16,260 Equity securities (1) 202 174 Level 2 securities: Foreign government and agency securities 4,794 3,467 — (1 ) 3,466 U.S. government and agency securities 7,080 4,295 51 (1 ) 4,345 Corporate debt securities 11,881 13,957 41 (205 ) 13,793 Asset-backed securities 2,360 2,868 3 (51 ) 2,820 Other fixed income securities 394 375 2 (1 ) 376 Equity securities (1) 5 2 $ 55,342 $ 49,585 $ 97 $ (259 ) $ 49,599 Less: Restricted cash, cash equivalents, and marketable securities (2) (321 ) (307 ) Total cash, cash equivalents, and marketable securities $ 55,021 $ 49,292 ___________________ (1) The related unrealized gain (loss) recorded in “Other income (expense), net” was $68 million and $(31) million in Q1 2019 and Q1 2020 . (2) We are required to pledge or otherwise restrict a portion of our cash, cash equivalents, and marketable securities as collateral for real estate leases, amounts due to third-party sellers in certain jurisdictions, debt, and standby and trade letters of credit. We classify cash, cash equivalents, and marketable securities with use restrictions of less than twelve months as “Accounts receivable, net and other” and of twelve months or longer as non-current “Other assets” on our consolidated balance sheets. See “Note 4 — Commitments and Contingencies.” The following table summarizes the remaining contractual maturities of our cash equivalents and marketable fixed income securities as of March 31, 2020 (in millions): Amortized Cost Estimated Fair Value Due within one year $ 26,936 $ 26,935 Due after one year through five years 11,645 11,498 Due after five years through ten years 533 527 Due after ten years 2,108 2,100 Total $ 41,222 $ 41,060 Actual maturities may differ from the contractual maturities because borrowers may have certain prepayment conditions. Equity Warrants and Non-Marketable Equity Investments We hold equity warrants giving us the right to acquire stock of other companies. As of December 31, 2019 and March 31, 2020 , these warrants had a fair value of $669 million and $528 million , and are recorded within “Other assets” on our consolidated balance sheets. These assets are primarily classified as Level 2 assets. As of December 31, 2019 and March 31, 2020 , equity investments not accounted for under the equity-method and without readily determinable fair values, had a carrying value of $1.5 billion , and are recorded within “Other assets” on our consolidated balance sheets with adjustments recognized in “Other income (expense), net” on our consolidated statements of operations. Consolidated Statements of Cash Flows Reconciliation The following table provides a reconciliation of the amount of cash, cash equivalents, and restricted cash reported within the consolidated balance sheets to the total of the same such amounts shown in the consolidated statements of cash flows (in millions): December 31, 2019 March 31, 2020 Cash and cash equivalents $ 36,092 $ 27,201 Restricted cash included in accounts receivable, net and other 276 282 Restricted cash included in other assets 42 22 Total cash, cash equivalents, and restricted cash shown in the consolidated statements of cash flows $ 36,410 $ 27,505

The consumer products included books, music, other media, apparel, home and kitchen, health and beauty, jewelry, office, consumer electronics, software, lawn and patio, grocery, and automotive products. Our review is ongoing and we have voluntarily reported these orders to the United States Treasury Department’s Office of Foreign Assets Control and the United States Department of Commerce’s Bureau of Industry and Security. In March 2020, BIS notified us that it had completed and closed its review with the issuance of a Warning Letter. We intend to cooperate fully with OFAC with respect to its review, which may result in the imposition of penalties. For additional information, see Item 5 of Part II, “Other Information — Disclosure Pursuant to Section 13(r) of the Exchange Act.” We are subject to claims related to various indirect taxes (such as sales, value added, consumption, service, and similar taxes), including in jurisdictions in which we already collect and remit such taxes. If the relevant taxing authorities were successfully to pursue these claims, we could be subject to significant additional tax liabilities. For example, in June 2017, the State of South Carolina issued an assessment for uncollected sales and use taxes for the period from January 2016 to March 2016, including interest and penalties. South Carolina is alleging that we should have collected sales and use taxes on transactions by our third-party sellers. In September 2019, the South Carolina Administrative Law Court ruled in favor of the Department of Revenue and we have appealed the decision to the state Court of Appeals. We believe the assessment is without merit and intend to defend ourselves vigorously in this matter. If other tax authorities were successfully to seek additional adjustments of a similar nature, we could be subject to significant additional tax liabilities. Legal Proceedings The Company is involved from time to time in claims, proceedings, and litigation, including the matters described in Item 8 of Part II, “Financial Statements and Supplementary Data — Note 7 — Commitments and Contingencies — Legal Proceedings” of our 2019 Annual Report on Form 10-K as supplemented by the following: Beginning in March 2020, a number of class-action complaints were filed in the United States District Court for the Western District of Washington, the Superior Court of Quebec - Division of Montreal, and the Federal Court of Canada against Amazon.com, Inc. and related entities. The complaints allege, among other things, a price fixing arrangement between Amazon.com, Inc. and third-party sellers in Amazon’s stores, monopolization and attempted monopolization of an alleged online retail market or submarkets, and consumer protection and unjust enrichment claims. The complaints allege several distinct purported classes, including consumers who purchased a product through Amazon’s stores and consumers who purchased a product offered by Amazon through another e-commerce retailer. The complaints seek billions of dollars of alleged actual damages, treble damages, punitive damages, and injunctive relief. We dispute the allegations of wrongdoing and intend to defend ourselves vigorously in these matters. In addition, we are regularly subject to claims, litigation, and other proceedings, including potential regulatory proceedings, involving patent and other intellectual property matters, taxes, labor and employment, competition and antitrust, privacy and data protection, consumer protection, commercial disputes, goods and services offered by us and by third parties, and other matters. The outcomes of our legal proceedings and other contingencies are inherently unpredictable, subject to significant uncertainties, and could be material to our operating results and cash flows for a particular period. We evaluate, on a regular basis, developments in our legal proceedings and other contingencies that could affect the amount of liability, including amounts in excess of any previous accruals and reasonably possible losses disclosed, and make adjustments and changes to our accruals and disclosures as appropriate. For the matters we disclose that do not include an estimate of the amount of loss or range of losses, such an estimate is not possible or is immaterial, and we may be unable to estimate the possible loss or range of losses that could potentially result from the application of non-monetary remedies. Until the final resolution of such matters, if any of our estimates and assumptions change or prove to have been incorrect, we may experience losses in excess of the amounts recorded, which could have a material effect on our business, consolidated financial position, results of operations, or cash flows.

(3) Issued in August 2017, effective interest rates of the 2020, 2023, 2024, 2027, 2037, 2047, and 2057 Notes were 2.16% , 2.56% , 2.95% , 3.25% , 3.94% , 4.13% , and 4.33% . (4) Consists of $872 million of 2025 Notes issued in December 2017 in exchange for notes assumed in connection with the acquisition of Whole Foods Market and $128 million of 2025 Notes issued by Whole Foods Market that did not participate in our December 2017 exchange offer. The effective interest rate of the 2025 Notes was 3.02% . Interest on the Notes issued in 2012 is payable semi-annually in arrears in May and November. Interest on the Notes issued in 2014 is payable semi-annually in arrears in June and December. Interest on the Notes issued in 2017 is payable semi-annually in arrears in February and August. Interest on the 2025 Notes is payable semi-annually in arrears in June and December. We may redeem the Notes at any time in whole, or from time to time, in part at specified redemption prices. We are not subject to any financial covenants under the Notes. The proceeds from the November 2012 and the December 2014 Notes were used for general corporate purposes. The proceeds from the August 2017 Notes were used to fund the consideration for the acquisition of Whole Foods Market, to repay notes due in 2017, and for general corporate purposes. The estimated fair value of the Notes was approximately $26.2 billion and $27.5 billion as of December 31, 2019 and March 31, 2020 , which is based on quoted prices for our debt as of those dates. In October 2016, we entered into a $500 million secured revolving credit facility with a lender that is secured by certain seller receivables, which we subsequently increased to $740 million and may from time to time increase in the future subject to lender approval (the “Credit Facility”). The Credit Facility is available until October 2022, bears interest at the London interbank offered rate (“LIBOR”) plus 1.40% , and has a commitment fee of 0.50% on the undrawn portion. There were $740 million of borrowings outstanding under the Credit Facility as of December 31, 2019 and March 31, 2020 , which had a weighted-average interest rate of 3.4% and 3.3% as of December 31, 2019 and March 31, 2020 . As of December 31, 2019 and March 31, 2020 , we have pledged $852 million and $848 million of our cash and seller receivables as collateral for debt related to our Credit Facility. The estimated fair value of the Credit Facility, which is based on Level 2 inputs, approximated its carrying value as of December 31, 2019 and March 31, 2020 . Other long-term debt, including the current portion, had a weighted-average interest rate of 4.1% and 3.9% as of December 31, 2019 and March 31, 2020 . We used the net proceeds from the issuance of this debt primarily to fund certain business operations. The estimated fair value of other long-term debt, which is based on Level 2 inputs, approximated its carrying value as of December 31, 2019 and March 31, 2020 . In April 2018, we established a commercial paper program (the “Commercial Paper Program”) under which we may from time to time issue unsecured commercial paper up to a total of $7.0 billion at any time, with individual maturities that may vary but will not exceed 397 days from the date of issue. There were no borrowings outstanding under the Commercial Paper Program as of December 31, 2019 and March 31, 2020 . In April 2020, we issued $1.1 billion under the Commercial Paper Program. In April 2018, in connection with our Commercial Paper Program, we amended and restated our unsecured revolving credit facility (the “Credit Agreement”) with a syndicate of lenders to increase our borrowing capacity thereunder to $7.0 billion . As amended and restated, the Credit Agreement has a term of three years , but it may be extended for up to three additional one -year terms if approved by the lenders. The interest rate applicable to outstanding balances under the amended and restated Credit Agreement is LIBOR plus 0.50% , with a commitment fee of 0.04% on the undrawn portion of the credit facility. There were no borrowings outstanding under the Credit Agreement as of December 31, 2019 and March 31, 2020 .

There were no repurchases of common stock during the three months ended March 31, 2019 or 2020 . Stock Award Activity Common shares outstanding plus shares underlying outstanding stock awards totaled 512 million and 513 million as of December 31, 2019 and March 31, 2020 . These totals include all vested and unvested stock awards outstanding, including those awards we estimate will be forfeited.

Income Taxes

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our tax provision or benefit from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, intercompany transactions, the applicability of special tax regimes, changes in how we do business, acquisitions, investments, audit-related developments, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, foreign currency gains (losses), changes in statutes, regulations, case law, and administrative practices, principles, and interpretations related to tax, including changes to the global tax framework, competition, and other laws and accounting rules in various jurisdictions, and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower. For 2020 , we estimate that our effective tax rate will be favorably affected by the impact of excess tax benefits from stock-based compensation and the U.S. federal research and development credit and adversely affected by state income taxes and losses incurred in certain foreign jurisdictions for which we may not realize a tax benefit. Losses for which we may not realize a related tax benefit, primarily due to losses of foreign subsidiaries, reduce our pre-tax income without a corresponding reduction in our tax expense, and therefore increase our effective tax rate. We record valuation allowances against the deferred tax assets associated with losses for which we may not realize a related tax benefit. Our income tax provisions for the three months ended March 31, 2019 and 2020 were $836 million and $744 million , which included $261 million and $273 million of net discrete tax benefits primarily attributable to excess tax benefits from stock-based compensation. Cash paid for income taxes, net of refunds was $168 million and $305 million in Q1 2019 and Q1 2020 . As of December 31, 2019 and March 31, 2020 , tax contingencies were approximately $3.9 billion and $3.8 billion . Changes in state, federal, and foreign tax laws may increase our tax contingencies. The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ from the amounts accrued. It is reasonably possible that within the next twelve months we will receive additional assessments by various tax authorities or possibly reach resolution of income tax examinations in one or more jurisdictions. These assessments or settlements could result in changes to our contingencies related to positions on prior years’ tax filings. We are under examination, or may be subject to examination, by the Internal Revenue Service (“IRS”) for the calendar year 2007 and thereafter. These examinations may lead to ordinary course adjustments or proposed adjustments to our taxes or our net operating losses with respect to years under examination as well as subsequent periods. In October 2014, the European Commission opened a formal investigation to examine whether decisions by the tax authorities in Luxembourg with regard to the corporate income tax paid by certain of our subsidiaries comply with European Union rules on state aid. On October 4, 2017, the European Commission announced its decision that determinations by the tax authorities in Luxembourg did not comply with European Union rules on state aid. Based on that decision the European Commission announced an estimated recovery amount of approximately €250 million , plus interest, for the period May 2006 through June 2014, and ordered Luxembourg tax authorities to calculate the actual amount of additional taxes subject to recovery. Luxembourg computed an initial recovery amount, consistent with the European Commission’s decision, that we deposited into escrow in March 2018, subject to adjustment pending conclusion of all appeals. In December 2017, Luxembourg appealed the European Commission’s decision. In May 2018, we appealed. We believe the European Commission’s decision to be without merit and will continue to defend ourselves vigorously in this matter. We are also subject to taxation in various states and other foreign jurisdictions including China, Germany, India, Japan, Luxembourg, and the United Kingdom. We are under, or may be subject to, audit or examination and additional assessments by the relevant authorities in respect of these particular jurisdictions primarily for 2009 and thereafter.

Segment Information

Segment Information	Mar. 31, 2020
Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION We have organized our operations into three segments: North America, International, and AWS. We allocate to segment results the operating expenses “Fulfillment,” “Technology and content,” “Marketing,” and “General and administrative” based on usage, which is generally reflected in the segment in which the costs are incurred. The majority of technology infrastructure costs are allocated to the AWS segment based on usage. The majority of the remaining non-infrastructure technology costs are incurred in the U.S. and are allocated to our North America segment. There are no internal revenue transactions between our reportable segments. These segments reflect the way our chief operating decision maker evaluates the Company’s business performance and manages its operations. North America The North America segment primarily consists of amounts earned from retail sales of consumer products (including from sellers) and subscriptions through North America-focused online and physical stores. This segment includes export sales from these online stores. International The International segment primarily consists of amounts earned from retail sales of consumer products (including from sellers) and subscriptions through internationally-focused online stores. This segment includes export sales from these internationally-focused online stores (including export sales from these online stores to customers in the U.S., Mexico, and Canada), but excludes export sales from our North America-focused online stores. AWS The AWS segment consists of amounts earned from global sales of compute, storage, database, and other service offerings for start-ups, enterprises, government agencies, and academic institutions. Information on reportable segments and reconciliation to consolidated net income is as follows (in millions): Three Months Ended 2019 2020 North America Net sales $ 35,812 $ 46,127 Operating expenses 33,525 44,815 Operating income $ 2,287 $ 1,312 International Net sales $ 16,192 $ 19,106 Operating expenses 16,282 19,504 Operating income (loss) $ (90 ) $ (398 ) AWS Net sales $ 7,696 $ 10,219 Operating expenses 5,473 7,144 Operating income $ 2,223 $ 3,075 Consolidated Net sales $ 59,700 $ 75,452 Operating expenses 55,280 71,463 Operating income 4,420 3,989 Total non-operating income (expense) (19 ) (606 ) Provision for income taxes (836 ) (744 ) Equity-method investment activity, net of tax (4 ) (104 ) Net income $ 3,561 $ 2,535 Net sales by groups of similar products and services, which also have similar economic characteristics, is as follows (in millions): Three Months Ended 2019 2020 Net Sales: Online stores (1) $ 29,498 $ 36,652 Physical stores (2) 4,307 4,640 Third-party seller services (3) 11,141 14,479 Subscription services (4) 4,342 5,556 AWS 7,696 10,219 Other (5) 2,716 3,906 Consolidated $ 59,700 $ 75,452 ____________________________ (1) Includes product sales and digital media content where we record revenue gross.

Accounting Policies [Abstract]
Inventory, Policy [Policy Text Block]	Inventories Inventories, consisting of products available for sale, are primarily accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category. The inventory valuation allowance, representing a write-down of inventory, was $1.6 billion as of December 31, 2019 and March 31, 2020 .
Video And Music Content, Policy [Policy Text Block]	Digital Video and Music Content The total capitalized costs of video, which is primarily released content, and music as of December 31, 2019 and March 31, 2020 were $5.8 billion and $6.1 billion . Total video and music expense was $1.7 billion and $2.4 billion in Q1 2019 and Q1 2020
Unaudited Interim Financial Information	Unaudited Interim Financial Information We have prepared the accompanying consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. These consolidated financial statements are unaudited and, in our opinion, include all adjustments, consisting of normal recurring adjustments and accruals necessary for a fair presentation of our consolidated cash flows, operating results, and balance sheets for the periods presented. Operating results for the periods presented are not necessarily indicative of the results that may be expected for 2020 due to seasonal and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted in accordance with the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes in Item 8 of Part II, “Financial Statements and Supplementary Data,” of our 2019 Annual Report on Form 10-K.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation
Use of Estimates	Use of Estimates
Earnings per Share	Earnings per Share Basic earnings per share is calculated using our weighted-average outstanding common shares. Diluted earnings per share is calculated using our weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method. In periods when we have a net loss, stock awards are excluded from our calculation of earnings per share as their inclusion would have an antidilutive effect.
Accounts Receivable, Net and Other	Accounts Receivable, Net and Other Included in “Accounts receivable, net and other” on our consolidated balance sheets are amounts primarily related to customers, vendors, and sellers. As of December 31, 2019 and March 31, 2020 , customer receivables, net, were $12.6 billion and $11.3 billion , vendor receivables, net, were $4.2 billion and $2.7 billion , and seller receivables, net, were $863 million and $801 million . Seller receivables are amounts due from sellers related to our seller lending program, which provides funding to sellers primarily to procure inventory.
Unearned Revenue	Unearned Revenue Unearned revenue is recorded when payments are received or due in advance of performing our service obligations and is recognized over the service period. Unearned revenue primarily relates to prepayments of AWS services and Amazon Prime memberships. Our total unearned revenue as of December 31, 2019 was $10.2 billion , of which $3.4 billion was recognized as revenue during the three months ended March 31, 2020 . Included in “Other long-term liabilities” on our consolidated balance sheets was $2.0 billion and $1.8 billion of unearned revenue as of December 31, 2019 and March 31, 2020 . Additionally, we have performance obligations, primarily related to AWS, associated with commitments in customer contracts for future services that have not yet been recognized in our financial statements. For contracts with original terms that exceed one year, those commitments not yet recognized were $34.1 billion as of March 31, 2020 . The weighted average remaining life of our long-term contracts is 3.3 years . However, the amount and timing of revenue recognition is largely driven by customer usage, which can extend beyond the original contractual term.
