Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated condensed financial statements of Cintas Corporation (Cintas, the Company, we, us or our) included herein have been prepared by Cintas, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. While we believe that the disclosures are adequately presented, we suggest that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021. A summary of our significant accounting policies is presented beginning on page 40 of that report. There have been no material changes in the accounting policies followed by Cintas during the current fiscal year. Interim results are subject to variations and are not necessarily indicative of the results of operations for a full fiscal year. In the opinion of management, adjustments (which include only normal recurring adjustments) necessary for a fair statement of the consolidated results of the interim periods shown have been made. Inventories, net are valued at the lower of cost (first-in, first-out) or net realizable value. Inventory is comprised of the following: (In thousands) November 30, 2021 May 31, Raw materials $ 16,385 $ 15,109 Work in process 35,328 37,664 Finished goods 413,151 429,024 $ 464,864 $ 481,797 Inventories are recorded net of reserves for obsolete inventory (excess and slow-moving) of $106.6 million and $111.0 million at November 30, 2021 and May 31, 2021, respectively. The inventory obsolescence reserve is determined by specific identification, as well as an estimate based on Cintas' historical rates of obsolescence. Once a specific inventory item is written down to the lower of cost or net realizable value, a new cost basis has been established, and that inventory item cannot subsequently be marked up. Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current year presentation. The reclassification has been reflected in the consolidated condensed balance sheet and consolidated condensed statement of shareholders' equity for the fiscal year ended May 31, 2021 and the three and six months ended November 30, 2020, to combine common stock and paid-in capital for presentation purposes. These reclassifications had no effect on the Company's reported results of operations. New Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . ASU 2019-12 is part of the FASB’s overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. ASU 2019-12 removes certain exceptions to the general principles of Accounting Standards Codification (ASC) 740, Income Taxes (ASC 740), in order to reduce the cost and complexity of its application in the areas of intraperiod tax allocation, deferred tax liabilities related to outside basis differences, year-to-date losses in interim periods and other areas within ASC 740. The Company adopted ASU 2019-12 on June 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated condensed financial statements currently but may in future periods. No other new accounting pronouncement recently issued or newly effective had, or is expected to have, a material impact on Cintas' consolidated condensed financial statements.

Revenue Recognition Policy Approximately 95% of the Company's revenue is derived from fees for route servicing of Uniform Rental and Facility Services, First Aid and Safety Services and Fire Protection Services customers, performed by a Cintas employee-partner, at the customer's location of business. Revenues from our route servicing customer contracts represent a single-performance obligation. The Company recognizes revenues over time as services are performed based on the nature of services provided and contractual rates (output method) or at a point in time when the performance obligation under the terms of the contract with a customer are satisfied, at the customer's location of business. The Company's remaining revenue, primarily within the Uniform Direct Sales operating segment, and representing approximately 5% of the Company's total revenue, is recognized when the obligations under the terms of a contract with a customer are satisfied. This generally occurs when the goods are transferred to the customer. Revenue recorded is presented net of sales and other taxes we collect on behalf of governmental authorities. Shipping and handling costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Certain of our customer contracts, include pricing terms and conditions that include components of variable consideration. The variable consideration is typically in the form of consideration paid to a customer based on performance metrics specified within the contract. Specifically, some contracts contain discounts or rebates that the customer can earn through the achievement of specified volume levels. Each component of variable consideration is earned based on the Company's actual performance during the measurement period specified within the contract. To determine the transaction price, the Company estimates the variable consideration using the most likely amount method, based on the specific contract provisions and known performance results during the relevant measurement period. When determining if variable consideration should be constrained, the Company considers whether factors outside its control could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal. The Company's performance period generally corresponds with the monthly invoice period. No constraints on our revenue recognition were applied during the three or six months ended November 30, 2021 or 2020. The Company reassesses these estimates during each reporting period. Cintas maintains a liability for these discounts and rebates within accrued liabilities on the consolidated condensed balance sheets. Variable consideration also includes consideration paid to a customer at the beginning of a contract. Cintas capitalizes this consideration and amortizes it over the life of the contract as a reduction to revenue. These assets are included in prepaid expenses and other current assets and in other assets, net on the consolidated condensed balance sheets. Additionally, certain Uniform Direct Sales operating segment customer contracts contain a provision with an enforceable right of payment, and the underlying product has no alternative use to Cintas. Consequently, when both aforementioned provisions are prevalent in a customer contract, the revenue is recorded for finished goods that the customer is obligated to purchase under the termination terms of the contract. We are exposed to credit losses primarily through our trade receivables. We determine the allowance for credit losses using both an estimate, based on historical rates of collections, and reserves for specific accounts identified as uncollectible. The portion of the allowance that is an estimate based on Cintas' historical rates of collections is recorded for overdue amounts, beginning with a nominal percentage when the account is current and increasing substantially as the account ages. The amount provided as the account ages will differ slightly between the Uniform Rental and Facility Services reportable operating segment, the First Aid and Safety Services reportable operating segment and All Other because of differences in customers served and the nature of each business. We update our estimate of credit loss reserves quarterly, considering recent write-offs and collections information and underlying economic expectations. Costs to Obtain a Contract The Company capitalizes commission expenses paid to our employee-partners when the commissions are deemed to be incremental for obtaining the route servicing customer contract. As permitted by ASC 606, "Revenue from Contracts with Customers (Topic 606)", the Company has elected to apply the guidance to a portfolio of contracts (or performance obligations) with similar characteristics because the Company reasonably expects that the effects on the consolidated condensed financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts within the portfolio. The Company also continues to expense certain costs to obtain a contract if those costs do not meet the criteria of the standard or the amortization period of the asset would have been one year or less. The deferred commissions are amortized on a straight-line basis over the expected period of benefit. We review the deferred commission balances for impairment on an ongoing basis. Deferred commissions are classified as current or noncurrent based on the timing of when we expect to recognize the expense. The current portion is included in prepaid expenses and other current assets and the noncurrent portion is included in other assets, net on the Company's consolidated condensed balance sheets. As of November 30, 2021, the current and noncurrent assets related to deferred commissions totaled $81.3 million and $228.9 million, respectively. As of May 31, 2021, the current and noncurrent assets related to deferred commissions totaled $79.4 million and $227.1 million, respectively. We recorded amortization expense related to deferred commissions of $21.7 million and $20.7 million during the three months ended November 30, 2021 and 2020, respectively. During the six months ended November 30, 2021 and 2020, we recorded amortization expense related to deferred commissions of $43.1 million and $41.1 million, respectively. These expenses are classified in selling and administrative expenses on the consolidated condensed statements of income.

Leases

Leases	Nov. 30, 2021
Leases [Abstract]
Leases	Leases Cintas has operating leases for certain operating facilities, vehicles and equipment, which provide the right to use the underlying asset and require lease payments over the term of the lease. Each new contract is evaluated to determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. All identified leases are recorded on the consolidated condensed balance sheet with a corresponding operating lease right-of-use asset, net, representing the right to use the underlying asset for the lease term and the operating lease liabilities representing the obligation to make lease payments arising from the lease. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the consolidated condensed balance sheet. Operating lease right-of-use assets, net and operating lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term and include options to extend or terminate the lease when they are reasonably certain to be exercised. The present value of lease payments is determined primarily using the incremental borrowing rate based on the information available at lease commencement date. Lease expense for operating leases is recorded on a straight-line basis over the lease term and variable lease costs are recorded as incurred. Both lease expense and variable lease costs are primarily recorded in cost of uniform rental and facility services and other on the Company's consolidated condensed statements of income. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Operating lease costs, including short-term lease expense and variable lease costs which were immaterial in both periods, were $18.0 million and $18.1 million for the three months ended November 30, 2021 and 2020, respectively. For the six months ended November 30, 2021 and 2020, operating lease costs, including short-term lease expense and variable lease costs which were immaterial in both periods, were $36.2 million and $35.2 million, respectively. The following table provides supplemental information related to the Company's consolidated condensed statements of cash flows for the six months ended November 30: (In thousands) 2021 2020 Cash paid for amounts included in the measurement of operating lease liabilities $ 24,301 $ 24,565 Operating lease right-of-use assets obtained in exchange for new and renewed $ 10,609 $ 15,735 Other information related to the operating lease right-of-use assets, net and operating lease liabilities was as follows: November 30, May 31, Weighted-average remaining lease term - operating leases 5.15 years 5.33 years Weighted-average discount rate - operating leases 2.23% 2.32% The contractual future minimum lease payments of Cintas' operating lease liabilities by fiscal year are as follows as of November 30, 2021: (In thousands) 2022 (remaining six months) $ 23,998 2023 41,926 2024 31,483 2025 23,829 2026 18,126 Thereafter 32,379 Total payments 171,741 Less interest (9,693) Total present value of lease payments $ 162,048

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements All financial instruments that are measured at fair value on a recurring basis (at least annually) have been classified within the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the consolidated condensed balance sheet date. These financial instruments measured at fair value on a recurring basis are summarized below: As of November 30, 2021 (In thousands) Level 1 Level 2 Level 3 Fair Value Cash and cash equivalents $ 113,170 $ — $ — $ 113,170 Other assets, net: Interest rate lock agreements — 16,202 — 16,202 Total assets at fair value $ 113,170 $ 16,202 $ — $ 129,372 Current accrued liabilities: Interest rate lock agreements $ — $ 71,918 $ — $ 71,918 Total liabilities at fair value $ — $ 71,918 $ — $ 71,918 As of May 31, 2021 (In thousands) Level 1 Level 2 Level 3 Fair Value Cash and cash equivalents $ 493,640 $ — $ — $ 493,640 Other assets, net: Interest rate lock agreements — 40,400 — 40,400 Total assets at fair value $ 493,640 $ 40,400 $ — $ 534,040 Long-term accrued liabilities: Interest rate lock agreements $ — $ 61,567 $ — $ 61,567 Total liabilities at fair value $ — $ 61,567 $ — $ 61,567 Cintas’ cash and cash equivalents are generally classified within Level 1 or Level 2 of the fair value hierarchy. Financial instruments classified as Level 1 are based on quoted market prices in active markets, and financial instruments classified as Level 2 are based on quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The types of financial instruments Cintas classifies within Level 1 include most bank deposits and money market securities. Cintas does not adjust the quoted market price for such financial instruments. The fair values of Cintas' interest rate lock agreements are based on similar exchange traded derivatives (market approach) and are, therefore, included within Level 2 of the fair value hierarchy. The fair value was determined by comparing the locked rates against the benchmarked treasury rate. No other amounts included in other assets, net, current accrued liabilities or long-term accrued liabilities are recorded at fair value on a recurring basis. The methods described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while Cintas believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the consolidated condensed balance sheet dates. In addition to assets and liabilities that are recorded at fair value on a recurring basis, Cintas records assets and liabilities at fair value on a nonrecurring basis as required under U.S. GAAP. The assets and liabilities measured at fair value on a nonrecurring basis primarily relate to assets and liabilities acquired in a business acquisition, which were not material during the three or six months ended

For the six months ended November 30, 2021 and 2020, options granted to purchase 0.1 million and 0.2 million shares of Cintas common stock, respectively, were excluded from the computation of diluted earnings per share. The exercise prices of these options were greater than the average market price of the common stock (anti-dilutive). On October 29, 2019, Cintas announced that the Board of Directors authorized a $1.0 billion share buyback program, which was completed during the first quarter of fiscal 2022. From the inception of the October 29, 2019 share buyback program through July 2021, Cintas purchased a total of 2.8 million shares of Cintas common stock at an average price of $358.93 per share for a total purchase price of $1.0 billion. On July 27, 2021, Cintas announced that the Board of Directors authorized a new $1.5 billion share buyback program, which does not have an expiration date.

The rate presented is the variable borrowing rate at November 30, 2021. (2) Cintas assumed these senior notes with the acquisition of G&K Services, Inc. (G&K) in the fourth quarter of fiscal 2017, and they were recorded at fair value. The interest rate shown above is the effective interest rate. The principal amount of these notes is $50.0 million with a stated interest rate of 3.73%. (3) Cintas assumed these senior notes with the acquisition of G&K in the fourth quarter of fiscal 2017, and they were recorded at fair value. The interest rate shown above is the effective interest rate. The principal amount of these notes is $50.0 million with a stated interest rate of 3.88%. Cintas' senior notes, excluding the G&K senior notes assumed with the acquisition of G&K in fiscal 2017, are recorded at cost, net of debt issuance costs. The fair value of the long-term debt is estimated using Level 2 inputs based on general market prices. The carrying value and fair value of Cintas' debt as of November 30, 2021 were $2,467.0 million and $2,540.7 million, respectively, and as of May 31, 2021 were $2,550.0 million and $2,788.8 million, respectively. On June 1, 2021, in accordance with the terms of the notes, Cintas paid the $250.0 million aggregate principal amount of its 4.30%, 10-year senior notes that matured on that date with cash on hand. During the six months ended November 30, 2021, Cintas issued $167.0 million, net of commercial paper borrowings. The credit agreement that supports our commercial paper program has a revolving credit facility with a capacity of $1.0 billion. The credit agreement has an accordion feature that provides Cintas the ability to request increases to the borrowing commitments under the revolving credit facility of up to $250.0 million in the aggregate, subject to customary conditions. The maturity date of the revolving credit facility is May 23, 2024 . As of November 30, 2021, there was $167.0 million of commercial paper outstanding with maturity dates less than 30 days and with a weighted average interest rate of 0.22% and there was no borrowings on our revolving credit facility. As of May 31, 2021, t her e was no commercial paper outstanding and no borrowings on our revolving credit facility. Cintas uses interest rate locks to manage its overall interest expense as interest rate locks effectively change the interest rate of specific debt issuances. The interest rate locks are entered into to protect against unfavorable movements in the benchmark treasury rate related to forecasted debt issuances. Cintas used interest rate locks, which represent cash flow hedges, to hedge against movements in the treasury rates at the time Cintas issued its senior notes in fiscal 2007, fiscal 2012, fiscal 2013 and fiscal 2017. The amortization of the interest rate locks resulted in a decrease to other comprehensive income of $0.4 million for both the three months ended November 30, 2021 and 2020. For the six months ended November 30, 2021 and 2020, the amortization of the interest rate locks resulted in a decrease to other comprehensive income of $0.9 million and $0.7 million, respectively. During fiscal 2020 and fiscal 2019, Cintas entered into interest rate lock agreements with a total notional value of $950.0 million and $500.0 million, respectively, for forecasted debt issuances in connection with upcoming debt maturities. The fair values of the outstanding interest rate lock agreements are summarized as follows: November 30, 2021 May 31, 2021 Fiscal Year of Issuance (in thousands) Notional Other Current Other Long-term 2020 $ 950,000 $ 16,202 $ 966 $ 40,400 $ — 2019 $ 500,000 $ — $ 70,952 $ — $ 61,657 The interest rate locks are also recorded in other comprehensive income (loss), net of tax. These interest rate locks had no impact on net income or cash flows for the three and six months ended November 30, 2021 or 2020. Cintas has certain covenants related to debt agreements. These covenants limit Cintas' ability to incur certain liens, to engage in sale-leaseback transactions and to merge, consolidate or sell all or substantially all of Cintas' assets. These covenants also require Cintas to maintain certain debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) and interest coverage ratios. Cross-default provisions exist between certain debt instruments. If a default of a significant covenant were to occur, the default could result in an acceleration of the maturity of the indebtedness, impair liquidity and limit the ability to raise future capital. Cintas was in compliance with all of the debt covenants for all periods presented.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In the normal course of business, Cintas provides for uncertain tax positions and the related interest and adjusts its unrecognized tax benefits and accrued interest accordingly. As of November 30, 2021 and May 31, 2021, recorded unrecognized tax benefits were $31.1 million and $34.2 million, respectively, and are included in long-term accrued liabilities on the consolidated condensed balance sheets. The majority of Cintas' operations are in North America. Cintas is required to file federal income tax returns, as well as state income tax returns in a majority of the domestic states and also in certain Canadian provinces. At times, Cintas is subject to audits in these jurisdictions. The audits, by nature, are sometimes complex and can require several years to resolve. The final resolution of any such tax audit could result in either a reduction in Cintas' accruals or an increase in its income tax provision, either of which could have an impact on the consolidated results of operations in any given period. All United States federal income tax returns are closed to audit through fiscal 2017. Cintas is currently in various audits in certain foreign jurisdictions and certain domestic states. The years under foreign and domestic state audits cover fiscal years back to 2014. Based on the resolution of the various audits and other potential regulatory developments, it is reasonably possible that the balance of unrecognized tax benefits would not change for the fiscal year ending May 31, 2022. Cintas’ effective tax rate was 18.0% and 13.3% for the three months ended November 30, 2021 and 2020, respectively. For the six months ended November 30, 2021 and 2020, Cintas' effective tax rate was 14.5% and 10.5%, respectively. The effective tax rate for all periods was impacted by certain discrete items (primarily the tax accounting for stock-based compensation). In addition, the effective tax rate for the three and six months ended November 30, 2020 included a one-time tax benefit on the sale of certain operating assets.

Segment Reporting [Abstract]
Segment Information	Segment Information Cintas’ reportable operating segments are Uniform Rental and Facility Services and First Aid and Safety Services. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies, and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services. The remainder of Cintas’ operating segments, which consists of the Fire Protection Services operating segment and the Uniform Direct Sale operating segment, is included in All Other.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The consolidated condensed financial statements of Cintas Corporation (Cintas, the Company, we, us or our) included herein have been prepared by Cintas, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. While we believe that the disclosures are adequately presented, we suggest that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021. A summary of our significant accounting policies is presented beginning on page 40 of that report. There have been no material changes in the accounting policies followed by Cintas during the current fiscal year. Interim results are subject to variations and are not necessarily indicative of the results of operations for a full fiscal year. In the opinion of management, adjustments (which include only normal recurring adjustments) necessary for a fair statement of the consolidated results of the interim periods shown have been made.
Inventory	Inventories, net are valued at the lower of cost (first-in, first-out) or net realizable value.Inventories are recorded net of reserves for obsolete inventory (excess and slow-moving) of $106.6 million and $111.0 million at November 30, 2021 and May 31, 2021, respectively. The inventory obsolescence reserve is determined by specific identification, as well as an estimate based on Cintas' historical rates of obsolescence. Once a specific inventory item is written down to the lower of cost or net realizable value, a new cost basis has been established, and that inventory item cannot subsequently be marked up.
Reclassification of Prior Year Presentation	Certain prior year amounts have been reclassified for consistency with the current year presentation. The reclassification has been reflected in the consolidated condensed balance sheet and consolidated condensed statement of shareholders' equity for the fiscal year ended May 31, 2021 and the three and six months ended November 30, 2020, to combine common stock and paid-in capital for presentation purposes. These reclassifications had no effect on the Company's reported results of operations.
New Accounting Pronouncements	In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . ASU 2019-12 is part of the FASB’s overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. ASU 2019-12 removes certain exceptions to the general principles of Accounting Standards Codification (ASC) 740, Income Taxes (ASC 740), in order to reduce the cost and complexity of its application in the areas of intraperiod tax allocation, deferred tax liabilities related to outside basis differences, year-to-date losses in interim periods and other areas within ASC 740. The Company adopted ASU 2019-12 on June 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated condensed financial statements currently but may in future periods. No other new accounting pronouncement recently issued or newly effective had, or is expected to have, a material impact on Cintas' consolidated condensed financial statements.
