Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) or adopted by the Company during the nine months ended October 31, 2020, that are applicable to the Company. Accounting standards adopted In June 2016, FASB issued ASU No. 2016-13 regarding ASC Topic 326, “Financial Instruments - Credit Losses,” which requires the measurement and recognition of expected credit losses for certain financial instruments using forward-looking information to calculate credit loss estimates. Autodesk adopted ASU 2016-13 as of the effective date which represents Autodesk’s fiscal year beginning February 1, 2020. The ASU did not have a material impact on Autodesk's consolidated financial statements at adoption. Adoption and policy elections Allowances for uncollectible trade receivables and contract assets are subject to impairment using the expected credit loss model. Allowances for expected credit losses are measured based upon the lifetime expected credit loss which is based on historical experience, the number of days that billings are past due, reasonable economic forecast, including revised forecast data for the current economic environment, customer payment behavior, credit reports and other customer specific information. Allowances for credit losses on trade receivables and contract assets were not material as of October 31, 2020. Autodesk’s investments in available-for-sale debt securities are subject to a periodic impairment review. If Autodesk does not intend to sell and it is more likely than not that Autodesk will not be required to sell the available-for-sale debt security prior to recovery of its amortized cost basis, Autodesk will determine whether a decline in fair value below the amortized cost basis is due to credit-related factors. The credit loss is measured as the amount by which the debt security’s amortized cost basis exceeds the estimate of the present value of cash flows expected to be collected, up to the difference between the amortized cost basis and the fair value. Impairment will be assessed at the individual security level. Credit-related impairment is recognized as an allowance on the Condensed Consolidated Balance Sheets with a corresponding adjustment to “Interest and other expense, net” on the Company's Condensed Consolidated Statements of Operations. Any impairment that is not credit-related is recognized in “Accumulated other comprehensive loss” on the Condensed Consolidated Balance Sheets. Autodesk does not measure an allowance for credit losses on accrued interest receivables on available-for-sale debt securities separately. Autodesk writes off accrued interest receivables by reversing interest income in the period deemed uncollectible in “Interest and other expense, net” on the Company's Condensed Consolidated Statements of Operations. Any accrued interest receivable on available-for-sale debt securities is recorded in “Cash and cash equivalents”, “Prepaid expenses and other current assets,” or “Long-term other assets,” in the accompanying Condensed Consolidated Balance Sheets, as applicable. Recently issued accounting standards not yet adopted In March 2020, FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU No. 2020-04"), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Autodesk will apply the expedients in ASU No. 2020-04 through December 31, 2022. Autodesk does not believe ASU No. 2020-04 will have a material impact on its consolidated financial statements.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Revenue Disaggregation Autodesk recognizes revenue from the sale of (1) product subscriptions, cloud service offerings, and enterprise business agreements (“EBAs”), (2) renewal fees for existing maintenance plan agreements that were initially purchased with a perpetual software license, and (3) consulting, training, and other goods and services. The three categories are presented as line items on Autodesk's Condensed Consolidated Statements of Operations. Information regarding the components of Autodesk's net revenue from contracts with customers by product family, geographic location, sales channel, and product type is as follows: Three Months Ended October 31, Nine Months Ended October 31, (in millions) 2020 2019 2020 2019 Net revenue by product family: Architecture, Engineering and Construction $ 419.4 $ 358.0 $ 1,199.1 $ 996.5 AutoCAD and AutoCAD LT 278.8 245.4 812.9 689.9 Manufacturing 194.1 182.2 562.5 524.3 Media and Entertainment 54.0 50.6 159.9 146.9 Other 6.1 6.5 16.8 17.4 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by geographic area: Americas U.S. $ 328.5 $ 287.3 $ 938.6 $ 804.3 Other Americas 64.4 62.0 188.0 166.7 Total Americas 392.9 349.3 1,126.6 971.0 Europe, Middle East and Africa 364.3 329.6 1,063.8 943.0 Asia Pacific 195.2 163.8 560.8 461.0 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by sales channel: Indirect $ 656.2 $ 586.6 $ 1,918.9 $ 1,663.2 Direct 296.2 256.1 832.3 711.8 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by product type: Design $ 847.7 $ 748.3 $ 2,466.8 $ 2,126.4 Make 76.5 57.9 214.9 154.8 Other 28.2 36.5 69.5 93.8 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Payments for product subscriptions, industry collections, cloud subscriptions, and maintenance subscriptions are typically due up front with payment terms of 30 to 45 days. As a result of the COVID-19 pandemic, we extended contract payment terms to 60 days through August 7, 2020, for all customers and partners for new orders and renewals placed directly with Autodesk. Payments on EBAs are typically due in annual installments over the contract term, with payment terms of 30 to 60 days. Autodesk does not have any material variable consideration, such as obligations for returns, refunds, warranties, or amounts due to customers for which significant estimation or judgment is required as of the reporting date. Remaining performance obligations consist of total short-term, long-term, and unbilled deferred revenue. As of October 31, 2020, Autodesk had remaining performance obligations of $3.58 billion, which represents the total contract price allocated to remaining performance obligations, which are generally recognized over the next three years. We expect to recognize $2.38 billion or 67% of our remaining performance obligations as revenue during the next 12 months. We expect to recognize the remaining $1.20 billion or 33% of our remaining performance obligations as revenue thereafter. The amount of remaining performance obligations may be impacted by the specific timing, duration, and size of customer subscription and support agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. Contract Balances We receive payments from customers based on a billing schedule as established in our contracts. Contract assets relate to performance completed in advance of scheduled billings. Contract assets were not material as of October 31, 2020. Deferred revenue relates to billings in advance of performance under the contract. The primary changes in our contract assets and deferred revenues are due to our performance under the contracts and billings. Revenue recognized during the three months ended October 31, 2020 and 2019, that was included in the deferred revenue balances at January 31, 2020 and 2019, was $481.9 million and $398.5 million, respectively. Revenue recognized during the nine months ended October 31, 2020 and 2019, that was included in the deferred revenue balances at January 31, 2020 and 2019, was $1.91 billion and $1.58 billion, respectively. The satisfaction of performance obligations typically lags behind payments received under revenue contracts from customers.

Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Concentration of Credit Risk Autodesk places its cash, cash equivalents, and marketable securities in highly liquid instruments with, and in the custody of, multiple diversified financial institutions globally with high credit ratings, and limits the amounts invested with any one institution, type of security, and issuer. Autodesk’s primary commercial banking relationship is with Citigroup Inc. and its global affiliates. Citibank, N.A., an affiliate of Citigroup, is one of the lead lenders and an agent in the syndicate of Autodesk’s $650.0 million line of credit facility. See Note 14, “Borrowing Arrangements,” in the Notes to Condensed Consolidated Financial Statements for further discussion. Total sales to the Company's largest distributor Tech Data Corporation and its global affiliates (“Tech Data”) accounted for 37% and 35% of Autodesk’s total net revenue for both the three and nine months ended October 31, 2020 and 2019, respectively. The majority of the net revenue from sales to Tech Data is for sales made outside of the United States. In addition, Tech Data accounted for 22% and 31% of trade accounts receivable at October 31, 2020, and January 31, 2020, respectively. Ingram Micro Inc. ("Ingram Micro") accounted for 10% of Autodesk's total net revenue during both the three and nine months ended October 31, 2020 and 2019. No other customer accounted for more than 10% of Autodesk's total net revenue or trade accounts receivable for each of the respective periods.

(5) Included in “Other accrued liabilities” in the accompanying Condensed Consolidated Balance Sheets. Autodesk applies fair value accounting for certain financial assets and liabilities, which consist of cash equivalents, marketable securities, and other financial instruments, on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As of both October 31, 2020, and January 31, 2020, Autodesk had no material unrealized losses, individually and in the aggregate, for marketable debt securities that are in a continuous unrealized loss position for greater than 12 months. Total unrealized gains for securities with net gains in accumulated other comprehensive income were not material for the nine months ended October 31, 2020. Autodesk monitors all marketable debt securities for potential credit losses by reviewing indicators such as current credit rating, change in credit rating, credit outlook, and default risk. There were no allowances for credit losses for the nine months ended October 31, 2020. There were no write offs of accrued interest receivables for the nine months ended October 31, 2020. There was no realized gain or loss for the sales or redemptions of debt securities during the nine months ended October 31, 2020 and 2019. Gains and losses resulting from the sale or redemption of debt securities are recorded in “Interest and other expense, net” on the Company's Condensed Consolidated Statements of Operations. There was $6.0 million and $17.0 million in proceeds from the sale and maturity of marketable debt securities for the three and nine months ended October 31, 2020, respectively. Autodesk did not have any proceeds from the sale and maturity of marketable securities for the three months ended October 31, 2019. Proceeds from the sale and maturity of marketable debt securities for the nine months ended October 31, 2019 was $27.4 million. As of October 31, 2020, Autodesk had non-marketable debt securities in privately held companies that had a fair value of $5.7 million. The amortized cost of these securities was $5.3 million and is classified as level 3 in the fair value hierarchy. There were no allowances for credit losses for the nine months ended October 31, 2020. Strategic investment equity securities As of October 31, 2020, and January 31, 2020, Autodesk had $134.8 million and $122.5 million in direct investments in privately held companies, respectively. These strategic investment equity securities do not have readily determined fair values, and Autodesk uses the measurement alternative to account for the adjustment to these investments in a given quarter. If Autodesk determines that an impairment has occurred, Autodesk writes down the investment to its fair value. Adjustments to the carrying value of our strategic investment equity securities with no readily determined fair values measured using the measurement alternative were as follows: Nine Months Ended October 31, Cumulative Amount as of (in millions) 2020 2019 October 31, 2020 Upward adjustments (1) $ 3.0 $ 2.5 $ 12.4 Negative adjustments, including impairments (1) (36.2) (4.3) (45.2) Net adjustments $ (33.2) $ (1.8) $ (32.8) ____________________ (1) Included in "Interest and other expense, net" on the Company's Condensed Consolidated Statements of Operations. Foreign currency contracts designated as cash flow hedges Autodesk uses foreign currency contracts to reduce the exchange rate impact on a portion of the net revenue or operating expense of certain anticipated transactions. These currency collars and forward contracts are designated and documented as cash flow hedges. The notional amounts of these contracts are presented net settled and were $1.36 billion at October 31, 2020, and $981.3 million at January 31, 2020. Outstanding contracts are recognized as either assets or liabilities on the Company's Condensed Consolidated Balance Sheet at fair value.

Share-based Payment Arrangement [Abstract]
Stock-based Compensation Expense	Stock-based Compensation Expense Restricted Stock Units: A summary of restricted stock activity for the nine months ended October 31, 2020, is as follows: Unvested Weighted (in thousands) Unvested restricted stock units at January 31, 2020 4,732.3 $ 147.24 Granted 2,215.0 217.27 Vested (1,976.4) 142.82 Canceled/Forfeited (166.1) 150.58 Performance Adjustment (1) 13.5 159.86 Unvested restricted stock units at October 31, 2020 4,818.3 $ 181.85 _______________ (1) Based on Autodesk's financial results and relative total stockholder return for the fiscal 2020 performance period. The performance stock units were attained at rates ranging from 96.6% to 101.1% of the target award. The fair value of the shares vested during the nine months ended October 31, 2020 and 2019, was $400.6 million and $277.3 million, respectively. During the nine months ended October 31, 2020, Autodesk granted 1.9 million restricted stock units. Autodesk recorded stock-based compensation expense related to restricted stock units of $74.7 million and $73.8 million during the three months ended October 31, 2020 and 2019, respectively. Autodesk recorded stock-based compensation expense related to restricted stock units of $222.9 million and $192.4 million during the nine months ended October 31, 2020 and 2019, respectively. During the nine months ended October 31, 2020, Autodesk settled liability-classified awards in the amount of $28.7 million. The ultimate number of shares earned was based on the Autodesk closing stock price on the vesting date. As these awards were settled in a fixed dollar amount of shares, the awards were accounted for as a liability-classified award and were expensed using the straight-line method over the vesting period. During the nine months ended October 31, 2020, Autodesk granted 0.3 million performance stock units for which the ultimate number of shares earned is determined based on the achievement of performance criteria at the end of the stated service and performance period. The performance criteria for the performance stock units are based on revenue goals adopted by the Compensation and Human Resource Committee and, as applicable, total stockholder return compared against companies in the S&P North American Technology Software Index with a market capitalization over $2.0 billion (“Relative TSR”). The fair value of the performance stock units is expensed using the accelerated attribution method over the three-year vesting period and have the following vesting schedule: • Up to one third of the performance stock units may vest following year one, depending upon the achievement of the performance criteria for fiscal 2021 as well as 1-year Relative TSR (covering year one). • Up to one third of the performance stock units may vest following year two, depending upon the achievement of the performance criteria for year two as well as 2-year Relative TSR (covering years one and two). • Up to one third of the performance stock units may vest following year three, depending upon the achievement of the performance criteria for year three as well as 3-year Relative TSR (covering years one, two and three). Performance stock units are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. Autodesk recorded stock-based compensation expense related to performance stock units of $8.7 million and $6.4 million for the three months ended October 31, 2020 and 2019, respectively. Autodesk recorded stock-based compensation expense related to performance stock units of $26.2 million and $18.6 million for the nine months ended October 31, 2020 and 2019, respectively. 1998 Employee Qualified Stock Purchase Plan (“ESPP”) Under Autodesk’s ESPP, which was approved by stockholders in 1998, eligible employees may purchase shares of Autodesk’s common stock at their discretion using up to 15% of their eligible compensation, subject to certain limitations, at 85% of the lower of Autodesk's closing price (fair market value) on the offering date or the exercise date. The offering period for ESPP awards consists of four, six-month exercise periods within a 24-month offering period. A summary of the ESPP activity for the three and nine months ended October 31, 2020 and 2019, is as follows: Three Months Ended October 31, Nine Months Ended October 31, 2020 2019 2020 2019 Issued shares (in millions) 0.4 0.4 0.9 0.9 Average price of issued shares $ 122.93 $ 105.42 $ 122.73 $ 102.20 Weighted average grant date fair value of shares granted under the ESPP (1) $ 78.26 $ 44.77 $ 55.98 $ 47.78 _______________ (1) Calculated as of the award grant date using the Black-Scholes Merton (“BSM”) option pricing model. Stock-based Compensation Expense The following table summarizes stock-based compensation expense for the three and nine months ended October 31, 2020 and 2019, respectively, as follows: Three Months Ended October 31, Nine Months Ended October 31, (in millions) 2020 2019 2020 2019 Cost of subscription and maintenance revenue $ 4.5 $ 3.1 $ 12.3 $ 10.1 Cost of other revenue 1.6 1.6 4.7 4.3 Marketing and sales 45.4 38.7 129.5 107.2 Research and development 35.4 30.8 103.6 88.3 General and administrative 10.5 19.8 41.4 47.5 Stock-based compensation expense related to stock awards and ESPP purchases 97.4 94.0 291.5 257.4 Tax benefit (2.0) (0.5) (2.3) (0.8) Stock-based compensation expense related to stock awards and ESPP purchases, net of tax $ 95.4 $ 93.5 $ 289.2 $ 256.6 Stock-based Compensation Expense Assumptions Autodesk determines the grant date fair value of its share-based payment awards using a BSM option pricing model or the quoted stock price on the date of grant, unless the awards are subject to market conditions, in which case Autodesk uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model uses multiple input variables to estimate the probability that market conditions will be achieved. Autodesk uses the following assumptions to estimate the fair value of stock-based awards: Three Months Ended October 31, 2020 Three Months Ended October 31, 2019 Performance Stock Units ESPP Performance Stock Units ESPP Range of expected volatilities N/A 41.5 - 45.0% N/A 32.7 - 35.9% Range of expected lives (in years) N/A 0.5 - 2.0 N/A 0.5 - 2.0 Expected dividends N/A — N/A — Range of risk-free interest rates N/A 0.1% N/A 1.7 - 1.9% Nine Months Ended October 31, 2020 Nine Months Ended October 31, 2019 Performance Stock Units ESPP Performance Stock Units ESPP Range of expected volatilities 50.7% 39.4 - 45.8% 36.3% 32.7 - 39.7% Range of expected lives (in years) N/A 0.5 - 2.0 N/A 0.5 - 2.0 Expected dividends —% —% —% —% Range of risk-free interest rates 0.3% 0.1 - 0.5% 2.5% 1.7 - 2.5% Autodesk estimates expected volatility for stock-based awards based on the average of the following two measures: (1) a measure of historical volatility in the trading market for the Company’s common stock, and (2) the implied volatility of traded forward call options to purchase shares of the Company’s common stock. The expected volatility for performance stock units subject to market conditions includes the expected volatility of Autodesk's peer companies within the S&P North American Technology Software Index with a market capitalization over $2.0 billion, depending on the award type. The range of expected lives of ESPP awards are based upon the four, six-month exercise periods within a 24-month offering period. Autodesk does not currently pay, and does not anticipate paying in the foreseeable future, any cash dividends. Consequently, an expected dividend yield of zero is used in the BSM option pricing model and the Monte Carlo simulation model. The risk-free interest rate used in the BSM option pricing model and the Monte Carlo simulation model for stock-based awards is the historical yield on U.S. Treasury securities with equivalent remaining lives. Autodesk recognizes expense only for the stock-based awards that ultimately vest. Autodesk accounts for forfeitures of our stock-based awards as those forfeitures occur.

Income Tax

Income Tax Disclosure [Abstract]
Income Tax	Income Tax Autodesk had income tax expense of $23.9 million, relative to pre-tax income of $156.1 million for the three months ended October 31, 2020, and income tax expense of $29.7 million, relative to pre-tax income of $96.4 million for the three months ended October 31, 2019. Autodesk had income tax expense of $78.7 million, relative to pre-tax income of $375.6 million for the nine months ended October 31, 2020, and income tax expense of $88.8 million, relative to pre-tax income of $171.5 million for the nine months ended October 31, 2019. Income tax expense for the three and nine months ended October 31, 2020, decreased as a result of the jurisdictional mix of year-to-date earnings relative to the worldwide annual effective tax rate. Autodesk regularly assesses the need for a valuation allowance against its deferred tax assets. In making that assessment, Autodesk considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more likely than not that some or all of the deferred tax assets will not be realized. The Company anticipates a significant increase in U.S. taxable income in fiscal 2021 due to forecasted global earnings. We currently forecast the utilization of U.S. deferred tax assets to offset U.S. taxable income resulting from the inclusion of foreign earnings. While increased U.S. taxable income is considered positive evidence, the uncertainties around the global economy arising from COVID-19 and our cumulative losses outweigh that positive evidence. Accordingly, we have maintained the valuation allowance on our U.S. deferred tax assets. As of October 31, 2020, the Company had $221.3 million of gross unrecognized tax benefits, of which $203.7 million would reduce our valuation allowance, if recognized. The remaining $17.7 million would impact the effective tax rate, if recognized. It is possible that the amount of unrecognized tax benefits will change in the next 12 months; however, an estimate of the range of the possible change cannot be made at this time.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions During the three and nine months ended October 31, 2020, Autodesk completed two business combinations. The acquisition-date fair value of the cash consideration transferred totaled $45.4 million. The results of operations for these acquisitions were included in the accompanying Condensed Consolidated Statement of Operations from the dates of the respective acquisitions. Pro forma results of operations have not been presented because the effects of these acquisitions were not material to Autodesk's Condensed Consolidated Financial Statements. The acquisitions were accounted for as business combinations, and Autodesk recorded the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. Autodesk recorded the excess of consideration transferred over the aggregate fair values as goodwill. The goodwill recorded was primarily attributable to synergies expected to arise after the acquisition. There is no amount of goodwill that is deductible for U.S. income tax purposes. The following table summarizes the fair value of the assets acquired and liabilities assumed by major class for the business combinations that were completed during the three and nine months ended October 31, 2020: (in millions) Aggregate Total Developed technologies $ 12.0 Customer relationships 5.7 Trade name 0.8 Goodwill 31.4 Deferred revenue and long-term deferred revenue (2.2) Net tangible liabilities (2.3) Total $ 45.4 For the business combinations, the allocation of purchase price consideration to certain assets and liabilities is not yet finalized. For the items not yet finalized, Autodesk's estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date).

Cloud Computing Arrangements	Revenue Recognition Revenue Disaggregation Autodesk recognizes revenue from the sale of (1) product subscriptions, cloud service offerings, and enterprise business agreements (“EBAs”), (2) renewal fees for existing maintenance plan agreements that were initially purchased with a perpetual software license, and (3) consulting, training, and other goods and services. The three categories are presented as line items on Autodesk's Condensed Consolidated Statements of Operations. Information regarding the components of Autodesk's net revenue from contracts with customers by product family, geographic location, sales channel, and product type is as follows: Three Months Ended October 31, Nine Months Ended October 31, (in millions) 2020 2019 2020 2019 Net revenue by product family: Architecture, Engineering and Construction $ 419.4 $ 358.0 $ 1,199.1 $ 996.5 AutoCAD and AutoCAD LT 278.8 245.4 812.9 689.9 Manufacturing 194.1 182.2 562.5 524.3 Media and Entertainment 54.0 50.6 159.9 146.9 Other 6.1 6.5 16.8 17.4 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by geographic area: Americas U.S. $ 328.5 $ 287.3 $ 938.6 $ 804.3 Other Americas 64.4 62.0 188.0 166.7 Total Americas 392.9 349.3 1,126.6 971.0 Europe, Middle East and Africa 364.3 329.6 1,063.8 943.0 Asia Pacific 195.2 163.8 560.8 461.0 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by sales channel: Indirect $ 656.2 $ 586.6 $ 1,918.9 $ 1,663.2 Direct 296.2 256.1 832.3 711.8 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Net revenue by product type: Design $ 847.7 $ 748.3 $ 2,466.8 $ 2,126.4 Make 76.5 57.9 214.9 154.8 Other 28.2 36.5 69.5 93.8 Total net revenue $ 952.4 $ 842.7 $ 2,751.2 $ 2,375.0 Payments for product subscriptions, industry collections, cloud subscriptions, and maintenance subscriptions are typically due up front with payment terms of 30 to 45 days. As a result of the COVID-19 pandemic, we extended contract payment terms to 60 days through August 7, 2020, for all customers and partners for new orders and renewals placed directly with Autodesk. Payments on EBAs are typically due in annual installments over the contract term, with payment terms of 30 to 60 days. Autodesk does not have any material variable consideration, such as obligations for returns, refunds, warranties, or amounts due to customers for which significant estimation or judgment is required as of the reporting date. Remaining performance obligations consist of total short-term, long-term, and unbilled deferred revenue. As of October 31, 2020, Autodesk had remaining performance obligations of $3.58 billion, which represents the total contract price allocated to remaining performance obligations, which are generally recognized over the next three years. We expect to recognize $2.38 billion or 67% of our remaining performance obligations as revenue during the next 12 months. We expect to recognize the remaining $1.20 billion or 33% of our remaining performance obligations as revenue thereafter. The amount of remaining performance obligations may be impacted by the specific timing, duration, and size of customer subscription and support agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. Contract Balances We receive payments from customers based on a billing schedule as established in our contracts. Contract assets relate to performance completed in advance of scheduled billings. Contract assets were not material as of October 31, 2020. Deferred revenue relates to billings in advance of performance under the contract. The primary changes in our contract assets and deferred revenues are due to our performance under the contracts and billings. Revenue recognized during the three months ended October 31, 2020 and 2019, that was included in the deferred revenue balances at January 31, 2020 and 2019, was $481.9 million and $398.5 million, respectively. Revenue recognized during the nine months ended October 31, 2020 and 2019, that was included in the deferred revenue balances at January 31, 2020 and 2019, was $1.91 billion and $1.58 billion, respectively. The satisfaction of performance obligations typically lags behind payments received under revenue contracts from customers.

Goodwill

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill consists of the excess of the consideration transferred over the fair value of net assets acquired in business combinations. The following table summarizes the changes in the carrying amount of goodwill for the nine months ended October 31, 2020 (in millions): Balance as of January 31, 2020 $ 2,594.2 Less: accumulated impairment losses as of January 31, 2020 (149.2) Net balance as of January 31, 2020 2,445.0 Additions arising from acquisitions during the period 31.4 Effect of foreign currency translation 7.8 Balance as of October 31, 2020 $ 2,484.2 Autodesk operates as a single operating segment and single reporting unit. As such, when Autodesk tests goodwill for impairment annually in its fourth fiscal quarter, it is performed on the Company's single reporting unit. Autodesk performs impairment testing more often if circumstances indicate a potential impairment may exist, or if events have affected the composition of reporting units. When goodwill is assessed for impairment, Autodesk has the option to perform an assessment of qualitative factors of impairment (“optional assessment”) prior to necessitating a quantitative impairment test. Should the optional assessment be used for any given fiscal year, qualitative factors to consider include cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations, macroeconomic conditions, and other relevant events and factors affecting the reporting unit. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the quantitative impairment test is unnecessary. The quantitative impairment test is necessary when either Autodesk does not use the optional assessment or, as a result of the optional assessment, it is not more likely than not that the fair value of the reporting unit is greater than its carrying value. In situations in which an entity’s reporting unit is publicly traded, the fair value of the Company may be approximated by its market capitalization in performing the quantitative impairment test. Goodwill impairment exists when the estimated fair value of goodwill is less than its carrying value. If impairment exists, the carrying value of the goodwill is reduced to fair value through an impairment charge recorded in our Condensed Consolidated Statements of Operations. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. The value of Autodesk’s goodwill could also be impacted by future adverse changes such as: (i) declines in Autodesk’s actual financial results, (ii) a sustained decline in Autodesk’s market capitalization, (iii) a significant slowdown in the worldwide economy or the industries Autodesk serves, or (iv) changes in Autodesk’s business strategy. There was no goodwill impairment during the three and nine months ended October 31, 2020.

Debt Disclosure [Abstract]
Borrowing Arrangements	Borrowing Arrangements In January 2020, Autodesk issued $500.0 million aggregate principal amount of 2.85% notes due January 15, 2030 (“2020 Notes”). Net of a discount of $1.1 million and issuance costs of $4.8 million, Autodesk received net proceeds of $494.1 million from issuance of the 2020 Notes. Both the discount and issuance costs are being amortized to interest expense over the term of the 2020 Notes using the effective interest method. The proceeds of the 2020 Notes have been used for the repayment of the $450.0 million 2015 Notes, as defined below, and the remainder is available for general corporate purposes. In December 2018, Autodesk entered into a credit agreement by and among Autodesk, the lenders from time to time party thereto, and Citibank, N.A., as agent, which provides for an unsecured revolving loan facility in the aggregate principal amount of $650.0 million with an option, subject to customary conditions, to request an increase in the amount of the credit facility by up to an additional $350.0 million, and is available for working capital or other business needs. The credit agreement contains customary covenants that could, among other things, restrict the imposition of liens on Autodesk’s assets, and restrict Autodesk’s ability to incur additional indebtedness or make dispositions of assets if Autodesk fails to maintain compliance with the financial covenants. The credit agreement financial covenants consist of (1) a minimum interest coverage ratio of 2.50:1.0 starting with the fiscal quarter ending January 31, 2019, and increasing to 3.00:1.0 starting with the fiscal quarter ending April 30, 2019, and (2) a maximum leverage ratio of 3.50:1.0 starting with the fiscal quarter ending July 31, 2019, and dropping to 3.00:1.0 in the fiscal quarter ending January 31, 2020. At October 31, 2020, Autodesk was in compliance with the credit agreement covenants. Revolving loans under the credit agreement bear interest, at Autodesk’s option, at either (i) a floating rate per annum equal to the base rate plus a margin of between 0.000% and 0.500%, depending on Autodesk’s Public Debt Rating (as defined in the credit agreement) or (ii) a per annum rate equal to the rate at which dollar deposits are offered in the London interbank market, plus a margin of between 0.900% and 1.500%, depending on Autodesk’s Public Debt Rating. The maturity date on the credit agreement is December 2023. At October 31, 2020, Autodesk had no outstanding borrowings under the credit agreement. In June 2017, Autodesk issued $500.0 million aggregate principal amount of 3.5% notes due June 15, 2027 (the “2017 Notes”). Net of a discount of $3.1 million and issuance costs of $4.9 million, Autodesk received net proceeds of $492.0 million from issuance of the 2017 Notes. Both the discount and issuance costs are being amortized to interest expense over the term of the 2017 Notes using the effective interest method. The proceeds of the 2017 Notes have been used for the repayment of $400.0 million of debt due December 15, 2017, and the remainder is available for general corporate purposes. In June 2015, Autodesk issued $450.0 million aggregate principal amount of 3.125% notes due June 15, 2020 (“$450.0 million 2015 Notes”) and $300.0 million aggregate principal amount of 4.375% notes due June 15, 2025 (“$300.0 million 2015 Notes”) (collectively, the “2015 Notes”). Net of a discount of $0.6 million and $1.1 million, and issuance costs of $3.8 million and $2.5 million, Autodesk received net proceeds of $445.6 million and $296.4 million from issuance of the $450.0 million 2015 Notes and $300.0 million 2015 Notes, respectively. Both the discount and issuance costs are being amortized to interest expense over the respective term of the $300.0 million 2015 Notes using the effective interest method. The proceeds of the $300.0 million 2015 Notes is available for general corporate purposes. On March 4, 2020, the proceeds of the 2020 Notes were used for the repayment of the $450.0 million 2015 Notes. Autodesk paid a redemption price of $452.1 million, plus accrued and unpaid interest to, but not including, the date of redemption. In December 2012, Autodesk issued $350.0 million aggregate principal amount of 3.6% notes due December 15, 2022 (“2012 Notes”). Autodesk received net proceeds of $346.7 million from issuance of the 2012 Notes, net of a discount of $0.5 million and issuance costs of $2.8 million. Both the discount and issuance costs are being amortized to interest expense over the respective terms of the 2012 Notes using the effective interest method. The proceeds of the 2012 Notes are available for general corporate purposes. The 2020 Notes, 2017 Notes, $300 million 2015 Notes and the 2012 Notes may all be redeemed at any time, subject to a make whole premium. In addition, upon the occurrence of certain change of control triggering events, Autodesk may be required to repurchase all the aforementioned notes, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase. All notes contain restrictive covenants that limit Autodesk's ability to create certain liens, to enter into certain sale and leaseback transactions and to consolidate or merge with, or convey, transfer, or lease all or substantially all of its assets, subject to important qualifications and exceptions. Based on the quoted market prices, the approximate fair value of the notes as of October 31, 2020, were as follows: (in millions) Aggregate Principal Amount Fair value 2012 Notes $ 350.0 $ 369.1 $300 million 2015 Notes 300.0 340.5 2017 Notes 500.0 562.2 2020 Notes 500.0 550.4 The expected future principal payments for all borrowings as of October 31, 2020, is as follows (in millions): Fiscal year ending 2021 (remainder) $ — 2022 — 2023 350.0 2024 — 2025 — Thereafter 1,300.0 Total principal outstanding $ 1,650.0

Leases [Abstract]
Leases	Leases Autodesk has operating leases for real estate, vehicles, and certain equipment. Leases have remaining lease terms of less than 1 year to 70 years, some of which include options to extend the lease with renewal terms from 1 year to 10 years and some of which include options to terminate the leases from less than 1 year to 10 years. Options to extend the lease are included in the lease liability if they are reasonably certain of being exercised. Payments under our lease arrangements are primarily fixed; however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the operating lease assets and liabilities. These amounts include payments affected by the Consumer Price Index, payments for common area maintenance that are subject to annual reconciliation, and payments for maintenance and utilities. The Company’s leases do not contain residual value guarantees or material restrictive covenants. Short-term leases are recognized in the Condensed Consolidated Statements of Operations on a straight-line basis over the lease term. Short-term lease expense was not material for the periods presented. Changes in operating lease right-of-use assets and operating lease liabilities are presented net in the “accounts payable and other liabilities” line in the Condensed Consolidated Statements of Cash Flows. The components of lease cost were as follows: Three Months Ended October 31, 2020 (in millions) Cost of subscription and maintenance revenue Cost of other revenue Marketing and sales Research and development General and administrative Total Operating lease cost $ 1.9 $ 0.6 $ 11.9 $ 8.6 $ 2.9 $ 25.9 Variable lease cost 0.2 0.1 1.5 1.0 0.4 3.2 Nine Months Ended October 31, 2020 (in millions) Cost of subscription and maintenance revenue Cost of other revenue Marketing and sales Research and development General and administrative Total Operating lease cost $ 5.6 $ 1.7 $ 34.0 $ 24.3 $ 10.5 $ 76.1 Variable lease cost 0.6 0.2 4.0 2.8 1.3 8.9 Three Months Ended October 31, 2019 (in millions) Cost of subscription and maintenance revenue Cost of other revenue Marketing and sales Research and development General and administrative Total Operating lease cost $ 1.7 $ 0.6 $ 9.6 $ 6.6 $ 3.2 $ 21.7 Variable lease cost 0.2 0.1 1.1 0.7 0.4 2.5 Nine Months Ended October 31, 2019 (in millions) Cost of subscription and maintenance revenue Cost of other revenue Marketing and sales Research and development General and administrative Total Operating lease cost $ 4.9 $ 1.7 $ 28.0 $ 20.1 $ 9.0 $ 63.7 Variable lease cost 0.7 0.2 3.9 2.8 1.3 8.9 Supplemental operating cash flow information related to leases is as follows: Nine Months Ended October 31, (in millions) 2020 2019 Cash paid for operating leases included in operating cash flows (1) $ 74.7 $ 66.4 Non-cash operating lease liabilities arising from obtaining operating lease right-of-use assets $ 50.8 $ 55.2 _______________ (1) Includes $8.9 million in variable lease payments for both the nine months ended October 31, 2020 and 2019, not included in “Operating lease liabilities” and “Long-term operating lease liabilities” on the Condensed Consolidated Balance Sheets. The weighted average remaining lease term for operating leases is 7.3 and 7.5 years at October 31, 2020, and January 31, 2020, respectively. The weighted average discount rate was 2.79% and 3.41% at October 31, 2020, and January 31, 2020, respectively. Maturities of operating lease liabilities were as follows (in millions): Fiscal year ending 2021 (remainder) $ 12.9 2022 87.5 2023 91.9 2024 76.6 2025 57.0 Thereafter 182.2 508.1 Less imputed interest (45.8) Present value of operating lease liabilities $ 462.3

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Guarantees and Indemnifications In the normal course of business, Autodesk provides indemnifications of varying scopes, including limited product warranties and indemnification of customers against claims of intellectual property infringement made by third parties arising from the use of its products or services. Autodesk accrues for known indemnification issues if a loss is probable and can be reasonably estimated. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations. In connection with the purchase, sale, or license of assets or businesses with third parties, Autodesk has entered into or assumed customary indemnification agreements related to the assets or businesses purchased, sold, or licensed. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations. As permitted under Delaware law, Autodesk has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at Autodesk’s request in such capacity. The maximum potential amount of future payments Autodesk could be required to make under these indemnification agreements is unlimited; however, Autodesk has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable Autodesk to recover a portion of any future amounts paid. Autodesk believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal. Legal Proceedings Autodesk is involved in a variety of claims, suits, investigations, inquiries, and proceedings in the normal course of business including claims of alleged infringement of intellectual property rights, commercial, employment, tax, prosecution of unauthorized use, business practices, and other matters. Autodesk routinely reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any matter is considered probable and the amount can be reasonably estimated, Autodesk records a liability for the estimated loss. Because of inherent uncertainties related to these legal matters, Autodesk bases its loss accruals on the best information available at the time. As additional information becomes available, Autodesk reassesses its potential liability and may revise its estimates. In the Company's opinion, resolution of pending matters is not expected to have a material adverse impact on its consolidated results of operations, cash flows, or its financial position. Given the unpredictable nature of legal proceedings, there is a reasonable possibility that an unfavorable resolution of one or more such proceedings could in the future materially affect the Company's results of operations, cash flows, or financial position in a particular period, however, based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company's financial statements, any such amount is either immaterial or it is not possible to provide an estimated amount of any such potential loss.

Segment Reporting [Abstract]
Segments	Segments Autodesk operates in one operating segment and accordingly, all required financial segment information is included in the condensed consolidated financial statements. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision makers (“CODM”) in deciding how to allocate resources and assess performance. Autodesk reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions, allocating resources and assessing performance as the source of the Company’s reportable segments. The Company’s CODM allocates resources and assesses the operating performance of the Company as a whole.

Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	The accompanying unaudited Condensed Consolidated Financial Statements of Autodesk, Inc. (“Autodesk,” “we,” “us,” “our,” or the “Company”) as of October 31, 2020, and for the three and nine months ended October 31, 2020 and 2019, have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information along with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In management’s opinion, Autodesk made all adjustments (consisting of normal, recurring and non-recurring adjustments) during the quarter that were considered necessary for the fair statement of the financial position and operating results of the Company. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. In March 2020, the World Health Organization declared the outbreak of a disease caused by a novel strain of the coronavirus (COVID-19) to be a pandemic. This pandemic has created and may continue to create significant uncertainty in the macroeconomic environment which, in addition to other unforeseen effects of this pandemic, may adversely impact our results of operations. As the COVID-19 pandemic continues to develop, many of our estimates could require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve our estimates may change materially in future periods. In addition, the results of operations for the three and nine months ended October 31, 2020, are not necessarily indicative of the results for the entire fiscal year ending January 31, 2021, or for any other period. Further, the balance sheet as of January 31, 2020, has been derived from the audited Consolidated Balance Sheet as of this date. There have been no material changes, other than what is discussed herein, to Autodesk's significant accounting policies as compared to the significant accounting policies disclosed in the Annual Report on Form 10-K for the fiscal year ended January 31, 2020. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes, together with management’s discussion and analysis of financial position and results of operations, contained in Autodesk’s Annual Report on Form 10-K for the fiscal year ended January 31, 2020, filed on March 19, 2020.
Recently Issued Accounting Standards	Accounting standards adopted In June 2016, FASB issued ASU No. 2016-13 regarding ASC Topic 326, “Financial Instruments - Credit Losses,” which requires the measurement and recognition of expected credit losses for certain financial instruments using forward-looking information to calculate credit loss estimates. Autodesk adopted ASU 2016-13 as of the effective date which represents Autodesk’s fiscal year beginning February 1, 2020. The ASU did not have a material impact on Autodesk's consolidated financial statements at adoption. Adoption and policy elections Allowances for uncollectible trade receivables and contract assets are subject to impairment using the expected credit loss model. Allowances for expected credit losses are measured based upon the lifetime expected credit loss which is based on historical experience, the number of days that billings are past due, reasonable economic forecast, including revised forecast data for the current economic environment, customer payment behavior, credit reports and other customer specific information. Allowances for credit losses on trade receivables and contract assets were not material as of October 31, 2020. Autodesk’s investments in available-for-sale debt securities are subject to a periodic impairment review. If Autodesk does not intend to sell and it is more likely than not that Autodesk will not be required to sell the available-for-sale debt security prior to recovery of its amortized cost basis, Autodesk will determine whether a decline in fair value below the amortized cost basis is due to credit-related factors. The credit loss is measured as the amount by which the debt security’s amortized cost basis exceeds the estimate of the present value of cash flows expected to be collected, up to the difference between the amortized cost basis and the fair value. Impairment will be assessed at the individual security level. Credit-related impairment is recognized as an allowance on the Condensed Consolidated Balance Sheets with a corresponding adjustment to “Interest and other expense, net” on the Company's Condensed Consolidated Statements of Operations. Any impairment that is not credit-related is recognized in “Accumulated other comprehensive loss” on the Condensed Consolidated Balance Sheets. Autodesk does not measure an allowance for credit losses on accrued interest receivables on available-for-sale debt securities separately. Autodesk writes off accrued interest receivables by reversing interest income in the period deemed uncollectible in “Interest and other expense, net” on the Company's Condensed Consolidated Statements of Operations. Any accrued interest receivable on available-for-sale debt securities is recorded in “Cash and cash equivalents”, “Prepaid expenses and other current assets,” or “Long-term other assets,” in the accompanying Condensed Consolidated Balance Sheets, as applicable. Recently issued accounting standards not yet adopted In March 2020, FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU No. 2020-04"), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Autodesk will apply the expedients in ASU No. 2020-04 through December 31, 2022. Autodesk does not believe ASU No. 2020-04 will have a material impact on its consolidated financial statements.
Revenue Recognition	Revenue DisaggregationAutodesk recognizes revenue from the sale of (1) product subscriptions, cloud service offerings, and enterprise business agreements (“EBAs”), (2) renewal fees for existing maintenance plan agreements that were initially purchased with a perpetual software license, and (3) consulting, training, and other goods and services. The three categories are presented as line items on Autodesk's Condensed Consolidated Statements of Operations.
Fair Value Measurement	Autodesk applies fair value accounting for certain financial assets and liabilities, which consist of cash equivalents, marketable securities, and other financial instruments, on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
