Accounting Policies [Abstract]
Nature of Business	Nature of Business Fair Isaac Corporation Incorporated under the laws of the State of Delaware, Fair Isaac Corporation (“FICO”) is a provider of analytic, software and data management products and services that enable businesses to automate, improve and connect decisions. FICO provides a range of analytic solutions, credit scoring and credit account management products and services to banks, credit reporting agencies, credit card processing agencies, insurers, retailers, healthcare organizations and public agencies. In this Quarterly Report on Form 10-Q, Fair Isaac Corporation is referred to as “FICO,” “we,” “us,” “our,” or “the Company.” Principles of Consolidation and Basis of Presentation We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the applicable accounting guidance. Consequently, we have not necessarily included all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our financial position and results of operations. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our audited consolidated financial statements and notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. The interim financial information contained in this report is not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year. The condensed consolidated financial statements include the accounts of FICO and its subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates We make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the collectibility of accounts receivable; the appropriate levels of various accruals; variable considerations included in the transaction price for our customer contracts; labor hours in connection with fixed-fee service contracts; the amount of our tax provision; and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units and share-based compensation. Actual results may differ from our estimates. As the impact of the COVID-19 pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the condensed consolidated financial statements as new events occur and additional information becomes known. To the extent our actual results differ materially from those estimates and assumptions, our future financial statements could be affected. For more information, see Part II, Item 1A “Risk Factors” of this Quarterly Report on Form 10-Q. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-15, Intangibles—Goodwill and Other (Topic 350): Internal-Use Software (“ASU 2018-15”). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted ASU 2018-15 in the first quarter of our fiscal 2021 and the adoption did not have a significant impact on our condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04, ASU 2019-05 and ASU 2019-11 (collectively, “Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted Topic 326 in the first quarter of our fiscal 2021 and the adoption did not have a significant impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted We do not expect that any recently issued accounting pronouncements will have a significant effect on our financial statements.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance establishes a three-level hierarchy for disclosure that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. • Level 1 - uses unadjusted quoted prices that are available in active markets for identical assets or liabilities. Our Level 1 assets are comprised of money market funds and certain marketable securities. We did not have any liabilities that are valued using inputs identified under a Level 1 hierarchy as of March 31, 2021 and September 30, 2020. • Level 2 - uses inputs other than quoted prices included in Level 1 that are either directly or indirectly observable through correlation with market data. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data. We did not have any assets that are valued using inputs identified under a Level 2 hierarchy as of March 31, 2021 and September 30, 2020. We measure the fair value of our senior notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. • Level 3 - uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, and significant management judgment or estimation. We did not have any assets or liabilities that are valued using inputs identified under a Level 3 hierarchy as of March 31, 2021 and September 30, 2020. The following tables represent financial assets that we measured at fair value on a recurring basis at March 31, 2021 and September 30, 2020: March 31, 2021 Active Markets for Fair Value as of March 31, 2021 (In thousands) Assets: Cash equivalents (1) $ 194 $ 194 Marketable securities (2) 30,437 30,437 Total $ 30,631 $ 30,631 September 30, 2020 Active Markets for Fair Value as of September 30, 2020 (In thousands) Assets: Cash equivalents (1) $ 35,275 $ 35,275 Marketable securities (2) 25,513 25,513 Total $ 60,788 $ 60,788 (1) Included in cash and cash equivalents on our condensed consolidated balance sheets at March 31, 2021 and September 30, 2020. Not included in these tables are cash deposits of $197.6 million and $122.1 million at March 31, 2021 and September 30, 2020, respectively. (2) Represents securities held under a supplemental retirement and savings plan for senior management employees, which are distributed upon termination or retirement of the employees. Included in marketable securities on our condensed consolidated balance sheets at March 31, 2021 and September 30, 2020. See Note 7 for the fair value of our senior notes. There were no transfers between Level 1, Level 2, and Level 3 of the fair value hierarchy during the quarters and six-month periods ended March 31, 2021 and 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We use derivative instruments to manage risks caused by fluctuations in foreign exchange rates. The primary objective of our derivative instruments is to protect the value of foreign-currency-denominated receivable and cash balances from the effects of volatility in foreign exchange rates that might occur prior to conversion to their respective functional currencies. We principally utilize foreign currency forward contracts, which enable us to buy and sell foreign currencies in the future at fixed exchange rates and economically offset changes in foreign exchange rates. We routinely enter into contracts to offset exposures denominated in the British pound, Euro, and Singapore dollar. Foreign-currency-denominated receivable and cash balances are remeasured at foreign exchange rates in effect on the balance sheet date with the effects of changes in foreign exchange rates reported in other income (expense), net. The forward contracts are not designated as hedges and are marked to market through other income (expense), net. Fair value changes in the forward contracts help mitigate the changes in the value of the remeasured receivable and cash balances attributable to changes in foreign exchange rates.

Debt Disclosure [Abstract]
Revolving Line of Credit	Revolving Line of CreditWe have a $400 million unsecured revolving line of credit with a syndicate of banks that expires on May 8, 2023 with an option to increase it, subject to lender approval, by another $100 million. Proceeds from the credit facility can be used for working capital and general corporate purposes and may also be used for the refinancing of existing debt, acquisitions and the repurchase of our common stock. Interest on amounts borrowed under the credit facility is based on (i) a base rate, which is the greater of (a) the prime rate, (b) the Federal Funds rate plus 0.500% and (c) the one-month LIBOR rate plus 1.000%, plus, in each case, an applicable margin, or (ii) an adjusted LIBOR rate plus an applicable margin. The applicable margin for base rate borrowings ranges from 0% to 0.875% and for LIBOR borrowings ranges from 1.000% to 1.875%, and is determined based on our consolidated leverage ratio. In addition, we must pay credit facility fees. The credit facility contains certain restrictive covenants including maintaining a maximum consolidated leverage ratio of 3.25 on an average trailing four-quarter basis, subject to a step up to 3.75 following certain permitted acquisitions; and a minimum interest coverage ratio of 3.00. The credit agreement also contains other covenants typical of unsecured facilities. As of March 31, 2021, we had $225.0 million in borrowings outstanding at a weighted-average interest rate of 1.236% and were in compliance with all financial covenants under this credit facility.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The effective income tax rates were 25.2% and 6.7% during the quarters ended March 31, 2021 and 2020, respectively, and 13.7% and (8.5)% during the six months ended March 31, 2021 and 2020, respectively. The provision for income taxes during interim quarterly reporting periods is based on our estimates of the effective tax rates for the full fiscal year. The effective tax rate in any quarter can also be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution. The effective tax rates for the six months ended March 31, 2021 and 2020 were both impacted by the recording of excess tax benefits relating to stock awards. In addition, stock exercises during the quarter and six months ended March 31, 2020 resulted in an additional increase in excess benefits.

Segment Reporting [Abstract]
Segment Information	Segment Information We are organized into the following three operating segments, each of which is a reportable segment, to align with internal management of our worldwide business operations based on product offerings. • Applications. This segment includes decision management applications designed for a specific type of business problem or process — such as marketing, account origination, customer management, fraud, financial crimes compliance, collections and insurance claims management — as well as associated professional services. These applications are available to our customers as on-premises software, and many are available as hosted, software-as-a-service (“SaaS”) applications through the FICO ® Analytic Cloud or Amazon Web Services (“AWS”). • Scores . This segment includes our business-to-business scoring solutions and services, our business-to-consumer scoring solutions and services including myFICO ® solutions for consumers, and associated professional services. Our scoring solutions give our clients access to analytics that can be easily integrated into their transaction streams and decision-making processes. Our scoring solutions and services are either distributed through major credit reporting agencies worldwide or sold to our clients directly. • Decision Management Software. This segment is composed of analytic and decision management software tools that clients can use to create their own custom decision management applications, our FICO ® Decision Management Suite, as well as associated professional services. Some of our decision management software is currently delivered as part of the FICO ® Decision Management Platform and is increasingly being adopted to connect decisioning solutions or previously disconnected use cases. These tools are available to our customers as on-premises software, through the FICO ® Analytic Cloud or AWS. Our Chief Executive Officer evaluates segment financial performance based on segment revenues and segment operating income. Segment operating expenses consist of direct and indirect costs principally related to personnel, facilities, consulting, travel and depreciation. Indirect costs are allocated to the segments generally based on relative segment revenues, fixed rates established by management based upon estimated expense contribution levels and other assumptions that management considers reasonable. We do not allocate broad-based incentive expense, share-based compensation expense, restructuring expense, amortization expense, various corporate charges and certain other income and expense measures to our segments. These income and expense items are not allocated because they are not considered in evaluating the segment’s operating performance. Our Chief Executive Officer does not evaluate the financial performance of each segment based on its respective assets, nor capital expenditures where depreciation amounts are allocated to the segments from their internal cost centers as described above.

Revenue from Contract with Customer [Abstract]
Contract Balances and Performance Obligations	Contract Balances and Performance Obligations Contract Balances We record a receivable when we satisfy a performance obligation prior to invoicing if only the passage of time is required before payment is due or if we have an unconditional right to consideration before we satisfy a performance obligation. We record a contract asset when we satisfy a performance obligation prior to invoicing but our right to consideration is conditional. We record deferred revenue when the payment is made or due before we satisfy a performance obligation. Receivables at March 31, 2021 and September 30, 2020 consisted of the following: March 31, September 30, (In thousands) Billed $ 155,838 $ 211,776 Unbilled 159,891 181,550 315,729 393,326 Less: allowance for doubtful accounts (4,931) (5,072) Net receivables 310,798 388,254 Less: long-term receivables * (45,994) (54,074) Short-term receivables * $ 264,804 334,180 * Short-term receivables and long-term receivables were recorded in accounts receivable, net and other assets, respectively, within the accompanying condensed consolidated balance sheets. Contract assets balance at March 31, 2021 and September 30, 2020 was immaterial. Deferred revenue primarily relates to our maintenance and SaaS contracts billed annually in advance and generally recognized ratably over the term of the service period. Significant changes in the deferred revenues balances during the six months ended March 31, 2021 were as follows: Six Months Ended (In thousands) Deferred revenues at September 30, 2020 * $ 122,141 Revenue recognized that was included in the deferred revenues balance at the beginning of the period (75,600) Increases due to billings, excluding amounts recognized as revenue during the period 78,945 Reclassified as liabilities related to assets held for sale $ (16,508) Deferred revenues at March 31, 2021 * $ 108,978 * Deferred revenues at September 30, 2020 included current portion of $115.2 million and long-term portion of $6.9 million that were recorded in deferred revenue and other liabilities, respectively, within the condensed consolidated balance sheets. Deferred revenues at March 31, 2021 included current portion of $100.4 million and long-term portion of $8.6 million that were recorded in deferred revenue and other liabilities, respectively, within the condensed consolidated balance sheets. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to provide customers with financing or to receive financing from our customers. Examples include multi-year on-premises licenses that are invoiced annually with revenue recognized upfront, and invoicing at the beginning of a SaaS subscription term with revenue recognized ratably over the contract period. Performance Obligations Revenue allocated to remaining performance obligations represents contracted revenue that will be recognized in future periods, which is comprised of deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. This does not include: • Revenue that will be recognized in future periods from usage-based royalty from license sales; • SaaS transactional revenue from variable considerations that will be recognized in the distinct service period during which it is earned; and • Revenue from variable considerations that will be recognized in accordance with the “right-to-invoice” practical expedient, such as fees from our professional services billed based on a time and materials basis. Revenue allocated to remaining performance obligations was $334.4 million as of March 31, 2021, of which we expect to recognize approximately 50% over the next 20 months and the remainder thereafter.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	ContingenciesWe are in disputes with certain customers regarding amounts owed in connection with the sale of certain of our products and services. We also have had claims asserted by former employees relating to compensation and other employment matters. We are also involved in various other claims and legal actions arising in the ordinary course of business. We record litigation accruals for legal matters which are both probable and estimable. For legal proceedings for which there is a reasonable possibility of loss (meaning those losses for which the likelihood is more than remote but less than probable), we have determined we do not have material exposure on an aggregate basis.

Discontinued Operations and Disposal Groups [Abstract]
Assets Held for Sale	Assets Held for Sale As discussed in Note 14 - Subsequent Events, we entered into an agreement to divest our Collections and Recovery business (“C&R”) on May 4th, 2021. As a result of meeting the criteria to classify the disposal group as held for sale under ASC 360, Property, Plant, and Equipment, the C&R disposal group was classified as held for sale as of March 31, 2021. Assets classified as held for sale are recorded at the lower of their carrying amount or fair value less costs to sell and are not depreciated or amortized. Classification of a disposal group as held for sale occurs when sufficient authority to sell the disposal group has been obtained, the disposal group is available for immediate sale, and its sale is probable within one year. If at any time these criteria are no longer met, the disposal group would be reclassified as held and used. We evaluate the held for sale classification during each reporting period. The C&R disposal group did not meet the requirements for presentation as discontinued operations and is included in income from continuing operations for the three and six months ended March 31, 2021. We did not have any assets held for sale as of September 30, 2020. The following table presents the carrying amounts of major classes of assets and liabilities related to assets held for sale with respect to the C&R disposal group as of March 31, 2021.

Fair Isaac Corporation	Fair Isaac Corporation Incorporated under the laws of the State of Delaware, Fair Isaac Corporation (“FICO”) is a provider of analytic, software and data management products and services that enable businesses to automate, improve and connect decisions. FICO provides a range of analytic solutions, credit scoring and credit account management products and services to banks, credit reporting agencies, credit card processing agencies, insurers, retailers, healthcare organizations and public agencies. In this Quarterly Report on Form 10-Q, Fair Isaac Corporation is referred to as “FICO,” “we,” “us,” “our,” or “the Company.”
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the applicable accounting guidance. Consequently, we have not necessarily included all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our financial position and results of operations. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our audited consolidated financial statements and notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. The interim financial information contained in this report is not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year. The condensed consolidated financial statements include the accounts of FICO and its subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates We make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the collectibility of accounts receivable; the appropriate levels of various accruals; variable considerations included in the transaction price for our customer contracts; labor hours in connection with fixed-fee service contracts; the amount of our tax provision; and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units and share-based compensation. Actual results may differ from our estimates. As the impact of the COVID-19 pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the condensed consolidated financial statements as new events occur and additional information becomes known. To the extent our actual results differ materially from those estimates and assumptions, our future financial statements could be affected. For more information, see Part II, Item 1A “Risk Factors” of this Quarterly Report on Form 10-Q.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-15, Intangibles—Goodwill and Other (Topic 350): Internal-Use Software (“ASU 2018-15”). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted ASU 2018-15 in the first quarter of our fiscal 2021 and the adoption did not have a significant impact on our condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04, ASU 2019-05 and ASU 2019-11 (collectively, “Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted Topic 326 in the first quarter of our fiscal 2021 and the adoption did not have a significant impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted We do not expect that any recently issued accounting pronouncements will have a significant effect on our financial statements.
