Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited consolidated financial statements of CACI International Inc and subsidiaries (CACI or the Company) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and include the assets, liabilities, results of operations, comprehensive income and cash flows for the Company, including its subsidiaries and ventures that are majority-owned or otherwise controlled by the Company. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. All intercompany balances and transactions have been eliminated in consolidation. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts. The fair value of the Company’s debt outstanding as of March 31, 2021 under its bank credit facility approximates its carrying value. The fair value of the Company’s debt under its bank credit facility was estimated using Level 2 inputs based on market data of companies with a corporate rating similar to CACI’s that have recently priced credit facilities. See Notes 11 and 18. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments and reclassifications (all of which are of a normal, recurring nature) that are necessary for the fair presentation of the periods presented. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s latest annual report to the SEC on Form 10-K for the year ended June 30, 2020. The results of operations for the three and nine months ended March 31, 2021 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year.

Business Combinations [Abstract]
Acquisition	3. Acquisition On August 11, 2020, CACI completed the acquisition of Ascent Vision Technologies (AVT) for a purchase price of approximately $348.8 million. AVT specializes in Electro-Optical Infrared payloads, On-Board Computer Vision Processing and counter-unmanned aircraft system (C-UAS) solutions. The Company preliminarily recognized fair values of the assets acquired and liabilities assumed and allocated $211.0 million to goodwill and $133.8 million to intangible assets. The goodwill of $211.0 million is largely attributable to the assembled workforce of AVT and expected synergies between the Company and AVT. The intangible assets consist of customer relationships of $65.7 million and technology of $68.1 million. The fair value attributed to intangible assets is being amortized on an accelerated basis over approximately 20 years for customer relationships and over approximately 10 years for technology. The fair value attributed to the intangible assets acquired was based on assumptions and other information compiled by management, including independent valuations that utilized established valuation techniques. Of the value attributed to goodwill and intangible assets, approximately $319.7 million is deductible for income tax purposes.

For these revenue arrangements, revenue is recognized over time primarily using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. The EAC process requires the Company to use professional judgment when assessing risks, estimating contract revenue and costs, estimating variable consideration, and making assumptions for schedule and technical issues. The Company periodically reassesses its EAC assumptions and updates its estimates as needed. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. Based on changes in a contract’s EAC, a cumulative adjustment to revenue will be recorded. For the three and nine months ended March 31, 2021, we recognized an increase to income before income taxes of $10.7 million ($0.31 per diluted share) and $36.6 million ($1.06 per diluted share), respectively, compared with $8.3 million ($0.24 per diluted share) and $32.1 million ($0.93 per diluted share) for the three and nine months ended March 31, 2020, respectively, Revenue recognized from previously satisfied performance obligations was $0.7 million and $2.3 million for the three and nine months ended March 31, 2021, respectively, compared with $(0.3) million and $9.9 million for the three and nine months ended March 31, 2020, respectively. The change in revenue generally relates to final true-up adjustments to our estimated award or incentive fees in the period in which we receive the customer’s final performance score or when we can determine that more objective, contractually-defined criteria have been fully satisfied. Remaining Performance Obligations The Company’s remaining performance obligations balance as of period end represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts. This balance excludes unexercised contract option years and task orders that may be issued underneath an Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle until such task orders are awarded. The remaining performance obligations balance generally increases with the execution of new contracts and converts into revenue as our contractual performance obligations are satisfied. The Company continues to monitor this balance as it is subject to change from execution of new contracts, contract modifications or extensions, government deobligations, or early terminations. Based on this analysis, an adjustment to the period end balance may be required. Our remaining performance obligations balance as of March 31, 2021 was $6.7 billion. The Company expects to recognize approximately 90 percent of our remaining performance obligations balance as revenue over the next twelve months and the remaining 10 percent thereafter

Revenue From Contract With Customer [Abstract]
Contract Balances	8. Contract Balances Contract assets are primarily comprised of unbilled receivables in which revenue has been recognized but our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables. The incremental costs of obtaining a contract (e.g. sales commissions) are capitalized as an asset when the Company expects to recover them either directly or indirectly through the revenue arrangement’s profit margins. These capitalized costs are subsequently expensed over the revenue arrangement’s period of performance. Contract assets are not stated above their net realizable value. Contract liabilities are primarily comprised of advance payments in which consideration is received in advance of satisfying a performance obligation. The advance payment is subsequently recognized into revenue as the performance obligation is satisfied. Net contract assets (liabilities) consisted of the following (in thousands): March 31, June 30, Description of Contract Related Balance Financial Statement Classification 2021 2020 Contract assets – current: Unbilled receivables Accounts receivable, net $ 110,191 $ 61,888 Costs to obtain – short-term Prepaid expenses and other current assets 4,064 3,492 Contract assets – noncurrent: Unbilled receivables Accounts receivable, long-term 11,802 9,629 Costs to obtain – long-term Other long-term assets 9,546 7,708 Contract liabilities – current: Deferred revenue and other contract liabilities – short-term Other accrued expenses and current liabilities (59,323 ) (57,082 ) Contract liabilities – noncurrent: Deferred revenue and other contract liabilities – long-term Other long-term liabilities (6,543 ) (6,507 ) Net contract assets (liabilities) $ 69,737 $ 19,128 During the three and nine months ended March 31, 2021, we recognized $4.2 million and $57.1 million of revenue, respectively, compared with $6.2 million and $44.9 million of revenue , respectively,

(the Purchaser), for the sale of certain designated eligible U.S. government receivables. The amendment extended the term of the MARPA to December 23, 2021. Under the MARPA, the Company can sell eligible receivables, including certain billed and unbilled receivables up to a maximum amount of $200.0 million. The Company’s receivables are sold under the MARPA without recourse for any U.S. government credit risk. The Company accounts for receivable transfers under the MARPA as sales under ASC 860, Transfers and Servicing The Company does not retain an ongoing financial interest in the transferred receivables other than cash collection and administrative services. The Company estimated that its servicing fee was at fair value and therefore no servicing asset or liability related to these receivables was recognized as of March 31, 2021. Proceeds from the sold receivables are reflected in our operating cash flows on the statement of cash flows. MARPA activity consisted of the following (in thousands): As of and for the Nine Months Ended March 31, 2021 2020 Beginning balance: $ 200,000 $ 192,527 Sales of receivables 2,048,585 1,750,496 Cash collections (2,058,725 ) (1,749,524 ) Outstanding balance sold to Purchaser: (1) 189,860 193,499 Cash collected, not remitted to Purchaser (2) (76,388 ) (55,588 ) Remaining sold receivables $ 113,472 $ 137,911 (1) For the nine months ended March 31, 2021 and 2020, the Company recorded a net cash outflow of $10.1 million and a net cash inflow of $1.0 million in its cash flows from operating activities, respectively, from sold receivables.

The Revolving Facility has subfacilities of $100.0 million for same-day swing line loan borrowings and $25.0 million for stand-by letters of credit. The Revolving Facility is a secured facility that permits continuously renewable borrowings of up to $1,500.0 million. As of March 31, 2021, the Company had $1,020.0 million outstanding under the Revolving Facility and no borrowings on the swing line. The Company pays a quarterly facility fee for the unused portion of the Revolving Facility. The Term Loan is a five-year The interest rates applicable to loans under the Credit Facility are floating interest rates that, at the Company’s option, equal a base rate or a Eurodollar rate plus, in each case, an applicable rate based upon the Company’s consolidated total leverage ratio. As of March 31, 2021, the effective interest rate, including the impact of the Company’s floating-to-fixed interest rate swap agreements and excluding the effect of amortization of debt financing costs, for the outstanding borrowings under the Credit Facility was 1.97 percent. The Credit Facility requires the Company to comply with certain financial covenants, including a maximum total leverage ratio and a minimum interest coverage ratio. The Credit Facility also includes customary negative covenants restricting or limiting the Company’s ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or investments, transfer assets, declare dividends or redeem or repurchase capital stock or make other distributions, prepay subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case except as expressly permitted under the Credit Facility. As of March 31, 2021, the Company was in compliance with all of the financial covenants. A majority of the Company’s assets serve as collateral under the Credit Facility. All debt issuance costs are being amortized from the date incurred to the expiration date of the Credit Facility.

The Company has entered into several floating-to-fixed interest rate swap agreements for an aggregate notional amount of $800.0 million which hedge a portion of the Company’s floating rate indebtedness. The swaps mature at various dates through 2026. The Company has designated the swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The interest rate swap agreements are highly correlated to the changes in interest rates to which the Company is exposed. Realized gains and losses in connection with each required interest payment are reclassified from accumulated other comprehensive income or loss to interest expense. The Company does not hold or issue derivative financial instruments for trading purposes.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	1 3 . Commitments and Contingencies The Company is involved in various lawsuits, claims, and administrative proceedings arising in the normal course of business. Management is of the opinion that any liability or loss associated with such matters, either individually or in the aggregate, will not have a material adverse effect on the Company’s operations and liquidity. Government Contracting Payments to the Company on cost-plus-fee and T&M contracts are subject to adjustment upon audit by the Defense Contract Audit Agency (DCAA) and other government agencies that do not utilize DCAA’s services. The DCAA has completed audits of the Company’s annual incurred cost proposals through fiscal year 2019. We are still negotiating the results of prior years’ audits with the respective cognizant contracting officers and believe our reserves for such are adequate. In the opinion of management, adjustments that may result from these audits and the audits not yet started are not expected to have a material effect on the Company’s financial position, results of operations, or cash flows as the Company has accrued its best estimate of potential disallowances. Additionally, the DCAA continually reviews the cost accounting and other practices of government contractors, including the Company. In the course of those reviews, cost accounting and other issues are identified, discussed and settled.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	1 8 . Fair Value of Financial Instruments ASC 820, Fair Value Measurements and Disclosures The Company’s financial assets and liabilities recorded at fair value on a recurring basis are categorized based on the priority of the inputs used to measure fair value. The inputs used in measuring fair value are categorized into three levels, as follows: • Level 1 Inputs – unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 Inputs – unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. • Level 3 Inputs – amounts derived from valuation models in which unobservable inputs reflect the reporting entity’s own assumptions about the assumptions of market participants that would be used in pricing the asset or liability. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2021 and June 30, 2020, and the level they fall within the fair value hierarchy (in thousands): March 31, June 30, Financial Statement Fair Value 2021 2020 Description of Financial Instrument Classification Hierarchy Fair Value Interest rate swap agreements Other accrued expenses and current liabilities Level 2 $ 1,934 $ — Interest rate swap agreements Other long-term liabilities Level 2 $ 25,817 $ 43,168 Changes in the fair value of the interest rate swap agreements are recorded as a component of accumulated other comprehensive income or loss.

Accelerated Share Repurchase	19. Accelerated Share Repurchase On March 12, 2021, CACI entered into an accelerated share repurchase agreement (the “ASR Agreement”) with JPMorgan Chase Bank, National Association (JPMorgan). Under the ASR Agreement, we paid $500.0 million to JPMorgan and received an initial delivery of approximately 1.7 million shares of our common stock, which shares were recorded as a $400.0 million increase to treasury stock. The final number of shares to be repurchased will be based on the volume-weighted average stock price of our common stock during the term of the agreement, less a discount. This is evaluated as an unsettled forward contract indexed to our own stock, with $100.0 million classified within stockholders’ equity as additional paid-in-capital. The ASR Agreement is scheduled to settle prior to the end of the second quarter of FY2022. At final settlement, JPMorgan may be required to deliver additional shares of our common stock to us or, under certain circumstances, we may elect to make a cash payment or deliver shares of our common stock to JPMorgan.
