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, 2019 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 10 and 16. 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, 2018. The results of operations for the three and nine months ended March 31, 2019 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year. Certain reclassifications have been made to the prior period’s financial statements to conform to the current presentation.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedge Activities In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments In February 2016, the FASB issued ASU 2016-02, Leases In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers Effective July 1, 2018, we adopted ASC 606 using the modified retrospective method, whereby the cumulative effect of applying the standard was recognized through shareholders’ equity on the date of adoption. In addition, for our fiscal year ending June 30, 2019 and the interim reporting periods therein, the Company is required to disclose the amount by which each financial statement line item was affected by the new standard. The Company’s comparative information, for prior periods presented before July 1, 2018, has not been restated and continues to be reported under ASC 605. The impact of adoption on our consolidated balance sheet is as follows (in thousands): June 30, 2018 As Reported Under ASC 605 Adjustments Due to ASC 606 July 1, 2018 Balance Under ASC 606 Assets: Accounts receivable, net $ 806,871 $ 20,454 $ 827,325 Prepaid expenses and other current assets 58,126 2,342 60,468 Other long-term assets 39,175 3,923 43,098 Liabilities and Shareholders' Equity: Other accrued expenses and current liabilities 150,602 2,212 152,814 Deferred income taxes 200,880 6,639 207,519 Other long-term liabilities 85,187 98 85,285 Retained earnings 2,126,790 17,770 2,144,560 ASC 606 changed the pattern of revenue recognition for some of our contracts with customers. For our award and incentive fee contracts, we recognize an estimated amount of variable consideration throughout the performance period rather than defer recognition of the relevant portion of fee until customer notification of the amount earned. Some of our fixed price services-type contracts in which revenue was previously recognized on a straight-line basis over the performance period converted to recognition of revenue using a cost-to-cost input method to measure our progress towards the complete satisfaction of the performance obligation. The cumulative effect of these changes in the pattern of revenue recognition resulted in an increase to accounts receivable with an offset to retained earnings. In addition, ASC 606 changed the timing of revenue recognition for license renewal performance obligations. Under prior GAAP, license renewals were generally recognized in the period the renewal contract was executed. However, upon adoption of ASC 606, revenue for a license renewal may not be recognized until the start of the term of the renewal. The cumulative effect of this change resulted in an increase to contract liabilities with an offset to retained earnings. The adoption of ASC 606 did not have a material impact on the Company’s revenue recognition for cost-plus-fee, fixed price/level-of-effort, time-and-materials (T&M), fixed price contracts previously recognized under ASC 605-35, and fixed price product revenue arrangements. Under ASC 340-40, the Company capitalizes certain costs to fulfill and obtain a contract. The cumulative effect of this change resulted in an increase to contract assets with an offset to retained earnings. These capitalized costs are amortized over the period of contract performance as revenue is recognized from the transfer of goods or services and the underlying performance obligation is satisfied. The table below presents the impact of adoption of ASC 606 on our consolidated statement of operations for the three and nine months ended March 31, 2019 (in thousands, except per share data): Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 As Adjusted Under ASC 605 Effect of ASC 606 As Reported Under ASC 606 As Adjusted Under ASC 605 Effect of ASC 606 As Reported Under ASC 606 Revenue $ 1,263,174 $ 1,784 $ 1,264,958 $ 3,599,511 $ 12,952 $ 3,612,463 Costs of revenue: Direct costs 824,024 — 824,024 2,397,633 — 2,397,633 Indirect costs and selling expenses 324,597 231 324,828 860,294 (1,032 ) 859,262 Depreciation and amortization 21,198 — 21,198 58,797 — 58,797 Total costs of revenue 1,169,819 231 1,170,050 3,316,724 (1,032 ) 3,315,692 Income from operations 93,355 1,553 94,908 282,787 13,984 296,771 Interest expense and other, net 13,466 — 13,466 31,773 — 31,773 Income before taxes 79,889 1,553 81,442 251,014 13,984 264,998 Income tax expense 12,875 422 13,297 45,820 3,604 49,424 Net income $ 67,014 $ 1,131 $ 68,145 $ 205,194 $ 10,380 $ 215,574 Basic earnings per share $ 2.70 $ 0.05 $ 2.74 $ 8.27 $ 0.42 $ 8.69 Diluted earnings per share $ 2.64 $ 0.04 $ 2.69 $ 8.09 $ 0.41 $ 8.50 For the three months ended March 31, 2019, the effect of ASC 606 was primarily related to certain fixed price services-type contracts in which revenue was previously recognized on a straight-line basis that converted to a cost-to-cost input method to measure the Company’s progress towards the complete satisfaction of the performance obligation. For the nine months ended March 31, 2019, the effect of ASC 606 was primarily related to the timing of award and incentive fee revenue recognition.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Revenue Recognition The Company generates almost all of our revenue from three different types of contractual arrangements with the U.S. government: cost-plus-fee, time-and-materials (T&M), and fixed-price contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services. We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and it is probable that we will collect substantially all of the consideration. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires significant professional judgment as it may impact the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation. When determining the total transaction price, the Company identifies both fixed and variable consideration elements within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenue. Throughout the performance period, we recognize as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. Our estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which we can calculate the final amount of award or incentive fee earned - based on the receipt of the customer’s final performance score or determining that more objective, contractually-defined criteria have been fully satisfied - the Company will adjust our cumulative revenue recognized to date on the contract. This adjustment to revenue will be disclosed as the amount of revenue recognized in the current period for a previously satisfied performance obligation. We generally recognize revenue over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on our services-type revenue arrangements. This continuous transfer of control for our U.S. government contracts is supported by the unilateral right of our customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For our services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. We use a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including: costs incurred, labor hours expended, and time-elapsed measures for our fixed-price stand ready obligations. For certain contracts, primarily our cost-plus and T&M services-type revenue arrangements, we apply the right-to-invoice practical expedient in which revenue is recognized in direct proportion to our present right to consideration for progress towards the complete satisfaction of the performance obligation. When a performance obligation has a significant degree of interrelation or interdependence between one month’s deliverables and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion methodology. For these revenue arrangements, substantially all revenue is recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. 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. Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. When a contract modification changes the scope or price and the additional performance obligations are at their standalone selling price, the original contract is terminated and the Company accounts for the change prospectively when the new goods or services to be transferred are distinct from those already provided. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenue based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation. Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and our knowledge of available funding for the contract or program. Contract Assets Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables. In addition, the costs to fulfill a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g. ramp up costs at the beginning of the period of performance) may be capitalized when expenses are incurred prior to satisfying a performance obligation. 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. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception. Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value. Contract Liabilities Contract liabilities include advance payments received from the customer in excess of revenue that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenue as the performance obligation is satisfied. Remaining Performance Obligations The Company’s remaining performance obligations balance represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts as of period end. The remaining performance obligations balance excludes unexercised contract option years and task orders that may be issued underneath an Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle. 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 our remaining performance obligations 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.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions SE&A BU On August 15, 2018, CACI acquired certain assets of the systems engineering and acquisition support services business unit (SE&A BU) of CSRA LLC, a managed affiliate of General Dynamics Information Technology, Inc. The initial purchase consideration paid at closing to acquire the SE&A BU was $84.0 million plus $6.0 million representing a preliminary net working capital adjustment. Subsequent to closing, CACI estimated that an additional payment may be due to the sellers for the final net working capital adjustment. The Company recognized fair values of the assets acquired and liabilities assumed and allocated $42.8 million to goodwill and $8.9 million to intangible assets. The intangible assets consist of customer relationships. The final purchase price allocation, which is provisional and is expected to be completed by Q1 FY2020, will be based on final appraisals and other analysis of fair values of acquired assets and liabilities. The Company does not expect that differences between the preliminary and final purchase price allocation will have a material impact on its results of operations or financial position. Mastodon On January 29, 2019, CACI acquired all of the equity interests of Mastodon Design LLC (Mastodon) for a purchase consideration of $225.0 million, which includes a $220.0 million initial cash payment and $5.0 million of deferred consideration. Mastodon specializes in the rapid design of rugged tactical communications, signals intelligence (SIGINT) and electronic warfare (EW) equipment. The Company recognized fair values of the assets acquired and liabilities assumed and allocated $139.3 million to goodwill and $83.9 million to intangible assets. The goodwill of $139.3 million is largely attributable to the assembled workforce of Mastodon and expected synergies between the Company and Mastodon. The intangible assets consist of customer relationships of $19.8 million and technology of $64.1 million. The estimated fair value attributed to intangible assets is being amortized on an accelerated basis over approximately 20 years for customer relationships and over a range of approximately 5 to 9 years for technology. The fair value attributed to the intangible assets acquired was based on preliminary estimates, 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 $223.1 million is deductible for income tax purposes. The final purchase price allocation, which is provisional and is expected to be completed by Q3 FY2020, will be based on final appraisals and other analysis of fair values of acquired assets and liabilities. LGS On March 1, 2019, CACI acquired all of the equity interests of Legos Intermediate Holdings, LLC and MDCP Legos Blocker, Inc., the parent companies of LGS Innovations (LGS). The purchase consideration is approximately $759.5 million, which includes $759.9 million of cash paid at close net of cash acquired and a $0.4 million estimated net purchase price reduction for returnable consideration due from the seller, deferred consideration, and estimated post-close net working capital adjustments. LGS is a leading provider of SIGINT and cyber products and solutions to the Intelligence Community and Department of Defense. CACI is in the process of finalizing its valuation of all the assets acquired and liabilities assumed. As the amounts recorded for certain assets and liabilities are preliminary in nature, they are subject to adjustment as additional information is obtained about the facts and circumstances that existed at the acquisition date. The final determination of fair values of certain assets and liabilities will be completed within the measurement period of up to one-year from the acquisition date as permitted under GAAP. The LGS acquisition could necessitate the need to use the full one-year measurement period to adequately analyze and assess several factors used in establishing the asset and liability fair values as of the acquisition date, including intangible assets, receivables, inventory, deferred revenue, deferred taxes, income tax obligations, and certain reserves. Any potential adjustments made could be material in relation to the preliminary values presented in the table below. Based on the Company’s preliminary valuation, the total estimated consideration of $759.5 million has been allocated to assets acquired and liabilities assumed as follows (in thousands): Accounts receivable $ 92,876 Prepaid expenses and other current assets 21,033 Property and equipment 23,282 Intangible assets 147,650 Goodwill 521,630 Accounts receivable, long-term 2,180 Other long-term assets 877 Accounts payable (10,309 ) Accrued compensation and benefits (22,339 ) Other accrued expenses and current liabilities (9,185 ) Deferred income taxes 71 Other long-term liabilities (8,288 ) Total estimated consideration $ 759,478 The goodwill of $521.6 million is largely attributable to the assembled workforce of LGS and expected synergies between the Company and LGS. The intangible assets consist of customer relationships of $86.9 million and technology of $60.8 million. The estimated fair value attributed to intangible assets is being amortized on an accelerated basis over approximately 20 years for customer relationships and over a range of approximately 5 to 15 years for technology. The fair value attributed to the intangible assets acquired was based on preliminary estimates, 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 $615.8 million is deductible for income tax purposes. From the March 1, 2019 acquisition date through March 31, 2019, LGS generated $32.8 million of revenue and $1.3 million of net income. LGS’ net income includes the impact of $1.3 million of amortization of intangibles. LGS’ net income does not include the impact of acquisition-related expenses incurred by CACI. CACI incurred $11.3 million of acquisition-related expenses during the nine months ended March 31, 2019, which are included in indirect costs and selling expenses. Additionally, CACI incurred $2.7 million of integration and restructuring costs from the acquisition date through March 31, 2019. The following pro forma results are prepared for comparative purposes only and do not necessarily reflect the results that would have occurred had the acquisition occurred at the beginning of the years presented or the results which may occur in the future. The following unaudited pro forma results of operations assume the LGS acquisition had occurred on July 1, 2017 (in thousands, except per share amounts): Nine Months Ended March 31, 2019 2018 Revenue $ 3,897,994 $ 3,558,381 Net income 225,538 238,453 Basic EPS 9.09 9.70 Diluted EPS 8.89 9.45 Significant pro forma adjustments incorporated into the pro forma results above include the recognition of additional amortization expense related to acquired intangible assets and additional interest expense related to debt incurred to finance the acquisition. Significant nonrecurring adjustments include the elimination of non-recurring acquisition-related expenses incurred during the nine months ended March 31, 2019.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	7. Revenue Recognition We disaggregate our revenue arrangements by contract type, customer, and whether the Company performs on the contract as the prime or subcontractor. We believe that these categories allow for a better understanding of the nature, amount, timing, and uncertainty of revenue and cash flows arising from our contracts. Revenue by Contract Type The Company generated revenue on our cost-plus-fee, firm fixed-price (including proprietary software product sales), and time-and-materials contracts as follows during the three and nine months ended March 31, 2019 (in thousands): Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 Domestic International Total Domestic International Total Cost-plus-fee $ 704,627 $ — $ 704,627 $ 2,003,204 $ — $ 2,003,204 Firm fixed-price 348,143 25,863 374,006 982,232 73,152 1,055,384 Time and materials 172,761 13,564 186,325 509,170 44,705 553,875 Total $ 1,225,531 $ 39,427 $ 1,264,958 $ 3,494,606 $ 117,857 $ 3,612,463 Customer Information The Company generated revenue from our primary customer groups as follows during the three and nine months ended March 31, 2019 (in thousands): Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 Domestic International Total Domestic International Total Department of Defense $ 887,030 $ — $ 887,030 $ 2,540,093 $ — $ 2,540,093 Federal civilian agencies 318,374 — 318,374 898,491 — 898,491 Commercial and other 20,127 39,427 59,554 56,022 117,857 173,879 Total $ 1,225,531 $ 39,427 $ 1,264,958 $ 3,494,606 $ 117,857 $ 3,612,463 Prime or Subcontractor The Company generated revenue as either the prime or subcontractor as follows during the three and nine months ended March 31, 2019 (in thousands): Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 Domestic International Total Domestic International Total Prime contractor $ 1,114,172 $ 39,427 $ 1,153,599 $ 3,217,570 $ 117,857 $ 3,335,427 Subcontractor 111,359 — 111,359 277,036 — 277,036 Total $ 1,225,531 $ 39,427 $ 1,264,958 $ 3,494,606 $ 117,857 $ 3,612,463 Significant Estimates The Company uses an estimate at completion (EAC) as the basis to measure progress towards the complete satisfaction of its contractual performance obligations, for each of its contracts in which revenue is recognized using a percentage of completion calculation. 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. Based on changes in a contract’s EAC, a cumulative adjustment to revenue will be recorded. During the three and nine months ended March 31, 2019, we recognized an increase to income before income taxes of $6.3 million ($0.18 per diluted share) and $16.9 million ($0.49 per diluted share), respectively, from EAC adjustments. The Company used its statutory tax rate when calculating the impact to diluted earnings per share. The Company records final true-up adjustments to its 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. These final true-up adjustments are disclosed as revenue recognized from previously satisfied performance obligations. For the three and nine months ended March 31, 2019, the revenue recognized from previously satisfied performance obligations was $0.8 million and $1.1 million, respectively. 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 IDIQ vehicle. Our remaining performance obligations balance as of March 31, 2019 was $6.7 billion. The Company expects to recognize approximately 72.0 percent of our remaining performance obligations balance as revenue over the next year and the remaining 28.0 percent thereafter.

Transfers And Servicing Of Financial Assets [Abstract]
Sales of Receivables	9. Sales of Receivables On December 28, 2018, the Company entered into a Master Accounts Receivable Purchase Agreement (MARPA Facility) with MUFG Bank, Ltd. (the Purchaser), for the sale of certain designated eligible U.S. government receivables. The MARPA Facility has an initial term of one-year. Under the MARPA Facility, 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 Facility without recourse for any U.S. government credit risk. The Company accounts for receivable transfers under the MARPA Facility 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, 2019. Proceeds from the sold receivables are reflected in our operating cash flows on the statement of cash flows. During the three and nine months ended March 31, 2019, the Company sold $563.5 million of receivables. The amount outstanding as of March 31, 2019 was $200.0 million. As of March 31, 2019, collections not remitted to the Purchaser related to the sold receivables were $72.0 million. This amount represents an obligation to the Purchaser and is included in other accrued expenses and current liabilities in the accompanying consolidated balance sheet. During the three and nine months ended March 31, 2019, the Company incurred purchase discount fees of $1.4 million, which are recorded within interest expense and other, net in our accompanying consolidated statements of operations. MARPA Facility activity consisted of the following (in thousands): As of and for the As of and for the Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 Beginning balance: Sales of receivables $ 563,502 $ 563,502 Cash collections (363,502 ) (363,502 ) Outstanding balance sold to Purchaser: (1) 200,000 200,000 Cash collected, not remitted to Purchaser (2) (71,970 ) (71,970 ) Remaining sold receivables $ 128,030 $ 128,030 (1) Represents the increase to cash flows from operations.

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, 2019, the Company had $865.0 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 secured facility under which principal payments are due in quarterly installments of $11.7 million through June 30, 2021 and $23.5 million thereafter until the balance is due in full on June 30, 2023. As of March 31, 2019, the Company had $903.2 million outstanding under the Term Loan. 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, 2019, 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 3.53 percent. The Credit Facility requires the Company to comply with certain financial covenants, including a maximum total leverage ratio and a minimum fixed charge 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, 2019, 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. Cash Flow Hedges The Company periodically uses derivative financial instruments as part of a strategy to manage exposure to market risks associated with interest rate fluctuations. The Company has entered into several floating-to-fixed interest rate swap agreements for an aggregate notional amount of $400.0 million which hedge a portion of the Company’s floating rate indebtedness. The swaps mature at various dates through 2022. 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 1 . 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 is nearing completion of audits of the Company’s annual incurred cost submissions through fiscal year 2016 and is auditing the Company’s incurred cost submissions for its fiscal years 2017 and 2018. 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.

Stock-Based Compensation Stock-based compensation expense recognized, together with the income tax benefits recognized, is as follows (in thousands): Three Months Ended Nine Months Ended March 31, March 31, 2019 2018 2019 2018 Stock-based compensation related to RSUs included in indirect costs and selling expense $ 6,304 $ 5,794 $ 18,351 $ 18,183 Income tax benefit recognized for stock-based compensation expense $ 1,032 $ 1,905 $ 3,422 $ 5,979 Under the terms of the 2016 Amended and Restated Incentive Compensation Plan (the 2016 Plan), the Company may issue, among others, non-qualified stock options, restricted stock, restricted stock units (RSUs), stock settled appreciation rights (SSARs), and performance awards, collectively referred to herein as equity instruments. The 2016 Plan was approved by the Company’s stockholders in November 2016 and amended and restated the 2006 Stock Incentive Plan (the 2006 Plan) which was due to expire at the end of the ten-year period. Previous grants that were made under the 2006 Plan, and equity instruments granted prior to approval of the 2016 Plan continue to be governed by the terms of the 2006 Plan. During the periods presented all equity instrument grants were made in the form of RSUs. Other than performance-based RSUs (PRSUs) which contain a market-based element, the fair value of RSU grants was determined based on the closing price of a share of the Company’s common stock on the date of grant. The fair value of RSUs with market-based vesting features was also measured on the grant date, but was done so using a binomial lattice model. Annual grants under the 2016 Plan, and previously the 2006 Plan, are generally made to the Company’s key employees during the first quarter of the Company’s fiscal year and to members of the Company’s Board of Directors during the second quarter of the Company’s fiscal year. With the approval of its Chief Executive Officer, the Company also issues equity instruments to strategic new hires and to employees who have demonstrated superior performance. The Company granted performance-based stock awards to key employees in October of 2018 and September of 2017 and 2016. The final number of PRSUs that are earned by participants and vest is based on the achievement of a specified EPS for the fiscal year and on the average share price for the 90-day period ended for the following three years. If the 90-day average share price of the Company’s stock in years one, two and three exceeds the 90-day average share price at the grant date by 100 percent or more the number of shares ultimately awarded could range up to 200 percent of the specified target award. In addition to the performance and market conditions, there is a service vesting condition that stipulates 50 percent of the award will vest approximately three years from the grant date and 50 percent will vest approximately four years from the grant date, depending on the award date. The annual performance-based awards granted for each of the fiscal years presented were as follows: Performance-based stock awards granted Number of additional shares earned under performance-based stock awards Fiscal year 2019 101,976 — Fiscal year 2018 185,056 20,116 Fiscal year 2017 193,420 73,065 The total number of shares authorized by shareholders for grants under the 2016 Plan and its predecessor plan is 1,200,000 plus any forfeitures from the 2006 Plan. The aggregate number of grants that may be made may exceed this approved amount as forfeited RSUs become available for future grants. As of March 31, 2019, cumulative grants of 589,893 equity instruments underlying the shares authorized have been awarded, and 134,010 of these instruments have been forfeited. Activity related to RSUs during the nine months ended March 31, 2019 is as follows: RSUs Unvested at June 30, 2018 663,987 Granted 271,266 Vested (263,702 ) Forfeited (28,643 ) Unvested at March 31, 2019 642,908 Weighted-average grant date fair value for RSUs $ 201.31 As of March 31, 2019, there was $48.8 million of total unrecognized compensation costs related to RSUs scheduled to be recognized over a weighted-average period of 2.7 years.

Income Tax Disclosure [Abstract]
Income Taxes	1 4 . Income Taxes The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require the application of significant judgment. The Company is currently under examination by the Internal Revenue Service for the year 2015, one state jurisdiction for the years 2015 through 2017 and one foreign jurisdiction for the years 2011 through 2015. The Company does not expect resolution of these examinations to have a material impact on its results of operations, financial condition or cash flows. The Company’s total liability for unrecognized tax benefits as of March 31, 2019 and June 30, 2018 was $4.4 million and $4.1 million, respectively. The $4.4 million unrecognized tax benefit at March 31, 2019, if recognized, would impact the Company’s effective tax rate. For the three months ended March 31, 2019, the effective income tax rate was 16.3 percent compared with 31.6 percent for the same period last year. The Company’s effective income tax rate decreased primarily due to: the full-year impact of the lower U.S. income tax rate pursuant to the Tax Cuts and Jobs Act of 2017 (TCJA); writing off certain historic deferred tax balances due to an internal reorganization related to the integration of an acquired company; and from changes in our estimated benefit from the federal research and development tax credit. For both comparative reporting periods, the Company’s effective tax rate was impacted by excess tax benefits under ASU 2016-09, Stock Compensation For the nine months ended March 31, 2019, the effective income tax rate was 18.7 percent compared with (9.6) percent for the same period last year. For the nine months ended March 31, 2019, the Company’s effective income tax rate increased year-over-year due to the favorable remeasurement of the Company's deferred tax liability pursuant to the TCJA in the prior year, partially offset by: the full-year impact of the lower U.S. income tax rate pursuant to the TCJA; writing off certain historic deferred tax balances due to an internal reorganization related to the integration of an acquired company; and from changes in our estimated benefit from the federal research and development tax credit. For both comparative reporting periods, the Company’s effective tax rate was impacted by excess tax benefits under ASU 2016-09 and the change in value of assets invested in COLI policies. If gains or losses on the COLI investments throughout the rest of the current fiscal year vary from our estimates, our FY2019 effective tax rate will fluctuate in future quarters for the year ending June 30, 2019. Tax Cuts and Jobs Act The TCJA was enacted on December 22, 2017. Among other things, the TCJA reduced the U.S. federal corporate tax rate from 35.0 percent to 21.0 percent effective January 1, 2018. Prior to the expiration of the one-year measurement period of Staff Accounting Bulletin No. 118 on December 22, 2018, the Company finalized its tax reform positions related to: (1) transition tax liability; (2) remeasurement of deferred taxes; and (3) the limitation on the deductibility of certain executive compensation. In prior periods, the Company was able to make reasonable estimates and record provisional amounts for each of these elements. During the nine months ended March 31, 2019, the Company recognized a $2.2 million tax benefit related to the reduction of our provisional calculation of the one-time transition tax liability and a $0.5 million tax benefit related to its final analysis of its deferred tax remeasurement. No other adjustments were made to FY2018 provisional amounts during the nine months ended March 31, 2019.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	1 6 . 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 Company’s financial instruments measured at fair value included interest rate swap agreements and contingent consideration in connection with business combinations. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2019 and June 30, 2018, and the level they fall within the fair value hierarchy (in thousands): March 31, June 30, Financial Statement Fair Value 2019 2018 Description of Financial Instrument Classification Hierarchy Fair Value Contingent consideration Other accrued expenses and current liabilities Level 3 $ 11,300 $ 693 Contingent consideration Other long-term liabilities Level 3 $ — $ 11,000 Interest rate swap agreements Prepaid expenses and other current assets Level 2 $ 227 $ 672 Interest rate swap agreements Other long-term assets Level 2 $ 6,203 $ 13,405 Changes in the fair value of the interest rate swap agreements are recorded as a component of accumulated other comprehensive income or loss. Various acquisitions completed during prior fiscal years contained provisions requiring that the Company pay contingent consideration in the event the acquired businesses achieved certain specified earnings results during the two and three year periods subsequent to each acquisition. The Company determined the fair value of the contingent consideration as of each acquisition date using a valuation model which included the evaluation of the most likely outcome and the application of an appropriate discount rate. At the end of each reporting period, the fair value of the contingent consideration was remeasured and any changes were recorded in indirect costs and selling expenses. During the nine months ended March 31, 2019 this remeasurement resulted in a $0.3 million change to the liability recorded.

Accounting Policies [Abstract]
Basis of Presentation	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, 2019 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 10 and 16. 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, 2018. The results of operations for the three and nine months ended March 31, 2019 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year. Certain reclassifications have been made to the prior period’s financial statements to conform to the current presentation.

In addition, for our fiscal year ending June 30, 2019 and the interim reporting periods therein, the Company is required to disclose the amount by which each financial statement line item was affected by the new standard. The Company’s comparative information, for prior periods presented before July 1, 2018, has not been restated and continues to be reported under ASC 605. The impact of adoption on our consolidated balance sheet is as follows (in thousands): June 30, 2018 As Reported Under ASC 605 Adjustments Due to ASC 606 July 1, 2018 Balance Under ASC 606 Assets: Accounts receivable, net $ 806,871 $ 20,454 $ 827,325 Prepaid expenses and other current assets 58,126 2,342 60,468 Other long-term assets 39,175 3,923 43,098 Liabilities and Shareholders' Equity: Other accrued expenses and current liabilities 150,602 2,212 152,814 Deferred income taxes 200,880 6,639 207,519 Other long-term liabilities 85,187 98 85,285 Retained earnings 2,126,790 17,770 2,144,560 ASC 606 changed the pattern of revenue recognition for some of our contracts with customers. For our award and incentive fee contracts, we recognize an estimated amount of variable consideration throughout the performance period rather than defer recognition of the relevant portion of fee until customer notification of the amount earned. Some of our fixed price services-type contracts in which revenue was previously recognized on a straight-line basis over the performance period converted to recognition of revenue using a cost-to-cost input method to measure our progress towards the complete satisfaction of the performance obligation. The cumulative effect of these changes in the pattern of revenue recognition resulted in an increase to accounts receivable with an offset to retained earnings. In addition, ASC 606 changed the timing of revenue recognition for license renewal performance obligations. Under prior GAAP, license renewals were generally recognized in the period the renewal contract was executed. However, upon adoption of ASC 606, revenue for a license renewal may not be recognized until the start of the term of the renewal. The cumulative effect of this change resulted in an increase to contract liabilities with an offset to retained earnings. The adoption of ASC 606 did not have a material impact on the Company’s revenue recognition for cost-plus-fee, fixed price/level-of-effort, time-and-materials (T&M), fixed price contracts previously recognized under ASC 605-35, and fixed price product revenue arrangements. Under ASC 340-40, the Company capitalizes certain costs to fulfill and obtain a contract. The cumulative effect of this change resulted in an increase to contract assets with an offset to retained earnings. These capitalized costs are amortized over the period of contract performance as revenue is recognized from the transfer of goods or services and the underlying performance obligation is satisfied. The table below presents the impact of adoption of ASC 606 on our consolidated statement of operations for the three and nine months ended March 31, 2019 (in thousands, except per share data): Three Months Ended Nine Months Ended March 31, 2019 March 31, 2019 As Adjusted Under ASC 605 Effect of ASC 606 As Reported Under ASC 606 As Adjusted Under ASC 605 Effect of ASC 606 As Reported Under ASC 606 Revenue $ 1,263,174 $ 1,784 $ 1,264,958 $ 3,599,511 $ 12,952 $ 3,612,463 Costs of revenue: Direct costs 824,024 — 824,024 2,397,633 — 2,397,633 Indirect costs and selling expenses 324,597 231 324,828 860,294 (1,032 ) 859,262 Depreciation and amortization 21,198 — 21,198 58,797 — 58,797 Total costs of revenue 1,169,819 231 1,170,050 3,316,724 (1,032 ) 3,315,692 Income from operations 93,355 1,553 94,908 282,787 13,984 296,771 Interest expense and other, net 13,466 — 13,466 31,773 — 31,773 Income before taxes 79,889 1,553 81,442 251,014 13,984 264,998 Income tax expense 12,875 422 13,297 45,820 3,604 49,424 Net income $ 67,014 $ 1,131 $ 68,145 $ 205,194 $ 10,380 $ 215,574 Basic earnings per share $ 2.70 $ 0.05 $ 2.74 $ 8.27 $ 0.42 $ 8.69 Diluted earnings per share $ 2.64 $ 0.04 $ 2.69 $ 8.09 $ 0.41 $ 8.50 For the three months ended March 31, 2019, the effect of ASC 606 was primarily related to certain fixed price services-type contracts in which revenue was previously recognized on a straight-line basis that converted to a cost-to-cost input method to measure the Company’s progress towards the complete satisfaction of the performance obligation. For the nine months ended March 31, 2019, the effect of ASC 606 was primarily related to the timing of award and incentive fee revenue recognition.

Revenue Recognition	Revenue Recognition The Company generates almost all of our revenue from three different types of contractual arrangements with the U.S. government: cost-plus-fee, time-and-materials (T&M), and fixed-price contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services. We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and it is probable that we will collect substantially all of the consideration. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires significant professional judgment as it may impact the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation. When determining the total transaction price, the Company identifies both fixed and variable consideration elements within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenue. Throughout the performance period, we recognize as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. Our estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which we can calculate the final amount of award or incentive fee earned - based on the receipt of the customer’s final performance score or determining that more objective, contractually-defined criteria have been fully satisfied - the Company will adjust our cumulative revenue recognized to date on the contract. This adjustment to revenue will be disclosed as the amount of revenue recognized in the current period for a previously satisfied performance obligation. We generally recognize revenue over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on our services-type revenue arrangements. This continuous transfer of control for our U.S. government contracts is supported by the unilateral right of our customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For our services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. We use a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including: costs incurred, labor hours expended, and time-elapsed measures for our fixed-price stand ready obligations. For certain contracts, primarily our cost-plus and T&M services-type revenue arrangements, we apply the right-to-invoice practical expedient in which revenue is recognized in direct proportion to our present right to consideration for progress towards the complete satisfaction of the performance obligation. When a performance obligation has a significant degree of interrelation or interdependence between one month’s deliverables and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion methodology. For these revenue arrangements, substantially all revenue is recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. 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. Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. When a contract modification changes the scope or price and the additional performance obligations are at their standalone selling price, the original contract is terminated and the Company accounts for the change prospectively when the new goods or services to be transferred are distinct from those already provided. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenue based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation. Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and our knowledge of available funding for the contract or program.
Contract Assets	Contract Assets Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables. In addition, the costs to fulfill a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g. ramp up costs at the beginning of the period of performance) may be capitalized when expenses are incurred prior to satisfying a performance obligation. 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. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception. Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value.
Contract Liabilities	Contract Liabilities Contract liabilities include advance payments received from the customer in excess of revenue that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenue as the performance obligation is satisfied.
Remaining Performance Obligations	Remaining Performance Obligations The Company’s remaining performance obligations balance represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts as of period end. The remaining performance obligations balance excludes unexercised contract option years and task orders that may be issued underneath an Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle. 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 our remaining performance obligations 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.
