Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Credit Agreement On December 21, 2021, the Company entered into a Second Amended and Restated Credit Agreement by and among the Company, certain subsidiaries of the Company party thereto, the lenders party thereto, and Bank of America, N.A., as administrative agent (the “Second Amended and Restated Credit Agreement”). The Second Amended and Restated Credit Agreement amends and restates certain terms of the First Amended and Restated Credit Agreement, dated as of July 21, 2020, by and among the Company, the lenders party thereto, and Bank of America, N.A., as administrative agent (as successor in interest to Wells Fargo Bank, National Association) (the “Existing Credit Agreement”). The Second Amended and Restated Credit Agreement provides for, among other things, (a) an increase in the secured revolving credit commitments by $200.0 million, bringing the aggregate principal amount of the revolving credit commitments under the Second Amended and Restated Credit Agreement (the “Revolving Loan Facility”) to $1,250.0 million, (b) an increase in the letter of credit sublimit from $60.0 million to $100.0 million, (c) addition of Copart UK Limited, CPRT GmbH and Copart Autos España, S.L.U., each a wholly-owned direct or indirect foreign subsidiary of the Company, as borrowers, (d) addition of the ability to borrow under the Second and Amended and Restated Credit Agreement in certain foreign currencies including Pounds Sterling, Euro and Canadian Dollars, (e) extension of the maturity date of the revolving credit facility under the Existing Credit Agreement from July 21, 2023 to December 21, 2026, (f) replacing the LIBOR interest rate applicable to U.S. Dollar denominated borrowings with a SOFR-based interest rate, and (g) changing the pricing levels with respect to the revolving loans as further described below. The Second and Amended and Restated Credit Agreement provides for a revolving loan facility (the “Revolving Loan Facility”) of $1,250.0 million maturing on December 21, 2026 (including up to $550.0 million equivalent of borrowings in Pounds Sterling, European Union euro and Canadian dollars) with a $150.0 million equivalent sub-facility available to CPRT GmbH, a $150.0 million equivalent sub-facility available to Copart Autos España, S.L.U. and a $250.0 million equivalent sub-facility available to Copart UK Limited. The proceeds may be used for general corporate purposes, including working capital and capital expenditures, potential share repurchases, acquisitions, or other investments relating to the Company’s expansion strategies in domestic and international markets. Borrowings under the Second Amended and Restated Credit Agreement bear interest based on, at our option, either (1) the applicable fixed rate plus 1.00% to 1.75% or (2) the daily rate plus 0.0% to 0.75%, in each case, depending on the Company’s consolidated total net leverage ratio. Additionally, the unused revolving commitments under the Second Amended and Restated Credit Agreement are subject to the payment of a customary commitment fee at a range of 0.175% to 0.275%, depending on the Company’s consolidated total net leverage ratio. The applicable fixed rates described above with respect to borrowings denominated in (1) U.S. Dollars is SOFR plus certain “spread adjustments” described in the Second Amended and Restated Credit Agreement, (2) Pounds Sterling is SONIA plus certain “spread adjustments” described in the Second Amended and Restated Credit Agreement, (3) the European Union euro is EURIBOR, and (4) Canadian dollars is CDOR. The Company had no outstanding borrowings under the Revolving Loan Facility as of July 31, 2025 and July 31, 2024. The Company’s obligations under the Second Amended and Restated Credit Agreement are guaranteed by certain of the Company’s domestic subsidiaries meeting materiality thresholds set forth in the Second Amended and Restated Credit Agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the assets of the subsidiary guarantors pursuant to a Security Documents Confirmation Agreement as part of the Second Amended and Restated Credit Agreement. The Second Amended and Restated Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company’s and its subsidiaries’ ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into transactions with affiliates, pay dividends, or make distributions on and repurchase stock, in each case subject to certain exceptions. The Company is also required to maintain compliance, measured at the end of each fiscal quarter, with a consolidated total net leverage ratio and a consolidated interest coverage ratio. The Second Amended and Restated Credit Agreement contains no restrictions on the payment of dividends and other restricted payments, as defined, as long as (1) the consolidated total net leverage ratio, as defined, both before and after giving effect to any such dividend or restricted payment on a pro forma basis, is less than 3.25:1, in an unlimited amount, (2) if clause (1) is not available, so long as the consolidated total net leverage ratio both before and after giving effect to any such dividend on a pro forma basis is less than 3.50:1, in an aggregate amount not to exceed the available amount, as defined, and (3) if clauses (1) and (2) are not available, in an aggregate amount not to exceed $50.0 million; provided, that, minimum liquidity, as defined, shall be not less than $75.0 million both before and after giving effect to any such dividend or restricted payment. As of July 31, 2025, the consolidated total net leverage ratio was (2.35):1. Minimum liquidity requirement as of July 31, 2025 was $6.0 billion. Accordingly, the Company does not believe that the provisions of the Second Amended and Restated Credit Agreement represent a significant restriction to its ability to pay dividends or to the successful future operations of the business. The Company has not paid a cash dividend since becoming a public company in 1994. The Company was in compliance with all covenants related to the Second Amended and Restated Credit Agreement as of July 31, 2025. Related to execution of the Second Amended and Restated Credit Agreement, the Company incurred $2.7 million in costs, which were capitalized as debt issuance fees. The debt discount is amortized to interest expense over the term of the respective debt instruments and is included in other assets on the consolidated balance sheet.
