Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments necessary to present fairly the financial position as of July 31, 2026 and April 30, 2026, the results of operations for the three months ended July 31, 2026 and 2025, and shareholders' equity and cash flows for the three months ended July 31, 2026 and 2025. Although management believes that the disclosures are adequate to make the information presented not misleading, it is suggested that these interim condensed consolidated financial statements be read in conjunction with the Company’s most recent audited financial statements and notes thereto. Additionally, see the most recent audited financial statements for our consideration of new accounting pronouncements issued prior to this fiscal year. During the quarter, the Company elected to early adopt ASU 2026‑02, Environmental Credits and Environmental Credit Obligations (Topic 818). The standard establishes guidance for the recognition, measurement, presentation, and disclosure of environmental credits and environmental credit obligations. The new standard impacts the Company's accounting for renewable identification numbers ("RINs"). The Company adopted the guidance on a retrospective basis effective May 1, 2026. The effect of applying the guidance to prior-period financial statements was not material and no cumulative-effect adjustment to the opening balance of retained earnings was required. Refer to Note 3 for the required disclosures and details of the new accounting policy.

Revenue from Contract with Customer [Abstract]
Revenue and Cost of Goods Sold	Revenue and Cost of Goods Sold The Company recognizes retail sales of prepared food and dispensed beverage, grocery and general merchandise, fuel and other revenue at the time of the sale to the guest. Sales taxes collected from guests and remitted to the government are recorded on a net basis in the condensed consolidated statements of income. A portion of revenue from sales that include points under our Casey’s Rewards program is deferred. The deferred portion of the sale represents the value of the estimated future redemption of the points. The amounts related to points are deferred until their redemption or expiration. Revenue related to the points issued is expected to be recognized less than one year from the original sale to the guest. As of July 31, 2026 and April 30, 2026, the Company recognized a contract liability of $74,734 and $72,695, respectively, primarily related to the Casey's Rewards program, which is included in accrued expenses and current portion of operating lease liabilities on the condensed consolidated balance sheets. The Company often receives vendor allowances on the basis of quantitative contract terms that vary by product and vendor or directly on the basis of purchases made. Vendor allowances include rebates and other funds received from vendors to promote their products. These amounts are recognized in the period earned based on the applicable rebate agreement. Reimbursements of an operating expense (e.g., advertising) are recorded as reductions of the related expense. RINs are assigned to gallons of renewable fuels produced and are used to track compliance with the U.S. Renewable Fuel Standard ("RFS"). At times, we purchase fuel components (ethanol, gasoline, biodiesel or diesel) and blend those components into a finished product. This process enables the Company to detach the RIN assigned to each gallon of ethanol or biodiesel and sell it in a transaction separate from the eventual sale of the related biofuel. Since we are not an obligated party under the RFS, the Company sells all RINs through exchange transactions. As a result, the Company has recognized the RINs as noncompliance environmental credits. The Company has elected to utilize the accounting policy election to measure these noncompliance environmental credits at fair value as of the reporting date. The fair value of RINs recognized are based upon quoted market prices for RINs in active markets, which are considered Level 1 inputs within the fair value hierarchy, and are recorded on the condensed consolidated balance sheets within prepaid and other current assets. As of July 31, 2026 and April 30, 2026, outstanding balances were immaterial to the financial statements. When RINs are sold or adjusted to fair value, the gains or losses recognized are recognized through cost of goods sold within the condensed consolidated statements of income. The Company did not recognize any impairment losses on these assets for the three months ended July 31, 2026, and 2025.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Compensation Related Costs and Share Based Payments

3 Months Ended

Share-Based Payment Arrangement [Abstract]

Compensation Related Costs and Share-Based Payments

The 2025 Stock Incentive Plan (the “2025 Plan”) was approved by the Company’s shareholders on September 3, 2025, at the Company’s annual shareholders meeting (the “2025 Plan Effective Date”). There were 1,650,000 shares available for issuance under the 2025 Plan as of the 2025 Plan Effective Date. The 2025 Plan replaces the 2018 Stock Incentive Plan (the "2018 Plan"), under which no new awards were allowed to be granted as of the 2025 Plan Effective Date. Outstanding awards under the 2018 Plan continue to be governed by the terms thereof and the award agreements made pursuant thereto, including any such terms that are intended to survive the termination of the 2018 Plan or the settlement of such awards. Shares subject to awards under the 2018 Plan that expire, are forfeited, cancelled, or settled in cash will be added back to the shares available for issuance under the 2025 Plan. Awards under the 2025 Plan may take the form of stock options, stock appreciation rights, restricted stock, restricted stock units and other equity-based and equity-related awards, each of which, upon issuance, is counted as one share against the 2025 Plan share reserve. At July 31, 2026, there were 1,593,826 shares that remain available for grant under the 2025 Plan.

We account for share-based compensation by estimating the grant date fair value of time-based and performance-based restricted stock unit awards using the closing price of our common stock on the applicable grant date, or the date on which performance goals for performance-based units are established, if after the grant date. Forfeitures are recognized as they occur.

The time-based awards most commonly vest ratably over a three-year period commencing on the first anniversary of the grant date. Certain awards include performance and market conditions. Performance-based awards are primarily based on either the achievement of a three-year average return on invested capital (ROIC) or three-year cumulative earnings before interest, income taxes, and depreciation and amortization (EBITDA). For these awards, share-based compensation expense is estimated based on the probable outcome of shares to be awarded adjusted as necessary at each reporting period. Additionally, if the Company's relative total shareholder return over the performance period is in the bottom or top quartile of the companies comprising the S&P 500, the performance-based shares included will be adjusted downward by 25%, or upward by 25%, respectively (the "TSR Modifier"). The fair value of awards with the TSR Modifier is determined using a Monte Carlo simulation as of the date of the grant. For the market-based portion of these awards, the share-based compensation expense will not be adjusted should the target awards vary from actual awards.

We recognize these amounts as an operating expense in our condensed consolidated statements of income ratably over the requisite service period using the straight-line method, as adjusted for certain retirement provisions, and updated estimates of shares to be issued under performance-based awards. All awards have been granted at no cost to the grantee.

Total share-based compensation costs recorded for employees and non-employee directors for the three months ended July 31, 2026 and 2025 were $16,930 and $15,221, respectively, related entirely to restricted stock unit awards. As of July 31, 2026, there was $86,554 of unrecognized compensation costs related to restricted stock units which are expected to be recognized through fiscal 2030, with a weighted average remaining term of 1.5 years. The fair value of restricted stock unit awards vested during the three months ended July 31, 2026 was $189,707 as of the applicable vest date.

Segment Reporting

Segment Reporting [Abstract]

Segment Reporting

As of July 31, 2026, we operated 2,959 stores in 19 states. Our convenience stores offer a broad selection of merchandise, fuel and other products and services designed to appeal to the convenience needs of our guests. We manage the business on the basis of one operating segment and therefore, have only one reportable segment. Our stores sell similar products and services, use similar processes to sell those products and services, and sell their products and services to similar classes of guests. We make specific disclosures concerning the three broad categories of prepared food and dispensed beverage, grocery and general merchandise, and fuel because it allows us to more effectively discuss trends and operational initiatives within our business and industry. Although we can separate revenues and cost of goods sold within these categories (and further sub-categories), the operating expenses associated with operating a store that sells these products are not separable by these three categories.

Casey’s chief operating decision maker (“CODM”) is the President and Chief Executive Officer. The CODM assesses performance for the segment and decides how to allocate resources and capital based on profitability metrics, such as net income, that is reported on the condensed consolidated statements of income. The CODM considers actual-to-forecast variances on a monthly, quarterly and annual basis for this profit measure when making decisions about resource allocation and assessing company performance. Total asset information by segment is not regularly provided to our CODM or utilized for purposes of assessing performance or allocating resources and, as a result, such information has not been presented below.

The following table provides information on revenue, significant expenses, and net income related to the single reportable segment:

Commitments and Contingencies	Jul. 31, 2026
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time we may be involved in legal or administrative proceedings or investigations arising from the conduct of our business operations, including, but not limited to, contractual or other general business disputes; employment, personnel, or accessibility matters; personal injury and property damage claims; claims by federal, state, and local regulatory authorities relating to the sale of products pursuant to licenses and permits issued by those authorities; and, other claims or proceedings. Claims for damages in those actions may be substantial. While the outcome of such litigation, proceedings, investigations, or claims is never certain, it is our opinion, after taking into consideration legal counsel’s assessment and the availability of insurance proceeds and other collateral sources to cover potential losses, that the ultimate disposition of such matters currently pending or threatened, individually or cumulatively, will not have a material adverse effect on our consolidated financial position and results of operations. The Company is named as a defendant in two lawsuits alleging that it misclassified its Store Managers as exempt employees under the Fair Labor Standards Act (FLSA) - White (f/k/a McColley) v. Casey’s General Stores, Inc. in the United States District Court for the Northern District of Indiana and Kessler v. Casey’s Marketing Company, et al. in the Southern District of Illinois. During the prior year, the parties agreed to a settlement of all claims in both matters for an amount that is not material to the Company's condensed consolidated financial statements. The settlement(s) were approved by the applicable court during the quarter, and the parties, with the assistance of a third-party settlement administrator, are in the process of distributing settlement funds. The Company continues to maintain that its Store Managers are properly classified as exempt employees under the FLSA and does not admit any wrongdoing as a result of the settlement.

Long-Term Debt and Fair Value Disclosure [Abstract]
Long-term Debt and Finance Lease Obligations, Lines of Credit and Fair Value Disclosure	Long-Term Debt and Finance Lease Obligations, Lines of Credit and Fair Value Disclosure The fair value of the Company’s long-term debt (including current maturities) is estimated based on the current rates offered to the Company for debt of the same or similar issuances which are considered Level 2 inputs within the fair value hierarchy. The fair value of the Company’s long-term debt was approximately $2,219,000 and $2,226,000 at July 31, 2026 and April 30, 2026, respectively. The fair value calculated excludes finance lease obligations of $113,808 and $115,197 outstanding at July 31, 2026 and April 30, 2026, respectively, which are included with long-term debt on the condensed consolidated balance sheets. Interest, net on the condensed consolidated statements of income is net of interest income of $3,548 for the three months ended July 31, 2026, and $2,977 for the three months ended July 31, 2025. Interest, net is also net of interest capitalized of $1,091 for the three months ended July 31, 2026, and $495 for the three months ended July 31, 2025. Revolving Facility The Company has a credit agreement that provides for an $850,000 unsecured revolving credit facility (“Revolving Facility”), which matures on April 21, 2028. Amounts borrowed under the Revolving Facility, bear interest at variable rates based upon, at the Company’s option, either: (a) either Term SOFR or Daily Simple SOFR, in each case plus 0.10% (with a floor of 0.00%) for the interest period in effect, plus an applicable margin ranging from 1.10% to 1.70% or (b) an alternate base rate, which generally equals the highest of (i) the prime commercial lending rate announced by the Administrative Agent as its “prime rate”, (ii) the federal funds rate plus 1/2 of 1.00%, and (iii) Adjusted Daily Simple SOFR plus 1.00%, each plus an applicable margin ranging from 0.10% to 0.70% and each with a floor of 1.00%. The applicable margins and facility fee, in each case, are dependent upon the Company’s quarterly Consolidated Leverage Ratio, as defined in the credit agreement. The Company had $42,625 and $0 outstanding under the Revolving Facility at July 31, 2026 and April 30, 2026, respectively, which is included with long-term debt on the condensed consolidated balance sheets. Bank Line The Company has an additional unsecured bank line of credit (the "Bank Line") with availability of up to $50,000. The Bank Line bears interest at a variable rate subject to change from time to time based on changes in an independent index referred to in the Bank Line as the Federal Funds Offered Rate. There was $0 outstanding under the Bank Line at July 31, 2026 and April 30, 2026. The Bank Line is due upon demand.
