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. generally accepted accounting principles 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 revenues 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, 2023 and April 30, 2023, the results of operations, for the three months ended July 31, 2023 and 2022, and shareholders' equity and cash flows for the three months ended July 31, 2023 and 2022. 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 Form 10-K for the year ended April 30, 2023 for our consideration of new accounting pronouncements.

Revenue from Contract with Customer [Abstract]
Revenue and Cost of Goods Sold	Revenue and Cost of Goods Sold The Company recognizes retail sales of fuel, grocery and general merchandise, prepared food and dispensed beverage 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 a redeemable digital box top coupon or 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 digital box top coupon or points. The amounts related to digital box top coupons and points are deferred until their redemption or expiration. Revenue related to the digital box top coupons and points issued is expected to be recognized less than one year from the original sale to the guest. As of July 31, 2023 and April 30, 2023, the Company recognized a contract liability of $52,935 and $55,561, respectively, related to the outstanding digital box top coupons and Casey's Rewards points, which is included in accrued expenses on the condensed consolidated balance sheets. During the quarter ended July 31, 2023, the Company recorded a reduction of the liability of $4,800 due to planned changes in the digital box top program. Gift card related revenue is recognized as the gift cards are used by the guest. Gift card breakage revenue is recognized based on the estimated gift card breakage rate over the pro rata usage of the card. As of July 31, 2023 and April 30, 2023, the Company recognized a liability of $16,563 and $17,463, respectively, related to outstanding gift cards, which is included in accrued expenses on the condensed consolidated balance sheets.

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. The fair value of the Company’s long-term debt was approximately $1,396,000 and $1,437,000 at July 31, 2023 and April 30, 2023, respectively. The fair value calculated excludes finance lease obligations of $100,908 and $95,072 outstanding at July 31, 2023 and April 30, 2023, respectively, which are grouped 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 $3,576, and $0 for the three months ended July 31, 2023 and 2022, respectively. Interest, net is also net of interest capitalized of $794, and $581 for the three months ended July 31, 2023 and 2022, respectively. Revolving Facility The Company has a credit agreement that provides for an $850,000 unsecured revolving credit facility (“Revolving Facility”). Amounts borrowed under the Revolving Facility bear interest at variable rates based upon, at the Company’s option: (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 Revolving Facility carries a facility fee of 0.15% to 0.30% per annum. 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 $0 outstanding under the Revolving Facility at July 31, 2023 and April 30, 2023. Bank Line

Share-Based Payment Arrangement [Abstract]
Compensation Related Costs and Share Based Payments	Compensation Related Costs and Share Based Payments The 2018 Stock Incentive Plan (the “2018 Plan”) was approved by the Company's shareholders on September 5, 2018. Awards under the 2018 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 share issued pursuant to a stock option and each share with respect to which a stock-settled stock appreciation right is exercised (regardless of the number of shares actually delivered) is counted as one share against the maximum limit under the 2018 Plan, and each share issued pursuant to an award of restricted stock or restricted stock units is counted as two shares against the maximum limit. Restricted stock is transferred immediately upon grant (and may be subject to a holding period), whereas restricted stock units have a vesting period that must expire, and in some cases performance or market conditions that must be satisfied before the stock is transferred. At July 31, 2023, there were 1,143,924 shares available for grant under the 2018 Plan. We account for stock-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. The performance-based awards represent a “target” amount; the final amount earned is based on the satisfaction of certain performance measures over a three-year performance period and will range from 0% to 200% of “target." 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 fair value of these awards is determined using a Monte Carlo simulation as of the date of the grant. For market-based awards, the stock-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. Information concerning the unvested restricted stock units under the 2018 Plan is presented in the following table: Weighted-Average Grant Date Fair Shares Value per Share Unvested at April 30, 2023 550,840 $ 212 Granted 129,879 236 Vested (207,043) 194 Forfeited (6,044) 224 Unvested at July 31, 2023 467,632 $ 227

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 a lawsuit filed in the United States District Court for the Northern District of Indiana, titled McColley v. Casey’s General Stores, Inc. , in which the plaintiff alleges that the Company misclassified its Store Managers as exempt employees under the Fair Labor Standards Act (FLSA). The complaint seeks unpaid wages, liquidated damages and attorneys’ fees for the plaintiff and all similarly situated Store Managers who worked at the Company from February 16, 2015 to the present. On March 31, 2021, the Court granted conditional certification, and to-date, approximately 1,400 current and/or former Store Managers (representing less than 1/4 of those eligible) remain opted-in to participate in the lawsuit. The Company believes that adequate provisions have been made for probable losses related to this matter, and that those, and the reasonably possible losses in excess of amounts accrued, where such range of loss can be estimated, are not material to the Company’s financial position, results of operations or cash flows. The Company believes that its Store Managers are properly classified as exempt employees under the FLSA and it intends to continue to vigorously defend the matter. We have entered into various purchase agreements related to our fuel supply, which include varying volume commitments. Prices included in the purchase agreements are indexed to market prices. While volume commitments are included in the contracts, we do not have a history of incurring material penalties related to these provisions. These contracts are not accounted for as derivatives as they meet the normal purchases exclusion under derivative accounting.

Unrecognized Tax Benefits

Income Tax Disclosure [Abstract]
Unrecognized Tax Benefits	Unrecognized Tax Benefits The total amount of gross unrecognized tax benefits was $11,980 and $10,957 at July 31, 2023 and April 30, 2023, respectively. If this unrecognized tax benefit were ultimately recognized, $9,465 is the amount that would impact our effective tax rate. The total amount of accrued interest and penalties for such unrecognized tax benefits was $445 at July 31, 2023, and $386 at April 30, 2023. Net interest and penalties included in income tax expense for the three months ended July 31, 2023 and 2022, was a net expense of $59 and $53, respectively. A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. The Company has no ongoing federal or state income tax examinations. At this time, the Company’s best estimate of the reasonably possible change in the amount of the gross unrecognized tax benefits is a decrease of $2,500 during the next twelve months mainly due to the expiration of certain statute of limitations. The federal statute of limitations remains open for the tax years 2019 and forward. Tax years 2016 and forward are subject to audit by state tax authorities depending on open statute of limitations waivers and the tax code of each state.

Segment Reporting [Abstract]
Segment Reporting	Segment ReportingAs of July 31, 2023, we operated 2,536 stores in 16 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 fuel, grocery and general merchandise, and prepared food and dispensed beverage 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.

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. generally accepted accounting principles 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 revenues and expenses during the reporting period.

Revenue Recognition	The Company recognizes retail sales of fuel, grocery and general merchandise, prepared food and dispensed beverage 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 a redeemable digital box top coupon or 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 digital box top coupon or points. The amounts related to digital box top coupons and points are deferred until their redemption or expiration. Revenue related to the digital box top coupons and points issued is expected to be recognized less than one year from the original sale to the guest. As of July 31, 2023 and April 30, 2023, the Company recognized a contract liability of $52,935 and $55,561, respectively, related to the outstanding digital box top coupons and Casey's Rewards points, which is included in accrued expenses on the condensed consolidated balance sheets. During the quarter ended July 31, 2023, the Company recorded a reduction of the liability of $4,800 due to planned changes in the digital box top program. Gift card related revenue is recognized as the gift cards are used by the guest. Gift card breakage revenue is recognized based on the estimated gift card breakage rate over the pro rata usage of the card. As of July 31, 2023 and April 30, 2023, the Company recognized a liability of $16,563 and $17,463, respectively, related to outstanding gift cards, which is included in accrued expenses on the condensed consolidated balance sheets.
