Organization, Consolidation and Presentation of Financial Statements [Abstract]
Subsequent Events	Subsequent Events - The Company evaluated subsequent events, if any, that would require an adjustment to the Company’s condensed consolidated financial statements or require disclosure in the notes to the condensed consolidated financial statements through the date of issuance of the condensed consolidated financial statements. Where applicable, the notes to these condensed consolidated financial statements have been updated to discuss all significant subsequent events which have occurred.
Basis of Presentation	The accompanying condensed consolidated financial statements, prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”), include the accounts of the Company and its majority-owned direct and indirect subsidiaries. All intercompany accounts and transactions have been eliminated. Certain notes and other information have been condensed or omitted from the condensed consolidated financial statements. Therefore, these condensed consolidated financial statements should be read in conjunction with the December 31, 2023 audited consolidated financial statements and notes thereto included in CVR Energy’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). Our condensed consolidated financial statements include the consolidated results of CVR Partners, which is defined as a variable interest entity (“VIE”). As the 100% owner of the general partner of CVR Partners, the Company has the sole ability to direct the activities that most significantly impact the economic performance of CVR Partners and is considered the primary beneficiary. In the opinion of the Company’s management, the accompanying condensed consolidated financial statements reflect all adjustments that are necessary for fair presentation of the financial position and results of operations of the Company for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. The condensed consolidated financial statements are prepared in conformity with GAAP, which requires management to make certain estimates and assumptions that affect the reported amounts and disclosure of 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. Results of operations and cash flows for the interim periods presented are not necessarily indicative of the results that will be realized for the year ending December 31, 2024 or any other interim or annual period.
Recent Accounting Pronouncements - Accounting Standards Issued But Not Yet Implemented	Recent Accounting Pronouncements - Accounting Standards Issued But Not Yet Implemented In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures that reflect how operations and related tax risks, as well as how tax planning and operational opportunities, affect the tax rate and prospects for future cash flows. This standard is effective for the Company’s annual period beginning January 1, 2025 with early adoption permitted. The Company is evaluating the effects of adopting this new accounting guidance on its disclosures but does not currently expect adoption will have a material impact on the Company’s consolidated financial statements. The Company does not intend to early adopt this ASU. In November 2023, FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures, which includes requirements for more robust disclosures of significant segment expenses and measures of a segment’s profit and loss used in assessing performance. This standard is effective for the Company’s annual period beginning January 1, 2024 and interim periods beginning January 1, 2025 and should be applied retrospectively to all comparative periods. Early adoption is permitted. The Company is still evaluating the effects of adopting this new accounting guidance on its disclosures.
