Accounting Policies [Abstract]
Income Taxes	Rithm Capital has elected and intends to qualify to be taxed as a REIT for U.S. federal income tax purposes. As such, Rithm Capital will generally not be subject to U.S. federal corporate income tax on that portion of its net income that is distributed to stockholders if it distributes at least 90% of its REIT taxable income to its stockholders by prescribed dates and complies with various other requirements. See Note 23, Income Taxes, for additional information regarding Rithm Capital’s taxable REIT subsidiaries.
Segment Reporting	As of March 31, 2023, Rithm Capital conducted its business through the following segments: (i) Origination, (ii) Servicing, (iii) MSR Related Investments, (iv) Residential Securities, Properties and Loans, (v) Consumer Loans, (vi) Mortgage Loans Receivable and (vii) Corporate.
Interim Financial Statements	Interim Financial Statements — The accompanying Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP’’ or “U.S. GAAP”). In the opinion of management, all adjustments considered necessary for a fair presentation of Rithm Capital’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The Consolidated Financial Statements include the accounts of Rithm Capital and its consolidated subsidiaries. All significant intercompany transactions and balances have been eliminated. Rithm Capital consolidates those entities in which it has control over significant operating, financing and investing decisions of the entity, as well as those entities deemed to be VIEs in which Rithm Capital is determined to be the primary beneficiary. For entities over which Rithm Capital exercises significant influence, but which do not meet the requirements for consolidation, Rithm Capital uses the equity method of accounting whereby it records its share of the underlying income of such entities. Distributions from equity method investees are classified in the Consolidated Statements of Cash Flows based on the cumulative earnings approach, where all distributions up to cumulative earnings are classified as distributions of earnings.
Reclassifications	Reclassifications — Certain prior period amounts in Rithm Capital’s Consolidated Financial Statements and respective notes have been reclassified to be consistent with the current period presentation. Such reclassifications had no impact on net income, total assets, total liabilities, or stockholders’ equity.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets — The Company reviews long-lived assets for impairment when events or changes in circumstances indicate the carrying value of these assets may exceed their current fair values. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. No impairment charges were recognized for the three months ended March 31, 2023. In the future, if events or market conditions affect the estimated fair value to the extent that a long-lived asset is impaired, the Company will adjust the carrying value of these long-lived assets in the period in which the impairment occurs.
Risks and Uncertainties	Risks and Uncertainties — In the normal course of business, Rithm Capital encounters primarily two significant types of economic risk: credit and market. Credit risk is the risk of default on Rithm Capital’s investments that results from a borrower’s or counterparty’s inability or unwillingness to make contractually required payments. Market risk reflects changes in the value of investments due to changes in prepayment rates, interest rates, spreads or other market factors, including risks that impact the value of the collateral underlying Rithm Capital’s investments. Taking into consideration these risks along with estimated prepayments, financings, collateral values, payment histories and other information, Rithm Capital believes that the carrying values of its investments are reasonable. Furthermore, for each of the periods presented, a significant portion of Rithm Capital’s assets are dependent on its servicers’ and subservicers’ ability to perform their obligations servicing the residential mortgage loans underlying Rithm Capital’s Excess MSRs, MSRs, MSR financing receivables, servicer advance investments, Non-Agency RMBS and loans. If a servicer is terminated, Rithm Capital’s right to receive its portion of the cash flows related to interests in servicing related assets may also be terminated. The mortgage and financial sectors are operating in a challenging and uncertain economic environment. Financial and real estate companies continue to be affected by, among other things, market volatility, rapidly rising interest rates and inflationary pressures. Should macroeconomic conditions continue to worsen, there is no assurance that such conditions will not result in an overall decline in the fair value of many assets, including those in which the Company invests, and potential impairment of the carrying value of goodwill or other intangible assets. The ultimate duration and impact of the current economic environment remain uncertain. Rithm Capital is subject to significant tax risks. If Rithm Capital were to fail to qualify as a REIT in any taxable year, Rithm Capital would be subject to U.S. federal corporate income tax (including any applicable alternative minimum tax), which could be material. Unless entitled to relief under certain statutory provisions, Rithm Capital would also be disqualified from treatment as a REIT for the four taxable years following the year during which qualification is lost.
Use of Estimates	Use of Estimates — 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, the 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements — In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The standard was issued to ease the accounting effects of reform to the London Interbank Offered Rate (“LIBOR”) and other reference rates. The standard provides optional expedients and exceptions for applying GAAP to debt, derivatives and other contracts affected by reference rate reform. The standard was effective for all entities as of March 12, 2020 through December 31, 2022 and was able to be elected over time as reference rate reform activities occur. Additionally, in December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. The standard defers the expiration date of ASC 848 from December 31, 2022 to December 31, 2024. ASU 2022-06 became effective upon issuance. The Company is continuing to assess the impact of the LIBOR transition and does not expect the transition or the adoption of the standard to have a material impact on the Consolidated Financial Statements. The Company’s primary exposure to LIBOR includes certain financing arrangements, interest rate swaps and the 7.50% Series A, 7.125% Series B, and 6.375% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock. The Company's financing arrangements either have provisions in place that provide for an alternative to LIBOR upon its phase-out or contain maturities of one year or less and therefore would mature prior to the phase out of LIBOR in June 2023. In addition, the Company has amended terms of certain financing arrangements, where necessary, to transition or direct the transition to an alternative benchmark. Interest rate swaps are expected to experience an orderly market transition prior to the cessation of LIBOR, and the Company has begun transitioning its interest rate swap portfolio away from LIBOR benchmarks. The Company does not currently intend to amend the 7.50% Series A, 7.125% Series B, or 6.375% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock to change the existing USD-LIBOR cessation fallback language. In March 2022, the FASB issued ASU 2022-01, Derivative and Hedging (Topic 815): Fair Value Hedging–Portfolio Layer Method. The standard clarifies the accounting and promotes consistency in reporting for hedges where the portfolio layer method is applied. The new standard is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company’s adoption of the new standard did not have a material effect on its Consolidated Financial Statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The standard clarifies that a contractual restriction on the sale of an equity security is not considered in measuring the security’s fair value. The standard also requires certain disclosures for equity securities that are subject to contractual restrictions. The new standard is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material effect on its Consolidated Financial Statements.
