US interest rules
This source-backed guide covers US interest SOL (28 U.S.C. § 1961). It certifies only the quoted source-backed rules below; related interest categories remain outside this page unless they are expressly listed in the receipt.
Federal post-judgment interest rate
Post-judgment interest on any federal civil money judgment runs at the weekly average 1-year constant maturity Treasury yield (Federal Reserve Board) for the calendar week preceding the judgment date. Interest is computed daily to payment and compounded annually under 28 U.S.C. § 1961(b).
28 U.S.C. § 1961. Interest shall be allowed on any money judgment in a civil case recovered in a district court. Execution therefor may be levied by the marshal, in any case where, by the law of the State in which such court is held, execution may be levied for interest on judgments recovered in the courts of the State. Such interest shall be calculated from the date of the entry of the judgment, at a rate equal to the weekly average 1-year constant maturity Treasury yield, as published by the Board of Governors of the Federal Reserve System, for the calendar week preceding.
