The federal post-judgment interest rate is the interest that accrues on money judgments entered in U.S. federal courts. By statute (28 U.S.C. §1961) it equals the weekly-average 1-year Treasury constant maturity yield for the calendar week preceding the judgment — a value the U.S. Courts publish only as a formula, not a number, and that changes every week. This page computes it from the official Federal Reserve H.15 series and records each value under the following judgment-applicability week.

How this value is derived. Applies to supported judgments in the calendar week beginning 2026-10-05; derived from the FRED DGS1 weekly average for the preceding source week beginning 2026-09-28 and independently cross-checked against published WGS1YR. Under 28 U.S.C. §1961, the post-judgment rate uses the weekly-average 1-year Treasury constant-maturity yield for the calendar week preceding the judgment date. The current formula applies only to judgments entered on or after 2000-12-21. Confirm the applicable week against the court table. Reference, not legal advice.
