§1961 Interest

Summary

Courts must add interest to money judgments won in a U.S. district court. A marshal can collect that interest if the state where the court sits lets marshals collect interest on state judgments. The interest starts on the day the judge enters the judgment. The rate is the weekly average 1‑year Treasury yield published by the Federal Reserve for the calendar week before the judgment. The Director of the Administrative Office of the U.S. Courts must tell all federal judges what the rate is and when it changes. Interest is figured every day until it is paid and is compounded once a year, except as those rules are changed by section 2516(b) of this title or section 1304(b) of title 31. This rule does not apply to internal revenue tax judgments; those use the underpayment or overpayment rates set in section 6621 of the Internal Revenue Code of 1986. Final judgments against the United States in the Federal Circuit use the rate and calculation above, and the Court of Federal Claims follows paragraph (1) here or any other law that applies. The rule does not change interest rules for courts not named here.
