Federal post-judgment interest calculator

Interest on a money judgment in a civil case in a district court runs from the date of entry at a rate equal to the weekly average 1-year constant maturity Treasury yield, as published by the Federal Reserve, for the calendar week preceding the judgment. It is computed daily to the date of payment and compounded annually (1961(b)).

The latest week in the table ended on 30 October 2026 at 4.44%, which sets the rate for judgments entered from 2 to 8 November 2026. The rate is fixed on entry; later weeks do not change it.

A $250,000 judgment entered on 4 November 2026 takes 4.44% and earns $30.41 a day. Paid on 4 November 2027, exactly a year later, the interest is $11,100.00. If it is paid on 3 May 2028 instead, the second stretch runs on $261,100: another 181 days at 4.44% adds $5,748.78, so the interest is $16,848.78.

The same weekly rate is used for criminal judgments under 18 U.S.C. 3612(f)(2) and condemnation deficiency judgments under 40 U.S.C. 3116, though each statute applies it in its own way. There is no federal statute for prejudgment interest in most cases; courts award it at their discretion, often at the 1961 rate or the state rate. Read the statute that governs your judgment, and compare state rates in the judgment interest calculator for every state.
