Interest is allowed on most judgments entered in the federal courts from the date of judgment until paid. The types of judgments generally fall under one of three statutes:
28 U.S.C. § 1961, which governs civil and bankruptcy adversary judgment interest;
18 U.S.C. § 3612 (f)(2), which governs criminal judgments or sentences; and
- 40 U.S.C. § 3116, which governs deficiency judgments in condemnation proceedings.
These statutes should be checked for the latest changes. Under each, the rate of interest used to calculate the amount of post-judgment interest is the nominal weekly average one-year constant maturity United States Treasury yield. This data is published by the Federal Reserve System.
The Federal Reserve Board publishes the following interest rates in the H.15 release: federal funds (effective), commercial paper, bank prime loan, discount window primary credit, and United States Treasury securities. Weekly and monthly averages are available through the Board's Data Download Program. The H.15 is published at 4:15 p.m. every business day (excluding holidays).
