Post Judgment Interest Calculator

To calculate the Accumulated Interest Amount (a.k.a. Post Judgment Interest Rate), follow the below instructions.

  1. Determine the interest rate from the Federal Reserves Interest Rate Tables.
         For the appropriate week ending, look under:
              U.S. government securities - Treasury constant maturities - 1-year
  2. Multiply the Judgment amount times the Interest Rate Percentage. This equals the Annual Interest Amount.
  3. Determine the number of days from the Entered Date of Judgment to the date that the Writ was prepared. This equals the Accumulated Days.
  4. Multiply the Daily Interest Amount by the total days. This equals the Accumulated Interest Amount, which should match the amount on the Writ of Execution/Attachment.
