Calculating Post Judgment Interest Rate


Local Rule #

Federal Rule #




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.

  2. Multiply the Judgment amount times the Interest Rate Percentage. This equals the Annual Interest Amount.

  3. Divide the Annual Interest Amount by 365 days. This equals the Daily Interest Amount.

  4. Determine the number of days from the Entered Date of Judgment to the date that the Writ was prepared. This equals the Accumulated Days.

  5. 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.

Examples of Calculations:

  1. $150,000 (Judgment) x 2.24% (Interest Rate) = $3360 (Annual Interest Amount)

  2. $3360 (Annual Interest Amount) / 365 (Days in the Year) = $9.20 (Daily Interest Amount)

  3. February 1, 2004 (Entered Date of Judgment) to February 18, 2005 (Date Writ prepared) = 382 days (Accumulate Days)

  4. $9.20 (Daily Interest Rate) x 382 (Accumulated Days) = $3514.44 (Accumulated Interest Amount)
