Method & sources

The scheduled rate comes from the preceding calendar week’s H.15 one-year Treasury average. Apply the annual rate at each complete judgment anniversary, then accrue the remaining days at one three-hundred-sixty-fifth of the annual rate per day. Round the estimate to cents at the end.

What if the judgment was entered on the rate release date?

Court guidance can call for the prior release. Check your court’s instructions and enter the verified rate. The calculator asks for confirmation on Mondays and on Tuesdays after a standard Monday federal holiday.
