Methodology

How This Calculator Works

Florida judgment interest accrues daily under §55.03, Florida Statutes. Each quarter, the Chief Financial Officer publishes a new rate based on the Federal Reserve discount rate plus 400 basis points.

This tool applies each quarterly rate only to the exact days within that quarter — giving you a fully itemized, audit-ready calculation that matches how Florida courts determine interest.

Enter your judgment details The judgment date is day one of accrual. The "calculate through" date is the last day you want included.
We apply each quarterly rate The accrual period is split across every rate change. Each segment uses the exact CFO-published daily rate for that quarter.
Review & export The year → quarter → month tree lets you drill into any period. Export to PDF or Excel for demand letters, motions, or negotiations.
Simple Interest Formula (per segment)
Interest = Principal × Daily Rate × Days in Segment
Repeat for each quarterly segment, then sum — matching the methodology used in Florida courts.
