Judgment Interest: Calculator

Calculate pre- and post-judgment interest the way courts actually compute it — by statute, day by day, with the rate changes built in. Judgment Interest Calculator is built for attorneys, paralegals, and collections professionals who need a reliable interest number for a demand letter, a motion, a payoff quote, or a judgment. FREE IN EVERY JURISDICTION General mode works anywhere. Enter the rate that applies, set your dates, and get interest, per-diem, and total due. No account, no sign-up, nothing to unlock. PRE-JUDGMENT • Interest by date range or by number of days • 365- or 360-day count basis • Per-diem figure for accrual through a future date • Duration shown in days and in years, months, and days • Option to include or exclude the end date POST-JUDGMENT • Payments applied in the order you choose — principal first or interest first • Unlimited payments, each with its own date and amount • Period-by-period schedule showing days, rate, interest, payments, and running balance • Balance broken into principal remaining and interest still owed DATES • Add or subtract days, weeks, months, or years from any date • Calendar days and court days between two dates • Court-day mode counts only days the courts are open, skipping weekends and federal holidays • Results show the weekday, and say so when a date moves off a weekend or holiday Free — no pack required. STATE PACKS — $0.99 EACH Unlock any state and the statutory rate fills in automatically, with the governing citation and the caveats worth checking. All 50 states plus the District of Columbia are available. Fixed-rate states pre-fill their statutory rate. Split, variable, and discretionary states pre-fill the most common or current rate and flag the claim-type, floating, and compounding issues to verify. Where a post-judgment rate floats or is left to the court's discretion, the field starts blank so you enter the current figure. NEVADA The Nevada pack goes further. Choose the governing statute — NRS 17.130, 99.040, or 108.237 — and the app applies prime plus the statutory margin, re-rated automatically every January 1 and July 1 using built-in rate history from 2010 forward. The schedule shows exactly where each rate change lands.
