What this page sets up
The calculator opens for a court judgment: 25,000 at 10% a year, counted between two dates on a 365-day year, with simple interest in the large figure because most judgment statutes don’t compound. Pick the court under Where the judgment was entered to fill in its rate, or type the rate from the judgment itself, which is what counts. Set From to the date the judgment was entered and To to the day you want the balance for. Simple interest per day under the result is the daily figure courts and collection letters use.
Reading the result
The large figure is the judgment plus the interest that has run on it: simple interest, or interest compounded once a year after you pick a jurisdiction whose statute compounds, as the line under the picker says. The two cards show both ways side by side. The year-by-year schedule shows how much has accrued by each anniversary of the judgment.
Before you rely on the figure
- Contract rates come first in many states. A judgment on a note or a loan agreement often carries the rate the contract set, not the statutory rate.
- Variable rates are fixed at different times. Some states fix the rate on the judgment date, others reset it every year for old judgments too. The table says which.
- Payments and costs. Subtract payments as they happen and work out each period separately; court costs and fees may or may not earn interest.
- This is arithmetic, not legal advice. Statutes change and courts can order a different rate, so check the judgment and the current statute, or ask the court clerk or a lawyer.
To count interest on an ordinary late payment or loan between two dates, the daily interest calculator does the same day count without the court rates.
Post-judgment interest rates by jurisdiction (September 27, 2026)
The statutory rate on a civil money judgment entered on September 27, 2026. Each rule was read that day on the jurisdiction's official statute, court or agency page; where the official site refused our connection, from a Wayback Machine copy of that page, and for Georgia and Arkansas from the act that set the rule, as noted under each source. Where the rate follows a market index on the day of judgment, the rule is given without a number: look up the index for your date. Interest per day is on a $10,000 judgment.
