Louisiana Judicial Interest Calculator
Louisiana judgments carry interest at a rate the state sets each year (La. R.S. 13:4202–4203). This free tool estimates that simple interest — before judgment, from the date of demand, and after judgment, until payment. It is for general information; always confirm the current rate and your specific dates with a lawyer.
Choose a mode, enter the amount and dates, and the tool will compute the interest year by year using Louisiana’s published rates.
Enter the principal (the damages or amount owed), not including interest already accrued.
Prejudgment interest generally runs from the date of judicial demand (or loss) through the date of judgment (R.S. 13:4203).
Please read. This calculator is a free educational aid, not legal advice, and using it does not create an attorney-client relationship. It computes simple interest using Louisiana’s published annual judicial-interest rates (La. R.S. 13:4202 for post-judgment; R.S. 13:4203 for prejudgment), counting the period inclusively and applying each calendar year’s rate. The rates change every year and the most recent figures should be confirmed with the Louisiana Office of Financial Institutions before relying on any number. The correct accrual start date, the treatment of partial payments, and other case-specific rules can change the result. Do not rely on this figure for a filing, demand, or settlement without confirming it with a lawyer.
