Frequently asked questions
- What is pre-judgment interest?
- Pre-judgment interest compensates the winning party for the time value of money between when the debt arose and when judgment is entered. Courts apply either the statutory rate or the contract rate.
- Is interest compounded in small claims?
- Most jurisdictions apply simple interest (not compound) for pre-judgment purposes. Post-judgment interest rules differ and may compound.
- What rate should I use?
- Use the rate specified in your contract, or look up your state's statutory post-judgment or pre-judgment interest rate. Common US rates range from 5% to 12% per year.
