Show the math
Costs are the sum of fees plus simple interest on any judgment:
interest = principal × rate × days ÷ 365
total = fees + interest
Court fees are set by each court's schedule and fee waivers may apply. Post-judgment interest rates are set by statute and may compound differently. Confirm exact amounts with the court clerk. All math runs locally in your browser.
What this does
A court filing fee calculator adds up court costs (filing, service, and motion fees) plus simple post-judgment interest on an award to estimate your total.
How it works
Court costs are summed directly. Post-judgment interest uses simple interest: the principal times the annual statutory rate times days, divided by 365.
Interest = principal × rate × days ÷ 365
How to use it
- Enter the filing, service, and motion fees.
- Enter any judgment amount and statutory rate.
- Enter the days since judgment.
- Read the total court costs and interest.
Understanding your result
Fee schedules vary by court, and some jurisdictions compound interest differently. Courts may waive fees for those who qualify financially (in forma pauperis), ask the clerk.
Example
A $405 federal district court filing fee plus $75 for service is $480 in fees; one year of 5% interest on a $10,000 judgment adds $500, for $980 in total.
