Formula and Logic
This calculator uses standard legal interest calculation methods accepted in most civil court systems:
Simple Interest
Calculated as: Interest = Principal × (Annual Interest Rate / 100) × (Days Accrued / 365). Simple interest accrues only on the original principal, with no compounding.
Compound Interest
Calculated using the compound interest formula: Total Amount = Principal × (1 + (Annual Rate / Number of Compounding Periods)) ^ (Total Days / Days per Period). Interest is added to the principal at each compounding interval, so subsequent interest accrues on the growing balance.
Pre-set statutory rates are provided for reference only: actual jurisdictional rates may vary by case type, judgment date, and legislative changes. Always verify current rates with the relevant court or legal authority.
Practical Notes
Default judgment interest rules vary significantly by jurisdiction, so keep these legal-specific considerations in mind:
- Statutory interest rates are subject to change: US federal post-judgment rates, for example, are updated quarterly by the Treasury Department.
- Some jurisdictions cap the maximum interest rate that can be applied, or exclude certain types of judgments from interest accrual.
- Compound interest is not permitted in all jurisdictions for default judgments: check local rules before using compound calculations.
- Interest typically begins accruing the day after the judgment is officially entered, not the date of the underlying incident or filing.
- This tool does not account for partial payments, judgment modifications, or post-judgment credits that may reduce interest obligations.

Frequently Asked Questions
Are these interest calculations legally binding?
No. This tool provides estimates for reference only. All default judgment interest obligations must be verified with a qualified attorney and the relevant court. Statutory rates, calculation methods, and eligibility rules vary by jurisdiction and case-specific factors.
What if my jurisdiction is not listed in the dropdown?
Select "Custom Jurisdiction" from the jurisdiction dropdown, then switch the Interest Rate Type to "Custom Rate" to enter the correct annual interest rate for your location. You can find current statutory rates on your local court’s official website or through a legal professional.
Does this tool account for partial payments made on the judgment?
No. This calculator assumes no partial payments, credits, or modifications to the judgment principal during the accrual period. If payments were made, you will need to adjust the principal amount manually for each period, or consult a legal professional for accurate calculations.
Additional Guidance
Always consult a qualified attorney before relying on these estimates for legal proceedings, tax filings, or financial planning. Interest rules may differ for different case types (e.g., consumer debt, commercial disputes, personal injury) even within the same jurisdiction.
Keep records of all judgment documents, including the official entry date and any court orders modifying interest terms. If you are unsure of the correct interest rate or calculation method for your case, contact the clerk of the court that issued the judgment for official guidance.
