Post Judgment Interest Calculator
A court judgment does not always mean the payment process is complete. When a judgment remains unpaid, interest may continue to accumulate depending on the applicable laws, court order, and jurisdiction.
The Post Judgment Interest Calculator helps estimate how much interest may have accumulated after a judgment date by considering:
- Original judgment amount
- Annual interest rate
- Number of days since judgment
- Payment credits already made
This calculator provides an estimate of the current balance, including estimated interest.
What Is Post Judgment Interest?
Post judgment interest is interest that may be added to an unpaid court judgment after the judgment has been entered.
It is designed to compensate the judgment creditor for the delay in receiving payment.
For example:
- A court awards a $10,000 judgment.
- The judgment remains unpaid for one year.
- Interest may accumulate based on the applicable rate.
The final amount owed may become higher than the original judgment amount because of accumulated interest.
How Does the Post Judgment Interest Calculator Work?
The calculator estimates interest using three main inputs:
Judgment Amount
This is the original amount awarded by the court.
Example:
Judgment Amount: $10,000
Annual Interest Rate
This is the yearly interest percentage applied to the unpaid judgment.
Example:
Interest Rate: 5% per year
Time Since Judgment
Interest generally depends on how much time has passed since the judgment date.
Example:
365 days = approximately 1 year
Post Judgment Interest Formula
The basic calculation is:
Interest = Judgment Amount × Annual Interest Rate × Time Period
For daily calculations:
Interest = Judgment Amount × Annual Interest Rate × (Number of Days ÷ 365)
Example:
- Judgment amount: $10,000
- Interest rate: 5%
- Time period: 365 days
Calculation:
$10,000 × 0.05 × (365 ÷ 365)
Estimated interest:
$500
Total amount due:
$10,500

Factors That Can Affect Post Judgment Interest
The actual amount owed may vary because of:
Jurisdiction Rules
Interest rates and calculation methods can differ depending on location.
Court Orders
Some judgments may contain specific instructions about interest.
Payment History
Partial payments may reduce the balance on which interest is calculated.
Additional Fees or Costs
Some judgments may include other recoverable costs depending on applicable rules.
Common Mistakes When Calculating Judgment Interest
Using the Wrong Interest Rate
Different courts and jurisdictions may apply different rates.
Forgetting Payment Credits
Payments can reduce the remaining balance and affect future interest calculations.
Calculating From the Wrong Date
Interest may begin from a specific judgment date determined by court rules.
Treating Estimates as Final Amounts
Online calculators provide estimates and may not include every legal requirement.
