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


How to Use the Post Judgment Interest Calculator

Follow these steps:

Step 1: Enter Judgment Amount

Enter the original court-awarded amount.

Example:

$10,000


Step 2: Add Annual Interest Rate

Enter the applicable yearly interest rate.

Step 3: Enter Days Since Judgment

Enter the number of days that have passed since the judgment was entered.

Step 4: Add Payment Credits

If payments have already been made, enter the amount paid.

Example:

Payment credits:

$2,000

The calculator adjusts the remaining principal balance.


Step 5: Review Results

The calculator estimates:

  • Accumulated interest
  • Remaining principal after payments
  • Total amount due
  • Calculation period

Example Post Judgment Interest Calculation

Suppose:

Item Amount
Judgment amount $10,000
Annual interest rate 5%
Time passed 365 days
Payment credits $0

Estimated calculation:

Interest:

$500

Principal:

$10,000

Estimated total amount due:

$10,500

This example assumes simple interest and does not include additional court-specific adjustments.


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.
