What is the Federal Post-Judgment Interest Rate Calculator?
The federal post-judgment interest rate calculator is a specialized financial tool designed to help individuals, legal professionals, and businesses determine the amount of interest that accrues on a judgment awarded in a U.S. federal court. Post-judgment interest is a statutorily mandated interest that begins to accrue on the amount of a money judgment from the date it is entered by the court until it is satisfied.
Who Should Use It?
- Litigants: Plaintiffs seeking to understand the full amount owed to them, including accrued interest.
- Defendants: Individuals or entities responsible for paying a judgment, needing to calculate the total debt.
- Attorneys: Legal professionals representing either party, needing precise calculations for settlements, appeals, or enforcement actions.
- Financial Analysts: Those tracking legal settlements or potential financial liabilities.
Common Misunderstandings:
- Rate Fluctuation: A common misconception is that the federal post-judgment interest rate is fixed. In reality, it is adjusted quarterly and is tied to the auction rate of U.S. Treasury bills. This means the rate can change throughout the life of a judgment.
- Calculation Basis: Some may assume interest is only calculated on the principal judgment amount. However, the interest itself can potentially accrue interest, though simple interest is most commonly applied to the principal amount of the judgment. This calculator assumes simple interest on the principal judgment amount.
- Jurisdiction Specificity: While this calculator focuses on federal post-judgment interest, state courts have their own distinct post-judgment interest rules and rates that can differ significantly.
Federal Post-Judgment Interest Rate Formula and Explanation
The calculation of federal post-judgment interest is governed by 28 U.S. Code § 1961. The standard formula used to calculate the accrued interest is a simple interest calculation:
Accrued Interest = Principal Judgment Amount × (Annual Interest Rate / 365) × Number of Days
Let's break down the variables:
| Variable | Meaning | Unit | Typical Range / Notes |
|---|---|---|---|
| Principal Judgment Amount | The original monetary award granted by the court. | USD ($) | Any positive value. |
| Annual Interest Rate | The federal post-judgment interest rate, expressed as a percentage. This rate is variable. | Percentage (%) | Varies quarterly. Consult official U.S. Courts or Treasury sources for current rates. Example: 1.00% (0.01 in decimal form). |
| Number of Days | The total number of days between the judgment date and the calculation date (or date of payment). | Days | A positive integer. |
| Accrued Interest | The total amount of interest calculated to be due. | USD ($) | Calculated value. |
| Total Judgment Amount | The sum of the principal judgment amount and the accrued interest. | USD ($) | Principal + Accrued Interest. |
The interest rate is determined by averaging the discount rates of U.S. Treasury bills (T-bills) for the 52-week period ending on the Thursday of the preceding week. This average rate is then used for the subsequent quarter.
Practical Examples of Federal Post-Judgment Interest
Here are a couple of scenarios to illustrate how the federal post-judgment interest calculator works:
Example 1: Standard Judgment
Scenario: A contract dispute results in a $50,000 judgment entered on March 15, 2023. You want to calculate the total amount owed on July 15, 2024. The relevant federal post-judgment interest rate for the period was an average of 2.50% annually.
- Judgment Amount: $50,000.00
- Judgment Date: March 15, 2023
- Calculation Date: July 15, 2024
- Annual Interest Rate: 2.50%
Using the calculator:
- Number of Days: 487 days
- Accrued Interest: $50,000.00 × (2.50% / 365) × 487 ≈ $1,667.53
- Total Judgment Amount: $50,000.00 + $1,667.53 = $51,667.53
Example 2: Smaller Judgment with Later Calculation
Scenario: A small claims case in federal court results in a $5,000 judgment on September 1, 2022. The debtor pays the full amount on September 1, 2024. The federal post-judgment interest rate averaged 1.75% annually over this period.
- Judgment Amount: $5,000.00
- Judgment Date: September 1, 2022
- Calculation Date: September 1, 2024
- Annual Interest Rate: 1.75%
Using the calculator:
- Number of Days: 730 days (2 full years)
- Accrued Interest: $5,000.00 × (1.75% / 365) × 730 ≈ $175.00
- Total Judgment Amount: $5,000.00 + $175.00 = $5,175.00
This highlights how even small interest rates can add up over time, making it crucial to accurately calculate accrued interest on judgments.
How to Use This Federal Post-Judgment Interest Rate Calculator
Using our federal post-judgment interest rate calculator is straightforward. Follow these simple steps:
- Enter Judgment Amount: Input the exact dollar amount of the original court judgment.
- Input Judgment Date: Select the official date the judgment was entered by the federal court. This is critical for determining the start of the interest accrual period.
- Specify Calculation Date: Choose the date up to which you want to calculate the accrued interest. This might be the current date, a proposed settlement date, or the date of payment.
- Provide Annual Interest Rate: Enter the applicable federal post-judgment interest rate for the period. Remember, this rate is set quarterly and can change. For the most accurate, up-to-date rate, consult official sources from the U.S. Courts or U.S. Department of the Treasury. The calculator uses the rate you provide as a static annual rate for the entire duration.

- Copy Results: Use the 'Copy Results' button to easily transfer the calculated figures to another document or application.
- Reset: If you need to start over or input new figures, click the 'Reset' button to return the calculator to its default values.
Selecting Correct Units: All monetary values should be entered in USD ($). Dates should be in a standard calendar format. The interest rate must be entered as a percentage (e.g., 2.5 for 2.5%).
Interpreting Results: The 'Accrued Interest' is the total interest earned from the judgment date to the calculation date. The 'Total Judgment Amount' is the principal judgment plus this accrued interest, representing the full amount potentially owed.
Key Factors That Affect Federal Post-Judgment Interest
Several elements influence the final amount of interest accrued on a federal judgment:
- Principal Judgment Amount: This is the most direct factor. A larger judgment amount will result in a higher accrued interest, assuming all other variables remain constant.
- Duration of the Judgment: The longer the time between the judgment date and the satisfaction date, the more interest will accrue. Even a low daily rate accumulates significantly over years.
- Federal Interest Rate: This is a critical variable. Changes in the T-bill auction rates directly impact the post-judgment rate. Higher rates lead to faster interest accumulation, while lower rates slow it down. The rate is set quarterly, so understanding the specific rate applicable during different periods of the judgment's life is important for precision.
- Number of Days Calculation: Accurately calculating the exact number of days between the judgment date and the payment date is crucial. This includes accounting for weekends and holidays implicitly, as the rate is applied daily.
- Payment Timing: If a judgment is paid in installments, the calculation of interest might become more complex, potentially requiring calculations for each period. This calculator assumes a single payment event.
- Statutory Limits or Agreements: While 28 U.S. Code § 1961 is the general rule, specific circumstances or pre-existing agreements could potentially alter interest accrual, though this is rare in standard federal judgments.
Frequently Asked Questions (FAQ) about Federal Post-Judgment Interest
- Q1: What is the current federal post-judgment interest rate?
- A1: The federal post-judgment interest rate is reset quarterly and is based on the 52-week U.S. Treasury bill auction rate. To find the most current rate, you should consult official sources like the U.S. Courts website or the U.S. Department of the Treasury. This calculator uses the rate you input.
- Q2: How is the number of days calculated?

- Q3: Does the interest rate change during the life of the judgment?
- A3: Yes, the federal post-judgment interest rate is adjusted quarterly. This calculator uses a single, static annual rate that you provide. For a highly precise calculation spanning multiple quarters with changing rates, you would need to perform calculations for each quarter separately using the applicable rate.
- Q4: Can interest accrue on the accrued interest?
- A4: Generally, federal post-judgment interest accrues on the principal amount of the judgment. While some legal contexts might involve compounding, 28 U.S. Code § 1961 typically implies simple interest on the judgment award. This calculator applies simple interest.
- Q5: What if the judgment is for something other than money?
- A5: Post-judgment interest under 28 U.S.C. § 1961 typically applies only to monetary judgments. Non-monetary judgments are treated differently.
- Q6: How accurate is this calculator?
- A6: The calculator is accurate based on the inputs provided and the simple interest formula. However, it relies on the user inputting the correct, current federal interest rate. For critical legal or financial decisions, always cross-reference with official data and consult legal counsel.
- Q7: Can I calculate interest for state court judgments with this tool?
- A7: No, this calculator is specifically for U.S. federal court judgments. State courts have their own statutes governing post-judgment interest rates and calculation methods, which can differ significantly.
- Q8: What happens if I enter a judgment date after the calculation date?
- A8: The calculator will show 0 days and 0 accrued interest, as the period would be negative. It's designed to calculate interest for periods where the calculation date is on or after the judgment date.
