1. What is California Post-Judgment Interest?

California law mandates a 10% annual simple interest rate on most money judgments. This interest accrues from the date of judgment entry until the judgment is paid in full.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Principal \) — Original judgment amount (USD)
• \( 0.10 \) — California's 10% annual interest rate
• \( Days \) — Number of days since judgment

Explanation: The calculation uses simple interest (not compounded) based on the exact number of days the judgment remains unpaid.

3. Importance of Interest Calculation

Details: Accurate interest calculation ensures creditors receive full compensation owed under California law and helps debtors understand their total obligation.

4. Using the Calculator

Tips: Enter the original judgment amount in USD and the number of days since judgment was entered. Both values must be positive numbers.
