1. What is Daily Interest Calculation?

Daily interest calculation determines the amount of interest that accrues each day on an auto loan. This helps borrowers understand how much interest they're paying daily and can inform decisions about early payments.

2. How Does the Calculator Work?

The calculator uses the daily interest formula:

Where:

• \( I_{daily} \) — Daily interest (currency)
• \( P \) — Principal amount (currency)
• \( r \) — Annual interest rate (decimal)

Explanation: The formula calculates the daily interest by dividing the annual rate by 365 days and multiplying by the principal amount.

3. Importance of Daily Interest Calculation

Details: Understanding daily interest helps borrowers make informed decisions about loan payments, especially when considering early payments or evaluating different loan options.

4. Using the Calculator

Tips: Enter the principal amount in currency and annual interest rate as a decimal (e.g., 0.05 for 5%). Both values must be valid (principal > 0, rate ≥ 0).
