1. What is Credit Card Interest Calculation?

Credit card interest calculation determines how much interest you'll pay on your outstanding balance. It's based on your average daily balance, annual interest rate, and the number of days in your billing cycle.

2. How Does the Calculator Work?

The calculator uses the credit card interest formula:

Where:

• \( ADB \) — Average Daily Balance (currency units)
• \( R \) — Annual Interest Rate (%)
• \( D \) — Days in Billing Cycle (days)

Explanation: The formula calculates daily interest by converting the annual rate to a daily rate, then multiplies by the average balance and number of days in the cycle.

3. Importance of Interest Calculation

Details: Understanding how credit card interest is calculated helps consumers make informed financial decisions, manage debt effectively, and avoid unnecessary interest charges.

4. Using the Calculator

Tips: Enter your average daily balance in currency units, annual interest rate as a percentage, and number of days in your billing cycle. All values must be positive numbers.
