1. What is Credit Card Interest Calculation?

Credit card interest calculation determines the amount of interest charged on outstanding credit card balances during a billing period. It helps cardholders understand the cost of carrying a balance and make informed financial decisions.

2. How Does the Calculator Work?

The calculator uses the interest calculation formula:

Where:

• \( ADB \) — Average Daily Balance (currency units)
• \( R \) — Annual Interest Rate (%)
• \( D \) — Number of 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 billing cycle.

3. Importance of Interest Calculation

Details: Understanding credit card interest helps consumers manage debt, avoid excessive charges, and make timely payments to minimize interest expenses.

4. Using the Calculator

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