1. What is Credit Card Interest Calculation?

Credit card interest calculation determines how much interest you'll pay on your outstanding balance. For Chase and most credit cards, interest is calculated using the average daily balance method with daily compounding.

2. How Does the Calculator Work?

The calculator uses the interest 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 how credit card interest is calculated helps consumers make informed decisions about payments, balance management, and overall credit card usage to minimize 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.
