1. What is Credit Card Interest?

Credit card interest is the cost of borrowing money on your credit card. It's calculated based on your average daily balance, annual percentage rate (APR), and the number of days in your billing cycle.

2. How Does the Calculator Work?

The calculator uses the credit card interest formula:

Where:

• \( Average\_daily\_balance \) — Your average balance during the billing cycle
• \( APR \) — Annual Percentage Rate (your interest rate)
• \( Days\_in\_billing\_cycle \) — Typically 28-31 days

Explanation: The formula calculates daily interest by dividing APR by 365, then multiplies by your balance and number of days in the billing cycle.

3. Importance of Understanding Credit Card Interest

Details: Knowing how interest is calculated helps you make informed decisions about credit card use, payments, and debt management.

4. Using the Calculator

Tips: Enter your average daily balance in dollars, APR as a percentage, and number of days in billing cycle (typically 30). All values must be positive numbers.
