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 outstanding balance and the annual percentage rate (APR) set by your credit card issuer.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest amount
• \( P \) — Principal balance (current amount owed)
• \( R \) — Monthly interest rate (APR ÷ 12)

Explanation: The APR is converted to a monthly rate by dividing by 12, then multiplied by the principal balance to determine the interest for that month.

3. Importance of Interest Calculation

Details: Understanding how interest is calculated helps you make informed decisions about paying down credit card debt and comparing different credit offers.

4. Using the Calculator

Tips: Enter your current credit card balance and the APR (found on your statement). The calculator will show how much interest you'll pay for one month if you don't make any payments.
