1. What is Credit Card Interest?

Credit card interest is the amount you're charged for borrowing money, calculated as a percentage of your outstanding balance. The APR (Annual Percentage Rate) is the yearly interest rate, but interest is typically calculated monthly.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest (currency unit)
• \( P \) — Principal balance (current amount owed)
• \( R \) — Monthly interest rate (APR ÷ 12, as decimal)

Explanation: The formula calculates how much interest you'll pay each month based on your current balance and APR.

3. Importance of Understanding Credit Card Interest

Details: Knowing how interest is calculated helps you make informed decisions about paying down debt and choosing credit cards with favorable terms.

4. Using the Calculator

Tips: Enter your current credit card balance and the card's APR. The calculator will show your estimated monthly interest charge if you don't pay the balance.
