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. It accrues daily but is typically charged monthly.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest amount ($)
• \( P \) — Principal balance ($)
• \( R \) — 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 annual interest rate.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting, debt repayment planning, and evaluating the true cost of carrying a balance.

4. Using the Calculator

Tips: Enter your current credit card balance and annual percentage rate (APR). Both values must be positive numbers.
