1. What is Credit Card Interest?

Credit card interest is the amount charged by credit card companies for carrying a balance. It's calculated based on your principal balance and the annual percentage rate (APR) converted to a monthly rate.

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 ÷ 100)

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

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps in budgeting, debt repayment planning, and evaluating the true cost of carrying credit card balances.

4. Using the Calculator

Tips: Enter your current credit card balance and the APR (found on your statement). The calculator will show your estimated monthly interest charge.

Q3: What's a typical credit card APR?
A: APRs typically range from 12% to 25% or higher, depending on creditworthiness and card type.

Q4: Does this include fees?
