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:

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

Explanation: The APR is divided by 12 to get the monthly rate, then multiplied by the principal balance to determine the monthly interest charge.

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 card offers.

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.

Q2: How can I reduce my credit card interest?

Q3: What's a good APR for a credit card?
A: As of 2023, average APRs range from 15-25%. Rates below 15% are considered good, while rates above 25% are high.

Q4: Does this calculator account for compound interest?

Q5: How is APR different from interest rate?
