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 charge

Explanation: The calculator converts your APR to a monthly rate by dividing by 12, then multiplies this rate by your current balance to estimate your monthly interest charge.

3. Importance of Interest Calculation

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

4. Using the Calculator

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

Q3: What if my APR changes?
