1. What is the Monthly Credit Card Interest Calculation?

The monthly credit card interest payment is calculated using the principal balance and the monthly interest rate (APR divided by 12). This shows how much interest accrues each month on your outstanding balance.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest payment ($)
• \( P \) — Principal balance ($)
• \( R \) — Monthly interest rate (APR / 12 as decimal)

Explanation: The formula multiplies your current balance by the monthly interest rate (annual rate divided by 12 months) to determine your monthly interest charge.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with debt repayment planning and shows the true cost of carrying a credit card balance.

4. Using the Calculator

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