1. What is the Credit Card Interest Calculation?

The credit card interest calculation determines how much interest you'll pay each month based on your principal balance and the lowest available interest rate. Understanding this helps in financial planning and debt management.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( P \) — Principal balance (current amount owed)
• \( R_{min} \) — Monthly interest rate (annual rate ÷ 12)
• \( I \) — Monthly interest amount

Explanation: The calculation converts the annual percentage rate (APR) to a monthly rate by dividing by 12, then multiplies by the principal balance to find the interest for one month.

3. Importance of Interest Calculation

Details: Knowing your potential interest payments helps in budgeting, comparing credit card offers, and understanding the true cost of carrying a balance.

4. Using the Calculator

Tips: Enter your current credit card balance and the lowest annual interest rate available. The calculator will show your estimated monthly interest payment at that rate.
