1. What is Monthly Credit Card Interest?

Monthly credit card interest is the amount charged by credit card companies on outstanding balances. 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 (Rs)
• \( P \) — Principal balance (Rs)
• \( R \) — Monthly interest rate (APR / 12 / 100)

Explanation: The annual percentage rate (APR) is divided by 12 to get the monthly rate and by 100 to convert from percentage to decimal.

3. Importance of Interest Calculation

Details: Understanding how interest is calculated helps consumers make informed decisions about credit card payments and debt management.

4. Using the Calculator

Tips: Enter your current credit card balance in Rs and the annual percentage rate (APR) as shown on your statement. All values must be valid (balance > 0, APR ≥ 0).
