1. What is the HDFC Credit Card Interest Calculation?

The HDFC credit card interest calculation determines the monthly interest charged on outstanding balances. It uses the simple interest formula based on the principal balance and the monthly interest rate (APR divided by 12).

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

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

Explanation: The equation calculates the interest charged for one month on the outstanding credit card balance.

3. Importance of Interest Calculation

Details: Understanding monthly interest helps cardholders estimate repayment costs, plan payments, and avoid accumulating excessive debt.
