1. What is the APR Credit Card Formula?

The APR (Annual Percentage Rate) formula calculates the effective annual interest rate for credit card transactions or loans, accounting for both interest and fees.

2. How Does the Calculator Work?

The calculator uses the APR formula:

Where:

• \( I \) — Total interest paid (Rs)
• \( F \) — Fees (Rs)
• \( P \) — Principal amount (Rs)
• \( T \) — Loan term (years)

Explanation: The equation combines all costs of borrowing (interest and fees) relative to the principal amount, then annualizes it based on the loan term.

3. Importance of APR Calculation

Details: APR provides a standardized way to compare loan or credit card costs, helping consumers understand the true cost of borrowing.

4. Using the Calculator

Tips: Enter all amounts in Rs (Indian Rupees) and term in years. Ensure principal amount and term are greater than zero.
