1. What is Credit Card Interest Rate?

The credit card interest rate is the percentage of the principal balance that the credit card company charges for borrowing money. It's typically expressed as an annual percentage rate (APR) and can significantly impact your total repayment amount.

The calculator uses the simple interest rate formula:

Where:

• Total Interest Paid — The total amount of interest you've paid

• Time — The duration of the loan in years

Explanation: This calculation gives you the average annual interest rate you're paying on your credit card balance.

4. Using the Calculator

Tips: Enter the total interest you've paid, the original principal amount, and the time period in years. All values must be positive numbers.
