Where:

Total Interest = The sum of all interest charges on your credit card statement
Total Amount Spent = The sum of all purchases made with your credit card

Example Calculation

FAQ

What does a high percentage of total interest paid mean?

A high percentage of total interest paid indicates that a significant portion of your credit card spending is going toward interest charges. This typically happens when you carry a balance from month to month, as interest accrues on the outstanding balance. It's generally advisable to pay your credit card balance in full each month to minimize interest charges.

How can I reduce the percentage of total interest paid?

To reduce the percentage of total interest paid, you can:

Pay your credit card balance in full each month
Consider transferring balances to a 0% APR card
Use cash back or rewards cards to earn points
Negotiate with your credit card company for lower interest rates

Is the percentage of total interest paid the same as the APR?

The APR is the interest rate charged on your credit card balance, while the percentage of total interest paid is a calculation based on your actual spending and interest charges. The APR determines how much interest you'll pay each month, while the percentage of total interest paid shows what portion of your spending went to interest.
