It makes sense. The card with the highest interest rate is usually the one that will cause you the most financial pain. The national average interest rate on a credit card is 15.2 percent, so if you bought a $1,000 refrigerator with a credit card, you'd pay a lot in interest if you took your time paying it off.

The interest charge is broken down by transaction type: purchases, cash advances and balance transfers. If you pay less than the full balance, pay after the payment due date (or if your credit card does not have a interest free period) then you will pay interest on those purchases.
