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.
Interest rates vary widely. Some credit card loans are secured by real estate, and can be as low as 6 to 12% in the U.S. (2005). Typical credit cards have interest rates between 7 and 36% in the U.S., depending largely upon the bank's risk evaluation methods and the borrower's credit history.
