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.
By Steve Bucci â¢ Bankrate.com. Dear Debt Adviser, I have a credit card with a very high interest rate -- 29.9 percent. I've recently asked the bank that issued the card to lower my interest rate because I'm struggling to make the payments every month. The bank said there was nothing it could do and that I have the lowest interest rate available.
