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.
Average credit card interest rates rise to 15.07 percent. Average rates on new card offers jumped this week to the highest point in nearly three years, according to the CreditCards.com Weekly Credit Card Rate Report. The national average annual percentage rate (APR) rose to 15.07 percent Wednesday after falling to 15.05 percent the previous week. The last time the average rate was this high was in January 2012, when the national average hit 15.14 percent. This week's rate increase was spurred by a change to a regional issuer's card offerings.
