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.
In our survey of credit cards the penalty APR is generally dependent upon the card issuer. The maximum allowable interest rate on any credit card is 29.99%. As you can see from this data, the penalty / default rates are at the minimum 7-8% higher than the worst rates you would normally see on your credit cards.
