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.
Federally chartered credit unions have an interest rate cap of 18 percent on all loans, not just credit cards, according to the Credit Union National Association. If your 27.99 percent annual percentage rate, or APR, is the result of a rate increase, you should know your rights under the new law. The CARD Act requires issuers to review rate increases that occurred after Jan. 1, 2009, every six months and reduce the person's interest rate if appropriate.
