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.
The rate of interest is 2% per month. For 12 months the equivalent rate of interest is (1+.02) ^12 -1. This is approximately 26.82 %. The equivalent annual interest rate for the credit card is 26.82%. So for an amount of $1000, the interest to be paid is $268.2.
