Personal Finance Tip: A New Look at The Rule of 72!

Most investors have heard or read of the rule of 72 and how this exemplifies the magic of compounding interest. I was thinking of The rule of 72 the other day as it applies to credit card balances and making minimum payments! As a short refresher, the rule of 72 simply says that if you are making 10% on your money in a tax deferred account, your money will double in 7.2 years. 72 divided by 10.

Imagine now that if you have a credit card balance that you are paying 16% interest on. If you miss payments or have late fees added on those will be magically compounding in a very negative way. Imagine this: 72 divided by 16% = 4.5 Years!!
It doesn’t quite happen that way but clearly you can see if you just make minimum payments your balance doesn’t really go away any time soon.
