related. The rule of 72 is the length of time it takes a lump sum of money to double at a given interest rate. Example if you get a 10% return on your money divide 72/10= 7.2. It takes 7.2 years for a lump sum if money to double. If I consistently get a 10% return \$1000 today will be worth \$2000 in 2019.
I think it's criminal not to teach this in schools!!!!

so from the banks point if view..... The average credit card balance is \$5800 @ 24% interest. Sooo 72/24= 3yrs. Which means if you aren't paying off your credit card the bank loves you!!!! Your unpaid balance of \$5800 turns into them having \$11,600 in just 3 years!!! Thank you public school system for keeping the US broke!!!!

The banks use it to assess compound interest.
