Rule of 72 - the doubling of moneyThe Rule of 72 says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at a 9 percent interest, divide 72 by 9 and get 8 years.

Thanks for posting this. Now I know how to calculate doubling my money.

But, what if I want to figure out in my head the calculation for tripling or quadrupling my investments?

Anyone know?
