The rule 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 eight percent interest, divide 8 into 72 and get 9 years.

Also, how long does it **take** to double your money at 11%?

Also the question is, how long will it **take** for money to **double** itself at 10% **compounded** monthly? To use the Rule of 72 to figure out when your money will double itself, all you need to know is the annual rate of expected return. If this is 10%, then you’ll divide 72 by 10 (the expected rate of return) to get 7.2 years.

Best answer for this question, how **long** will it take money to double if it is invested at 9% compounded monthly? Also, since the interest rate is 9% but compounded **monthly**, we will divide it by 12, but keep in mind now the answer will be in MONTHS. So, about 92.77 months for the amount to **double**.

Frequent question, how long does it take an **investment** to double compounded quarterly? If the interest per quarter is 4% (but interest is only **compounded** annually), then it will take (72 / 4) = 18 quarters or 4.5 years to double the principal. If the population of a nation increases at the rate of 1% per month, it will **double** in 72 months, or six years.
