The Rule of 72 formula

The Rule of 72 is an easy way that you can estimate the number of years it will take for an investment to double by

dividing 72 by the annual rate of return.

For Example

If the annual rate of return is 6%, it would take approximately 12 years for the investment to double (72 ÷ 6 = 12).

If the annual rate of return is 9%, it would take approximately 8 years for the investment to double (72 ÷ 9 = 8).

If the annual rate of return is 12%, it would take approximately 6 years for the investment to double  (72 ÷ 12 = 6).
