The formula, as you can see here, is quite easy to understand:

T =72/R, where

T = Time

R = Rate of interest and

72 is a random number that has been chosen for mentally calculating the values easily. Since it is divisible by many numbers, the value of 72 has been fixed as an arithmetical unit for this rule.

For subsequent doubling of investments, this value that we have derived at (7.2 years) needs to be added on to know how exponentially your investments would grow. The following picture will describe this formula in a simple and logical way:
