The best definition for 72 is the number before 73 and after 71.
Rule of seventy two is used to ascertain the period by which an investment would grow by 100%. 72 divided by rate of interest would provide the approximate period by which the investment would become double. As an example, if the rate of interest is 6% per month, the investment would be doubled in ( 72/6) 12 months. Rule of 72 thus is an important tool to know the investment horizon.
