Which of the following accounting rules can roughly estimate how many years a given sum of money must earn at a given compound annual interest rate in order to double that initial amount.
The Rule of 72 is a simple way to determine how long an investment will take to double given a fixed annual rate of interest. By dividing 72 by the annual rate of return, investors obtain a rough estimate of how many years it will take for the initial investment to duplicate itself. However the Rule of 72 is reasonably accurate for low rates of return.
