MANAGEMENT

Detailed explanation-1: -The Rule of 72 is a calculation that estimates the number of years it takes to double your money at a specified rate of return. If, for example, your account earns 4 percent, divide 72 by 4 to get the number of years it will take for your money to double.

Detailed explanation-2: -Do you know the Rule of 72? It’s an easy way to calculate just how long it’s going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.

Detailed explanation-3: -The Rule of 72 gives an estimation of the doubling time for an investment. It is a fairly accurate measurement, and more so when using lower interest rates rather than higher ones. It is used for situations involving compound interest. A simple interest rate does not work very well with the Rule of 72.

Detailed explanation-4: -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.

Detailed explanation-5: -The formula to use the Rule of 72 is as follows: The Rule of 72: Number of years to double the investment = 72/ annual rate of interest.
