Explanation: 

Detailed explanation-1: -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-2: -For example, with a 9% rate of return, the simple calculation returns a time to double of eight years.

Detailed explanation-3: -The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at eight percent interest, divide 8 into 72 and get 9 years.

Detailed explanation-4: -It’s called the Rule of 72. The principle is simple. Divide 72 by the annual rate of return to figure how long it will take to double your money. For example, if you earn an 8 percent annual return, it will take about 9 years to double.
