The Rule of 72 is an easy way to approximate how long it will take your savings to double. Just divide 72 by the interest rate you earn to determine the number of years it will take your money to double. It shows the way money can grow faster with a higher rate of return.
Keep in mind that this is just a quick estimate. Depending on changes in the rate of return over time, what you’re invested in, how you invest it, how interest is applied, and possible tax implications, the actual amount of time needed to double your money will vary.
