đź’¨ Abstract

The article from U.S. News & World Report explains the "Rule of 72," a straightforward method for estimating how long it takes for an investment to double based on a fixed annual rate of return. The rule involves dividing 72 by the expected annual rate of return to find the number of years until the investment doubles. For instance, if the return is 6%, it will take 12 years to double (72 / 6 = 12).
