The Rule of 72 is a simple yet powerful financial concept that helps individuals estimate how long it will take for an investment to double in value. The rule states that you can divide 72 by the annual rate of return on an investment to determine approximately how many years it will take for the investment to double. For example, if you have an investment with an annual return of 6%, you can divide 72 by 6 to get 12. This means it will take approximately 12 years for your investment to double in value. Similarly, if you have an investment with an annual return of 8%, it will take approximately 9 years for it to double. The Rule of 72 is a handy tool for quickly assessing the impact of different rates of return on investments and making informed decisions about your financial future. By understanding this rule, you can better plan for your investment goals and make more strategic decisions about how to grow your wealth over time.
