The Rule of 72 is a quick and easy way to estimate how long it will take for an investment to double in value based on a given interest rate. To use this rule, you simply divide 72 by the interest rate. For example, if you have an investment with an interest rate of 6%, it will take approximately 12 years (72 divided by 6) for it to double in value. This rule is a helpful approximation and can be used to make quick investment decisions.
