The Rule of 72 is a simple yet powerful tool for estimating how long it takes for your investments to double. By dividing 72 by the interest rate, you get an approximate number of years.

For example:

  • At a 6% interest rate, your investment doubles in approximately 72 / 6 = 12 years.
  • At a 9% interest rate, it doubles in approximately 72 / 9 = 8 years.

  • Quick and Easy: It provides a rough estimate without complex calculations.
  • Understanding Compounding: It demonstrates the power of compound interest.
  • Investment Planning: Helps you set realistic financial goals.
