Understanding the Rule of 72

The Rule of 72 is a simple, mental math shortcut to estimate the number of years required to double your investment at a given annual fixed interest rate.

Years to Double ≈ 72 ÷ Interest Rate

For example, with an annual return of 10%:

  • The calculation is 72 ÷ 10.
  • This gives approximately 7.2 years to double your money.
  • While the Rule of 72 is an approximation, the actual time (calculated using precise logarithmic formulas) is very close to this estimate for typical interest rates (between 6% and 10%).

This rule applies to any investment with compound interest, helping investors quickly gauge the potential growth of their portfolio without complex calculations.
