How to Use the Rule of 72?
The Rule of 72 shines in its simplicity. Here’s how to use it for your investment planning:
- Identify Your Investment’s Expected Annual Return: This could be an interest rate for a savings account, a dividend yield for a stock, or the projected average annual return for a mutual fund. Look for this information in the investment prospectus or financial statements.
- Divide 72 by Your Annual Return (as a Percentage): Remember, we don’t convert the percentage into a decimal. For example, if you expect a 5% annual return, divide 72 by 5 to get approximately 14.4 years.
- Interpret the Result: This number represents the estimated time it would take for your investment to double in value, assuming a constant annual return rate and reinvestment of all earnings (compound interest).

The power of compound interest is a cornerstone of wealth building. It’s the concept of “earning interest on your interest,” allowing your money to grow exponentially over time. Imagine investing $1,000 at an annual interest rate of 7%. In just 10 years, thanks to compound interest, your investment will balloon to roughly $1,967. The Rule of 72 is a handy shortcut to estimate how long this impressive growth takes. Albert Einstein famously called it the “eighth wonder of the world” due to its remarkable ability to grow your money over time.
