How much time does it take for your money to double?

You can estimate doubling time using the Rule of 72. Simply divide 72 by your annual rate of return to know approximately how many years it will take for your money to double. This rule works best for lower interest rates; at higher rates, the estimate becomes less precise. The table below shows the difference between Rule of 72 calculations and actual doubling time:

Frequently asked questions

What is the easiest way to double your money?

To calculate this, divide 72 by your investment’s yearly return. For example, at a 6% return, 72 ÷ 6 = 12 years. This gives a simple estimate, especially useful for moderate interest rates.
