Abracadabra!It's not a magic trick–it's the mental math shortcut everyone on Earth should know.
The Rule of 72 is a simple formula that can be used to approximate the number of years it will take for your money to double.
You simply divide 72 by your interest rate.
Like magic, the result is the number of years it will take your money to double.
72 ÷ interest rate = years to double
Estimating doubles can help simplify money decisions. This is a practical formula.
The higher your interest rate, the fewer years it takes your money to double.
Select an interest rate:
1^{%}
3^{%}
6^{%}
9^{%}
12^{%}
72 ÷1^{%} =72 years to double
