The rule of 114 is a fast mental shortcut for estimating how long it takes an investment to triple in value: divide 114 by the annual return percentage and you get the approximate number of years. It is the tripling cousin of the better known rule of 72 for doubling, and it comes from the natural logarithm of three. This calculator does the division for you and also works in reverse, telling you the annual return you would need to triple your money within a target number of years. Enter a rate to see the years to triple, or enter a time frame to see the required rate. It is a handy sanity check for growth expectations without pulling out compound interest formulas. The approximation is close for typical single digit and low double digit returns. All math runs in your browser.
It estimates how long money takes to triple by dividing 114 by the annual return percent. At 10 percent, tripling takes about 11 years.
The rule of 72 estimates doubling time, while 114 estimates tripling, both using the same divide by the rate shortcut.
Yes. Enter a target number of years and the tool divides 114 by it to estimate the required annual return.
