On this page is a quadrupling time calculator. Enter a rate of return in percentage form, and the tool will tell you how many periods at that rate of return it'll take something to quadruple, or 4x.

quadrupling\ time=\frac{\ln(4)}{\ln(1+rate)}

Where rate is the percentage increase or return you expect per period, expressed as a decimal. In this case, 9% would be entered as ".09". The result is how many periods it'd take at a constant rate you choose to quadruple, or 4x.

## Using the Quadrupling Time Calculator

To use the quadrupling time calculator, enter how quickly a quantity is gaining or appreciating. Negative returns or percentages show how many periods in the past the number was 4x as high.

Also, try the doubling time calculator and tripling time calculator.
