## Quadrupling Time Formula

The quadrupling time formula is:

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.
