## Growth Rate Percent Formula

The following formula is used by the calculator above to determine the growth rate in percent of a value over time.

*x*(*t*) = *x*_{0} Ă— (1 + *r*)^{ t}

Where r is the growth rate in percent. This equation can further be simplified to the following:

r = (*x*(*t*) – *x*_{0})^^{ 1/t} – 1

- Were X(t) is the final value
- X0 is the initial value
- t is time in years

## Growth Rate Definition

A growth rate is the rate of increase of a value. In other words, what percentage of a value increases per time period.

## How to calculate a growth rate?

How to calculate a growth rate percent

**First, determine the initial final values**This will be the values at time t=0.

**Next, measure the time elapsed.**After the time has passed, measure the final value.

**Finally, calculate the growth rate percent.**Enter the values from steps 1 and 2 into the formula to calculate the growth rate percent.

## FAQ

**What is a growth rate percent?**

A growth rate percent is the percentage increase of an exponential function. That is the rate increase of a value over each unit of time.

**Can growth rate percent be negative?**

Absolutely, a negative growth rate equation will yield values that approach 0 but never reach it.
