# Exponential Growth Calculator

Calculate the Exponential Growth with our free online tool using the input parameters: Initial Value at Time, Growth Rate / Period, Time (No. of Periods)

In this exponential growth calculator, you can determine the growth of a function that increases by a constant percentage at regular time intervals. Simply input the initial value, growth rate per period (in percentage), and the number of periods, and calculate the exponential growth. This tool is useful for analyzing and forecasting the growth of various phenomena that exhibit exponential patterns.

**The variables used in the formula are:**,

`P(t)`

is the final value or population size at time t

`P`

is the initial value or population size at time t = 0_{o}

`r`

is the growth rate per period, expressed as a decimal.

`t`

is the number of periods.

This formula calculates the future value or size of a population that experiences exponential growth over time. The value of `e`

is the mathematical constant approximately equal to 2.71828, and it represents the base of the natural logarithm. By raising `e`

to the power of `rt`

, the formula accounts for the compounding effect of exponential growth.
