Exponential Growth Calculator

Fill in any three to calculate the fourth value:
Initial amount (P0):
Growth rate (r):
Time (t):
Final amount (P(t)):
Initial amount (P0) 390
Growth rate (r) .031 = 3.1%
Time (t) 68
Final amount (P(t)) 3210.38690214

About This Tool

The online Exponential Growth Calculator is used to solve exponential growth problems. It will calculate any one of the values from the other three in the exponential growth model equation.

Exponential Growth Formula

The following is the exponential growth formula:

P(t) = P0ert

P(t) = the amount of some quantity at time t
P0 = initial amount at time t = 0
r = the growth rate
t = time (number of periods)
