Exponential Growth & Decay Calculator

Our free online exponential growth calculator computes exponential growth or decay rates with the help parameters like time period (t), growth rate (r), & Initial value (x) and exponential growth formula.

Exponential Growth Rate Formula

x(t) = x0 × (1 + r) power of (t)

x(t) = x0 × (1 + r) t

x(t) is the value at time t.

x0 is the initial value at time t=0.

r is the growth rate when r>0 or decay rate when r<0, in percent.

t is the time in discrete intervals and selected time units.


x0 = 50

r = 4% = 0.04

t = 90 hours

x(t) = x0 × (1 + r) t = 50×(1+0.04)90 = 1706
