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
