Exponential Growth/Decay Calculator

Online exponential growth/decay calculator.

Exponential growth/decay formula

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.

Exponential growth calculator

Enter initial value (x0):  
Enter growth/decay rate (r): %
Enter time (t):  
Value at time t (x(t)):  

Example 1

x0 = 40

r = 3% = 0.04

t = 80 hours

x(t) = x0 × (1 + r) t = 40×(1+0.03)80 = 425.63

Example 2

x0 = 40

r = 5% = 0.05

t = 80 hours

x(t) = x0 × (1 + r) t = 40×(1+0.05)80 = 1982

Example 3

x0 = 60

r = 3% = 0.05

t = 80 hours

x(t) = x0 × (1 + r) t = 60×(1+0.05)80 = 2973
