### 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*) = *x*_{0} × (1 + *r*)^{ t}

*x*(t) is the value at time t.

*x*_{0} 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.

## Example

*x*_{0} = 50

*r* = 4% = 0.04

*t* = 90 hours

*x*(*t*) = *x*_{0}* *
× (1 + *r*)^{ t} = 50×(1+0.04)^{90} = 1706
