The Exponential Decay Calculator is used to solve exponential decay problems. It will calculate any one of the values from the other three in the exponential decay model equation.
The following is the exponential decay formula:
P(t) = P0e-rt
where:
P(t) = the amount of some quantity at time t
P0 = initial amount at time t = 0
r = the decay rate
t = time (number of periods)
