The Malthusian Growth Model calculator computes the estimated future size of a population (P) based on the current population (P0), a growth exponential factor (r) and the a period of time (t).
INSTRUCTIONS: Choose units and enter the following:
Future Population Size (P): The calculator returns the future population (P).
The Malthusian Growth Model is basically an exponential growth model based on a constant rate of change. It is widely regarded in the field of population ecology, but populations cannot grow indefinitely. This model should only be used for short time periods of about 10 to 20 years.
The formula for the Malthusian Growth Model is:
P = P0⋅e(r⋅t)
