Enter the population size, rate of increase of population, and the total change in population over the time period to determine the carrying capacity.

## Carrying Capacity Formula

The following formula is used to calculate a carrying capacity.

K = r * N * (1-N) / CP

• Where K is the carrying capacity
• r is the rate of population increase
• N is the population size
• CP is the change in population size

## Carrying Capacity Definition

A carrying capacity is defined as a constant that explains how a population grows within a certain area.

## Carrying Capacity Example

How to calculate a carrying capacity?

The first step in calculating a carrying capacity is to determine the rate of population increase. In this example problem, the rate of population increase is found to be 50%.

Next, determine the current population size. For this example problem, the population size will be 5000.

Next, determine the change in population size. In this case, the change in population size is 100.

Finally, calculate the carrying capacity using the formula above:

K = r * N * (1-N) / CP

K = .50 * 5000 * (1-5000) / 100

K = -124957
