How to calculate logistic population growth
The logistic growth model describes population growth that slows as it approaches a carrying capacity, unlike unlimited exponential growth.
How the calculation works
Population = Carrying capacity ÷ (1 + ((Carrying capacity − Initial population) ÷ Initial population) × e^(−Growth rate × Time)).
Example
Initial population 100, carrying capacity 1,000, growth rate 0.3, time 10: the population approaches but doesn't exceed 1,000, reflecting resource-limited growth.
Frequently asked questions
How is Result calculated?
Result = [Carrying capacity] ÷ (1 + (([Carrying capacity] − [Initial population]) ÷ [Initial population]) × exp( − [Growth rate] × [Time])).

Pro Tips for Logistic Population Growth
- Unlike simple exponential growth, logistic growth explicitly models a maximum sustainable population (carrying capacity) that growth slows toward as it's approached.
- This model is widely used in ecology for populations limited by food, space, or other resources.
Common Logistic Population Growth Mistakes to Avoid
- Using simple exponential growth to model a population that's actually resource-limited, which would overestimate long-term population size.
