How to Calculate Logistic Growth
What is Logistic Growth?
Logistic growth is population growth that slows as resources become limiting. The S-shaped sigmoid curve contrasts with unconstrained exponential growth.
Step-by-Step Guide
- 1P(t) = K / (1 + ((K-P₀)/P₀) × e^(-rt))
- 2Three phases: exponential, slowing, plateau at K
