Logistic Growth Simulator

Simulate S-curves with carrying capacity and growth rate

Carrying capacity K

Initial value P0

Growth rate r

Time t

Logistic Growth Formula

Model	P(t) = K / (1 + A e^(-rt))
A value	A = (K - P0) / P0
Inflection level	K / 2

Step-by-Step Example

With K = 1000 and P0 = 50, A = (1000 - 50) / 50 = 19. The curve grows quickly at first, reaches its fastest growth near P = 500, and then slows as it approaches 1000.

Common Uses

Population growth with limited resources.
Product adoption and market saturation.
Biological growth under constraints.
S-shaped learning and spread models.

Frequently Asked Questions

What is logistic growth?▼

Logistic growth starts almost exponentially, then slows as it approaches a carrying capacity.

What is carrying capacity?▼

Carrying capacity is the maximum level the model approaches over time.

What shape is a logistic curve?▼

A logistic curve is an S-shaped curve, also called a sigmoid curve.

Where is logistic growth used?▼

It is used in population modeling, adoption curves, biology, epidemiology, and constrained growth examples.
