Exponential Population Growth Calculator

Calculate exponential population growth, doubling time, and predict future population sizes.

Population Name *

What would you like to calculate? *

Initial Population (N₀) *

Starting population

Growth Rate (r) *

Per capita growth rate

Time (t) *

Time in appropriate units

Final Population (Nₜ) *

Population at time t

Time Steps *

📈 Exponential Growth Formula: N(t) = N₀ × e^(rt) • Doubling Time: t₂ = ln(2) / r • Growth Rate: r = ln(Nₜ/N₀) / t
