Calculadora de crecimiento poblacional

Crecimiento poblacional exponencial N(t) = N0*e^(rt).

Introducción

Population Growth Calculator — Exponential population growth N(t) = N0*e^(rt). Enter Initial population, Growth rate (r, per unit time), Time to get an instant, accurate result.

Fórmula

Exponential population growth model: N(t) = N₀ × e^(rt), where N₀ is the starting population size, r is the per-capita growth rate, and t is elapsed time.

Paso a paso

  1. Enter the Initial population.
  2. Enter the Growth rate (r, per unit time).
  3. Enter the Time.
  4. Click Calculate to see your result instantly.

Ejemplo del mundo real

Example: With Initial population = 100, Growth rate (r, per unit time) = 0.1, Time = 10, the Population Growth Calculator gives Population: 271.8282.

Preguntas Frecuentes

When does exponential growth apply in real populations?
It approximates growth when resources are effectively unlimited, such as early-stage bacterial cultures or a population newly introduced to a resource-rich environment — real populations eventually slow as resources become limiting.
What does a negative growth rate r mean?
A negative r produces population decline (decay) rather than growth, useful for modeling a shrinking or dying-off population.
What inputs does the Population Growth Calculator need?
You'll need to provide: Initial population, Growth rate (r, per unit time), Time. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Population Growth Calculator?
The Population Growth Calculator applies the formula exactly as calculated — Exponential population growth model: N(t) = N₀ × e^(rt), where N₀ is the starting population size, r is the per-capita growth rate, and t is elapsed time. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Population Growth Calculator free to use?
Yes, the Population Growth Calculator is completely free, requires no signup, and runs instantly in your browser.

Acerca de Calculadora de crecimiento poblacional

The Population Growth Calculator uses a real, verifiable formula — Exponential population growth model: N(t) = N₀ × e^(rt), where N₀ is the starting population size, r is the per-capita growth rate, and t is elapsed time. — so results are accurate every time, not an approximation.
