Enter any three values—Initial Population (X₀), Rate of Growth (%) (r), or Number of Years (t)—and calculate the missing parameter.
The Population Growth Calculator is a powerful tool designed to estimate population growth over time. Using the population growth formula, it calculates how a population increases (or decreases) based on its initial size, growth rate, and the time period.
Whether you’re analyzing global population trends or estimating growth for a specific area, this calculator provides precise results. It also supports detailed step-by-step calculations.
