Exponential Growth Calculator

Exponential growth and decay describe processes where the rate of change is proportional to the current value. Growth occurs when the rate is positive (population growth, compound interest, viral spread)

The calculator uses the standard published formula for exponential growth. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: Growth: P(t) = P₀ × e^(rt), r > 0. Each step in the calculation is shown so you can verify the result manually.
