What formula is used?

P(t) = P₀(1 + r)^t, where P₀ is initial value, r is rate per period (as a decimal), and t is time.

Does this work on mobile?

Yes. The tool is responsive and works on all devices.

For decay, use a negative growth rate (e.g. -5 for 5% decay per period).

Exponential Growth Calculator

This free exponential growth calculator computes the final value from an initial value, growth (or decay) rate as a percentage, and number of time periods. Use it for finance, population, or science. No sign-up required.

Formula: P(t) = P₀(1 + r)^t
