Exponential Growth Decay Calculator

Model growth or decay over periods with compounding behavior.

Exponential Growth Decay Calculator models values that change proportionally over time. It is useful for population, finance, and radioactive decay style problems. The tool computes future value using growth/decay rates and time horizon. Use it to compare long-term behavior under different rate assumptions.
