Exponential Growth Calculator
Solve the exponential growth equation for any missing variable with time-unit switching (sec, min, hrs, days, weeks, months, years).
Use the formula x(t) = x0 × (1 + r/100)^t for exponential growth or decay.
Enter any three values among initial value, rate of change, elapsed time, and final value to solve the fourth.
Elapsed time supports multiple units and is internally converted to years to match rate in % per year.
Initial value (x₀)
Rate of change (r)
% / year
Elapsed time (t)
Final value (x(t))
