What it calculates

The “Geometric Brownian” calculator computes E[S_t] from 3 parameters: s₀, μ (drift), t (yrs).

A core calculation for studying, engineering tasks, and checking solutions.

Example calculation

With parameters S₀ = 100, μ (drift) = 0.05, t (yrs) = 1 the result is 105.13 (E[S_t] = S₀·e^(μ·t)).
