3.9 Monte Carlo Simulations

Monte Carlo simulations model thousands of possible futures instead of just one average. This article explains how the simulation works and when to use it.

The post walks through base case, worst case, and best case scenarios to demonstrate how volatility and allocation affect financial planning.
