🏖️ Retirement Simulation Tool Monte Carlo · Thousands of runs

Project whether your retirement money lasts through your plan. We simulate random returns with your assumptions and report the success probability, ending wealth percentiles, and depletion age distribution.


Return assumptions (normal dist)

We model annual steps. Contributions are added yearly, then growth applies. In retirement, spending escalates by inflation each year.

Method

Monte Carlo using normal returns with your mean/vol inputs. We track the corpus from age to , add yearly contributions until retirement, and withdraw inflation‑linked spending after retirement.
