๐Ÿ–๏ธ Retirement Simulation Tool Monte Carlo ยท 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.
