Success Rate
?Success rate is the share of simulations where you don't run out of money. 95% CI is the Wilson interval — the true rate lies in this range with 95% confidence. At 100 sims the CI is wide (~10%); at 10,000 sims (PRO) it narrows to ~1%. Dollar values shown below are inflation-adjusted.
