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.
All dollar values are inflation-adjusted to today's dollars (real $). Why?
10th Pctl ?In 90% of simulations, your portfolio ends above this amount
$--
Median ?Half of simulations end above this amount, half below
$--
90th Pctl ?Only 10% of simulations end above this amount (optimistic outcome)
