Keep FEHB after 65ⓘ
🏥 Most FERS retirees keep FEHB alongside Medicare Part B from 65 — both premiums are modeled unless you untick "Keep FEHB after 65".
Premiums are modeled from retirement onward (employer-covered before) and added to your spending target automatically.
IRMAA uses income from two years earlier and is included in costs. Enter prior MAGI below if the lookback precedes the plan.

Historical Stress Test
Your plan, retired into history's worst starting years — real S&P 500 + inflation sequences instead of random simulations
Equity Shareⓘ60%
30%100%

Run in today's dollars: historical real returns (S&P 500 total return minus CPI, approximate published data 1928–2024), your income streams and spending deflated by your inflation assumption. Years past the dataset fall back to your expected real return. Taxes and HSA handled as in the Monte Carlo model.

Longevity Risk
Same plan, longer life — Monte Carlo success if you outlive your life-expectancy setting. Longevity is the one retirement risk you can't rebalance away.

Survival odds are approximate, from the SSA period life table for a 65-year-old (unisex average; "either spouse alive" odds when the spouse module is on). Your life-expectancy slider row is highlighted.
