Kelo

Kelo is a privacy-first FIRE retirement planner that runs 100,000 Monte Carlo simulations on your iPhone — no signup, no bank logins, no tracking. Most retirement calculators use a single assumed rate of return and call it a day. Bank-connected trackers want your login credentials and sell your data. Neither helps you stress-test early retirement against the real history of markets. Kelo is different. Every simulation runs on 98 years of historical US market data (1928 to present) using the same block-bootstrap method researchers use for retirement research. Nothing leaves your device. WHAT YOU GET • Rich, Broke or Dead? — actuarial survival overlay shows the 3-way split (funded, broke, deceased) for every future year, so you see if your money will outlast you — powered by SSA Period Life Tables (Free) • 100,000 Monte Carlo runs on your iPhone • Full FIRE, Barista FIRE, and Coast FIRE modes • Three withdrawal strategies: Constant Dollar, Guyton-Klinger guardrails, and Floor / Ceiling • Social Security claim-age modeling at 62, 67, and 70 — with COLA and NPV delta • ACA MAGI cliff visualization with premium estimates and subsidy waterfall • Side-by-side scenario comparison (Pro) • PDF scenario export (Pro) • Home-screen widget showing your FIRE progress ring • Optional encrypted iCloud sync — off by default • Compare to History — run your plan against 1966, 2000, or 2008 cohort returns to stress-test SORR (Free) WILL YOUR MONEY OUTLAST YOU? For most FIRE planners, a long, well-funded retirement is far more likely than running short — the antidote to one-more-year anxiety. Rich, Broke or Dead overlays SSA actuarial life tables to split each year into alive & funded, alive & broke, and deceased. Free. Based on public actuarial data, not a personal health prediction. WHAT IF YOU RETIRED IN 2000? 1966 and 2000 are the FIRE community's worst-case SORR benchmarks — stagflation and the dot-com+GFC sequence. Compare to History overlays your exact plan on those returns. One verdict line on your Monte Carlo fan: green if the cohort survived your horizon, red if it depleted. No fabricated returns. Free. HOW IT WORKS 1. Enter your portfolio, savings rate, and target spending 2. Pick a FIRE mode and stock / bond allocation 3. Run the simulation — see your success rate, median trajectory, and percentile fan chart 4.
