Fire Path: Retirement Sim

Fire Path is an on-device retirement and FIRE (Financial Independence, Retire Early) simulator. Model how long your money lasts by backtesting your plan against a century of real market history—then stress-test it with Monte-Carlo simulation. WHAT IT DOES • Historical backtesting across every rolling retirement window using real market return, inflation, and gold data. • Six withdrawal strategies: fixed real, percent-of-portfolio, Guyton-Klinger guardrails, VPW, CAPE-based, and more. • Monte-Carlo simulation for the odds your plan survives, not just a single path. • Save scenarios and compare them side by side—lean vs. aggressive, early vs. late. • Export your numbers to JSON. PRIVATE BY DESIGN Every simulation runs entirely on your device. There is no account, no sign-in, and your inputs never leave your phone. The free tier shows a single non-personalized banner ad; there is no tracking and no ad personalization. FREE & PRO The free tier includes core historical backtesting. A one-time Pro purchase unlocks all six advanced withdrawal strategies, scenario saving and compare, Monte-Carlo simulation, JSON export, extended market data, and removes ads. One purchase, yours forever—no subscription. For educational and informational purposes only. Fire Path is not financial, investment, or tax advice, and past performance does not guarantee future results.
