[WARNING] Is your early retirement plan prepared for the worst-case scenario? Most calculators assume a perfect 5% annual return. But the real stock market doesn't work that way. Market crashes and the "Sequence of Returns Risk" can destroy your portfolio in the first decade of retirement. "FIRE Survival" is a high-precision Financial Independence, Retire Early (FIRE) simulator. We don't just calculate average returns—we run advanced simulations considering actual market volatility to determine your exact "Survival Rate." See the Bottom 5% Worst-Case Scenarios and build an ironclad wealth management plan that lasts your lifetime. Whether aiming for Lean FIRE, Fat FIRE, or Side FIRE, our app acts as your ultimate personal finance compass. ◆ WHO IS THIS APP FOR? - Anyone aiming for Financial Independence and Early Retirement. - Retail investors tracking their retirement number and savings rate. - Retirees worried about inflation, recessions, or running out of funds. - People exploring "Side FIRE" (working part-time or freelance). - Finance geeks analyzing safe withdrawal rates, dividends, and portfolio survival rates. ◆ CORE FEATURES ① [High-Precision Wealth Simulation] Input your current age, net worth, annual income, savings rate, expected return, and inflation rate. Visualize not only the median asset growth but also the "Worst 5% Scenario." Know exactly what happens if the economy crashes the day you retire. ② [Side FIRE & Total FIRE Comparison Mode] Not ready to quit completely? Toggle instantly between "Total FIRE" (zero active income) and "Side FIRE" (earning active income through side hustles). See how a small monthly income drastically improves your portfolio’s survival rate. ③ [DANGER ZONE & Solutions] If your plan has a high risk of going bankrupt early, our "Danger Zone" triggers. The app reverse-engineers your data to provide exact solutions. It tells you exactly: - "Work for 3 more years" - "Save an additional $20,000" - "Reduce annual spending by 10%" Stop guessing and know what steps you need to take today. ④ [Intense Economic Stress Testing] What if the S&P 500 crashes by 15% for three consecutive years right after you leave your job? What if inflation unexpectedly spikes? Run extreme stress tests with a single tap to see if your portfolio is recession-proof. ⑤ [FIRE Personality Insights] Based on your inputs, the app classifies your strategy into 5 unique profiles (e.g., "Fortress," "Lean," "Fragile"). Understand the structural strengths of your finances and get tailored advice. ◆ WHY CHOOSE "FIRE SURVIVAL"? Standard calculators are dangerous because they ignore volatility. If a bear market hits after you retire, withdrawing money while your assets are depleted cripples your portfolio. "FIRE Survival" simulates genuine market fluctuations, helping you build a portfolio that thrives during economic recessions. ◆ PREMIUM SUBSCRIPTION While the core simulation is free, unlocking our Premium Plan gives you ultimate analytical power: - Ultra-High Precision Mode (3,000 extensive simulation trials for maximum accuracy). - 100% Ad-Free Experience. - Save & Track unlimited simulation histories to compare scenarios. - Unlock advanced "Danger Zone" metrics. *Subscriptions can be cancelled anytime via App Store settings.* Your financial freedom is not a game. Plan it with absolute precision. Download "FIRE Survival" today and take the first concrete step toward a worry-free early retirement! --- [Disclaimer] Results provided by this application are for informational and educational purposes only and do not constitute professional financial advice.
