FIRECalc: The Custom Engine for Financial Independence Are you on track to retire early? Or are you just guessing? Most retirement apps rely on elementary math like the "4% Rule," assuming you will withdraw the exact same amount every year. FIRECalc was designed to customize your retirement runway in a way that other calculators miss by running thousands of market simulations against your specific budget, all with a sleek and easy to use interface. WHY UPGRADE TO PREMIUM? The base app includes powerful features like investment tracking, budget tracking, growth plans, 5 year retirement Burndown optimization, and government aid calculators including Medicaid and SNAP (food stamps). But when you upgrade to FIRECalc Premium, you unlock a custom FIRE Burndown Engine that acts as your personal financial pilot: Smart Drawdown Strategy: We don't just tell you if you can retire; we tell you how. Our engine automatically puts your withdrawals in the most effective order (Cash, Roth, 401k, Brokerage, Crypto, HELOC) to minimize taxes and maximize longevity. Prefer your own approach? Switch to Custom and drag accounts into any order you like. Tax-Aware Planning: Every year of your plan is calculated with taxes in mind, so you see what you actually keep, not just what you withdraw. Definitive Answers: Get data-backed answers to your most important questions: What is my exact Retirement Age? What if I work 1 more year, or 1 less? What is my safe Annual Budget? And precisely How Long Will It Last? Unlock Hidden Income: Unlike traditional calculators, we factor in potential Government Aid (like Medicaid and SNAP for all 50 states) during your "gap years," effectively extending your portfolio's life. Just turn on "Include Aid in FIRE?" and FIRECalc plans your withdrawals to keep your income under aid limits. HELOC Strategy: Home equity loan draws don't count as income. When aid is on, FIRECalc can draw from a HELOC to help you stay under Medicaid and SNAP limits without triggering a taxable event. Don't plan to use aid? Turn it off with one tap. Secure Cloud Sync: Your data syncs securely across all your Apple devices via iCloud. Your plan is safe even if you lose your device. KEY FEATURES Multi-Asset Tracking: Full support for 401k, Roth IRA, HSA, Crypto, Metals, and Real Estate. Flexible Scenarios: Test "Lean FIRE" vs "Fat FIRE" budgets instantly. Download FIRECalc today. You may be closer to freedom than you think. NOTE: this app is not intended to impersonate the identity of any government agency. It is not possible to apply for SNAP/EBT Benefits or Medicaid/ACA/Medicare via this app. This app is only intended to give an estimated calculation only based on public information on federal and state websites.
