Hey Product Hunt! 👋 I’m super excited to share MyFIRESimulator with you today. As someone pursuing Financial Independence (FIRE), I got tired of existing retirement calculators. They either look like an Excel sheet from 1995, crash my mobile browser, or lack the sophisticated modeling needed for real-world volatility. I wanted to bring institutional-grade Monte Carlo simulations to a free, accessible platform. My main goal was performance and usability. Instead of running heavy calculations on the frontend, the math engine runs on Cloudflare Pages Functions (V8 engine). It crunches over 4.2 million data points (5,000 full Monte Carlo iterations) in under 10 milliseconds at the edge. ✨ Key Features: ⚡️ Instant Monte Carlo: 5,000 iterations for highly accurate success probabilities. 📉 Advanced Withdrawals: Support for Fixed, VPW (Variable Percentage Withdrawal), and Guyton-Klinger strategies. 🌪️ Stress Tester: Inject custom market crashes (e.g., a 30% drop in year 3) to see if your portfolio survives. 🌍 Multilingual: Natively supports 8 languages. 🌙 Dark Mode: Because our eyes deserve a break. 🔒 Privacy First: It's serverless and stateless. We don't save your financial data. It's completely free to use. I built this to scratch my own itch, but I want to make it the most robust free FIRE tool on the internet. I would absolutely love your feedback! Let me know what you think of the UI, what withdrawal strategies I should add next, or if you manage to break the math engine! 😅 Thank you! 🙏
