Hey Product Hunt! 👋 I built FIREmap because every FIRE calculator I tried had the same problems they ignored kids, couldn't be shared, and gave no context on what the numbers actually meant. A few things I'm proud of: **Shareable URLs** — your exact inputs (age, income, expenses, savings, return rate) are encoded in the URL. Adjust your numbers, hit "Share Results", and paste it to your partner. They open it and see exactly what you see. No accounts needed. **Dependents** — most calculators assume you're single. FIREmap adjusts your monthly expenses based on the number of kids, which meaningfully changes your FIRE number. **Education built in** — the calculator is one tab. The learn section covers Lean, Fat, Coast, and Barista FIRE with real numbers, not vague descriptions. The 4% rule page explains the Trinity Study and where it breaks down for long retirements. It's completely free — no sign-up, no paywall. I want it to stay that way. Would love honest feedback: what's missing? What assumption is wrong? What would make you actually bookmark and use this?
