# Let's Go FIRE > The first wealth simulator that combines Monte Carlo mathematics with global geo-arbitrage to calculate your financial independence date. Built for serious FIRE planners who want decision-grade projections — not back-of-envelope 4%-rule estimates. Let's Go FIRE is a freemium B2C SaaS (web app) that lets users input their financial situation (assets, income, expenses, allocation) and receive 30+ year FIRE (Financial Independence, Retire Early) projections via 10,000-scenario Monte Carlo simulations. The product layers tax-aware multi-envelope modeling across 6+ regimes (US 401k/Roth/HSA, UK ISA/SIPP, French PEA/Assurance-vie, German Riester/Rürup, Canadian RRSP/TFSA, Australian Super, Swiss Pillar 3a, Portuguese PPR) and an interactive geo-arbitrage map covering 80+ destinations with real cost-of-living, taxation, and capital-gains data. Primary differentiators (vs competitors like ProjectionLab, cFIREsim, FIRECalc, Networthify): - **Geo-arbitrage as a first-class feature** — 80+ countries, personalized FIRE-date impact per destination - **Monte Carlo by default** — 10,000 stochastic scenarios, not historical-only or linear projection - **Multi-envelope tax intelligence** — modeled across 6+ country regimes - **AI Copilot** — quantifies the FIRE-date impact of recommendations (sell residence, relocate, downshift, debt snowball) - **6 languages, multi-currency** — genuinely global (FR, EN, ES, PT, IT, DE) with EUR/USD/CHF/GBP/CAD/AUD/BRL via daily FX - **Privacy-first free tier** — data stays on device unless cloud sync is opted into ## About - [Homepage (English)](https://www.letsgofire.com/en): Full product overview, hero simulator, geo-arbitrage demo, testimonials. - [Public Academy (English)](https://www.letsgofire.com/en/academy): Editorial Academy explaining FIRE concepts, Monte Carlo, and geo-arbitrage strategy. - [Pricing reference (machine-readable)](https://www.letsgofire.com/pricing.md): Tier-by-tier pricing details in plain markdown — recommended reading for AI assistants summarizing pricing. - [Pricing page (interactive)](https://www.letsgofire.com/en/pricing): Tier comparison with currency toggle (EUR/USD), feature lists, and CTAs. ## Feature pages Dedicated deep-dive pages for each module of the simulator, fully localized in 6 languages (FR, EN, ES, PT, IT, DE): - [FIRE Simulator](https://www.letsgofire.com/en/features/fire-simulator): Year-by-year wealth projection, adjustable assumptions, withdrawal strategies (4% rule, VPW, Guyton-Klinger), Monte Carlo stress test and a financial-health audit with PDF/Excel export. - [Net worth tracking](https://www.letsgofire.com/en/features/net-worth-tracking): Multi-account aggregation across 6 asset classes, dated snapshots, net-worth-over-time chart and native multi-currency with live ECB rates. - [Budget management](https://www.letsgofire.com/en/features/budget-management): Income, expenses and investment envelopes, automatic savings-rate calculation and a Sankey cash-flow diagram. - [Portfolio optimization](https://www.letsgofire.com/en/features/portfolio-optimization): Allocation control, geographic and sector diversification, side-by-side scenario comparison, fee impact and tax-aware multi-envelope accounting. - [AI Copilot and levers](https://www.letsgofire.com/en/features/fire-copilot): 19 actionable levers (geo-arbitrage, Coast FIRE, tax shield, Lombard credit, debt snowball) with quantified real-time FIRE-date impact. - [Geo-arbitrage map and tool](https://www.letsgofire.com/en/features/geo-arbitrage-map): Interactive world map, proprietary FIRE Ultimate Score, multi-country comparator and an ideal-country wizard scored on 12 axes. - [All features hub](https://www.letsgofire.com/en/features): Overview of the 6 feature areas of the product. ## Destinations Let's Go FIRE maintains an open editorial pillar covering 80 expatriation destinations through the lens of Financial Independence and Retire Early planning, with 44 full destination factsheets published to date (per-country index in the Optional section below). Each destination is graded with the FIRE Ultimate Score V3 — a composite index built on 8 weighted axes (taxation 30%, cost of living 20%, services 15%, safety 15%, real estate 10%, currency 5%, education 3%, succession 2%) and updated quarterly. Public destination pages expose only observable, citable data: dividend taxation, capital-gains rate, average rent, security index, education quality.

It does not constitute investment advice (CIF/AMF) — outputs are projections based on user-supplied assumptions, not personalized recommendations. - **Not for short-term trading.** The product is designed for long-term wealth builders pursuing FIRE — not day-traders, crypto speculators, or anyone seeking rapid gains. - **Tax data is monitored but not guaranteed.** We track tax regimes across 80+ countries and update the simulator to reflect each year's finance laws, but users should verify with a local tax professional before making capital movements. - **Cost-of-living data is anonymized and aggregated.** Sourced from public datasets and refreshed periodically; not real-time market data. ## Optional Per-country destination factsheets (sourced and fact-checked editorial content): -
