SmartMoney77 is a free suite of 32 financial calculators available in 6 languages, built for anyone who wants clear answers about money without signing up for anything. The featured tool is the Latte Factor Calculator (https://smartmoney77.com/en/latte-factor), which shows what a single daily coffee is actually worth if that money were invested until retirement — a small, concrete number that makes long-term compounding easy to feel rather than just read about.
Beyond the Latte Factor, the suite includes a FIRE number calculator for people planning financial independence and early retirement, a compound interest calculator, savings and loan tools, retirement projections, and a What-If Machine that pulls live market prices from Yahoo Finance and CoinGecko so you can ask questions like "what if I had bought this five years ago?" and get a real answer based on real historical data.
Everything runs entirely in the browser. There is no account, no signup, no email capture, and nothing is stored on a server — your numbers stay on your device. The calculators support 22 currencies and the interface is fully translated into 6 languages, so it works for readers well outside the usual English-only personal-finance audience.
For creators, bloggers, and educators, every calculator can be embedded on your own site via a simple iframe, and there is a WordPress plugin for one-click embedding. There is also an optional public MCP endpoint so AI agents and assistants can call the calculators directly.
An honest note on positioning: this is not an AI wrapper or an "AI startup." It is a deterministic, transparent calculator suite — the math is plain math, not a model — with an optional MCP/AI-agent endpoint layered on top for developers who want programmatic access. Pricing is simple: free, forever, with no account required.
