Game math in the open
GameCalc builds interactive calculators for popular games — XP curves, crop economics, marketplace fees — and pairs each one with a short guide explaining the math. Every tool runs entirely in your browser: no accounts, no uploads, no tracking of the numbers you enter.
Where the data comes from
Values come from publicly documented game mechanics and are checked against the live game version. Game patches can change prices and formulas; when they do, we update the affected tools and note it on the page. Game names and mechanics are referenced for identification and commentary under fair use; GameCalc is not affiliated with or endorsed by any game publisher.
Request a calculator
The roadmap is driven by requests. If a game you play has a number you're tired of computing by hand, send it through the feedback form on any page — the most-requested tools get built first.
