Calcrux
Free platform for people who actually run businesses
Calcrux is a free online business calculator platform with 100+ tools for ecommerce sellers, manufacturers, startup founders, and investors. Every calculator runs instantly in your browser — covering 9 countries and 9 currencies — with no account, no paywall, and no limit. Calcrux specialises in business operations where those tools are general-purpose. Each tool includes domain benchmarks, smart insights, and formulas verified against professional standards — not textbook approximations.
Too many business decisions are made on gut feeling because the right tool is behind a paywall, buried in a spreadsheet, or simply doesn't exist. We've already built 100+ precision tools — calculators, simulators, estimators — and are scaling to 500+, each backed by real domain logic: actual fee schedules, ISO manufacturing standards, and verified financial formulas. Anyone on the planet can use them, free, forever. 9 markets, no sign-up →
Love the no-signup approach and the 9-country coverage, super useful for cross-border work. One thing that would take it further for me is a way to save or export my calculation history as a PDF or CSV, so I can share a clear breakdown with clients or teammates without copy-pasting each field.
