About Xearno Tools

Xearno Tools is a growing bench of 56+ free calculators for money and business decisions — income tax across two dozen countries, loans and mortgages, currency, unit economics, pricing, and the everyday math people actually search for.

Every tool does three things: it computes the number with a tested, published formula; it reads that number the way an experienced operator would, with benchmarks and the traps to watch; and it shows its methodology and data basis in the open. Nothing here is a black box.

Why it’s free, and why you can trust the numbers. Most calculator sites are lead-generation businesses — their math exists to route you toward a loan, a card, or an advisor who pays them. We’re different by construction: Xearno Tools is made by the team behind the Xearno app, a personal-finance app that treats your money as a living fortune rather than a spreadsheet. We make an app, not loans — so there are no ads, no affiliate offers, and no reason for any number to point you anywhere.

Built for people and for AI. Every tool is also callable by AI assistants and agents over an open API and an MCP server, so an assistant can compute reliably instead of doing financial arithmetic in its head. See the agent docs.

These tools are for information and education. They are not financial, tax, investment, or legal advice — see our terms & disclaimer and privacy note.
