About
About Calcxo
Calcxo is an independent reference site for everyday math, finance, and health calculations. We exist because most calculator websites treat the result as the whole story — and we don't think that's good enough.

Who we are
Calcxo is built by a small team with backgrounds in software engineering, finance, and content design. We share editorial ownership of the site and personally review what gets published. We are not a search arbitrage company and we do not white-label other people's calculators.
What we do
We build calculators, then we explain them. Every tool on Calcxo ships with the formula, a worked example, common pitfalls, and when to use a different calculator instead. The goal is for you to leave understanding the answer, not just holding it.
Our standards
How we write, fact-check, source, and update content is documented publicly: see our Editorial Policy, Sources & Methodology, and Review Policy. If anything on the site doesn't meet those standards, we want to hear about it.
Independence
Calcxo is independently funded. We don't accept payment to feature or rank tools, and editorial decisions are not influenced by advertisers. Sponsored content, if it ever appears, will be labeled as such.
