About Calcora
Why we built a calculator suite the way we think calculator suites should be built.
What Calcora is
Calcora is a free, all-in-one suite of calculator tools spanning finance, health, education, tax, unit conversion and everyday life. Instead of hunting across a dozen different sites for a loan calculator, then a BMI calculator, then a GPA calculator, Calcora puts working, accurate tools for all of these — and more — in one clean, fast workspace.
Why we built it
Most calculator sites online are cluttered with pop-up ads, auto-playing video, and multi-step forms that exist to harvest your email address before showing you a number. We wanted something different: a tool that opens instantly, gets straight to the calculation, and respects your time. Calcora was built to be the calculator site we wished existed — fast, clear, and free of noise.
How it works
Every calculator on Calcora runs standard, well-established formulas — things like loan amortization, the Mifflin-St Jeor equation for BMR, compound interest and SIP growth, GPA weighting, and unit conversion tables. Calculations happen instantly as you type, right in your browser, so there's no waiting on a server round-trip for a simple result.
Privacy by default
Calcora doesn't require an account, and nothing you type into a calculator is sent anywhere. Favorites and recently-used tools are saved locally in your own browser, not on a server, so your usage stays yours.
Accuracy and limitations
We aim for accuracy in every formula we ship, but Calcora's results — especially in the finance, tax, and health categories — are estimates for informational purposes, not professional advice. Tax rules in particular vary widely by country and jurisdiction, so the tax tools are explicitly illustrative rather than authoritative. Always check important decisions with a qualified professional. See our Disclaimer for more detail.
Who's behind Calcora
Calcora is built and maintained by RemoteServices100. We're a small, independent team, and we keep improving Calcora based on feedback from people who actually use it — if something's missing or broken, our Contact page is the fastest way to reach us.
