About Calcuto

What Calcuto is

From mortgages and loans to BMI, unit conversions, dates, and study grades, every tool shares the same clean, keyboard-friendly interface and a fully-rendered page you can read, print, or link to. There are no accounts and no paywalls.

Finance calculators support multiple currencies, so you can work in the money you actually use.

Built to be fast and private

Calcuto respects your privacy by design: there are no user accounts, and your recent calculations and preferences — such as your chosen currency and theme — are stored only in your own browser, never on a server tied to your identity. Our Privacy page explains this in full.

The entire library is generated from a single catalogue of calculators, so every tool behaves consistently and new ones meet the same standard automatically.

Accuracy and honesty

We take care to use correct, well-established formulas and to label inputs clearly. Even so, results are for general information and are estimates — especially for finance and health tools, where real-world outcomes depend on your specific circumstances. Always double-check important figures, and see our Disclaimer before relying on any result.
