About Calccura
Every calculator on the internet seems to be one of two things: a wall of ads with a calculator hidden somewhere in the middle, or a "modern" app that hides the answer behind a login wall.
Calccura is neither. It's a growing collection of focused, no-signup calculators built for the way people actually use them — from a phone, in a hurry, needing an answer right now.
Everything updates live as you type. No submit buttons. No modals. No email captures. No "unlock premium." Just fast, accurate numbers, clearly explained.
Who made this
Calccura was built and is maintained by Calccura in United Kingdom. It's a small, independent site — not a big publisher or bank.
How it's built
All calculators run entirely in your browser. Numbers never touch a server. The site uses React, TypeScript and TanStack Start. Hosting and admin backend are on Supabase.
How we make money
Calccura is funded by display ads through Google AdSense. Adverts are clearly labelled and never replace calculator answers. We do not sell data — ever.
What we believe in
- Answers first. The result should be visible by the time you finish typing the first input.
- Formulas are public. Wherever practical, we show how each calculator works on the page.
- Accessible. Keyboard-friendly, readable contrast, works on slow connections and tiny phones.
- Minimal data. Calculators run locally. We don't ask for what we don't need.
- Honest about limits. Every calculator page carries a disclaimer — results are estimates, not advice.
If a calculator is wrong or missing, tell us — that's how the list grows.
