AllCalculs is a free collection of more than 320 online calculators for everyday questions: money, percentages, dates, work, home, health, maths and more. Every calculator shows the result as you type, the formula, each step of the working and a worked example.
What we stand for
- Free, with no sign-up. Every tool works straight away in your browser.
- Transparent. We show the formula and the steps so you can check the result.
- Bilingual. Every calculator exists in English and French, with French rules where they differ (VAT rates, notary fees, payroll hours).
- Private. The values you type stay in your browser, and files (PDFs, images) are never uploaded to our servers.
- Kept up to date. Official figures that change (usury rate, minimum wage, tax scales) are checked every quarter.
How we build our calculators
Each calculator is written and tested against worked examples before it goes online. Texts are drafted with the help of AI tools and reviewed before publication. Results are estimates for information only and are not financial, tax or legal advice.
