calculatricepourcentage.com

calculatricepourcentage.com is a free collection of percentage calculators in French. Every result shows the formula used, calculations run in the browser, and there are 60 corrected exercises from CM2 to seconde with printable PDFs. Tools cover VAT, discounts, successive increases, margins, multipliers, fractions and slope. Free, no signup.

The homepage combines six everyday calculators: percentage of a number, share of a total, percentage change, adding a percentage, removing a percentage, and finding the original value before a change. Dedicated pages go further: VAT excl./incl., discounts and final price, successive increases, margin and markup rates, the multiplicative coefficient, converting fractions to percentages, and slope in degrees.

Each tool explains the formula behind the result and works entirely in your browser: no account, no data sent to a server. Students will find 60 corrected exercises spanning CM2 to seconde, with step-by-step solutions and printable PDF worksheets, plus an Excel guide for teachers and parents. The site is aimed at French-speaking students, shoppers and professionals who need a quick, reliable percentage calculation with the reasoning shown, not just the number. 100% free, no signup, no account required. The project was founded in October 2026 and targets learners in France, Belgium, Switzerland, Canada and other French-speaking regions who study mathematics in French. It is completely free to use and does not require any registration or personal data.
