About This Launch
Calculatrice Pourcentage is a free online percentage calculator in French. It handles the percentage of a number, increases and decreases (rates of change), discounts, VAT (HT/TTC) and margins, showing the formula and step-by-step working with each result. It also includes explanations and corrected exercises for students, and works on mobile and desktop with no signup.
Why I Built This
French speakers constantly need quick percentage math for sales discounts, VAT and pay raises, and most calculators just give a number. We built a simple tool that shows the formula and method too, so people learn while they calculate.
