About Calcul Heure

Calcul Heure is a French-language work-hours calculator. Users enter a start and end time and the tool instantly displays the total in hours:minutes and decimal format, with support for multiple shifts per day, automatic overtime detection using French legal thresholds (35h/week baseline, plus 25 percent for hours 36 to 43 and 50 percent from hour 44), night-hour isolation (default 21:00 to 06:00), salary estimation from an hourly rate, and CSV/PDF export. The site states plainly that it is free, requires no registration, and that all calculations happen locally in the browser, with nothing sent to a server, which it frames as GDPR-compliant. The interface also includes a calculation history stored locally and current French SMIC minimum-wage reference data.

The free plan in practice

What you can actually do on Calcul Heure's free plan (No account required, fully client-side, no usage cap), where it stops, and when it's worth paying.

100% local, in-browser processing, no server upload

When to upgrade to a paid plan

Stay on the free plan while you're comfortably under the free plan's limit (No account required, fully client-side, no usage cap). It's worth moving to a paid plan once you consistently bump into that ceiling, need to remove branding, or want features the free tier holds back.
