Estimate Your French Ecological Malus Instantly

The malus écologique is a French registration penalty applied at the point of first registration to vehicles with high CO2 emissions or significant kerb mass. It is not an annual tax — it is paid once, when the vehicle receives its French carte grise. For high-emission or heavy vehicles the amounts can run to thousands of euros, so understanding the calculation before you sign a purchase order can save real money.

From 2026 the malus has two distinct pillars. The CO2 malus applies a progressive scale starting at 108 g/km. The mass malus (malus au poids) applies marginal euro-per-kilogram bands above the weight threshold for mass in running order. The two components are calculated separately and then combined, subject to a joint legal cap. Certain categories — pure electric vehicles, vehicles adapted for disabled drivers, and families meeting specific criteria — are generally exempt from one or both charges.

Handytool runs the malus écologique calculation entirely inside your browser. No vehicle data, no email, no sign-up — just enter your numbers and get an instant estimate.

The CO2 scale is approximated for planning purposes; the official Direction Générale des Finances Publiques table has a line entry for every gram. For the precise amount due at registration, always consult the official bareme or a certified registration agent (mandataire). Treat this estimate as a useful sanity-check when comparing vehicles rather than an official billing notice.
