Are AutoSuivi calculators free?

Yes. Registration tax, malus, inspection, email reminder, TCO, trip cost and loan / lease can be used without an account. The AutoSuivi logbook then stores history and reminders.

Which car tools are available?

You can estimate 2026 French registration tax, CO₂ and weight malus, the next inspection date, an email reminder, total cost of ownership, a trip cost, and a loan or lease payment.

Do I need to sign up?

Not for a one-off calculation. A free account is useful to save the vehicle, documents and due-date reminders.

In which order should I use the tools before buying?

Registration tax (Y1 + fixed fees, plus malus if first French registration), then TCO over 3 to 5 years, then loan / lease if you finance. Trip cost compares petrol vs electric. Inspection applies once the car is already on the road.

Do the results replace an official quote?

No. They are educational estimates from public scales (registration, malus, inspection) or standard formulas (TCO, energy, monthly payments). A dealer, insurer or the ANTS / SIV service remains the contractual source.

What method sits behind these calculators?

Registration tax, malus and inspection

The 2026 registration simulator uses horsepower rates published by Service-Public (Y1 tax by region, Y4 €11, Y5 €2.76). Malus is added only on first registration in France.

The 2026 CO₂ & weight malus follows the tax code (thresholds 108 g/km and 1,500 kg, cap €80,000). The next inspection follows the rules: first test at 4 years for a passenger car, then every 2 years.

TCO, trip, finance

TCO adds depreciation (age curve), energy, insurance and servicing, per km. Trip cost isolates energy for one journey (litres or kWh) — tolls and wear excluded.

The loan / lease simulator computes a monthly payment from the rate you enter. It is not a bank APR or a commercial offer: always compare with the contract.

Example sequence before you buy

Compact SUV 1,620 kg, 128 g/km, €32,000. 1) Registration tax: Y1 for your region + malus if the car is new. 2) TCO over 5 years at 15,000 km/year. 3) If financed, 60-month loan vs lease. 4) Commute trip to judge petrol vs electric. The four figures together beat a list price.

Example once the car is on the road

Next inspection date, yearly servicing budget, weekend trip cost. The AutoSuivi logbook then keeps invoices, mileage and reminders — which the calculators do not store until you have an account.

Shared limits. Registration (regional Y1, Y4, Y5), malus and inspection rules: texts in force in 2026, subject to change. TCO and trip: standard formulas, not a trade valuation or a charger receipt. Loan: theoretical monthly payment (monthly compound interest), excluding borrower insurance and arrangement fees.
