How Ajoneuvovero (vehicle tax) in Finland is calculated
Finland's ajoneuvovero has a CO2-based base tax that rises with emissions, from about 53 EUR a year for a clean car up to a cap.
Diesels also pay a driving-power tax by weight; EVs pay a small driving-power component. The calculator uses the CO2 base. Estimate, not tax advice.

Estimate. Not tax advice. The rates in this calculator are illustrative: they reproduce the shape of the charge through 2 self-test cases, but they are not the official schedule, so the amount shown will not match your bill. Use the official source above for that.
Check the arithmetic yourself: how this calculator is verified — the formula behind every derived value, the 2 test cases the engine reproduces, and what the badge does and does not claim. Also available as machine-readable JSON.
