How Fordonsskatt (vehicle tax) in Sweden is calculated
Sweden's fordonsskatt applies a higher malus to new petrol and diesel cars in their first three years, based on CO2 per km, then drops to a lower standard rate.
Diesels carry an environmental factor and fuel supplement. The calculator uses an illustrative malus-era CO2 table. Estimate, not tax advice.
Worked example
ShowHide the full working: 2 inputs, 3 computed steps
| Inputs | |
|---|---|
| CO₂ (g/km) | 100 |
| Bilens ålder | 1 |
| Computed by the engine | |
| I Malus ✓ pinned | 1 |
| Koldioxidbelopp ✓ pinned | 2,675 SEK |
| Fordonsskatt / år ✓ pinned | 3,035 SEK |
Every computed row comes from the engine, run on the inputs above. Rows marked ✓ pinned are also fixed by a published self-test, so a change to the model that moved them would fail its own tests.
