Work out the trip price and liters needed based on distance, your car's consumption and fuel price — with monthly/yearly costs.
| Step | Formula |
|---|---|
| Liters | (distance ÷ 100) × consumption (l/100km) |
| Price | liters × fuel price (€/l) |
| Monthly/yearly amount | trip price × number of trips (× 12 for the year) |
Actual consumption depends on driving style, traffic conditions, temperature and load — manufacturer l/100km figures are often lower than real city consumption.
Most accurate — calculate it from an actual full tank (liters ÷ km driven × 100). Manufacturer WLTP figures are usually 10–20% lower than real city consumption.
Yes, if you use your personal car for work — see the mileage compensation calculator to work out the compensation amount.
Steady speed, correct tire pressure, removing unnecessary weight/cargo and regular servicing can cut consumption by 5–15%.
