Trip Cost Calculator

Multiply distance by average consumption (L/100 km), divide by 100 to get the litres needed, then multiply by the fuel price. The result is the trip’s fuel cost.

Litres = distance (km) × consumption (L/100 km) ÷ 100. For example, 300 km at 7 L/100 km needs 300 × 7 ÷ 100 = 21 litres.

At 7 L/100 km and a price of 7.5 per litre: 21 litres × 7.5 = about 157.5 one way, double for a round trip.

No, the calculator covers fuel only. In Romania add the rovinieta, and in other countries the motorway tolls and vignettes, which can be significant.

Besides fuel, the real cost includes wear (tyres, oil, servicing), insurance and depreciation. These usually add another 30–50% on top of the fuel cost.

It depends on distance and the number of passengers. For a single person the train is often cheaper; for 3–4 people a shared car becomes competitive. Compare with the split-cost calculator.

Drive at a steady, moderate speed, split the cost with passengers, refuel at cheaper stations off the motorway and plan the route to avoid detours.

Use the current price at your usual station. In Romania, petrol and diesel typically hover around 7–8 per litre, but check the day’s value.
