How to Calculate Gas for a Trip in Europe

The calculation is simple: use your driving distance, vehicle consumption and the fuel price you expect to pay.

STEP 01

Enter your distance

Use the road distance in kilometres. For a return journey, select the round-trip option.

STEP 02

Add vehicle consumption

Enter litres per 100 km. For example, a vehicle using 6.5 L/100 km needs about 6.5 litres for every 100 km.

STEP 03

Enter fuel price

Use an expected petrol, diesel or LPG price in euros per litre to estimate your fuel budget.

Fuel needed = Distance × Consumption ÷ 100   |   Fuel cost = Fuel needed × Price per litre

Calculate Gas for a European Road Trip

Driving through Europe gives you the freedom to choose your route, stops and travel schedule. Before starting a long road trip, it helps to estimate the amount of fuel you will use and the cost of filling the tank along the way.

What information do you need?

Start with the driving distance between your origin and destination. Then check your car's fuel consumption, normally shown as litres per 100 kilometres (L/100 km). Finally, enter an estimated fuel price in euros per litre.

Example calculation

Suppose your route is 1,200 km and your car consumes 6.5 L/100 km. The estimated fuel requirement is 78 litres. At €1.75 per litre, the estimated fuel cost is €136.50. If the same journey is a round trip, the distance becomes 2,400 km and the estimated fuel requirement and fuel cost double.

Remember tolls and parking

Fuel is not the only driving expense. Depending on your route, you may encounter motorway tolls, bridges, tunnels, ferries, parking fees or road charges. Use the calculator's extra-cost field to include your own estimates.

Fuel prices can vary

Actual prices can differ by country, region, station and road type. Motorway service stations may have different prices from stations away from major highways. For the most useful estimate, enter a price that reflects where you expect to refuel.

Planning a multi-country trip

For a journey through several European countries, you can calculate each major route segment separately using the relevant expected fuel price. Adding the segment costs can give you a more detailed fuel budget.

This calculator is an independent estimation tool. It does not provide live fuel prices, live traffic, route directions, toll quotations or booking services. Verify current prices, road charges and travel restrictions before your journey.

Frequently Asked Questions

Common questions about calculating fuel costs for European road trips.

How do I calculate gas for a trip in Europe?

Multiply your driving distance in kilometres by your vehicle's fuel consumption in litres per 100 km, then divide by 100. Multiply the resulting fuel litres by your expected price per litre.

Can I calculate a round trip?

Yes. Select “Round trip” and the calculator doubles the distance you entered before estimating fuel and cost.

Can I split the fuel cost between passengers?

Yes. Enter the number of passengers. The calculator divides the estimated total trip cost by the number entered.

Does this calculator include tolls?

Yes. Enter your estimated toll and parking amount in the “Tolls + parking” field. It is added to the estimated fuel cost.

Can I use the calculator for diesel?

Yes. Select Diesel from the fuel type menu. The calculator uses a diesel-specific CO₂ factor for its estimate.

How accurate is the result?

The result is an estimate. Real-world fuel consumption depends on speed, traffic, hills, weather, vehicle load, tyre pressure and driving conditions. Fuel prices can also change.
