Fuel in litres = distance in km × consumption in L/100 km ÷ 100; fuel cost = litres × price per litre. If the outward and return distances are equal, double the one-way distance. Divide the cost by the number of people only if you are sharing fuel costs.

Trip fuel cost calculator

Formula

Fuel used = distance × consumption ÷ 100. Fuel cost = fuel used × price per litre. Distance is doubled only when “Double the distance for the return journey” is ticked.

Fuel only; tolls, parking and other costs are not included.

A 300 km trip using A95 petrol

The one-way distance is 300 km and consumption is 6.5 L/100 km. A95 petrol costs €1.945 per litre: the Lithuanian average published by the Lithuanian Energy Agency (LEA) for 2026-10-23. Prices change daily, so enter today’s price in the calculator.

One way
300 km × 6.5 L/100 km ÷ 100 = 19.5 L; 19.5 L × €1.945/l = €37.93.
There and back
600 km × 6.5 L/100 km ÷ 100 = 39 L; 39 L × €1.945/l = €75.86.
Per person
Sharing fuel costs between 3 people gives €25.29 each.

Calculate the share from the unrounded total cost, then round it to cents.

Which figures should you enter?

Distance (km)

Take the kilometres from your own route planner or odometer. Enter distance in kilometres and consumption in litres per 100 kilometres.

Enter kilometres in “Distance (km)”. Selecting “Double the distance for the return journey” multiplies them by two. For different outward and return routes, enter their combined distance and leave the checkbox unticked.

Your car’s consumption

Use consumption in L/100 km based on your own car’s records. If you do not know it yet, our guide to calculating fuel consumption with the full-to-full method explains which litres and kilometres to include.

Your average consumption helps you budget, but actual fuel use can vary.

Price per litre and number of people

Enter the price you will actually pay per litre after any discounts that apply to you.

Fill in the number of people only if you are splitting fuel costs equally. Include the driver if they are paying a share too. Leaving the field empty means one person; you can enter a whole number from 1 to 9.

The trip fuel cost formula

Fuel needed (L) = distance (km) × consumption (L/100 km) ÷ 100.

Fuel cost (€) = fuel needed (L) × price per litre (€/l).

For the same route there and back, first double the one-way distance. When sharing costs, divide the total fuel cost by the number of people paying. Round only final litres and euros to two decimal places.

To compare your car’s fuel cost over a fixed distance, use the fuel cost per 100 km calculator.

A short checklist before you travel

  • Check whether you entered one-way kilometres or the whole journey, and whether you have counted the return twice.
  • Choose your car’s consumption and the price after discounts. Do not combine one fuel’s price with another fuel’s consumption.
  • Agree who is sharing fuel costs, whether the driver is included and whether the shares are equal.
  • Budget separately for tolls, parking and other expenses: the calculator covers fuel only.

If you are considering a more distant filling station, assess the extra drive separately: is cheaper fuel worth the detour?
