Fuel calculator
How much will your journey cost in fuel?
Estimate the fuel needed and the cost of a trip using your vehicle's fuel economy and the price you pay per litre. Use kilometres or miles, and UK MPG or litres per 100km.
The starting fuel price is an example, not a live quote. Replace it with the price at your chosen station. Your result updates as you change the figures.

How the fuel cost calculation works
The calculator first estimates how many litres your vehicle will use, then multiplies that amount by the fuel price you enter.
- Using L/100km: distance in kilometres × consumption ÷ 100.
- Using UK MPG: distance in miles ÷ miles per gallon × 4.54609 litres per imperial gallon.
- Journey cost: litres required × price per litre.
Where can I find the right fuel price?
Use the price displayed at the station you intend to visit, or check current reported prices before setting off. The live Pick A Pump fuel comparison map can help you compare stations across the Republic of Ireland. Prices can change, so treat a comparison as a guide and check the forecourt price.
What affects the accuracy?
The estimate is only as accurate as the figures entered. Actual consumption changes with speed, traffic, weather, terrain, load, tyre pressure and driving style. A short urban trip may use more fuel per kilometre than steady motorway driving.
For a return trip, enter the total distance for both directions. For a regular commute, multiply the one-way distance by the number of journeys you make.
