The cost is an estimate based on the steady consumption figure you entered; real driving varies with speed, load and traffic.
- 1Choose the consumption system your car reports.
- 2Enter the trip distance.
- 3Enter the consumption figure and the fuel price per litre or per US gallon.
- 4Read the fuel needed and the estimated cost.
The car needs 300 x 7 / 100 = 21 litres, costing 21 x 1.60 = 33.60. In the other system: 300 miles at 30 MPG uses exactly 10 US gallons, which at 3.50 a gallon is 35.00.
- MPG here is US gallons. UK gallons are larger, so a UK MPG figure entered as-is would understate the fuel needed; convert using the unit converter's volume factors if needed.
- The estimate assumes steady consumption; hills, speed, air conditioning, load and traffic all move the real figure.
- For a round trip, double the distance before entering it.
Most cars display it on the dashboard trip computer. Otherwise, fill the tank, reset the trip meter, and at the next fill divide litres added by kilometres driven, times 100.
About this tool
The Fuel Cost Calculator estimates what a trip will cost in fuel from its distance, your vehicle's consumption and the local fuel price. It works in the two systems drivers actually use: litres per 100 km with distance in kilometres, or US miles per gallon with distance in miles.
