Fuel consumption calculator
Calculate fuel consumption in L/100 km and km/L, with an optional fuel-cost estimate.
Distance and fuel must cover the same journey or measurement period. The result depends on the accuracy of your entries. Cost uses the price you enter and excludes tolls, parking and other vehicle expenses. No currency conversion is performed.
Calculations run only in this page’s memory. This tool does not send or save your entries or results.
Enter the distance travelled and fuel used over the same period. Add a price per litre if you also want the fuel cost.
How it works
How it works
L/100 km = litres used ÷ kilometres travelled × 100. km/L = kilometres travelled ÷ litres used. Optional fuel cost = litres used × price per litre, in the currency you enter.
Example
40 L used over 600 km gives approximately 6.67 L/100 km and 15 km/L.
