⛽Fuel Cost Calculator
Calculate the liters of fuel a trip needs and its total cost from distance, consumption (L/100 km) and price per liter — with optional cost splitting between passengers.

About this tool
Estimate what any car trip costs in fuel: enter the distance, your car's consumption in L/100 km and the current pump price. For shared trips, the cost splits evenly between passengers automatically.
liters = distance × consumption ÷ 100 · cost = liters × price per liter
Frequently asked questions
How do I convert from MPG?
US mpg ≈ 235.215 ÷ (L/100km); UK mpg ≈ 282.481 ÷ (L/100km). Divide to get L/100 km and enter it here.
Does this include tolls or wear?
No — fuel only. For a full cost-per-km figure, add tolls, maintenance and depreciation separately.
