What does this tool do?

Fuel cost per kilometre is the price of a litre multiplied by consumption per kilometre. This calculator gives the per-kilometre and per-100-km cost, plus the fuel and cost for a chosen trip.

The Formula

Cost per km = Fuel price × (L/100 km ÷ 100); Trip cost = Cost per km × Distance

Frequently Asked Questions

How do I convert MPG to litres per 100 km?

Divide 235.215 by the MPG figure. For example, 30 MPG is about 7.8 L/100 km. Use the US gallon figure, since UK MPG uses a larger gallon.

Does this include maintenance and tyres?

No, it covers fuel only. Add servicing, tyres, insurance and depreciation if you need a full cost per kilometre for reimbursement.
