Travel Fuel Cost Calculator

Calculate the fuel cost of a journey from distance, consumption and price.

About Travel Fuel Cost Calculator

Consumption quoted as litres per 100 km multiplies directly by distance once divided by 100. Splitting the total across passengers gives the per-person figure that makes driving comparable with a train or flight ticket. Fuel is the largest variable cost of a road trip, and the per-kilometre figure is what mileage reimbursement and cost-sharing conversations turn on.

Formula

Travel Fuel Cost

Litres = distance × consumption ÷ 100; cost = litres × price per litre

consumption
Litres burned per 100 km
price
