Fuel cost calculator for car journeys
Estimate petrol or diesel costs using miles, UK MPG and price per litre. Add tolls, parking and a return journey, then split the total.

Distance, consumption, price. Then the extras.
Fuel needed equals distance multiplied by consumption in L/100 km, divided by 100. Multiply the fuel by its unit price, add tolls and parking, then divide by the number of people. MPG and miles are converted before calculating.
This is an estimate, not a route planner. It does not fetch live prices or calculate tolls. Enter the full trip's extra costs; wear, depreciation and time are not included.
