How the calculation works
Journey distance is converted to kilometres and doubled for return travel. Fuel or electricity cost is added to optional trip expenses.
Formula: Total trip cost = fuel or charging cost + tolls + parking + ferry + accommodation + food + other costs.
Worked example
A return road trip with £60 energy cost, £20 parking and £120 accommodation totals £200 before other expenses.
What can affect the result?
Route, traffic, weather, real efficiency, charging losses, tariffs, tolls and changing bookings affect actual cost.
Frequently asked questions
When is distance doubled?
Select return only when the entered distance is one way.
