Fuel and tolls for a journey, split between passengers.
Fill in the fields and the result will appear here automatically.
Turns distance and consumption into litres, prices them at the pump and adds tolls. Only what you actually spend on the road is counted: depreciation, wear and tax per kilometre depend on the car and the mileage, and putting a figure on them would pass a guess off as a calculation.
How it works
Formula and logic
Litres = distance ÷ 100 × consumption; cost = litres × price + tolls; the share is that divided by passengers. The return-trip switch doubles only distance. Enter total tolls for the whole route; they are added once. Price per litre and tolls must use the same currency. Split participants are a whole number of at least 1; price, consumption and distance are positive and tolls are nonnegative.
Example
800 km at 7.5 L/100 km and 62 per litre uses 60 litres and costs 3720.
Fields and units

FAQ
Is wear and depreciation included?
No, only fuel and tolls. Cost per kilometre for wear depends heavily on the car and would be a guess rather than a calculation.
How do I count the return journey?
Turn on the return option and the distance is doubled, along with the fuel it needs.
Which consumption figure should I use?
The one you measured yourself. Motorway and city driving differ enough that the manufacturer figure rarely matches a real trip.
Are tolls per direction or total?
Total. Enter what the whole journey costs in tolls, including the way back if you selected a return trip.
