Consumption, distance and pump price

Litres and money for a journey, the share per passenger and what a single kilometre actually costs.

Two situations call for this: budgeting a trip, and splitting the cost fairly between people in the car. The formula is elementary — distance times consumption over a hundred — and the return leg is what gets forgotten.

Manufacturer consumption figures are almost always optimistic. On a motorway they roughly hold; in town, in winter, with air conditioning running, real consumption is 15 to 30 percent higher. Use your own trip-computer figure.

Litres and cost for the whole journey, return leg included
The share per passenger, ready to send to whoever is coming
Cost per kilometre and per hundred kilometres

What to keep in mind

Consumption is averaged; urban driving runs above the official figure and steady motorway driving below it.
Only fuel is counted. Wear, oil and depreciation add roughly as much again to the true cost per kilometre.

FAQs

Which consumption figure should I enter?

Your own, from the trip computer over the last thousand kilometres. The official combined figure understates reality, particularly on automatics.

How much worse is winter?

10 to 20 percent, from warm-up idling, winter tyres and cabin heating. On short urban trips the penalty reaches a third.

How should passengers split the cost?

Divide fuel by everyone in the car, driver included — that is what the per-passenger line shows. Tolls are usually split the same way.

What does a kilometre really cost?

Fuel is about half of it. Adding depreciation, tyres, oil, insurance and tax typically doubles the figure.

Worked example

A 700 km drive with four people

Input: 700 km, 8 l/100 km, fuel at 60 ₽, four passengers

Output: 56 litres, 3,360 ₽, or 840 ₽ each

Note: There and back is 6,720 ₽, so 1,680 ₽ each. Driving alone costs the same in total, which is what makes carpooling worth the coordination.
