Great for carpooling: enter the trip and the number of people splitting the fuel cost.
315 £ ÷ 4 = 78.75 £
Per person = 78.75 £Quick calculations for drivers. Standard formulas for consumption, cost and speed. Instant in-browser calculation, no account, no data sent. Fuel prices are indicative.
The total fuel cost is divided by the number of people to find each one’s contribution:
A 600 km round trip (7 L/100 km, 7.5 per litre) costs ≈ 315; split between 4 people = ≈ 79 each.
Calculate the total fuel cost (distance × consumption ÷ 100 × price) and divide by the number of people. The result is the amount each one pays.
For example, a 600 km round trip at 7 L/100 km and 7.5 per litre costs about 315; split between 4 people that is roughly 79 each.
In friendly carpooling the cost is usually split equally, including the driver. Some groups exempt the driver in exchange for driving and vehicle wear — agree upfront.
You can add the vignette, motorway tolls and parking to the total cost before splitting, for a fair calculation. This calculator covers fuel only.
Genuinely splitting costs among friends or colleagues is common and accepted. It becomes an issue only if you turn transport into a commercial, for-profit activity without permits.
A fair method is to calculate the cost per segment and split each segment only among those in the car for that stretch of road.
Yes. Split between 3–4 people, the cost per head drops dramatically and is often cheaper than the train or coach, especially over medium distances.
There are carpooling platforms (such as BlaBlaCar) that automatically calculate passenger contributions. For a group of acquaintances, this calculator is enough.
