Consumption, distance and pump price

Litres and money for a journey, the share per passenger and the cost per kilometre, your average consumption per 100 km from a fill-up, and how far the fuel left in the tank will take you.

Fuel for a trip is distance × consumption per 100 km ÷ 100 litres, and litres × price is the cost. 700 km at 8 l/100 km takes 56 litres; at 60 ₽ a litre that is 3,360 ₽, or 840 ₽ each for four people.

The easiest way to find a car's real consumption is a fill-up: fill the tank, drive, fill it again. Litres at the second fill ÷ kilometres × 100 gives l/100 km: 45 l over 520 km is 8.65 l/100 km.

How to use

Choose what to work out: trip cost, average consumption, or range on the fuel left.
For a trip, enter the distance, consumption per 100 km, price per litre and number of people; mark it if you are going there and back.
Read the litres, cost, share per person and cost per kilometre, with the working on one line.

Litres, money, consumption and range

Litres for a trip = distance × consumption ÷ 100. Cost = litres × price per litre. Per person = cost ÷ people in the car, driver included. Average consumption = litres ÷ kilometres × 100. Range = litres in the tank ÷ consumption × 100.

One way, fuel at 60 ₽ a litre. Worked out with this calculator.

What this calculator shows

Litres and cost for the whole journey, return leg included
The share per person in the car
Cost per kilometre and per hundred kilometres
Average consumption per 100 km and kilometres per litre from a fill-up
How far the fuel left in the tank will go

What to keep in mind

Consumption is taken as constant for the whole trip; real figures depend on road, speed, weather and load, so use your own from the trip computer or your fill-ups.
Only fuel is counted: tolls, parking, wear and servicing are not included.

FAQs

How do I work out fuel for a trip?

Multiply the distance by the consumption and divide by 100: 500 km × 8 l/100 km ÷ 100 = 40 litres. Multiply by the price per litre for the cost.

How do I find my average fuel consumption?

Fill the tank, drive, then fill it again. Divide the litres added by the kilometres driven and multiply by 100: 45 l ÷ 520 km × 100 = 8.65 l/100 km. Choose "Average consumption".

How far will the fuel in my tank go?

Divide the litres by the consumption and multiply by 100: 20 litres at 8 l/100 km is about 250 km. The "How far the tank will go" mode does it for you.

How do I split fuel costs with passengers?

Divide the fuel cost by everyone in the car, driver included. The "Per person" line shows exactly that.

How much fuel does 1,000 km take?

At 8 l/100 km, 80 litres — 4,800 at 60 per litre. On a 700 km trip for four, a car using 6 l/100 km spends 2,520 on fuel and one using 11 l/100 km spends 4,620.

What does a kilometre cost in fuel?

Consumption per 100 km times the price per litre, divided by 100: at 8 l/100 km and 60 per litre, 4.80 per kilometre and 480 per hundred.

Worked example

A 700 km drive with four people

Input: 700 km, 8 l/100 km, fuel at 60 ₽, four people including the driver

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

Note: There and back is 112 litres and 6,720 ₽, so 1,680 ₽ each. Each kilometre costs 4.80 ₽ in fuel.
