Fuel Cost Calculator in Kilometres
For trips measured in kilometres, with the vehicle rated in litres per 100 km or kilometres per litre and fuel priced by the litre. The page opens on 500 km at 7 L/100km and 1.80 a litre: 35 litres and 63.00. Switch to km/L for a vehicle quoted the other way round.

Enter the price in whatever currency you buy fuel in. The answer comes back in the same one, because the arithmetic never touches an exchange rate.
Two gallons, and one unit that runs backwards. Choose the gallon used by your fuel price and efficiency figure. L/100km measures fuel per distance, so a lower number means less fuel used, and it multiplies where mpg divides. Every conversion the answer needs is written into the working above with the constant it used, so you can check which gallon went where.
Common questions
- How do I calculate fuel cost per km?
- Multiply the L/100km by the price per litre and divide by 100. At 7 L/100km and 1.80 a litre that is 0.126 a km, so 500 km costs 63.00. The Per mile and per km row shows it for your own numbers.
- How do I convert km/L to L/100km?
- Divide 100 by it: 14 km/L is 7.14 L/100km. The calculator takes either unit, so there is no need to convert first.
- Does it work in rupees, euros or dollars?
- Yes. Enter the price per litre in your own currency, such as 102.50 rupees or 1.80 euros, and the total comes back in the same currency. No exchange rate is involved.
Exact arithmetic on the numbers entered: distance divided by efficiency, times price. Real consumption varies with speed, load and weather, so treat the result as the figure your own inputs imply.
