Fuel cost calculator
The cost is the liters the trip uses times the price you type. Nothing on this page looks up a station price.
Consumption is liters per 100 kilometers, the figure printed on many car stickers. Distance is in kilometers.
Calculator
Required fields are marked with *.
Use a comma or a dot for the decimal, as in 12.5 or 12,5. Type thousands as 1000 or 1 000. A single comma or dot is the decimal mark, so 1,000 means 1.
Results

How to use this calculator
- Enter the distance in kilometers.
- Enter consumption in liters per 100 km, and the price per liter.
- Read the liters and the cost. Change the price when the pump price changes.
Formula
liters = distance / 100 × liters per 100 km
cost = liters × price per liter
Worked example
500 km at 6.5 L/100 km and 7 per liter
500 / 100 × 6.5 = 32.5 liters.
32.5 × 7 = 227.50.
32.50 liters, costing 227.50.
Questions
Why is there no live price?
Pump prices move by place and by day. A typed price stays under your control and does not go stale in a static page.
What if I know miles per gallon?
Convert to liters per 100 km first, or use the unit converter for the distance and then this page for the cost. This form does not mix gallon prices.
Does this include stops or traffic?
Only through the consumption figure you enter. A higher consumption number is how you represent a less efficient trip.
