How to calculate fuel consumption and cost
You can calculate fuel consumption for a trip from the distance travelled and the vehicle's average consumption, quoted in litres per 100 km. You get the price by multiplying the litres by the price per litre.
litres = distance (km) ÷ 100 × consumption (l/100 km) • cost = litres × price/l
Example: over 100 km at a consumption of 6.5 l/100 km you use 6.5 litres. At a price of 37,90 CZK/l that's roughly 246 CZK for the trip.
Note: the calculation is approximate. The pre-filled prices are average market values; the actual price at the pump varies by region and brand.
