Calculation
K = v·Preis
Cost per 100 km is the product of consumption and price per litre, and thus directly proportional to both.
K = v·Preis (Definition; Dubbel Kraftfahrzeugtechnik Q 11.2 nur als Kontext)

Result
Select a target and calculate.
Understand the inputs
- Fuel cost K per 100 km — Cost of the fuel consumed over 100 km, in the same currency as the entered price.
- Average consumption v in l/100 km — Average fuel consumption per 100 km driven.
- Fuel price per litre — Current fuel price per litre in the desired currency.
Example
v=6.5 l/100 km and price=1.75 (currency/l) give K=6.5·1.75=11.375 (currency/100 km).
Assumptions and limits
Constant average consumption and constant fuel price over the considered distance; price fluctuation, station-dependent pricing and consumption changes from driving style or payload are excluded.
Understand Fuel cost per 100 km
This calculator determines fuel cost per 100 km driven, complementing the existing range calculator with the cost side of the same vehicle class.
What does this quantity describe?
Cost per 100 km follows directly as the product of consumption per 100 km and fuel price per litre: K=v·price.
Formula and variables
K = v·Preis
K = v·price
| Symbol / input | Meaning |
|---|---|
| Fuel cost K per 100 km | Cost of the fuel consumed over 100 km, in the same currency as the entered price. |
| Average consumption v in l/100 km | Average fuel consumption per 100 km driven. |
| Fuel price per litre | Current fuel price per litre in the desired currency. |
Choose the inputs correctly
v is average fuel consumption per 100 km, price the current fuel price per litre.
How to use the calculator
Take v from the on-board computer or your own consumption tracking, price from the current filling-station price.
Worked example
v=6.5 l/100 km and price=1.75 (currency/l) give K=6.5·1.75=11.375 (currency/100 km).
Understand the result and units
Since both inputs enter linearly, K doubles both when consumption doubles and when fuel price doubles.
v is a dimensionless consumption figure in l/100 km, price a currency per litre. K is output as a cost figure per 100 km in the same currency.
Typical applications
Comparing running fuel costs of different vehicles or driving styles, trip cost accounting, and budget planning.
Assumptions, limits and common mistakes
Constant average consumption and constant fuel price over the considered distance; price variation between filling stations, discounts, toll fees and depreciation are not accounted for.
Common mistake: Do not confuse the per-litre price with the cost per 100 km; the two differ by the consumption factor.
