The formula is straightforward: Cost = (distance ÷ 100) × consumption × price per litre. For example, a 250 km trip in a car consuming 7.5 L/100km at €1.85/L costs €34.69. This calculator applies that formula in real time and also factors in additional costs such as tolls, parking fees, and depreciation.
For accuracy, it is important to use your vehicle's real-world fuel consumption — manufacturer WLTP figures are typically 10–20% lower than actual consumption in mixed driving. Measure your true consumption by noting the odometer at a full tank and dividing litres consumed by distance driven before the next fill-up.
Monthly Costs
The average household with one car drives approximately 1,200–1,800 km per month. At 1,500 km/month, 7 L/100km, and €1.85/L, the monthly fuel bill is around{' '} €194 — exceeding €2,330 per year. Two-car households effectively double that figure.
Drivers covering longer distances — sales reps, commuters, or long-haul travellers — can easily exceed €3,000–€5,000 annually on fuel alone. For trucks consuming 25–35 L/100km over 10,000 km/month, monthly costs can reach €4,600–€6,500.
Comparison
Using average European prices, the cost per 100 km is: Petrol (A95) — 7 L × €1.85 = €12.95; Diesel — 5.5 L × €1.75 = €9.63;{' '} LPG — 9.5 L × €0.85 = €8.08;{' '} Electric — 18 kWh × €0.22 = €3.96.
LPG offers genuine savings of 35–40% over petrol but requires an aftermarket installation costing €500–€1,500 and reduces boot space. Electric vehicles have the lowest per-km cost, but the higher purchase price must be factored into total cost of ownership.

Practical Tips
Tyre pressure
Keep tyres inflated to the recommended level — being 0.3 bar low increases consumption by approximately 2%.
Smooth driving
Avoid harsh acceleration and heavy braking — this alone can cut consumption by up to 15%.
Cruise control
On motorways, maintaining a steady speed saves 5–10% over manual throttle adjustments.
Air conditioning
Below 50 km/h, open windows are more efficient — A/C adds 0.5–1.5 L/100km.
Reduce weight and drag
Remove roof boxes and bike racks when not in use — they add 3–7% to consumption.
Regular servicing
A clogged air filter or worn spark plugs can increase fuel consumption by 5–10%.
Trip cost = (distance ÷ 100) × consumption × price per litre. For example, a 200 km trip with 7 L/100km consumption at €1.80/L costs €25.20.
L/100km measures how many litres are needed per 100 kilometres — lower is better. MPG (miles per gallon) measures how far you travel on one gallon — higher is better. The conversion formula is: MPG = 282.48 ÷ (L/100km).
With average petrol consumption of 7 L/100km and a price of €1.80/L: 1000 km × 0.07 × €1.80 = €126. Diesel at 5.5 L/100km costs €99. Electric at 18 kWh/100km at €0.20/kWh costs €36.
LPG typically costs 40–50% less per litre than petrol, but LPG engines consume about 25–30% more fuel by volume. The net saving is usually 20–35% depending on your vehicle and local prices.
Annual cost = monthly km × 12 × (consumption ÷ 100) × price. The monthly fuel cost field shows this automatically. For example, driving 1500 km/month at 7 L/100km with €1.80/L fuel costs €1,890/year.
Extra costs can include: motorway tolls (vignettes), parking fees, bridge and tunnel charges, and vehicle depreciation. For example, a drive to Vienna might add ~€15 for an Austrian vignette. The calculator adds these on top of the fuel cost to give you the total trip price.
Enter the vehicle's real-world consumption — typically 25–35 L/100km for heavy trucks, 12–18 L/100km for vans. Set the distance and diesel price. For a transport company's monthly costs, use the monthly distance field — for example, 10,000 km/month at 30 L/100km and €1.75/L gives €5,250 in fuel alone.
