What does a kilometre cost: electric or petrol?

Short answer: a kilometre of home charging, for a typical new car, costs a few cents. Public charging costs more. Petrol, at the pump price of 5 October 2026, costs €17.85 per 100 km. ERE on home charging sits beside that, as income, not as a discount at the pump. Tax, depreciation and maintenance are in none of these amounts. The full bill, with your model and your kilometres, is on the EV cost scan.

What does a kilometre of home charging cost?

Consumption comes from the EEA figures for new cars in the Netherlands, field Z: electric energy from the grid, in Wh per km. The file was retrieved on 27 September 2026. 2024 is final, 2025 is provisional. Versions are grouped into 62 model families. The typical car in this article is the median, weighted by registrations in 2024 and 2025 together: 157 Wh per km, so 15.7 kWh per 100 km. Over 15,000 km that is 2,355 kWh. WLTP is a laboratory value. On the road, in winter or on the motorway, use is often higher. Nothing here corrects for that.

The home electricity price is the same one as in the cost scan. From October 2025 through September 2026 the daily average on a dynamic contract is €0.2585 per kWh. Smart charging, the average of the four cheapest hours of each day, is €0.1859 per kWh. Both include the exchange price (Energy-Charts, SMARD data), energy tax from the Belastingdienst, VAT, and the median markup of the dynamic contracts that publish one. Standing charges and grid costs are left out. You pay those even when the car is parked.

Per 100 km that is €4.06 for the daily average and €2.92 for smart charging. The same number in cents is the price per kilometre: 4.06 cents and 2.92 cents. A fixed or variable contract has no hourly price. Those two amounts apply only to a dynamic contract. How the contracts differ is on dynamic energy contract.

The cost scan also uses a practice figure: 18.7 kWh per 100 km, the EV Database average, checked on 27 September 2026. At the home price that is €4.83 per 100 km. Higher than the WLTP median, because 18.7 kWh per 100 km is 187 Wh per km.

What do public charging and petrol cost per kilometre?

Public charging in this table is the ad hoc rate: charging without a card, the rate the network itself publishes. On 21 October 2026 the median of 3 networks with an AC rate is €0.57 per kWh, and the median of 4 networks with a DC rate is €0.805 per kWh. The ends of the ranges we have run from €0.36 to €0.62 for AC and from €0.54 to €0.86 for DC. A charging card can add a start fee, a subscription or a different kWh price. The cards are on charging cards and the networks on charging prices. The article what public charging costs sets the rates side by side.

At 157 Wh per km that is €8.95 per 100 km on AC and €12.64 on DC. In cents per kilometre: 8.95 and 12.64.

Petrol uses two sources that do not measure the same moment. Consumption is 7.34 litres of E10 per 100 km for a medium car, segment C. That is practice use from TNO data for 2021, published by Milieu Centraal in the 2022 CO2 emission factors for passenger transport. We do not have a newer official litres-per-100-km figure. The pump price is current. CBS StatLine 80416NED gives a weighted average daily price, including VAT and excise, and the figures are final as published. On 5 October 2026, the latest day in the table when we read it on 13 October 2026 (the table was updated on 8 October 2026), Euro95 cost €2.432 a litre.

7.34 litres times €2.432 is €17.85088 per 100 km, rounded to €17.85. That is 17.85 cents per kilometre. It is not a like-for-like comparison: the electric side is a laboratory value from 2024 and 2025, the petrol side is 2021 practice at an October 2026 pump price.

What does ERE earn per kilometre?

ERE is a payment for home charging, not a discount on the kWh price. In 2026 each kWh charged earns 0.33269 ERE (NEa, 2 February 2026). The euros follow the ERE price. On 18 October 2026 that price is €0.460, gross €0.153 per kWh. After the median commission of 20% this calculation keeps €1.92 per 100 km, if every kilometre was charged at home. Over 15,000 km that is €288.33 a year. Public kWh do not count here. A charge point without a built-in MID meter does not either. How booking works is in what the ERE payment for home charging is.

The energy contract does not change that amount per kWh, except where a supplier ties its own deal to the contract. Which contract that is, is in which energy contract you choose for 2027.

What does 15,000 kilometres a year cost?

15,000 km is the distance the cost scan uses by default. At 157 Wh per km and the prices above:

	Per 100 km	Per year, 15,000 km
At home, smart charging (dynamic)	€2.92	€437.81
At home, daily average (dynamic)	€4.06	€608.77
Public, AC, median	€8.95	€1,342.35
Public, DC, median	€12.64	€1,895.77
Petrol Euro95, 7.34 litres, €2.432	€17.85	€2,677.63
ERE, net, all charged at home	€1.92	€288.33

The petrol row is 150 times €17.85088, rounded to the cent: €2,677.63. The ERE row is income, not a cost. It belongs only with the home rows, and only if every kWh at home passed a MID meter. If you mix in public charging, ERE counts only on the home share.

At the practice use of 18.7 kWh per 100 km, home charging on the daily average is €725.09 a year, and net ERE is €343.42. On the cost scan you pick a model from the list, or your own consumption, and a different distance. The models are also on electric cars.

What is not in these amounts?

Energy per kilometre only. Left out:

• Purchase and depreciation. The purchase price, the residual value and the gap between them. A way in is buying an electric car.
• Tax. BPM, road tax and company-car addition. What the 2027 law says is in tax on an electric car.
• Maintenance, tyres and insurance. None of these sources gives one amount per kilometre that fits every car.
• Fixed energy costs. The supplier’s standing charge, the grid operator’s costs and the energy-tax reduction. Those sit on the connection, not on the kilometre.
• A charging card. A start fee and a subscription on public charging. The kWh price in the table is the rate without a card.

The cost scan counts the energy and the ERE for your kilometres. It does not count these fixed items either. Set them beside the cents per kilometre in this table when you compare a car.
