The price of charging an electric car varies widely depending on where it is plugged in: from 1.50 euro at home during off-peak hours up to 14 euros on a motorway fast charger, for the same 100 km trip. This gap, often overlooked by prospective buyers, comes down to both the price per kilowatt-hour and the charging speed offered at each type of charging point. This guide breaks down 2026 rates by charging type and compares the real cost of an electric car with that of a petrol vehicle.

How much does it cost to charge an electric car in 2026

The cost of a charge depends on three main variables: the price per kWh at the charging point, the vehicle’s consumption, and the time of day the charging takes place. For an electric car averaging 17 kWh per 100 km, the bill ranges broadly between 1.50 and 14 euros depending on whether charging happens at home, on the street, or at a motorway fast charger.

This wide range explains why two drivers of the same model can end up with very different energy budgets by year end. A driver who charges exclusively at home overnight will typically pay three to four times less than one relying on public chargers during the day. The choice of electricity contract and the off-peak/peak option play a decisive role in this gap, much like the choice between petrol or diesel affects the fuel budget of a combustion vehicle.

Home charging price: off-peak and peak hours

Home charging remains the most economical option for the vast majority of electric car owners. On an off-peak plan, the kWh rate typically sits between 0.15 and 0.18 euro, bringing the cost per 100 km down to 1.50-3 euros. On a flat rate, with no off-peak/peak distinction, the bill rises slightly to 3.50-4.50 euros for the same distance.

Flat rate (no distinction)0.20 to 0.25 euro3.50 to 4.50 euros

Installing a home charging point is an upfront investment but speeds up charging compared with a simple reinforced socket. Over five years, the bill gap between off-peak and flat rate can add up to several hundred euros for a driver covering 15,000 km per year, a calculation worth factoring in when choosing between an accessible or premium best electric car.

Public and fast charger rates

Away from home, rates rise noticeably. On standard public AC chargers, installed on streets or supermarket car parks, the cost sits between 4 and 7 euros per 100 km. Fast or ultra-fast DC chargers, found on motorway service areas and certain dedicated stations, typically charge between 7 and 14 euros for the same distance.

This price difference reflects the operating cost of the infrastructure: a fast charger capable of delivering 150 to 350 kW draws on far more electrical power than a home socket, which justifies a higher kWh rate for the operator. For a driver of a premium electric car like the electric CLA tested in Paris, fast charging remains mainly relevant on long trips, with daily charging still preferable at home or at work.

Cost of motorway charging

On motorway service areas, fast charging rates generally sit between 0.45 and 0.65 euro per kWh depending on the operator and subscription type. For a 60 kWh battery charged from 20% to 80% of capacity, roughly 36 kWh, the bill reaches 15 to 20 euros versus 5 to 7 euros for the same charge done at home during off-peak hours.

Subscriptions offered by some operators and manufacturers can cut this rate by 10 to 20% in exchange for a monthly fee, a worthwhile trade-off for high-mileage drivers who regularly cover long distances. Conversely, an urban driver who only occasionally charges on the motorway generally has little incentive to subscribe.

Charging time also affects the real cost of a trip, beyond the price per kWh alone. A charger capable of delivering 150 kW recovers around 250 km of range in 20 minutes, versus more than an hour on a charger limited to 50 kW. On a long trip, choosing a higher-power station reduces downtime even if the kWh rate there tends to be a little higher than on a slower charger.

Charging price for an electric Mercedes

Mercedes-Benz’s electric range, from the CLA to the EQE, shows average consumption between 16 and 20 kWh per 100 km depending on the model and driving style. On this basis, a premium saloon charged mostly at home during off-peak hours costs around 2.50 to 3.50 euros per 100 km, an energy budget comparable to a mainstream electric model despite a larger size and superior comfort.

To compare models and available acquisition terms in the Paris region, the Mercedes-Benz electric range can be checked directly with the dealer network, which also details financing solutions tailored to each usage profile.

Electric or petrol: comparing the cost per kilometre

Energy cost remains one of the main arguments in favour of electric. For 100 km, an average petrol saloon consumes 6 to 7 litres, a bill of 9 to 13 euros at 2026 fuel prices. An electric car charged mostly at home brings this cost down to 1.50-4.50 euros, an energy budget cut by three to four times.

This advantage shrinks significantly for a driver relying exclusively on fast public chargers, where the cost per 100 km can approach that of an economical petrol vehicle. The fuel budget should therefore be compared based on actual charging habits, not just the price displayed at the pump or per kWh. This question also feeds into the choice between a best hybrid car and full electric for drivers without access to daily charging at home.

Routine maintenance widens this gap over time. An electric car has no oil changes or timing belt to worry about, two items that regularly weigh on a combustion vehicle’s budget, as detailed in the guide on when to change a timing belt. Over five years and an average mileage of 15,000 km per year, adding up the energy and maintenance line items generally confirms the economic advantage of electric, provided home charging remains the main habit.

Frequently asked questions

What is the average cost of charging an electric car?

The average cost ranges between 1.50 and 14 euros per 100 km depending on where the charging takes place. At home during off-peak hours, the lower end applies, with rates around 0.15 to 0.18 euro per kWh. On fast public chargers, the rate climbs to 0.45-0.60 euro per kWh, which explains the gap with home charging.

What is the rate for charging an electric car on the motorway?

On motorway fast and ultra-fast chargers, rates generally sit between 0.45 and 0.65 euro per kWh depending on the operator and subscription. For a 60 kWh battery charged from 20% to 80%, the bill comes to around 15 to 20 euros, versus 5 to 7 euros for the same charge done at home during off-peak hours.

How much does 100 km cost in an electric car?

For an average consumption of 17 kWh per 100 km, the cost ranges from 1.50 to 3 euros at home during off-peak hours, 4 to 7 euros on a standard public charger, and 7 to 14 euros on a fast charger. By comparison, an equivalent petrol saloon typically costs 9 to 13 euros per 100 km at 2026 fuel prices.

Is it really worth driving an electric car?

Profitability mainly depends on where the car is usually charged. A driver who charges mostly at home during off-peak hours cuts their energy bill by three to four times compared with a petrol vehicle. Conversely, relying exclusively on fast public chargers significantly reduces the economic advantage, even though it generally remains positive compared with petrol.
