Electric family car: the real cost over 5 years

Over five years and 75,000 km, the energy gap between the thriftiest and the thirstiest electric family car comes to €450. The gap between charging the same car at home or on a public charger comes to €3,450. The budget of an electric family car is therefore settled at the socket, not on the spec sheet.

What does an electric family car really cost over five years?

Between €3,700 and €4,200 in energy if you charge at home on an off-peak tariff. Between €7,000 and €7,900 if you depend on public chargers. Same car, same family, same mileage: only the socket changes, and it moves close to €3,500 over five years.

Total cost of ownership, or TCO, is the sum of everything the car takes from you while you keep it: purchase minus resale value, energy, servicing, taxes, insurance, tyres. It is the only figure that matters to a family, and it is the one no brochure ever prints.

Take Amélie and Rachid, 37 and 40, two children aged 6 and 9, a third-floor flat in Schaerbeek, no garage, a space in the street when they are lucky. They cover 15,000 km a year, so 75,000 km over five years: the school run, the shopping, the in-laws in Namur, two weeks in the Var in August. Their 2016 diesel is reaching the end of the road and they are looking at electric. On paper, every article promises them savings. In their specific case, those articles are wrong, and here is why.

Why does the charging point weigh more than the model?

Because the price of a kWh doubles between a garage and a street, while consumption varies by only 12% between two electric family cars. A model's efficiency is a marginal criterion; access to a private socket is a structural one.

The Belgian figures leave no room for doubt. At home on a dual-rate contract, the night kWh sits around €0.30. On public chargers, Moniteur Automobile recorded an average of €0.52/kWh on alternating current and €0.67/kWh on direct current in June 2025, ranking Belgium fifth in Europe for the most expensive charging, at roughly €8.40 per 100 km, behind Norway, Slovenia, Italy and Germany. Touring goes further: above 100 kW you pay at least €0.69/kWh, sometimes close to a euro.

The order of priorities therefore flips. A family spends three weeks comparing WLTP consumption figures to a tenth of a kWh, for €450 at stake over five years, then ticks "no home charger" in thirty seconds, for €3,450 at stake. Test-Achats does quote €4.50 to €8 per 100 km for electric against roughly €13 for combustion, using March 2026 figures: that €4.50-to-€8 range is not a margin of error, it is the distance between two sockets.

What do 100 km actually cost in an EV in Belgium?

From €5.19 to €11.59 for the same family car. Take a Renault Scenic E-Tech 87 kWh, measured at around 17.3 kWh/100 km in real use. At home on an off-peak tariff at €0.30/kWh, 100 km cost €5.19. On a public AC charger at €0.52, they rise to €9.00. On a rapid charger at €0.67, they hit €11.59, less than two euros away from a tank of petrol over the same distance. The car has not changed its nature between Monday and Tuesday: the socket has changed its price.

What happens to the sums when you live in a flat?

They collapse almost entirely. A Peugeot e-5008 charged exclusively on rapid chargers uses 13,875 kWh over 75,000 km, so €9,296 of energy over five years. An equivalent petrol family car at 7 L/100 km, at July 2026 prices, costs €9,712. The gap falls to €416 over five years, or €83 a year.

Eighty-three euros a year. For that, Amélie and Rachid are asked to accept a purchase premium of several thousand euros, faster depreciation, and the uncertainty of finding a free charger on a Sunday evening. The sum does not work, and it does not work because of a figure that appears on no spec sheet: their postcode and the absence of a garage.

The case is anything but marginal. Serena Galeone, spokesperson for Sibelga (the Brussels distribution network operator), put it to the RTBF in February 2025: "Brussels is an urban environment, so it is complicated for every user to have their own charger." The Region has launched the electrify.brussels and charge.brussels platforms to map available chargers, and Sibelga is working on a rotation tariff, because drivers stay on a charger on average three times longer than needed. A rotation tariff is one more line on Amélie and Rachid's bill, not on that of a garage owner in Gembloux.

Is there a middle way without a garage?

Three, and none is perfect. Charging at work, if the employer offers it, solves the problem completely, but it depends on a third party. Operator subscriptions bring DC down to around €0.40-0.50/kWh, at the price of a restricted charger network: the card does not work everywhere, and it is usually when it does not work that you pay the full rate. Free charging at some supermarkets exists, but it is neither guaranteed to last nor within reach of everyone. None of these three replaces a socket of your own; they soften the blow, they do not reverse it.

Which electric family car is cheapest to run?

The Kia EV3, though the gap is too small to settle a purchase. Here are the figures, over five years and 75,000 km, with consumption measured in real use and indicative Belgian market prices in July 2026, excluding options. The "home" column applies €0.30/kWh off-peak, the "public charger" column a realistic mix of 70% AC at €0.52 and 30% DC at €0.67.

Read the table left to right, then top to bottom. Vertically, from the Kia to the Peugeot, energy varies by €450 over five years, while boot space climbs from 460 to 748 litres and the e-5008 adds two seats. Horizontally, on any given row, moving from the "home" column to the "chargers" column costs between €3,279 and €3,677. A family of five choosing the Kia over the Peugeot to save €450 of electricity would be making a very poor deal, and our comparison of electric family MPVs explains why seats always beat kWh.

What grants and taxes are left in Belgium?

Almost nothing on grants, and little on taxes. None of the three Regions still pays a private buyer a purchase grant in 2026: the Flemish scheme, the last one standing, closed at the end of 2024. Some municipalities keep a local subsidy, worth checking one by one.

The remaining tax advantages are real but modest. Registration tax comes to a flat €61.50 in Flanders, starts at €50 in Wallonia under a formula crossing power, mass and emissions, and drops to the €75.79 minimum in Brussels. Annual road tax is capped at €102.96 for a zero-emission vehicle in both Wallonia and Brussels, against €186.25 for an equivalent petrol. Over five years, the road-tax gap comes to roughly €415: real, but eight times smaller than the socket gap.

One word about the sources in this market. The best-documented consumer article on the cost of electric cars in Belgium is published by Engie, an energy supplier, and its conclusion is that home charging is the cheapest solution. That is accurate. It is also commercially convenient. The question "is home charging cheaper" has a simple answer: yes. The question "what do you do if you have no access to it" interests no energy supplier, and it is precisely the one Amélie and Rachid are asking.

Why is public charging still so expensive in Belgium?

Because most EV drivers do not pay for their own charging. Moniteur Automobile spells it out: charging costs for company cars are usually covered by the employer, which reduces the pressure on tariffs. The figures back the diagnosis: in 2025, only 18% of new electrified cars registered in Belgium went to private buyers, according to data reported by Engie and Febiac (the Belgian automotive federation). Statbel counted 14% private buyers in 2024.

Translated for Amélie and Rachid: they are buying a car in a market built for fleets, and they pay a price at the charger that 82% of users never look at. Competition between operators stays limited, taxation on electricity is heavy, and nothing pushes the system down. A family charging in the street is effectively subsidising a market that was not designed for them.

Should you install a home charger before buying?

Yes, and in that order. Charger first, car second. A wall box costs between €500 and €2,750 excluding VAT according to Test-Achats, plus installation by a certified electrician (sometimes dearer than the box itself) and, in older houses, an upgrade to the consumer unit.

Against €3,450 of energy savings over five years, the investment pays for itself in almost every scenario. The trap is not financial, it is chronological: signing the order for an EV while telling yourself you will sort out the charger later, then discovering that the building's management refuses, that the meter cannot cope, or that the connection takes six months. What we would avoid: ordering the car before holding a signed charger quote and written approval from the building's management.

Does the tax reduction for a home charger still exist?

No. The federal tax reduction granted to private individuals installing a home charging point has ended, as the RTBF reported in July 2024. It is a useful illustration of how this file moves: between 2021 and 2026, Belgian private buyers watched both the Flemish purchase grant and the charger tax deduction disappear, while the company-car regime stayed attractive. The movement runs in one direction, and it is not the families' direction.

Before comparing a single model, do one thing: look at where you are going to plug in. A garage space, a driveway, a shared car park with an accessible meter: that is the line that decides €3,450. The rest can be compared in our family car comparator and in our file on the real range of an electric family car.
