Last month, a colleague texted me: "Christophe, I want to go electric, but concretely — how much is it going to cost me per month?" The short answer: less than he expected. The longer answer: it depends on the model, where you charge, and which Belgian region you live in.

Here's the real monthly budget for an EV in Belgium, line by line, with June 2026 figures.

What are the 5 components of a monthly EV budget?

The monthly cost of an electric vehicle in Belgium breaks down into five recurring expense lines, excluding any loan repayment or lease payment.

Energy (charging): the most variable item. At home on the average Belgian domestic tariff (€0.25/kWh based on CREG Q2 2026 data), 15,000 km/year comes to €45-60/month depending on the model's consumption. On public chargers only, the budget triples.

Insurance: between €50 and €110/month for liability plus comprehensive cover. The price depends on the model and its list value, not the powertrain. AG, P&V and BNP Paribas Fortis offer 10 to 30% discounts for EVs in 2026.

Maintenance: €15 to €25/month. No oil changes, no timing belt, brake pads that wear half as fast thanks to regenerative braking. The first service at the dealership comes down to the cabin filter, fluid levels and electronic diagnostics — between €100 and €200.

Taxes: the annual road tax is around €90-100/year in Wallonia and Brussels (based on 4 fiscal HP), or €8/month. In Flanders, the flat rate is €61.50/year since January 2026. The registration tax (TMC/BIV) is €61.50 in all regions (full exemption in Brussels).

Vehicle inspection (contrôle technique): about €50 every two years, or €2/month. Same as a combustion car.

How much do 4 popular models cost per month in Belgium?

Monthly running costs for 15,000 km/year with home charging (€0.25/kWh):

ItemDacia SpringRenault 5 E-TechSkoda Enyaq 60Tesla Model Y
Belgian list price€16,990€24,990€37,490€44,990
Energy (home)€47€50€58€55
Insurance (liability + comprehensive)€50€67€92€108
Maintenance€15€17€23€21
Taxes + inspection€10€10€10€10
Running cost/month€122€144€183€194

Assumptions: real-world consumption of 15 kWh (Spring), 16 kWh (R5), 18.5 kWh (Enyaq), 17.5 kWh (Model Y) per 100 km. Full comprehensive insurance, quotes compared across 3 Belgian insurers. Wallonia road tax. Maintenance estimated from manufacturer data and the Touring 2025 study.

What if I don't have a home charger?

The energy budget changes completely. On public AC chargers (€0.45/kWh average, Allego/TotalEnergies network), the Renault 5's €50/month jumps to €90. On fast charging only (€0.65/kWh on Ionity or Fastned without a subscription), it climbs to €130/month.

For a Renault 5 E-Tech, the annual difference between home and public AC charging reaches €480. That's the cost of a wallbox installation recovered in just over two years. Installing a 7.4 kW charger in Belgium costs between €1,200 and €2,500 including fitting.

How does a monthly EV budget compare to diesel?

The comparison speaks for itself when you line up the items. Take two cars from the same segment: the Renault 5 E-Tech (€24,990) against a Renault Clio V diesel 1.5 dCi (€22,500), both at 15,000 km/year.

ItemRenault 5 E-TechClio V diesel
Energy€50€120
Insurance (liability + comprehensive)€67€63
Maintenance€17€33
Taxes (road tax + TMC/48)€10€32
Inspection€2€2
Running cost/month€146€250

In running costs, the Renault 5 E-Tech costs €104/month less than a Clio diesel. Over 4 years, that's €4,990 recovered — enough to cover the list price difference between the two cars.

The diesel calculation: 5.5 L/100 km × €1.75/L (Belgian diesel price, May 2026) = €0.096/km. Diesel maintenance: oil changes every 15,000 km, timing belt, particulate filter — double what an EV needs. Road tax: approximately €250/year for a diesel in Wallonia, versus €100 for the EV.

Even with the car loan (€2,500 more to finance on the R5), the total monthly budget remains lower than the Clio diesel — by around €50/month.

What's the advantage for a company car?

For the self-employed or companies, the maths tip even further in favour of the EV. The 100% deductibility is maintained for any EV ordered before 31 December 2026 (source: SPF Finances / FPS Finance). The BIK (benefit in kind, known as ATN in Belgium) is calculated using the minimum CO₂ coefficient of 0.82%. Over 48 months as a company vehicle, the Renault 5 E-Tech works out roughly 40% cheaper than a Clio diesel after tax deductions.

What monthly budget fits your driver profile?

Three Belgian driver profiles, calculated with the same assumptions (home charging, comprehensive insurance, Renault 5 E-Tech):

Profilekm/yearEnergyTotal running cost
Brussels city driver10,000€33€119
Namur–Brussels commuter22,000€73€159
Walloon family18,000€60€146

The Brussels city driver at 10,000 km/year drops below €120/month in running costs. The Namur–Brussels commuter on the E411, at 22,000 km/year, caps out at €160/month — versus approximately €325/month in diesel at that mileage.

On the E411, I measured consumption of 18 kWh/100 km at 120 km/h in March, compared with the 16 kWh Renault quotes for the combined cycle. The commuter budget uses this real-world motorway consumption.

Le verdict de Christophe F.

The real monthly cost of an EV in Belgium holds no mystery once the 5 line items are laid out. For a compact, expect €120 to €195/month in running costs with home charging. That's €100 less than an equivalent diesel, every month, before even counting company car tax benefits. The one item that can flip the calculation: public charging only, which triples the energy budget. Investing in a wallbox remains the single most cost-effective decision you can make.
