If you want to buy an electric car, you often do not only think about the positive environmental aspect – the purchase can also pay off for your own finances. Cars that run on electricity are considered to be cheaper than petrol or diesel. This is hardly surprising given the extremely high fuel prices, but how much cheaper is an e-car really?
E-cars run cheaper: Stromer saves so much on the charging station
If you change to an electric car, you usually have to pay more than for a comparable internal combustion engine. But in the long run, the change should still be worth it. For electric cars, it is for several reasons the cheaper option in the long run.
This is mainly due to the cheaper charging current. Thanks to this, e-cars are especially valuable, as electric drivers can literally save themselves the extreme prices at the pump for petrol and diesel. They have recently climbed to record levels again, and the effect of the tank discount is virtually impossible to detect.

According to ADAC expert Florian Hördegen, when it comes to saving, where you charge your electricity to the electric car. Public charging stations, for example in the city, are significantly more expensive than charging at home at the household electricity tariff. You can save a lot of money if you also use a photovoltaic system and can thus reduce the price per kWh.
The comparison shows how big the differences can be: A diesel from BMW with a consumption of 5 l per 100 km reached the price peak in March 2022 EUR 2.35 per liter on pure fuel costs of EUR 11.75 for the track. The comparison of SAT.1 Bayern contrasts with the outgoing model BMW i3. The electric car consumes about 15 kWh during 100 km.
By comparison, owners of a photovoltaic system assume a price of 11 cents per kWh – unbeatably cheap. So charged they cost 100 km in i3 only 1.65 euros and thus currently less than a single liter of diesel. But even without solar power, e-car drivers will be much cheaper: With 35 cents per kWh in household electricity prices, 100 km with an e-car would come to 5.25 euros – still less than half the fuel cost of an internal combustion engine.
At Electricity prices are highest at public charging stations. In this case, it costs 7.35 euros for electricity to drive over 100 km in i3. The comparison of Verivox comes at similar costs.
In addition to charging current: E-cars have other price advantages
But e-cars are not as cheap to maintain as they have been so far. Not only are fuel prices rising at the moment, energy is becoming much more expensive overall. This also applies to e-cars, in direct comparison they have in terms of charging cost compared to petrol and diesel, they are still much better short. In addition, other price advantages, such as fewer wearing parts and the quota for greenhouse gases, benefit e-car drivers.
