The true cost of an electric car
The purchase price is one input. Charging setup, real-world range, depreciation and insurance decide what an electric car really costs to own. This is educational, not financial advice.
What the sticker leaves out
A wall box plus fitting is a one-off cost on top of the car, and it varies with your wiring, distance from the fuse board and any groundwork — grants where available offset only part of it.
Charging at home is usually cheapest; public rapid chargers typically cost several times more per unit, so a driver without home charging faces a very different running cost.
Real-world range falls in cold weather as heating and battery chemistry take their toll, so the usable range is often below the headline figure when you need it most.
As with any car, the value lost over time is typically the largest cost — and it can be uncertain for newer models, so it is worth checking rather than assuming.
Electric cars can cost more to insure than an equivalent petrol model, reflecting repair and battery-replacement considerations — easy to underestimate before you get a quote.
The extra weight and instant torque tend to wear tyres faster, so tyre replacement is a more frequent consumable than many buyers expect.
Why the price tag misleads
An electric car’s sticker says nothing about how you will charge it, how far it will really go in winter, or what it will be worth in a few years. A driver with cheap home charging and low depreciation can own one very cheaply; a driver relying on public rapid chargers, facing higher insurance and faster tyre wear, can pay far more per mile than the headline efficiency suggests. Whole-life cost is the only fair way to compare — the sticker hides all of it.
How to work out your true cost
Add the car’s price, then a home charger installation if you need one, your realistic charging mix (cheap home units versus the public rapid-charging premium) across your mileage, insurance, tyres and servicing, and subtract a realistic resale value for the year you plan to sell. Treat winter range as below the headline when budgeting. Compare specific cars in the calculator for a sourced, dated figure rather than a rule of thumb.

Frequently asked
It depends heavily on how you charge. Charging at home off-peak is usually much cheaper per mile than petrol; relying on public rapid chargers narrows or erases that gap. Your charging mix, insurance and depreciation decide the real answer, so work out your own whole-life total.
It is a one-off cost on top of the car that varies with your home’s wiring, the distance to the fuse board and any groundwork needed. Grants where available cover only part of it, so treat it as a real line in the total rather than free.
Yes — real-world range typically drops in cold weather because cabin heating draws on the battery and low temperatures reduce its efficiency. Budget for usable range below the headline figure when you plan longer winter journeys.
