Auto Cost Compared

Electric or petrol? It comes down to two questions

Every honest answer to this question starts with "it depends". It depends on two things, both of which you already know about yourself.

The verdict, for every combination

Which powertrain most often costs least to own
You driveYou can charge at homeYou cannot charge at home
10,000 km (6,000 mi)Petrol — the purchase premium dominates when you barely use the energy savingPetrol — no cheap charging and few kilometres — the EV case has nothing to work with
20,000 km (12,000 mi)Battery-electric — the off-peak energy saving now outweighs the purchase premium in most marketsConventional hybrid — public charging erodes the EV advantage; a hybrid needs no plug at all
30,000 km (18,000 mi)Battery-electric — energy is a major line and yours is the cheap oneConventional hybrid — rapid-charging prices at this distance can approach fuel cost
60,000 km (36,000 mi)Battery-electric — the largest energy saving available to any driverDiesel — motorway efficiency without a charging dependency — but check city access rules first

Read one row. That is the answer for you, and the rest of this site is why. Total-cost studies comparing powertrains reach different winners in different markets and at different mileages — that variation is the finding, not a weakness in the research [1], and it is exactly why a single universal answer would be a lie.

Why distance decides it

An electric car costs more to buy and less to run. Every kilometre you drive works off a little of that premium, so the further you drive, the better the EV case gets — and at low mileage there simply are not enough kilometres to repay it. That is the whole mechanism, and it is why the mileage pages exist.

Why charging access decides it

For an EV the energy line is not one price but two. Off-peak home charging is the cheapest fuel available to any driver; motorway rapid charging can approach the cost of petrol. Which of those you live on is set by whether you have somewhere to plug in overnight — see home versus public charging.

What would change the answer

  • A workplace charger puts you in the left-hand column even without a driveway.
  • A company car. Where benefit-in-kind favours zero-emission cars — the UK, Belgium, the Netherlands — the tax advantage can outweigh everything in this table. Check your country.
  • A cold climate. Winter raises EV consumption, mostly through cabin heating; a heat pump narrows it. See what winter really costs.
  • Very short trips only. A conventional hybrid is strongest in stop-start urban driving and needs no plug.
  • City access restrictions. They are tightening against diesel across Europe, and a car you cannot drive where you need to go is not cheap at any price.

What you control after buying

The energy line of any total-cost estimate is the one you control after purchase. Home charging on an off-peak tariff and motorway rapid charging can differ several-fold per kilowatt-hour, so where you charge on long journeys moves the annual number more than the badge does. Drive Charge Eat plans stops around cheaper, reliable chargers that also have somewhere to eat.

Is an electric car cheaper than petrol?
If you can charge at home and drive average distances or more, usually yes over ownership. If you cannot charge at home and drive little, usually no. Those two facts about you decide it more than the choice of car.
At what mileage does an EV start to win?
Around typical annual distances for a driver with home charging — the energy saving needs enough kilometres to work off the higher purchase price. Below that the petrol car’s lower purchase price tends to dominate.
What if I cannot charge at home?
The EV energy advantage largely goes, because you are buying at public rather than off-peak prices. A conventional hybrid is usually the better answer, and a workplace charger changes it back.
Is a plug-in hybrid a good compromise?
Only if you will genuinely plug it in. Real-world studies find many are charged far less than assumed, and an uncharged PHEV is a heavy petrol car.
