EV vs petrol or diesel, in your situation.
How much you actually save (or don't) switching to an EV depends almost entirely on your mileage and your charging mix. Edit the numbers, see the maths update. Every assumption is visible.

The maths
| EV | Your current car | |
|---|---|---|
| Fuel burnt | 2222 kWh | 808 L |
| Annual cost | £317 | £1172 |
| Pence per mile | 4.0p | 14.6p |
Assumptions worth knowing
- Fuel cost uses pump-price per litre and the UK gallon (4.546 L).
- EV cost uses a blended tariff: home share × home tariff plus public share × public tariff. Off-peak overnight (Intelligent Go, Agile) is where home EV charging actually wins.
- Real-world EV efficiency varies with temperature, speed and load. 3.6 mi/kWh is a typical UK family-EV mixed-driving figure; aggressive motorway driving in winter can drop to 2.8 mi/kWh.
- Excludes road tax, insurance, servicing, tyres, depreciation. Those are modelled in the full buyer report.
The full picture
Running cost is one of seven sections in the buyer report. The others cover real shortlists, listings, salary sacrifice maths, and the buying checks every used buyer should run.
