Electric cars
What would an electric car really cost you?
This compares what your petrol or diesel car costs to fuel with what a full electric car or a plug-in hybrid would cost to charge — including charging losses, cheap overnight tariffs, workplace charging, public charging and the value of the solar you could otherwise export.

What are you comparing?
Annual driving
That's about
154 miles a week
8,000 miles is our starting assumption, not a national average.
Your current fuel car
- Fuel used
- 1,039 litres
- Annual fuel cost
- £1,507
- Monthly
- £126
- Pence per mile
- 18.83p
Every 10p/litre change in the pump price changes your annual fuel cost by about £104.
The electric car
- Energy into the battery
- 2,500 kWh
- Electricity from chargers
- 2,778 kWh
- Lost while charging
- 278 kWh
Where will you charge?
Set the shares you control. Whatever is left is charged at home on your normal rate.
The mix used in this calculation
- Home normal 100%
Home — normal rate: 100% — the remaining share you requested. The shares you control add up to 0%.
Solar charging is switched off because there's no solar estimate with surplus export yet. Build a solar estimate and it will appear here.
Charging prices
Charging from solar may reduce the export income you would otherwise receive. We use your export rate as its financial cost. Solar availability is an annual planning estimate and assumes the car is plugged in when the surplus happens.
Charging breakdown
| Source | Share | Electricity | Price | Annual cost |
|---|---|---|---|---|
| Home — normal rate | 100% | 2,778 kWh | 26.11p | £725 |
No solar charging is selected, so every unit above is electricity you buy.
Effect on your home
Is this vehicle's home charging already included in your My Energy annual figure?
Your home currently uses 3,400 kWh a year. This vehicle would add about 2,778 kWh of charging at home, taking the combined figure to about 6,178 kWh a year.
- Charged at home
- 2,778 kWh
- Bought from the grid at home
- 2,778 kWh
- Solar redirected from export
- 0 kWh
Workplace and public charging are never added to your household electricity. We don't change your My Energy or Battery figures from this page.

The EV is approximately £781 a year cheaper to power.
Your weighted average charging price is 26.11p per kWh.
Every 1p/kWh change in that average changes your annual EV cost by about £28.
At your fuel economy and fuel price, the EV matches the fuel cost of your current car at an average charging price of about 54.2p per kWh — you're currently 28.1p below it.
About 278 kWh a year is lost while charging — you pay for it, but it never reaches the battery.
Charging everything on your normal rate versus everything on the cheap rate is a difference of about £531 a year.
