EVStats is an independent database of 1,423 electric cars, so this calculator already knows your car's usable battery and official range: pick the model, set your tariff, and see the cost. It answers what a charge costs. For how long a charge takes, use the simulator; for EV vs petrol cost over several years, the TCO calculator; and for a longer guide to what EV charging costs, read the blog.

Rapid: A typical public DC retail band, not EIA and not a network tariff
On an off-peak EV tariff, type your night rate.
Energy into the battery, from the official WLTP figures. Your meter reads a little more, because some energy is lost as heat while charging, and winter and motorway driving use more per mile: see the winter range on each car page.

Charging SimulatorLast updated 2026-10-20.
| Car | Usable battery | 10 to 80% at home | 10 to 80% at a rapid charger | Home cost per 100 miles |
|---|---|---|---|---|
| Renault 5 E-Tech 52kWh 150hp | 52 kWh | £9.58 | £28.76 | £6.57 |
| MG MG4 Premium Long Range (MY26) | 61.7 kWh | £11.37 | £34.12 | £7.26 |
| Tesla Model 3 Long Range RWD (Highland) | 75 kWh | £13.82 | £41.48 | £5.78 |
| Tesla Model Y Long Range RWD (Juniper) | 75 kWh | £13.82 | £41.48 | £6.76 |
| Nissan LEAF Extended Range 75 kWh (MY26) | 75.1 kWh | £13.84 | £41.53 | £6.92 |
| Škoda Elroq 85 (MY27) | 77 kWh | £14.19 | £42.58 | £7.25 |
| Kia EV3 Long Range (MY27) | 78 kWh | £14.37 | £43.13 | £7.26 |
| Hyundai IONIQ 5 84 kWh RWD (MY24) | 80 kWh | £14.74 | £44.24 | £7.53 |
At home on a standard tariff you pay the Ofgem price cap, 26.32p per kWh for 1 October to 31 December 2026 (GB average, direct debit).
On the public network, slow and fast chargers (3 to 49 kW) averaged 54p per kWh and rapid and ultra-rapid chargers (50 kW and above) 79p in September 2026, according to the Zapmap Price Index.
So a 10 to 80% charge of a Kia EV3 Long Range (MY27) costs £14.37 at home and £43.13 at a rapid charger. Type your night rate into the calculator: the price cap is the ceiling for a standard tariff, not what EV tariffs charge at night.
It is the usual stop on a rapid charger. Charging power is highest in the lower half of the battery and drops sharply above 80%, so the last 20% takes much longer for the same energy. More on how much to charge at a charging station. At home, the price per kWh is the same whether you stop at 80% or 100%.
The cost per mile here uses the official WLTP range. Cold weather and motorway speeds use more energy per mile, so the real cost per mile is higher. See real-world vs WLTP range in winter and EV range in cold weather.
At the Ofgem price cap for 1 October to 31 December 2026, 26.32p per kWh (GB average, direct debit), a 10 to 80% charge costs £14.37 for a Kia EV3 Long Range (MY27) with 78 kWh usable, and £9.58 for a Renault 5 E-Tech 52kWh 150hp. That is the energy that goes into the battery; on an off-peak EV tariff, use your night rate instead.
Rapid and ultra-rapid chargers (50 kW and above) averaged 79p per kWh in September 2026, according to the Zapmap Price Index. At that price a 10 to 80% charge of a Kia EV3 Long Range (MY27) costs £43.13, against £14.37 at home on the price cap.
Multiply the usable battery in kWh by the share you charge and by the price per kWh. For a Kia EV3 Long Range (MY27): 78 kWh x 70% (10 to 80%) x £0.2632 = £14.37. The calculator on this page already knows the usable battery of each car in the catalogue, so you only set the tariff.
It is on an off-peak EV tariff. The 26.32p figure is the Ofgem price cap for a standard tariff (1 October to 31 December 2026), the ceiling for that tariff, not what EV tariffs charge at night. Type your night rate into the calculator to see the cost for your car.
Public slow and fast chargers (3 to 49 kW) averaged 54p per kWh in September 2026, according to the Zapmap Price Index. A 10 to 80% charge of a Kia EV3 Long Range (MY27) at that price costs £29.48.
Divide the usable battery by the official WLTP range to get energy per mile, then multiply by your price. A Kia EV3 Long Range (MY27) uses 27.6 kWh per 100 miles on that basis, so it costs £7.26 per 100 miles (7.3p a mile) at 26.32p and £21.80 per 100 miles at 79p. Of the eight cars in the table, the Tesla Model 3 Long Range RWD (Highland) is the lowest at £5.78 per 100 miles at home. Winter and motorway driving use more per mile.
