RUNNING COSTS
How to calculate EV cost per mile
Cost per mile gives you a quick way to compare charging options and check how your EV running costs compare with petrol.
Formula
Simple equation for daily planning
Divide your electricity unit rate by your EV efficiency in miles per kWh. The result is your electricity cost per mile.
Most drivers can reduce this figure significantly by shifting charging to overnight EV tariffs.
Current UK benchmark rates are published at pricecaprates.co.uk.
Formula card
Cost per mile equation
(Electricity rate in pence) ÷ (Miles per kWh)
Example
26.11 ÷ 4.5 = 5.8p per mile
Lower rates and higher efficiency both reduce your running cost.

Efficiency figures are real-world estimates based on manufacturer specifications and owner data. Actual efficiency varies with speed, temperature, driving style, and payload. Cold weather and motorway driving reduce efficiency compared to mixed or urban driving. Fuel type costs use approximate June 2026 average pump prices.
