Assumptions

  • Rightcar’s kWh/100km doesn’t say whether it includes charging losses, so every EV running cost adds 10%.
  • Charging “mostly at home overnight” is priced at 50% of the region’s price, the basis of retailers’ overnight EV plans.
  • Running costs are energy and road user charges only: no servicing, tyres or insurance.
  • A figure that doesn’t clear its minimum sample is left out.
