Calculators

Every one of these runs on your numbers rather than a national average — because an average can't tell you anything useful about your electricity bill.

• EV charging cost calculator

  Give it your electricity rate and roughly how far you drive, and it will show you what charging costs — right next to the gas car you would otherwise be filling up.

Still on the workbench

• Home charger sizing

  Which sort of charger actually suits your commute, and whether your electrical panel can cope with it.

• Road trip cost estimator

  What a long drive will cost you in public charging, and how many stops you are realistically looking at.
