How Much Does It Cost to Charge an EV at Home? (2026 Guide)

A full home charge typically costs $8-15 in the US and more in Europe. Here's the simple math, with worked examples for the US, UK, and EU.

EVChargingCost Comparison

The short answer

Charging at home is almost always the cheapest way to run an EV. As of mid-2026, a full charge of a typical 60-75 kWh battery costs roughly:

  • US: $10-14 at the average residential rate of about $0.17-0.18/kWh
  • UK: £17-22 at a standard tariff around 27-29p/kWh, or as little as £5-7 on an EV overnight tariff
  • EU: €17-23 at an average household rate around €0.28-0.30/kWh

Those are full-battery numbers, and you rarely charge from empty. Day to day, you're topping up whatever you drove. That's the number that matters.

The math (it's genuinely simple)

Two formulas cover everything:

  • Cost of a charge = kWh added × your price per kWh
  • Cost per distance = consumption per 100 km (or miles) × your price per kWh

Say your car uses 18 kWh/100 km and you pay €0.29/kWh. That's €5.22 per 100 km. A petrol car using 7 L/100 km at €1.80/L costs €12.60 for the same distance. The fuel cost calculator does this comparison for you with your own numbers.

Don't forget charging losses

Not every kWh you pay for ends up in the battery. Between the onboard charger, cables, and battery management, expect to lose around 5-15%. On a regular wall socket it can be worse than that.

So if your car gained 50 kWh, you probably paid for 53-57 kWh at the meter. It's not a dealbreaker, but if you're trying to be accurate, add it in. There's a whole guide on charging losses if you want the details.

Your tariff matters more than your car

Here's what most people miss: the spread between electricity tariffs is bigger than the efficiency spread between EVs.

  • Standard flat rate: fine, but you're leaving money on the table
  • Time-of-use tariff: off-peak overnight rates are often 30-60% cheaper
  • Dedicated EV tariff: some providers offer overnight rates that undercut even standard off-peak pricing

An efficient EV on an expensive flat tariff can cost more per km than a thirstier EV on a good overnight rate. Before optimizing your driving style, optimize your tariff.

What about solar?

If you have solar panels and charge during the day, your marginal cost can approach zero, minus what you'd have earned exporting that power. The honest way to count it is to use your export rate (what the grid would have paid you) as your charging price, not zero.

Worked example: a year of home charging

Take a fairly typical setup: 15,000 km per year, 18 kWh/100 km, 10% charging losses.

  • Energy needed: 15,000 / 100 × 18 × 1.10 = about 2,970 kWh from the wall
  • At €0.29/kWh: about €860 per year
  • At an overnight EV rate of €0.15/kWh: about €445 per year

The same distance in a 7 L/100 km petrol car at €1.80/L runs about €1,890 per year. Even on the expensive tariff, the EV saves over €1,000 a year on energy alone.

Run your own numbers

Averages are a starting point, not an answer. Your rate, your consumption, and your driving distance can move these results a lot in either direction. Plug your actual numbers into the calculator and see where you land. And if you're weighing up a purchase, the ownership calculator covers the full picture beyond fuel.
