For most EV owners, home charging is the difference between "EVs are great" and "EVs are a hassle." Done right, it's cheap, effortless and always available. Done wrong, it can cost you more than public charging.
Here's exactly what home charging costs in 2026 — and how to minimize it.
The home charging cost breakdown
| Scenario | Electricity rate | Cost per 100 km | Cost per full charge (60 kWh) |
|---|---|---|---|
| Night tariff (cheap hours) | $0.08/kWh | ~$2.40 | ~$4.80 |
| Standard residential | $0.15/kWh | ~$4.50 | ~$9.00 |
| Peak-hour tariff | $0.25/kWh | ~$7.50 | ~$15.00 |
| Premium peak (some regions) | $0.40/kWh | ~$12.00 | ~$24.00 |
With a night tariff, home charging is 4–8x cheaper than public fast charging — and typically 3–4x cheaper than gas. This is the single biggest financial advantage of EV ownership.
The "cost per 100 km" math
Assuming ~3.5 mi/kWh (about 22 kWh per 100 km):
- Night tariff home charging: ~$2.40 per 100 km
- Gas car (35 mpg): ~$11.00 per 100 km
- Public fast charging: ~$12–15 per 100 km
Home charging at night is roughly 4.5x cheaper than gas and 5x cheaper than public fast charging.
The wallbox question
Charging speed at home depends on your setup:
| Setup | Power | Miles added per hour | Cost to install |
|---|---|---|---|
| Regular socket (Level 1) | 2–3 kW | ~4–6 mi/hr | $0 (existing) |
| Wallbox (Level 2) | 7 kW | ~25 mi/hr | $400–$1,500 |
| Wallbox (Level 2) | 11–22 kW | ~40–80 mi/hr | $600–$2,000 (may need 3-phase) |
For overnight charging, a 7kW wallbox is the sweet spot for most homes. See our guide on 7kW vs 11kW vs 22kW chargers and the best home EV chargers.
How to cut your home charging bill
- Get a night tariff. The single biggest lever. Charging during off-peak hours can halve your electricity cost.
- Schedule charging. Set the car or charger to charge only during cheap hours — most EVs let you set a departure time.
- Charge in off-peak season. Some regions have cheaper rates in spring/autumn than summer.
- Compare suppliers. In deregulated markets, switching to an EV-friendly plan can save hundreds per year.
- Add solar. If you have panels, charging from your own solar can approach zero cost (see how many panels to charge an EV).
Annual cost estimate
For a typical driver doing 15,000 km/year:
- Night tariff: ~$360/year
- Standard rate: ~$680/year
- Public fast charging only: ~$1,800/year
That's a $1,400+/year difference between best-case home charging and worst-case public charging — well worth a bit of setup effort.

FAQ
Is charging an EV at home expensive? No — it's the cheapest way to fuel any vehicle. At night-tariff rates, a full charge often costs less than $10, and running costs drop to a few dollars per 100 km.
Does home charging raise your electric bill? Yes, it adds your EV's consumption — but if you use a night tariff and schedule charging, the increase is small and still far cheaper than gas.
How much does it cost to install a home EV charger? Typically $400–$1,500 for a 7kW wallbox including installation, often reduced by grants or manufacturer offers.
The bottom line
Home charging costs $0.02–0.05 per mile with a night tariff — the cheapest motoring in existence. The setup (a tariff switch, a wallbox, and scheduled charging) pays for itself within months. If you own an EV and don't charge at home, you're leaving hundreds of dollars a year on the table.
