Home Charging: The Cheapest Option
If you can charge at home, most of your charging will cost $0.10–0.18/kWh in the USA (average residential electricity rate) and €0.25–0.35/kWh in Europe. For a 60 kWh battery, that's $6–11 for a full charge in the USA, or €15–21 in Europe.
With a time-of-use (TOU) rate or dynamic tariff (e.g. Tibber, Octopus Energy), you can charge overnight at $0.05–0.08/kWh in the USA or €0.15–0.20/kWh in Europe – roughly 70% cheaper than gasoline equivalent.
Public Level 2 Charging (AC, 7–22 kW)
Public Level 2 charging is typically priced per hour or per kWh:
- USA: $0.20–0.35/kWh or $1–2/hour (ChargePoint, Blink)
- Europe: €0.30–0.50/kWh (varies widely by country)
- Free: Many destinations (hotels, IKEA, supermarkets) still offer free Level 2 charging
DC Fast Charging (50–350 kW)
Fast charging costs more per kWh – you pay for speed and convenience:
| Network | Price | With Membership |
|---|---|---|
| Tesla Supercharger (USA) | $0.25–0.48/kWh | Included with some models |
| Electrify America | $0.48/kWh | $4/mo → $0.36/kWh |
| EVgo | $0.27–0.45/kWh | $7.99/mo |
| Ionity (Europe) | €0.79/kWh | €17.99/mo → €0.35/kWh |
| EnBW (Germany) | €0.59/kWh | €9.99/mo → €0.49/kWh |
EV vs. Gasoline: Real Cost Comparison
At US average electricity ($0.16/kWh) and average EV consumption (3.5 miles/kWh):
- EV home charging: ~$0.046 per mile
- EV fast charging: ~$0.137 per mile (Electrify America)
- Gasoline ($3.50/gal, 30 mpg): ~$0.117 per mile
Bottom line: Home charging saves 60–70% vs gasoline. DC fast charging is comparable to or slightly more than gasoline – but still you're paying for speed, not for the daily commute.
