Calculate how much it costs to charge your electric vehicle at home or at a public charger.
Charging an EV at home costs significantly less than fueling a gas car. The average US electricity rate is around $0.16/kWh, meaning a full 75 kWh charge costs about $12 at home versus $26+ at a public fast charger.
Home charging (Level 2) is the most cost-effective option at $0.12–0.20/kWh. Public DC fast chargers typically cost $0.30–0.50/kWh — still cheaper than gas for most drivers, but 2–3x more than home charging.
At $0.16/kWh and 4 miles/kWh, you're paying about $0.04 per mile. A gas car getting 30 MPG at $3.50/gallon costs about $0.12 per mile — roughly 3x more expensive.
