How Much Does It Cost to Charge an Electric Vehicle?

The cost to charge an EV depends on three factors: your electricity rate, your vehicle's efficiency (kWh/100 miles), and the type of charger you use. Home charging at Level 2 (240V) is typically the most cost-effective at $0.04-0.06 per mile in most US states.

DC fast charging is 2-3x more expensive per kWh but can add 200+ miles in 30 minutes. Public Level 2 stations typically charge $0.20-0.35/kWh. The national average residential electricity rate is approximately $0.16/kWh.

Even at higher DC fast charging rates, EVs are significantly cheaper to fuel than comparable gas vehicles. The average American drives 1,000 miles per month and would spend roughly $40-80 on electricity vs $120-180 on gasoline.

Frequently Asked Questions

How much does it cost to charge an electric car?
The average cost to fully charge an EV in the US is $10-15 for home charging using residential electricity rates. At public DC fast chargers, expect $15-30 per session. The exact cost depends on your local electricity rate, battery size, and charging speed.
How much does it cost to charge at a Tesla Supercharger?
Tesla Supercharger rates vary by location but typically range from $0.25-0.50 per kWh. A full charge on a Tesla Model 3 Long Range (75 kWh battery) costs approximately $19-38 at a Supercharger.
Is it cheaper to charge an EV at home or at a public charger?
Home charging is significantly cheaper — typically 60-70% less than public DC fast charging. The average US residential rate is about $0.16/kWh compared to $0.35-0.60/kWh at public fast chargers. Charging at home overnight on time-of-use rates can save even more.
How much electricity does an EV use per month?
The average EV driven 1,000 miles per month uses about 300-350 kWh of electricity. At the US average rate of $0.16/kWh, that costs roughly $48-56/month — compared to $120-180/month in gasoline for an equivalent gas car.
What is the cheapest state to charge an EV?
Louisiana, Washington, and Idaho have the lowest residential electricity rates in the US at around $0.10-0.12/kWh. Hawaii and Connecticut are the most expensive at $0.35-0.45/kWh. Use our calculator with your actual state rate for precise costs.
