Understanding Home EV Charging

How Much Does It Cost to Charge an Electric Car?

The cost to charge an EV at home depends on three factors: your vehicle's efficiency, how much you drive, and your local electricity rate. Most EV owners spend $30-60 per month on home charging - significantly less than gasoline.

Level 1 vs Level 2 Charging: What New EV Owners Should Know

Every EV comes with a Level 1 charger that plugs into a standard 120V outlet. It works, but it's slow - adding only 3-5 miles of range per hour. A Level 2 charger (240V) adds 25-30 miles per hour, meaning you can fully charge overnight.

Is an Electric Car Cheaper Than Gas?

For most drivers, yes. Electricity costs roughly $0.04-0.06 per mile, while gasoline costs $0.10-0.15 per mile. Use our calculator above to see your specific savings.

What to Know Before Buying an EV

Consider your daily commute, home charging options, and local electricity rates. If you drive less than 200 miles per day and can charge at home, an EV likely makes financial sense.
