Calculate electric vehicle home charging costs, cost per full 100% charge, cost per mile, and annual fuel savings compared to a gas-powered vehicle.
Frequently Asked Questions
How much does it cost to fully charge an electric car at home?
At the US national average residential electricity rate of $0.16 per kWh, fully charging a typical 75 kWh battery pack (like a Tesla Model Y) from 0% to 100% costs approximately $13.30, providing roughly 260 to 300 miles of range.
How much cheaper is driving an EV compared to gasoline?
Driving an electric vehicle typically costs between $0.04 and $0.05 per mile, compared to $0.13 to $0.16 per mile for a 28-MPG gasoline car at $3.65/gal. The average driver traveling 13,500 miles annually saves $1,000 to $1,500 every year.
What is the charging efficiency loss on home Level 2 chargers?
Level 2 (240V) home AC charging operates at approximately 88% to 92% efficiency due to heat dissipation in the on-board AC-to-DC vehicle charger, requiring ~83 kWh of grid electricity to fill a 75 kWh battery.
How do time-of-use (TOU) rates lower EV charging costs?
Many US electric utilities offer special EV night rates between midnight and 6 AM as low as $0.05 to $0.09 per kWh. Scheduling your EV to charge overnight on these rates can reduce annual charging costs below $400/year.
