With soaring gasoline prices, millions of drivers are switching to Electric Vehicles (EVs) hoping to eliminate fuel expenses. But electricity isn't free, and the true cost of charging an EV depends heavily on your local residential utility kilowatt-hour (kWh) rate and whether you charge at home or at commercial DC fast-charging stations.
Let's calculate the real cost per mile driven in an EV versus an efficient internal combustion gasoline vehicle.

The Math of EV Charging Costs
To determine how much it costs to fully charge an electric car at home:
- Battery Capacity (kWh): For example, a Tesla Model Y has approximately a 75 kWh battery pack.
- Residential Electricity Rate ($/kWh): The US national average is around $0.16 per kWh (varying from $0.11 in low-cost states to $0.32 in California).
- Full Charge Cost Formula: Battery Capacity x Electricity Rate.
Example: 75 kWh x $0.16 = $12.00 for a full 300-mile charge. Cost per mile: $12.00 / 300 miles = $0.04 per mile (4 cents).
The Math of Gasoline Vehicles
Now compare this to a modern 28 MPG gasoline sedan:
- Fuel Price: $3.60 per gallon.
- Miles Per Gallon: 28 MPG.
- Cost per mile: $3.60 / 28 = $0.128 per mile (nearly 13 cents).
The Verdict: Annual Fuel Savings
For an average driver traveling 12,000 miles per year:
- Electric Vehicle Charging: 12,000 miles x $0.04 = $480.00 per year.
- Gasoline Vehicle Fuel: 12,000 miles x $0.128 = $1,536.00 per year.
- Net Annual Savings: $1,056.00 per year saved on fuel alone!
Public Fast Chargers vs Home Charging
Beware: Public DC fast-charging networks (such as Electrify America or EVgo) often charge $0.40 to $0.50 per kWh. At those peak rates, public EV charging costs roughly the same as gasoline. To capture the full economic advantage of an EV, charging overnight on residential off-peak tariffs is essential.
