As electric vehicles (EVs) become more popular, many homeowners wonder how much it actually costs to charge an electric car at home.
The answer depends on three main factors:
- Your electricity rate (per kWh)
- Your car’s battery size
- How many miles you drive per month
Let’s break it down.
Quick Answer
On average, it costs:
$30 to $80 per month
to charge an electric vehicle at home in the U.S.
Annual cost typically ranges from:
$400 to $900 per year
This is usually cheaper than gasoline.
How EV Charging Cost Is Calculated
Formula:
Battery size (kWh) × electricity rate = cost per full charge
Example:
60 kWh battery
$0.16 per kWh electricity
60 × 0.16 = $9.60 per full charge
If you charge 8 times per month:
$9.60 × 8 = $76.80 per month

Cost Per Mile Comparison
Most EVs use about:
0.25 to 0.35 kWh per mile
At $0.16 per kWh:
0.30 × 0.16 = $0.048 per mile
About 5 cents per mile.
Gasoline vehicles often cost 12–18 cents per mile.
How State Electricity Rates Impact EV Costs
In low-cost states ($0.12/kWh):
Full charge ≈ $7.20
In high-cost states ($0.25/kWh):
Full charge ≈ $15.00

$500 to $2,000
Depending on electrical upgrades required.
This is separate from electricity usage cost.
