EV Charging Prices by State
EV charging prices by state can be very different because electricity costs are not the same everywhere. A full charge may cost less in one state and more in another, even for the same electric vehicle. This guide helps you understand those differences in a simple way. You can compare home charging costs, see estimated full battery prices, and check the cost to drive 100 miles.
It also explains what affects your real charging bill, including your utility rate, vehicle efficiency, driving habits, and charging time.

What This Page Shows
Home EV charging cost by state based on average residential electricity rates from EIA.gov. Calculations use an 82 kWh battery (Tesla Model 3 equivalent) and 22.9 kWh per 100 miles.
Cost per kWh
The average electricity rate in each state, in cents per kilowatt-hour.
Full battery cost
Estimated cost to charge an 82 kWh battery from empty to full.
Cost per 100 miles
How much you may spend in electricity to drive 100 miles. Best for daily planning.
These are home charging estimatesbased on residential electricity rates. Public DC fast chargers typically cost 2–3× more. Costs per 100 miles assume ~22.9 kWh/100 mi.

How EV Charging Cost Is Calculated
The basic charging cost formula is simple:
Battery size (kWh) × electricity rate ($/kWh) = estimated charging costCost per 100 miles is also useful because many drivers do not think in battery size — they think in miles. If you know how much it costs to drive 100 miles, you can estimate your weekly or monthly charging cost more easily.
Monthly estimate method
- Check how many miles you drive each month
- Divide that number by 100
- Find the estimated cost per 100 miles for your state
- Multiply both numbers for a simple monthly estimate
For example: 1,200 miles ÷ 100 = 12. Then 12 × cost per 100 miles = your monthly home charging estimate.
Why Your Real Cost May Be Different
The numbers on this page are estimates. Your real charging cost may be a little higher or lower because every driver has a different situation.
Charging losses are normal — some electricity is lost during the charging process. In simple words, not every bit of power from the wall goes into the battery.
Why Electricity Rates Change by State
Electricity prices are different because each state has its own energy costs, utility rules, grid expenses, and power sources. This does not mean an EV is a bad choice in a higher-cost state — it only means you should check your local electricity rate before estimating your savings.
Local Utility Costs
Each state has its own energy costs and utility rules. These directly affect the rate you pay per kWh.
Power Sources
States that rely on hydroelectric, nuclear, or other lower-cost energy sources often have lower electricity rates.
Grid Expenses
Infrastructure, maintenance, and grid management costs are built into your electricity rate and vary by region.
Utility Regulations
State policies, rate structures, and utility rules all influence how much residential electricity costs.
Home Charging and Public Charging Are Different
Home charging
Uses your residential electricity rate. You plug in your car at home, and the cost is added to your electric bill. Usually the most affordable option for regular charging.
Public charging
Some public chargers cost more, especially fast chargers. A public charging station may also include extra fees, parking costs, idle fees, or membership pricing.
If you mostly charge at home, use home charging estimates for your budget. If you depend on public chargers, your real cost may be higher.
Driving Habits Affect EV Energy Use
Fast acceleration, high speeds, heavy cargo, and long highway trips can use more battery power. You can help reduce energy use by:
Drive smoothly
Avoid hard acceleration
Keep tires properly inflated
Remove extra weight when possible
Use your EV's efficiency settings when helpful
How to Lower Home EV Charging Costs
You may not control your state's electricity rate, but you may still have ways to reduce your charging cost.
One of the easiest options is charging during cheaper hours. Some utility companies offer time-of-use pricing — electricity may cost less at night and more during busy hours.
If your utility offers lower off-peak rates, you can schedule your EV to charge overnight. Many electric vehicles and home chargers allow scheduled charging. You can plug in the car, set the charging time, and let it charge when electricity is cheaper.
When This State Comparison Is Most Useful
Common Mistakes to Avoid
Looking only at the full charge cost — most drivers do not fully drain the battery before charging
Using public fast charging prices as your normal cost if you mostly charge at home
Ignoring vehicle efficiency — a less efficient EV can cost more to drive even at the same electricity rate
Forgetting charging losses — not every bit of power from the wall goes into the battery
