How Much Does It Cost to Charge an EV at Home? (2026, by State)

The Simple Formula for EV Charging Cost at Home

Calculating your cost to charge an EV at home comes down to a straightforward formula:

Charging Cost = (Battery Capacity in kWh × Electricity Rate per kWh) ÷ Charger Efficiency

Here's what each component means:

• Battery Capacity (kWh): How much energy your EV battery holds when empty to full
• Electricity Rate ($/kWh): What your utility company charges per kilowatt-hour (check your electric bill)
• Charger Efficiency: Energy lost during charging process (typically 88-92% for Level 2, 70-85% for Level 1)

For example, if you're charging a Tesla Model Y (about 75 kWh usable) at the U.S. average of $0.183/kWh with a Level 2 charger at 90% efficiency:

(75 kWh × $0.183) ÷ 0.90 = $15.25 per full charge

Most EV owners don't charge from completely empty to 100% daily. If you're only topping up 30 to 40 kWh at a time, you're looking at about $6 to $8 per charging session at the average rate.

Cost to charge an EV at home, by state (2026)

What a typical EV costs to charge at home in every state, at each state's average residential price for July 2026. Assumes about 31 kWh per 100 miles from the wall (28 kWh at the battery plus about 10% charging losses), a little above EPA ratings for popular EVs, which already include charging losses (a Tesla Model 3 is rated about 24 to 26, a Chevy Equinox EV about 31).

Off-peak rates change the math. PG&E's EV2-A rate in California, effective June 1, 2026, charges about 22.6¢/kWh overnight, compared with California's 33.6¢ statewide average (EV2-A also has a fixed daily base services charge). That cuts the cost of 1,000 miles from about $105 to about $70. Most large utilities offer a similar EV or time-of-use plan; see how to find your off-peak hours. Two EVs on one circuit?

Real-World Charging Costs: 2026 EV Comparison

Here's what it costs to charge popular 2026 EVs at home at the U.S. average of $0.183/kWh, using EPA efficiency ratings (measured at the wall) and approximate usable battery sizes:

Compare that with gas: at $4.35 a gallon (EIA's U.S. average for regular on October 5, 2026), a 30 mpg car spends about $1,740 on fuel for the same 12,000 miles, roughly three times what a Model 3 costs to charge at home. For a deeper dive, see whether Teslas really save you money.

Your actual costs will vary based on:

• Your local electricity rate (about 12.7¢/kWh in Louisiana to 48¢ in Hawaii; see the state table above)
• Whether you charge during peak or off-peak hours
• Your daily driving distance
• Whether you charge to 80% (recommended) vs 100%

The NeoCharge app's cost tracking dashboard automatically calculates your real charging costs by monitoring your actual energy usage and time-of-use rates, giving you precise numbers instead of estimates.

Level 1 vs Level 2 Charging: The Hidden Cost Difference

When calculating the cost to charge your EV at home, the type of charger you use makes a bigger difference than most people realize—not just in charging speed, but in actual dollars spent.

Level 1 Charging Costs (120V Standard Outlet)

• Charger Efficiency: 70-85%
• Energy Loss: 15-30% of electricity is lost as heat
• Real Cost: about $17 for a 69 kWh charge (vs about $14 at Level 2)

Example: Charging a Tesla Model 3 Standard (about 69 kWh) at $0.183/kWh:

• Level 1 at 75% efficiency: (69 × $0.183) ÷ 0.75 = $16.84
• Additional cost vs Level 2: about $2.80 per full charge

Level 2 Charging Costs (240V Dedicated Circuit)

• Charger Efficiency: 88-92%
• Energy Loss: 8-12% lost to heat and conversion
• Real Cost: about $14 for a 69 kWh charge

Example: Same Tesla Model 3 with Level 2 at 90% efficiency:

• (69 × $0.183) ÷ 0.90 = $14.03

The Math on Long-Term Savings

If you drive 12,000 miles a year in a Model 3, at the U.S. average rate:

• Level 2: about 2,900 kWh from the wall, about $534 a year
• Level 1, with roughly 15% more lost as heat: about $640 a year
• Savings with Level 2: roughly $100 a year, plus far faster charging

Frequently Asked Questions

How much does it cost to charge an electric car at home per month?

At the U.S. average of 18.3¢/kWh, 1,000 miles a month costs about $44 in a Tesla Model 3 and about $57 in a typical EV crossover, from about $40 in the cheapest states to over $100 in California and Hawaii. That's roughly 60 to 70% less than fuel for a comparable gas car at $4.35 a gallon.

Is charging an EV at home cheaper than gas?

Yes, significantly. At average prices, home charging costs about 4.5 to 6 cents a mile, while a 30 mpg gas car costs about 14.5 cents a mile at $4.35 a gallon, and a 20 mpg truck about 22 cents. Over 12,000 miles that's roughly $540 to $720 for electricity versus $1,740 to $2,600 for gas. Charging off-peak widens the gap.

Does charging an EV increase your electric bill?

Yes, by a predictable amount: about $45 to $60 a month for 1,000 miles at the U.S. average rate, more in high-rate states. That's offset by no longer buying gas, and charging off-peak lowers it further.

What's the most cost-effective way to charge an EV at home?

Combine three things: (1) charge on Level 2 rather than Level 1, which wastes less energy as heat, (2) charge during off-peak hours, and (3) switch to your utility's EV or time-of-use rate if it has one. Scheduling makes sure you never charge at peak by accident. In California, for example, PG&E's EV2-A overnight rate cuts the cost of 1,000 miles from about $105 to about $70.
