EV Charging Cost Calculator

EV charging cost is the electricity you buy multiplied by the price you pay for it. At the U.S. residential average of 18.31¢ per kWh (EIA, July 2026), driving 1,000 miles a month at 30 kWh per 100 miles costs about $54.93, or 5.49¢ a mile. The same miles in a 25.5 mpg gasoline car at $4.28 a gallon cost about $168.00.

What changes the number

  • Where you live. State averages ran from 12.72¢ in Louisiana to 48.00¢ in Hawaii, about 3.8 times apart.
  • Your own price. Your tariff, time-of-use period and usage tier can sit well above or below the state average.
  • Where the kWh figure comes from. EPA labels already include charging losses, so do not add them again.
  • Where you plug in. Public prices come from the station, billed per kWh or per minute, often with fees.

How much does it cost to charge an electric car?

Energy use is held at 1,000 miles and 30 kWh per 100 miles, so only the price changes. A single home charge from 20% to 80% of a 75 kWh battery costs $9.16 at the U.S. average.

How the cost is calculated

Purchased kWh = miles ÷ 100 × wall kWh per 100 miles

From a battery figure: kWh ÷ efficiency

Cost = purchased kWh × price per kWh + fees

EPA says its electric efficiency values include charging losses and assume Level 2 AC charging. Adding a second loss factor to a label figure overstates the cost, so convert only battery-side figures, and only once.

Battery size sets what a full charge costs; efficiency sets what a mile costs. For your exact car, use the EPA figure for the right model year and trim in the charging cost by car tool.

EV charging cost by state

The same driving costs about 3.8 times as much in Hawaii as in Louisiana. Prices are EIA July 2026 residential averages, the same references used by the state and home-charging tools, at 1,000 miles and 30 kWh per 100 miles.

Home and public charging are priced differently

At home: your utility sets the price

Level 1 (120-volt outlet) and Level 2 (208 to 240-volt circuit) both draw from your meter. What matters is the price for the hours and usage tier you charge in. One study summarized by Recurrent measured average efficiency of 83.8% on Level 1 and 89.4% on Level 2.

Time-of-use rates · Level 1 vs Level 2

In public: the station sets the price

Networks bill per kWh or per minute, and may add session, idle, parking or membership charges. Prices change by site, time and account, so use the quote in the app or on the charger rather than a network average.

EV charging cost vs gas, per mile

Home charging, U.S. average

5.49¢

per mile at 30 kWh/100 mi and 18.31¢ per kWh

Gasoline at 25.5 mpg

16.80¢

per mile at $4.284 a gallon, EIA week of October 19, 2026

At these inputs, electricity would have to cost about $0.56 per kWh before energy per mile matched gasoline; even in Hawaii, home charging is 14.40¢ a mile. The 25.5 mpg figure is EPA's model year 2024 new-vehicle average of 27.2 mpg, less the 1.7 mpg that plug-in models add. This compares driving energy only. EV vs gas calculator · Ownership calculator

EV charging cost questions

How much does it cost to charge an electric car?

It depends on how much electricity you buy and what you pay for it. At the U.S. residential average of 18.31¢ per kWh (EIA, July 2026), driving 1,000 miles a month at 30 kWh per 100 miles costs about $54.93 a month, or 5.49¢ a mile. Adding 45 kWh to a battery at home, assuming 90% meter-to-battery efficiency, costs about $9.16.

Build a home charging budget

How is EV charging cost calculated?

Multiply the kWh you buy by the price you pay per kWh. From miles, purchased kWh equals miles divided by 100, times wall kWh per 100 miles. From energy added to the battery, divide by an explicit charging efficiency once. Session, idle or membership fees are added separately.

Cost per mile calculator

Do I add charging losses to an EPA kWh per 100 miles label?

No. EPA electric efficiency already includes charging losses, so the label is wall energy. Only a battery-side figure, such as a trip display, needs a separate meter-to-battery efficiency assumption.

Are the state rates my current utility price?

No. They are EIA July 2026 residential average references: total residential revenue divided by kWh sold in each state. Your tariff, time-of-use period, usage tier and taxes set your own price. Choose "My bill or a station quote" in the calculator to enter it.

Time-of-use rates guide

Is charging an EV cheaper than buying gas?

For energy alone, usually. Home charging at the U.S. average works out to 5.49¢ a mile at 30 kWh per 100 miles. A 25.5 mpg gasoline car at $4.28 a gallon (EIA, week of October 19, 2026) costs 16.80¢ a mile. Electricity would need to cost about $0.56 per kWh before the two matched. Purchase, insurance and maintenance are separate questions.

EV vs gas calculator

Is home charging always cheaper than public charging?

No. Compare your home price with the station quote, plus any session, idle, parking or membership fees. To price a public stop, multiply the kWh on the receipt by the price per kWh: 45 kWh at $0.35 is $15.75 before fees or tax. If the station bills per minute, use the minutes instead.

Public charging session calculator

Does cold weather raise charging cost?

Yes. Citing AAA testing at 20°F with the heater on, fueleconomy.gov says EV efficiency can fall about 39% in mixed driving. That is about 1.6 times the energy for the same miles, so a $54.93 month could approach $90.05 at the U.S. average price.

How often are these numbers updated?

Electricity prices follow each EIA Electric Power Monthly release. This page uses July 2026 data released on September 24, 2026; the next release is August 2026 data, scheduled by EIA for the end of October 2026. The gasoline comparison uses EIA's weekly U.S. regular price, currently the week of October 19, 2026.
