EV Charging Cost in the United States — What You'll Actually Pay

The cost of charging an EV comes down to a simple calculation: the amount of energy your vehicle needs multiplied by the price you pay per kilowatt hour (kWh) of electricity.

For example, if your EV uses 26 kWh of electricity to travel 100 miles and you pay $0.18 per kWh at home, the electricity cost for that 100 miles is $4.68. A full charge of a 100 kWh battery at the same rate would cost $30.00.

The two main variables that determine your charging cost are your vehicle's energy efficiency and the electricity price at the point of charge. Everything else — battery size, distance driven, charge frequency — flows from those two numbers.

Electricity prices vary significantly depending on where and when you charge. The table below shows the range of prices US EV owners typically encounter.

Home charging is where most US EV owners do the majority of their charging, and it is usually the cheapest option by a significant margin.

Standard home electricity rate

On a standard residential electricity plan, a typical rate is around $0.18 per kWh. At this rate, charging a 100 kWh battery from empty to full would cost $30.00. In practice, most owners charge from around 10% to 80%, which uses about 70 kWh and costs around $21.00.

Off peak home charging

Many electricity plans offer a cheaper off peak rate for electricity used outside of peak hours, typically overnight. A common off peak rate is around $0.16 per kWh. Charging overnight on this rate reduces the cost of 100 miles of driving from $4.68 to $4.16.

Dedicated EV tariff

Some utilities in the United States offer a dedicated EV charging tariff as low as $0.13 per kWh. These tariffs are typically available during overnight hours as part of a time-of-use plan. At $0.13 per kWh, the cost of 100 miles drops to just $3.38 — a fraction of what a gas vehicle costs over the same distance.

If you charge at home regularly, switching to an off peak or dedicated EV tariff can make a meaningful difference to your annual running cost.

Public charging is more expensive than home charging because the price includes the cost of installing, maintaining and operating the charging infrastructure.

Public AC charging

Public AC chargers, commonly found at shopping centres, workplaces and car parks, typically charge around $0.32 per kWh. These chargers are slower — usually 7 kW to 22 kW — but are useful for topping up while you are parked for a longer period. At $0.32 per kWh, 100 miles of driving costs around $8.32.

DC fast charging

DC fast chargers are the most practical option for long distance travel and quick top-ups. They typically charge at 50 kW to 150 kW and can add significant range in 20 to 40 minutes. Prices are usually around $0.48 per kWh, which puts the cost of 100 miles at around $12.48.

Ultra rapid DC charging

Ultra rapid chargers operate at 250 kW or more and can charge compatible vehicles significantly faster than standard DC fast chargers. Pricing is typically around $0.56 per kWh, which puts the cost of 100 miles at around $14.56. These chargers are most commonly found along major highways and at high-traffic charging sites.

Even at ultra rapid DC prices, driving an EV can still be cheaper per mile than gas for many vehicles, particularly when fuel prices are high. However, relying exclusively on public fast charging would significantly reduce the cost advantage that home charging provides.

The difference between home and public charging costs is substantial. This comparison shows the annual electricity cost for the same vehicle and distance at different charging prices.

The gap between the cheapest and most expensive charging option can be well over $1,500 per year for the same vehicle and distance. This is why charging behaviour has a large impact on the true running cost of an EV.

To work out your own charging cost, you need two numbers: your vehicle's energy efficiency (in kWh per 100 miles) and the electricity price you pay (in $ per kWh).

Step 1 — Find your vehicle's efficiency

Your vehicle's energy consumption is usually listed in the specifications as kWh per 100 miles. A typical figure for a standard EV in the United States is around 26 kWh per 100 miles. Smaller, more efficient vehicles may use 12 to 23 kWh per 100 miles, while larger SUVs and performance vehicles may use 18 to 35 kWh per 100 miles.

Step 2 — Find your electricity price

Check your electricity bill for the rate you pay per kWh. If you have a time-of-use plan, note the off peak rate — this is the rate you will pay if you charge overnight. If your retailer offers a dedicated EV tariff, that rate may be even lower.

Step 3 — Calculate

Multiply your efficiency by your electricity price to get the cost per 100 miles. For example, 26 kWh per 100 miles × $0.18 per kWh = $4.68 per 100 miles. To get the annual cost, multiply by your annual distance and divide by 100.

You can also use the calculators below to run the numbers for your specific situation. If you select your vehicle and set your electricity rate in the My EV panel, every calculator and reference table across the site updates automatically to show results tailored to your vehicle and the price you actually pay.

Charge at home as much as possible

Home charging is almost always the cheapest option. Most EV owners do the majority of their charging at home overnight and use public chargers mainly for convenience or long distance travel.

Use off peak or EV-specific tariffs

Switching to an off peak tariff or a dedicated EV charging tariff can cut your charging cost significantly. At $0.13 per kWh on a dedicated EV tariff, you could charge for less than $200 per year based on typical driving distances.

Charge to 80% for everyday use

Charging to around 80% rather than 100% for daily driving is common practice for many EVs. It reduces time spent at slower charging speeds near the top of the battery and is generally better for long-term battery health. Saving the full charge for when you need the extra range keeps everyday charging fast and efficient.

Use public fast charging selectively

DC fast charging is convenient but costs significantly more per kWh than home charging. Reserving it for road trips and top-ups when you genuinely need it helps keep your average charging cost low.

Even at the most common home electricity rate, an EV is substantially cheaper to run per mile than a gas vehicle.

The annual saving for an EV charged at home on a standard rate compared with a medium gas car is significant. On a dedicated EV tariff, that saving increases further.
