Is it cheaper per mile to drive an electric car?

[StCarson]

For most drivers, yes, driving an electric car is significantly cheaper per mile than a gasoline car. The core savings come from lower energy and maintenance costs. Based on 2025 U.S. averages, home-charging an EV costs about $0.04 to $0.06 per mile in energy, while fueling a comparable gas car costs about $0.10 to $0.13 per mile. This means the EV can save roughly $600 to $1,200 annually on fuel alone for a driver covering 15,000 miles.

The calculation hinges on your local electricity and gasoline prices, as well as vehicle efficiency. Using national averages (gasoline at $3.50/gallon, electricity at $0.16/kWh), here’s a typical comparison:

Vehicle Type	Example Model	Efficiency	Energy Cost per Mile (Est.)
Electric Vehicle	Tesla Model 3 RWD	4.0 mi/kWh	$0.04 ($0.16 ÷ 4.0)
Gasoline Sedan	Toyota Camry Hybrid	50 mpg	$0.07 ($3.50 ÷ 50)
Gasoline SUV	Honda CR-V	30 mpg	$0.12 ($3.50 ÷ 30)

Electricity rates vary dramatically. A driver in Washington state paying $0.10/kWh might see a per-mile cost as low as $0.025, while someone in California paying $0.30/kWh could pay $0.075 per mile—still competitive with or cheaper than gas in most cases. Public fast-charging rates increase the cost, typically bringing the per-mile price to between $0.10 and $0.20, which can temporarily erase the fuel savings advantage.

Maintenance expenses further tilt the balance in favor of EVs. Industry data from sources like Consumer Reports indicates EVs have fewer moving parts—no oil changes, spark plugs, or complex transmissions. This results in average maintenance and repair costs being 30% to 50% lower over the vehicle's lifetime compared to internal combustion engine vehicles.

The total cost per mile must also consider depreciation, insurance, and taxes. Historically, some EVs depreciated faster, but market data from providers like Hagerty now shows that popular models from Tesla, Ford, and Hyundai are retaining value competitively. Insurance can be 10-20% higher for EVs due to repair complexity, partially offsetting other savings.

For a holistic view, a 2025 analysis by the U.S. Department of Energy’s “eGallon” tool consistently shows that fueling a vehicle with electricity costs less than half the price of fueling with gasoline in nearly all states. This reinforces the per-mile cost advantage under typical home-charging conditions.

Your personal savings depend on your driving profile. The EV’s cost advantage maximizes for high-mileage drivers who can charge overnight at home. If you rely primarily on expensive public fast chargers or drive very few miles annually, the financial benefit narrows.

I switched to an electric car two years ago for my daily 40-mile commute. My main takeaway? My “fuel” bill got cut by more than half. I charge almost exclusively in my garage overnight. On my utility’s off-peak plan, I pay about 9 cents per kWh.

My car uses around 3.5 miles per kWh, so my cost per mile is just over 2.5 cents. My old sedan got 28 mpg, and with gas around $3.80 here, that was about 13.5 cents per mile. I’m saving nearly 11 cents every single mile I drive. It adds up fast—over $1,500 a year just in energy for my commute. The savings are real and immediate if you have a place to plug in at home.

Let’s break down the math from a different angle, focusing on total energy consumption. It’s not just about price per gallon versus price per kilowatt-hour; it’s about how efficiently each vehicle converts that energy into motion.

Electric motors are inherently more efficient than gasoline engines. A typical EV converts over 85% of the electrical energy from the grid to power at the wheels. A gasoline car only converts about 20-30% of the energy in fuel; the rest is lost as heat.

This fundamental efficiency gap is why even when electricity is somewhat expensive, the EV often wins on cost per mile. The gas car needs to burn a lot of costly fuel just to overcome its own inefficiency.

So when you see that an efficient gas hybrid gets 50 mpg and an EV gets the equivalent of 100+ MPGe, that MPGe figure is highlighting this efficiency advantage. The per-mile cost difference is a direct financial reflection of that engineering reality.

As a mechanic, I see the cost story from the maintenance side. People focus on fuel, but what comes into my shop tells the rest of the tale.

Electric vehicles simply have fewer things that wear out or need regular service. No engine oil to change every 5,000 miles. No timing belts, mufflers, or fuel injectors to fail. Brake pads last much longer because of regenerative braking.

For a gasoline car, routine maintenance like oil changes, coolant flushes, and spark plug replacements adds a steady stream of costs—easily $150 to $300 per year on average, even without major repairs. For an EV, that annual maintenance cost for the first several years is often under $100, mostly for tire rotations and cabin air filters.

This difference directly lowers the true cost per mile of ownership, beyond just the energy bill.

My decision to go electric was a spreadsheet exercise. I compared total ownership over five years, not just monthly payments. The higher upfront price of the EV was a hurdle, but the per-mile savings closed the gap.

I factored in a $7,500 federal tax credit, my state’s $2,000 rebate, and my local utility’s $500 charging incentive. Then I projected fuel costs (EV at 4 cents/mile vs. gas at 12 cents/mile) and lower maintenance. I also used industry valuation guides to estimate resale value.

The result? The total five-year cost for the EV I wanted was within a few thousand dollars of a comparable gas model. Given that I drive about 20,000 miles a year, the lower operating costs will likely make the EV the cheaper option by year four. The key is to run your own numbers with your specific incentives, utility rate, and driving habits. The per-mile advantage exists, but you have to calculate if it’s enough to offset the initial price difference for your situation.
