Electricity is cheaper per mile than gasoline in nearly every U.S. state, and electric cars need far less maintenance

An electric car costs between $0.03 and $0.05 per mile to charge at home, depending on your state's electricity rates. A gas car costs between $0.08 and $0.12 per mile at current pump prices. That gap widens further when you factor in maintenance: electric motors have no oil changes, spark plugs, transmission fluid, or timing belts. Over a vehicle's lifetime, the fuel and maintenance savings on an electric car typically offset the higher purchase price within five to eight years.

The real comparison is not whether electricity is cheaper than gasoline — it is — but whether the total cost of owning an electric car makes sense for your driving patterns and local electricity rates. A person who drives 40 miles a day and charges at home will see savings when ready. Someone who relies on public fast-charging networks and drives infrequently may not.

Key Takeaways

  • Home charging costs $0.03 to $0.05 per mile in most states, while gasoline costs $0.08 to $0.12 per mile at current prices.
  • Electric cars have no oil changes, spark plugs, transmission fluid, or exhaust system repairs, cutting maintenance costs by roughly 40 percent over the vehicle's life.
  • Public fast-charging networks cost more per mile than home charging but less than gas in most locations.
  • The purchase price premium for an electric car is typically recovered through fuel and maintenance savings within five to eight years of average driving.
  • Your actual savings depend on your state's electricity rates, how often you charge at home versus public chargers, and how many miles you drive annually.

How to calculate your home charging cost

Start with your electricity bill. Find the per-kilowatt-hour (kWh) rate — it appears on your monthly statement, usually between $0.10 and $0.20 per kWh depending on your state and utility. Most electric cars use between 0.2 and 0.3 kWh per mile. Multiply your rate by the car's efficiency to get your cost per mile.

Example: If your rate is $0.14 per kWh and your car uses 0.25 kWh per mile, your cost is $0.035 per mile. A 300-mile weekly commute costs about $10.50 to charge. The same distance in a gas car averaging 28 miles per gallon costs roughly $36 at $3.50 per gallon.

Some utilities offer time-of-use rates that charge less during off-peak hours (usually 9 p.m. to 6 a.m.). Charging during these windows can cut your per-mile cost by 30 to 50 percent. Check whether your utility offers this option — many do, and you may not be enrolled automatically.

Public charging networks cost more than home charging but less than gas

Fast-charging at a public network typically costs $0.25 to $0.45 per kWh, depending on the network and location. This translates to $0.05 to $0.14 per mile — still cheaper than gas in most cases, but significantly more than charging at home. Networks like Electrify America, EVgo, and Tesla Supercharger have different pricing models: some charge by the minute, others by the kWh, and some require a membership fee.

Level 2 chargers at workplaces, shopping centers, and parking lots are slower but cheaper, typically $0.15 to $0.30 per kWh. If your workplace offers free Level 2 charging, your effective fuel cost drops to nearly zero for your commute.

The key variable is how much of your charging happens at home versus on the road. Someone who charges 90 percent at home and uses public chargers only for long trips will see costs close to the home-charging rate. Someone who relies on public fast-charging for daily driving will pay closer to the higher per-mile rate.

Maintenance savings add up quickly

Electric cars have no oil, oil filters, spark plugs, timing belts, transmission fluid, or exhaust systems. These items account for the majority of routine maintenance on gas cars. Over 200,000 miles, a gas car typically costs $4,000 to $6,000 in maintenance. An electric car costs $1,500 to $2,500, mostly for tire rotation, cabin air filters, and eventual brake pad replacement (though regenerative braking means brake pads last much longer).

The one maintenance item unique to electric cars is the battery. Most manufacturers warranty the battery for eight years or 100,000 miles, and real-world failure rates are low — fewer than 2 percent of electric cars experience battery problems within the warranty period. Battery replacement outside warranty is expensive (typically $5,000 to $15,000), but this rarely happens before 150,000 miles.

Insurance costs are roughly equal between electric and gas cars of the same size and safety rating, though some insurers offer small discounts for electric vehicles. Tire wear is slightly higher on electric cars due to their weight, but the difference is marginal.

How long until fuel and maintenance savings pay for the higher purchase price

Most electric cars cost $5,000 to $15,000 more than comparable gas cars before any tax credits. A federal tax credit of up to $7,500 is available for new electric cars that meet domestic content and price requirements (the rules change yearly, so check current may be able to access). Some states offer additional credits or rebates ranging from $1,000 to $5,000.

After tax credits, the price gap narrows significantly. For someone buying a car that qualifies for the full federal credit, the net premium might be $0 to $8,000. At an average fuel and maintenance savings of $1,200 to $1,500 per year, this premium is recovered in five to eight years. Someone who drives more than 15,000 miles annually will recover it faster.

Used electric cars often cost less than used gas cars of the same age and mileage, since the initial premium has already been absorbed by the first owner. Buying used can eliminate the purchase price premium entirely while still capturing most of the fuel and maintenance savings.

Regional electricity rates matter more than you might think

Electricity costs vary widely by state. Louisiana and Oklahoma have rates around $0.10 per kWh, while California, Massachusetts, and Hawaii exceed $0.20 per kWh. This creates a real difference in your per-mile cost. In Louisiana, home charging might cost $0.025 per mile. In Hawaii, it could be $0.06 per mile — still cheaper than gas in most cases, but the savings are smaller.

If you live in a state with high electricity rates, your payback period lengthens, but the electric car is usually still cheaper to operate than a gas car. The exception is if you rely heavily on public fast-charging, where the per-kWh markup is the same everywhere and can make the per-mile cost competitive with gas.

Some utilities also charge demand fees or time-of-use rates that affect your total bill. If you charge during peak hours when your utility charges premium rates, your per-mile cost rises. Shifting charging to off-peak hours can cut this significantly.

The break-even point depends on your driving patterns

Someone who drives 5,000 miles per year will take much longer to recover the purchase price premium than someone who drives 20,000 miles per year. The fuel and maintenance savings are proportional to miles driven, so low-mileage drivers should be cautious about the upfront cost.

Conversely, high-mileage drivers see the payback period shrink dramatically. A person driving 25,000 miles annually could recover a $10,000 premium in four years through fuel and maintenance savings alone. For commercial drivers or people with long commutes, an electric car often makes financial sense from day one.

Your driving pattern also affects which charging option makes sense. If you drive fewer than 150 miles per day, home charging covers all your needs. If you regularly drive 300+ miles in a day, you will use public fast-charging, which costs more per mile but is still usually cheaper than gas.

Frequently Asked Questions

What if I don't have a home charger or driveway?

Apartment dwellers and people without dedicated parking can still own electric cars, but the economics change. Relying on public charging increases your per-mile cost to $0.08 to $0.14, narrowing or eliminating the savings advantage over gas. Some apartments and workplaces offer Level 2 chargers; if yours does, the math improves significantly. Check whether your building or employer has charging before buying.

Do electric cars cost more to insure?

Insurance costs are roughly the same as gas cars of comparable size and safety rating. Some insurers offer small discounts for electric vehicles, while others charge slightly more due to higher repair costs for specialized parts. Get quotes from your insurer before assuming a cost difference.

Will my electricity bill spike if I charge an electric car?

Your bill will increase by the cost of charging, but the amount is predictable. Charging a typical electric car costs $30 to $50 per month if you drive 1,000 miles monthly. This is far less than you would spend on gas for the same distance. If you shift charging to off-peak hours, the increase is even smaller.

What happens to fuel savings if gas prices drop?

The savings shrink but rarely disappear entirely. Even if gas fell to $2 per gallon, electricity would still be cheaper per mile in most states. The maintenance savings — which are not affected by gas prices — remain substantial and account for roughly one-third of the total operating cost advantage.

Are there states where gas is cheaper than electricity?

No. Even in states with the highest electricity rates and lowest gas prices, electricity is cheaper per mile. The gap is smallest in Hawaii and largest in Louisiana, but the direction is consistent across all 50 states.
