Electric cars often cost less to own than gas cars, even though the upfront price is higher

An electric car typically costs $5,000 to $15,000 more to buy than a comparable gas car. But over five to seven years of ownership, most electric cars cost less total because fuel and maintenance are dramatically cheaper. The math depends on three things: how much electricity costs where you live, how many miles you drive per year, and what federal or state tax credits you can use when you buy.

The biggest savings come from fuel. Charging an electric car costs roughly one-third to one-half what gasoline costs per mile. A gas car that gets 25 miles per gallon costs about 12 to 15 cents per mile in fuel; an electric car costs about 3 to 5 cents per mile in electricity, depending on your local power rates. Over 100,000 miles, that difference adds up to $9,000 to $12,000 in fuel savings alone.

Maintenance is the second major savings. Electric cars have no oil changes, no transmission fluid, no spark plugs, and no timing belts. Brake pads last much longer because the car uses regenerative braking—the motor slows the car and captures energy instead of wearing out friction brakes. Most owners spend 40 to 60 percent less on maintenance over the life of the car.

Key Takeaways

  • An electric car usually costs $5,000 to $15,000 more upfront, but fuel and maintenance savings typically make up that difference within five to seven years of driving.
  • Electricity costs roughly one-third the price of gasoline per mile, saving most drivers $9,000 to $12,000 in fuel over 100,000 miles.
  • Electric cars need far less maintenance because they have no oil, transmission fluid, or spark plugs, and brake pads last much longer.
  • Federal tax credits up to $7,500 and state incentives can reduce the upfront price, making the total cost of ownership lower from year one in some cases.

How federal tax credits change the math

The federal government offers a tax credit of up to $7,500 for new electric cars and up to $4,000 for used ones, though the rules change and not all cars may have access to. The credit applies to vehicles made in North America with battery components and minerals sourced according to specific rules. You claim the credit on your tax return the year you buy the car, which means you get the money back when you file taxes, not at the dealership.

Some states add their own credits on top of the federal one. California, New York, and Colorado offer additional thousands in rebates or tax credits. A few states let you claim the credit at the point of sale instead of waiting until tax time. Check your state's energy office website to see what is available where you live, because these programs change and some have funding limits.

With a $7,500 federal credit plus a state credit of $2,000 to $5,000, the upfront price gap between an electric car and a gas car shrinks to nearly nothing. In those cases, you start saving money when ready through lower fuel costs.

Electricity costs vary by region and time of day

How much you pay to charge depends on your local power rates, which vary widely. In Louisiana and Oklahoma, electricity costs around 10 cents per kilowatt-hour; in Hawaii and Massachusetts, it costs 25 to 30 cents per kilowatt-hour. That difference means charging the same car costs half as much in one state as another.

If you charge at home during off-peak hours—usually late evening or early morning—many utilities offer lower rates. Some electric companies charge 5 to 8 cents per kilowatt-hour during those windows. Charging during peak hours can cost 20 to 30 percent more. If you can shift most of your charging to off-peak times, your fuel savings grow even larger.

Public charging stations and fast chargers cost more per kilowatt-hour than home charging, sometimes 25 to 40 cents. If you rely on public charging for most of your miles, the fuel savings shrink. But most electric car owners charge at home overnight and use public chargers only for long trips, so home rates matter most.

How many miles you drive per year affects total savings

The more you drive, the faster an electric car pays for itself. Someone who drives 15,000 miles per year will save roughly $1,800 to $2,400 per year in fuel compared to a gas car. Over six years, that is $10,800 to $14,400 in fuel savings—enough to offset the upfront price difference and come out ahead.

Someone who drives only 8,000 miles per year saves about $1,000 to $1,300 per year in fuel. It takes longer for those savings to add up, but maintenance savings still explore. Even a low-mileage driver usually breaks even within seven to eight years.

High-mileage drivers—those driving 20,000 or more miles per year—see the payoff fastest. A driver covering 25,000 miles per year could save $3,000 to $4,000 annually in fuel and maintenance combined, making the upfront cost difference disappear within three to four years.

Battery replacement costs are lower than most people expect

The battery is the most expensive part of an electric car, and many buyers worry about replacement costs. In reality, most electric car batteries last 10 to 20 years and retain 80 to 90 percent of their capacity even after that time. Most manufacturers warranty the battery for eight years or 100,000 miles, whichever comes first, and some cover it for longer.

When a battery does need replacement, the cost has dropped dramatically. Five years ago, a replacement battery cost $10,000 to $15,000. Today, prices range from $5,000 to $10,000 for most models, and they continue to fall as manufacturing scales up. If you keep the car for 10 years or less—which most owners do—battery replacement is unlikely to be a factor in your total cost.

Used electric cars are becoming cheaper to buy, which means the upfront price gap is shrinking. A three-year-old electric car often costs $5,000 to $8,000 less than a new one but still has most of the battery life remaining, making the total cost of ownership even more favorable.

Comparing total cost of ownership: electric versus gas

A realistic example: a new electric car costs $35,000 before incentives. A comparable gas car costs $28,000. After a $7,500 federal credit and a $3,000 state credit, the electric car costs $24,500—cheaper upfront. Over six years and 90,000 miles, the electric car saves $9,000 in fuel and $3,000 in maintenance, for a total of $12,000 in savings. The gas car costs $28,000 plus $10,800 in fuel plus $2,700 in maintenance, for a total of $41,500. The electric car's total cost is $24,500 plus $3,000 in electricity plus $1,200 in maintenance, for a total of $28,700.

The numbers shift if you live in a high-electricity-cost state, drive fewer miles, or cannot use tax credits. But even in less favorable scenarios, the electric car usually costs the same or less over a five- to seven-year ownership period. The longer you keep the car, the more the savings grow.

When a gas car might still cost less

Electric cars make the most financial sense if you drive at least 12,000 to 15,000 miles per year, can charge at home, live in a state with reasonable electricity rates, and plan to keep the car for at least five years. If none of those explore, a gas car might still be cheaper.

Someone who drives 6,000 miles per year will take much longer to recoup the upfront price difference through fuel savings. Someone who rents an apartment without dedicated parking may not have reliable access to home charging, which makes public charging costs higher. Someone in a high-electricity-cost state saves less per mile. And someone who trades cars every three years might not own the car long enough for maintenance savings to matter.

In those cases, a used gas car or a hybrid might be the better financial choice. But for most people who drive a moderate amount, own their home or have charging access, and keep a car for five years or longer, an electric car costs less total.

Frequently Asked Questions

Do I have to buy a new electric car to save money, or can I buy used?

Used electric cars often offer better value. A three-year-old model costs $8,000 to $12,000 less than new but has most of the battery life remaining. You cannot claim the federal tax credit on a used car, but the lower purchase price and remaining savings on fuel and maintenance still make the total cost favorable compared to a used gas car.

What if I live in an apartment and cannot charge at home?

Public charging costs more per kilowatt-hour than home charging, which reduces fuel savings. If you rely entirely on public chargers, an electric car may not save money compared to a gas car. But if your apartment building has charging, your workplace offers free charging, or you have access to a nearby Level 2 charger, the math improves significantly.

How long does it take to break even on the upfront price difference?

Most owners break even within five to seven years through fuel and maintenance savings. If you use federal and state tax credits, the break-even point can be three to four years. High-mileage drivers break even faster; low-mileage drivers take longer.

Will my electric car lose value faster than a gas car?

Electric cars used to depreciate faster, but that trend is reversing as demand grows and battery technology improves. Today, most electric cars hold their value about as well as comparable gas cars over a five-year period. Used electric car prices have stabilized and are rising in many markets.

What happens if the battery degrades before I sell the car?

Most batteries retain 80 to 90 percent of their capacity after 10 years or 150,000 miles. A degraded battery still works; it just has less range. Most owners do not notice meaningful degradation within the first eight to ten years, and the manufacturer warranty covers defects during that time.
