How Much You Really Save With an EV vs Gas (2026): Real Numbers by Mileage and Price

Two drivers, the same 13,500-mile year. One plugs in at home, one fills up at the pump. By December, the first has spent about $800 on energy and the second close to $1,900 on gasoline. Here is exactly where that $1,100 gap comes from — and the few situations where it shrinks to nothing.

By Petra Halvorsen, Energy & E-Mobility Cost Analyst · Published 30 June 2026 · Data current to Q2 2026


The honest version of "how much does an EV save you" starts with a refusal to give one number, because the real answer is a small equation with three inputs: how many miles you drive, what you pay for electricity, and what you pay for gasoline. Plug in the 2026 US averages and a clean figure falls out — a home-charging electric car costs roughly 5.9 cents per mile in energy against about 14.3 cents for a typical new gas car, a saving near $1,140 a year for the average 13,500-mile driver [S1][S10][S35]. Stretch that across five years and add the lower maintenance bill, and the gap grows to somewhere between $5,700 and $11,400 depending almost entirely on how much you drive.

But averages hide the cases that matter. A driver who can only use public fast chargers saves almost nothing. A Californian paying $5 at the pump saves far more than a Texan paying $3. And none of these running-cost numbers say anything about the EV's higher sticker price, which is a separate question this piece keeps deliberately separate. What follows is a calculator in prose: the per-mile arithmetic, the annual and five-year totals, the state-by-state spread, three real model match-ups, and the caveats that decide whether the saving is real for you.

The short answer: a home-charged EV saves the average US driver about $1,100 a year on fuel

At 2026 prices the typical saving is $1,100 to $1,400 a year in fuel for a driver who charges mostly at home and covers the national-average 13,500 miles [S1][S7][S35]. The number moves with the pump: against cheap $3.15 gasoline the fuel saving is closer to $770 a year, and against $5 California gas it climbs past $1,680. Maintenance adds a few hundred dollars more on top, because EVs have no oil changes, no exhaust system, no spark plugs, and use regenerative braking that spares the pads [S20][S21].

That is the figure most buyers actually want, and it is robust because it rests on government data, not manufacturer claims. The US Department of Energy's long-running comparison puts EV fuel costs about 60% below gasoline nationally, and AAA's 2025 "Your Driving Costs" study — which is not an EV advocate — found electricity for charging cost "less than half" of gasoline per mile [S13][S4][S6]. Where analysts disagree is on the size of the gap in any given week, not on its direction. Charging at home is cheaper than burning gasoline in every US state once you can plug in overnight [S33][S34].

How the numbers work: cost per mile is where EVs win

The entire advantage compresses into one comparison: about 5.9 cents per mile for a home-charged EV versus 14.3 cents for a 27 mpg gas car at $3.90 gasoline [S1][S10]. Everything else in this article is that single gap, multiplied by miles and years.

Here is the arithmetic, because a calculator you can't see inside is just a black box. A reasonably efficient EV uses about 0.33 kWh of electricity per mile measured at the wall — that is roughly 3.0 miles per kWh after accounting for the 8–9% of energy lost as heat during AC home charging, on an EPA-rated efficiency near 3.3 mi/kWh for a car like a Tesla Model 3 [S26][S37]. Multiply 0.33 kWh by the US average residential electricity price of 17.9 cents/kWh and you get 5.9 cents per mile [S1]. On the gas side, the EPA's real-world average for a model-year-2024 new vehicle is 27.2 mpg [S10]; divide a $3.90 gallon by 27.2 miles and you get 14.3 cents per mile [S35].

The DOE frames the same physics a second way, through what it calls the eGallon: the cost of the electricity needed to drive as far as a gas car goes on one gallon. Nationally that runs about $1.41, less than half the 2026 pump price — which is why the per-mile gap is so durable even when gasoline is cheap [S13][S16]. The underlying reason is efficiency: DOE's real-world data shows EVs are 2.6 to 4.8 times more efficient than internal-combustion cars at turning stored energy into forward motion, because a gasoline engine throws most of its fuel away as heat [S14].

Two honest adjustments belong here. First, the gas comparison gets worse for the combustion car if you compare against the on-road fleet average of roughly 25 mpg rather than a brand-new 27.2 mpg car, pushing gasoline to about 15.6 cents/mile. Second, the EV figure gets better on a dedicated overnight EV rate — many utilities offer time-of-use windows near 12 cents/kWh, dropping the EV to about 4.0 cents/mile [S33]. The point of stating the method out loud is that you can re-run it with your own electricity rate and your own car's mpg in thirty seconds.

Annual savings depend on three inputs you can actually measure

Run the per-mile numbers out to a full year of driving and the spread is wide: from about $535 for an EV on a cheap overnight rate to nearly $2,500 for a gas car in a $5-per-gallon state, all at the same 13,500 miles [S1][S33]. The chart below lays out every common scenario side by side.

Annual fuel/energy cost: EV vs gas at 13,500 miles/year (US, 2026) ($/year)

Our calculation from EIA electricity [S1], EPA efficiency [S10], and modeled charging/pump prices [S33][S35].

Read it from the bottom up and the story is clear. The three cheapest bars are all EVs charging at home; the three most expensive are gas cars or an EV forced onto public fast charging. The base case most buyers should anchor on is the second bar — an EV on the ordinary US residential rate at $797 a year — against the fifth bar, a $3.90 gas car at $1,936. That is the $1,140 annual fuel saving in visual form [S1][S35].

The chart also exposes the single biggest swing factor, which is not the car but the gasoline price. Move the gas bar from $3.15 to $5.00 and the gas driver's annual bill jumps by more than $900 while the EV bars don't move at all — electricity prices are far less volatile than oil. In 2026 that volatility was vivid: the national pump average ran near $3.15 when AAA built its study, climbed to $4.48 in May after Middle East supply scares, and sat around $3.90 by late June [S4][S35][S38]. Every dollar gasoline rises widens the EV's annual lead by roughly $135 for the average driver; electricity would have to nearly double before the EV lost its edge.

The mirror-image risk is on the chart too. The sixth bar — an EV charged only on public DC fast chargers at 45 cents/kWh — lands at $2,005 a year, essentially level with the $3.90 gas car. For the roughly one-in-six drivers without reliable home charging, the headline saving can collapse entirely, a point we return to below [S25].

Over five years, fuel plus maintenance savings run $5,700 to $11,400

Hold the car five years and the savings compound into real money: about $5,700 at 10,000 miles a year, $7,700 at 13,500 miles, and $11,400 at 20,000 miles a year, combining fuel and maintenance at $3.90 gasoline [S10][S19]. The more you drive, the more you save, because the EV banks a fixed advantage on every mile.

Five-year fuel + maintenance cost: EV vs gas, by annual mileage (2026) ($ over 5 years)
EV (home charging)Gas car10,000 mi/yr44501015013,500 mi/yr60081370320,000 mi/yr890020300
Our calculation; gas at $3.90/gal and 27.2 mpg, EV at home-average electricity, maintenance per Consumer Reports [S10][S19].

The maintenance half of that total deserves its own spotlight, because it is the part buyers most often forget. Consumer Reports' analysis of member-survey data — thousands of real vehicles, not a lab — found EVs cost about half as much to maintain and repair: roughly 3 cents per mile against 6 cents for a comparable gas car, and a lifetime total near $4,600 versus $9,200 [S19][S20][S21]. No oil changes, no transmission service, no timing belts, no exhaust or emissions repairs, and brake pads that last far longer thanks to regenerative braking. Over five years at 13,500 miles a year that 3-cent-per-mile gap alone is worth about $2,025.

Stack fuel and maintenance and the typical five-year saving lands near $7,700 for the average-mileage driver — squarely inside the $6,000–$10,000 lifetime range Consumer Reports reports across most EV models, and consistent with the ICCT's finding that EVs are cheaper to own than comparable gas cars for most US drivers covering 10,000–15,000 miles and holding five years or more [S19][S36]. Below is the same calculation in table form, so you can find your own mileage row.

Annual miles EV 5-yr (fuel + maint.) Gas 5-yr (fuel + maint.) 5-yr saving

Our calculation. EV at 0.33 kWh/mi and 17.9c/kWh home electricity; gas at 27.2 mpg and $3.90/gal; maintenance 3c/mi (EV) vs 6c/mi (gas) per Consumer Reports [S1][S10][S20]. Excludes purchase price, depreciation, insurance, financing and tax credits.

Public-only charging erases most of the advantage

The biggest way to lose the saving is to do all your charging in public: at a 45 cents/kWh DC-fast rate an EV costs about 14.9 cents per mile — essentially identical to a $3.90 gas car at 14.3 cents [S33][S34]. The entire EV fuel case rests on the assumption, true for most owners, that the great majority of charging happens cheaply at home.

That assumption is well supported. The IEA estimates 83% of US EV charging happens at home, and J.D. Power's 2026 Home Charging Study puts it even higher at 86%, with the average owner spending about $63 a month on home charging [S25][S23][S24]. Home is where the cheap electrons live, and it is also where convenience lives — you wake up "full" every morning without a detour.

But the minority who can't charge at home — apartment dwellers, street parkers — face very different math. Public DC fast charging in the US averaged roughly 45–50 cents/kWh across networks in early 2026, with non-member rates on some ultra-fast chargers reaching 68–85 cents/kWh in high-cost states [S33][S34]. A realistic 80% home / 20% public mix still lands around 7.7 cents/mile and $1,038 a year — clearly better than gasoline — but a true public-only pattern wipes the advantage out. This is the single most important question to settle before buying: where will this car actually charge? If the answer is "mostly a fast charger by the highway," the running-cost case is far weaker than the brochure implies [S18].

Two surcharges make public charging quietly worse than its headline per-kWh rate, and neither shows up in a simple calculator. The first is the session or connection fee some networks add on top of the energy price, which inflates the effective rate sharply on a small top-up. The second is the idle fee, billed by the minute once your car finishes charging but stays plugged in — a few dollars that can turn a cheap session expensive if you wander off to lunch. Stacked on a non-member ad-hoc rate, these fees mean a casual public charger can pay double what a home-charging owner pays for the same mile [S33]. The practical defense is a single network membership matched to your usual route, which typically pays for itself within a couple of charges and pulls the per-kWh rate back toward the home-versus-public midpoint.

There is also a seasonal wrinkle the annual averages smooth over: cold weather. EV efficiency falls in winter as the battery and cabin draw heat, so a car that sips 0.30 kWh/mile in mild conditions can climb above 0.40 kWh/mile in a hard freeze, raising the per-mile cost by a third for those months [S27]. Gasoline cars lose efficiency in the cold too — short trips, idling to warm up, winter fuel blends — so the gap between the two narrows less than the EV's raw number suggests, but a buyer in a northern state should budget a higher winter electricity bill and a slightly smaller seasonal saving.

Where you live changes the math more than which car you buy

The same EV that saves a Washington driver a fortune saves a Hawaii driver comparatively little, because residential electricity ranges from about 12 cents/kWh in Washington to roughly 41 cents in Hawaii — a more than threefold spread [S1][S33]. The eGallon chart below translates that into the metric that matters: what it costs in electricity to drive as far as one gallon of gas takes you.

eGallon: cost of electricity to drive as far as one gallon of gas, by state (2026) ($ per eGallon)
Washington (12c)1.09US average (17.9c)1.62Massachusetts (29.5c)2.67California (32c)2.9Hawaii (41c)3.72
Our calculation at 27.2 mpg-equivalent and 3.0 mi/kWh; state electricity rates per EIA and state surveys [S1][S33].

In Washington, that eGallon is $1.09 — you are effectively buying gasoline at a dollar a gallon. At the US average it is $1.62. But in Massachusetts it is $2.67, in California $2.90, and in Hawaii $3.72, closing in on the actual pump price in cheaper-gas states [S1][S33]. Crucially, the high-electricity states are usually also high-gasoline states — California's near-$5 pump price keeps the EV ahead even at 32 cents/kWh — so the EV still wins almost everywhere. But the size of the win compresses sharply in the Northeast and Hawaii, and expands hugely across the South, the Mountain West and the Pacific Northwest [S34].

There is a second geographic lever most calculators ignore: time-of-use rates. Utilities in California, Texas and much of the Mountain West offer dedicated overnight EV plans well below the residential average — often 8–14 cents/kWh in the small hours [S33]. A California EV owner paying 32 cents on the standard tariff but 12 cents on an overnight EV plan cuts their per-mile cost by nearly two-thirds, turning a mediocre state for EV savings into a strong one. The lesson is that which rate plan you choose can matter as much as which state you live in.

Real model match-ups: Model Y, Model 3, and the F-150 Lightning

Concrete cars make the abstract numbers real, and three popular match-ups show the pattern across a sedan, an SUV and a truck — fuel savings of roughly $960 a year (SUV) up to $3,500 a year (truck, high mileage), all favoring the EV [S28][S31].

Tesla Model Y vs Toyota RAV4. On energy alone the Model Y runs about 4 cents per mile against roughly 10.4 cents for a RAV4 Hybrid at current prices — a 61% per-mile advantage [S29]. At 15,000 miles a year that is about $600 in electricity versus $1,560 in gas, a $960 annual difference; in California's $6 gas, the RAV4 driver's bill climbs toward $2,250 and the gap widens further [S28][S29]. The RAV4 Hybrid is itself efficient, which makes the Model Y's lead a conservative illustration — against a non-hybrid gas crossover the gap is larger.

Tesla Model 3 vs Toyota Camry. Charged at home, a Model 3 comes out a little over a cent per mile cheaper than even a Camry Hybrid, and dramatically cheaper than the standard gas Camry. One worked example at 100 miles a day put the Model 3's home-charging cost at about $124 a month against roughly $371 in gasoline for the equivalent Camry — a $247 monthly, near-$3,000-a-year saving for that heavy-mileage driver [S30]. The same source flags the now-familiar caveat: lean on DC fast charging and the Model 3's effective cost per mile can roughly double.

Ford F-150 Lightning vs gas F-150. Trucks show the biggest absolute savings because they burn the most fuel. One owner documented running a 26,100-mile year in an F-150 Lightning for about $3,030 — home charging, road-trip fast charging and maintenance included — against an estimated $6,600 for the equivalent EcoBoost gas F-150, a $3,570 annual gap [S31]. The asterisk is towing: a Lightning's efficiency collapses to roughly 0.6–1.0 mi/kWh under heavy load, and if those towing miles run on DC fast chargers the EV truck's cost per mile can rival or exceed the gas truck's. For daily driving and light loads, though, the Lightning's running-cost lead is large [S32].

The honest caveat: running savings are not the whole sticker

These numbers are fuel and maintenance only — and on the full ownership picture, AAA found in 2025 that new EVs still cost more overall than comparable gas cars in three of four vehicle classes [S4][S6]. Ignoring that is how EV math gets a bad name.

The reason is straightforward: an EV's lower running costs are fighting a higher purchase price, steeper early depreciation, and often pricier insurance. AAA's composite annual ownership cost for a new vehicle was $11,577 in 2025, and across medium sedans, compact and medium SUVs and pickups, the all-electric versions came out costlier once depreciation, financing, insurance and fees were added in — precisely because cheap 2025 gasoline shrank the operating-cost advantage that has to offset all of that [S4][S5]. The EV saves on the operating line and loses on the ownership line; whether it wins overall depends on how big each is for your specific car, mileage and hold period.

Three factors tip that balance toward the EV. High mileage front-loads the fuel and maintenance savings, reaching break-even on the price premium sooner. A long hold lets five-plus years of running savings accumulate past the early depreciation hit. And incentives — where a federal or state credit still applies — can erase much of the sticker gap up front [S36]. The ICCT's modeling is blunt about the threshold: for most US drivers covering 10,000–15,000 miles and keeping the car five years or more, the EV is cheaper to own; for low-mileage drivers who trade every two years, it often is not [S36]. Run your own numbers against your own pattern before you treat the running-cost saving as a net saving.

How to capture the maximum savings

The levers are few and worth real money: the difference between a well-run EV and a badly-run one is easily $1,000 a year, and three habits capture most of it. None require hypermiling or spreadsheets.

First, charge at home, overnight, on a time-of-use plan. This is the single largest lever. Moving from the residential average (17.9 c/kWh) to a dedicated overnight EV rate near 12 c/kWh cuts the per-mile cost by a third, and in the highest-rate states by far more [S1][S33]. If you have a driveway and you're still on a flat tariff, you are leaving the easiest savings on the table.

Second, treat public DC fast charging as the exception, not the rule. It is the most expensive way to fuel an EV — two to four times the home rate — so reserve it for road trips and use cheaper Level 2 destination charging (hotels, workplaces, shopping centers) where you can [S33][S34]. A driver who quietly drifts to 40% public charging can halve their savings without noticing.

Third, match the comparison honestly. If you genuinely drive a lot and keep cars a long time, the EV's case is strong; if you barely drive and trade often, run the full ownership numbers including depreciation before committing [S4][S36]. The fuel saving is real and durable — but it is one line in a longer ledger, and the buyers who are happiest are the ones who looked at the whole page.

The bottom line for 2026 is the one the data has pointed to all along: a typical US driver who charges at home saves on the order of $1,100 a year on fuel and several hundred more on maintenance, building to roughly $7,700 over five years — more if they drive a lot or gas spikes, less if gas is cheap, and close to nothing if every charge happens at a highway fast charger [S1][S19][S35]. The car matters less than how — and where — you fuel it.


Common questions

How much does an EV actually save per year vs gas in 2026? For a typical US driver covering 13,500 miles and charging mostly at home, about $1,100–$1,400 a year in fuel at 2026 prices — roughly $800 if gas is cheap ($3.15) and up to $1,700 where gas is $5 [S1][S35]. Maintenance adds a few hundred dollars more [S20].

What about over five years? Fuel plus maintenance savings run roughly $5,700 at 10,000 miles a year, $7,700 at 13,500, and over $11,000 at 20,000 — assuming home charging and $3.90 gas [S10][S19]. Consumer Reports puts typical lifetime savings at $6,000–$10,000 [S19].

Does an EV still save money if gas is cheap? Yes, but less. At $3.15/gallon a 27 mpg gas car costs about 11.6 cents/mile versus 5.9 cents for a home-charged EV — still roughly half, for an annual saving near $770 [S1][S4]. The edge shrinks but doesn't vanish at low pump prices [S18].

What if I can't charge at home and rely on public fast charging? Most of the saving evaporates. At a 45 cents/kWh DC-fast rate an EV costs about 14.9 cents/mile — roughly the same as a $3.90 gas car — so a public-only driver may save little or nothing on energy [S33][S34]. The EV math depends on cheap home or workplace charging [S25].

Do these savings include the higher purchase price of the EV? No. These are running-cost savings only — fuel and maintenance. AAA's 2025 analysis found EVs still cost more overall once depreciation, insurance and financing are included, so weigh running savings against a higher sticker and faster early depreciation [S4][S6].

Which states are cheapest and most expensive for EV savings? The saving is largest where electricity is cheap and gas dear. Washington, the Mountain West and much of the South sit near 12–15 cents/kWh; California, New England and Hawaii run 29–41 cents/kWh, where a home eGallon costs $2.70–$3.70 and the gap to gasoline narrows [S1][S33].

Does higher mileage make an EV more worth it? Yes. Because the EV saves a fixed amount per mile — about 8 cents on fuel plus 3 cents on maintenance — the more you drive, the faster those savings accumulate, which is why high-mileage drivers reach break-even on the price premium soonest [S20][S36].

© 2026 ChargeCostLab. Independent EV running-cost analysis. Figures reflect data available to Q2 2026 and will change as electricity tariffs, gasoline prices and exchange rates move. This article is informational and not financial advice. Last reviewed 30 June 2026.

Methodology & sourcing

Scope. This article isolates the running-cost gap between a battery-electric car and a comparable gasoline car in the United States in 2026 — fuel/energy and maintenance — and deliberately separates that from purchase price, depreciation, insurance and financing, which are discussed but not folded into the headline savings. All figures are 2025–2026 and dated alongside each use.

Energy and fuel prices. Home electricity uses the US residential average of 17.9 cents/kWh from the EIA Electric Power Monthly (2026 year-to-date) [S1], cross-checked against the EIA Short-Term Energy Outlook range of 17.8–18.9 c/kWh for 2026 [S2]. A modeled overnight EV time-of-use rate of 12 c/kWh and a public DC-fast-charge rate of 45 c/kWh are used for scenario rows, sourced to state and network surveys [S33][S34]. Gasoline is modeled at three points — $3.15 (the AAA "Your Driving Costs" 2025 basis [S4]), $3.90 (the EIA 2026 annual forecast and late-June 2026 AAA national average [S2][S35][S38]), and $5.00 (California [S33]) — because the 2026 pump price swung between roughly $3.15 and $4.48 during the year [S35].

Vehicle efficiency. The gas car is held to the EPA real-world new-vehicle average of 27.2 mpg (model year 2024) [S10]; a 25 mpg on-road-fleet figure is shown as a sensitivity. The EV is modeled at 0.33 kWh per mile delivered from the wall — equivalent to about 3.0 miles/kWh after roughly 9% AC charging losses on an EPA-rated efficiency near 3.3 mi/kWh [S26][S37].

Mileage. The base case is 13,500 miles/year (FHWA per-driver average, corroborated by Insurify) [S7][S9]; 10,000 and 20,000 mi/year bracket the range, and AAA's 15,000-mile basis is cited where its figures are quoted [S4].

Maintenance. Per-mile maintenance of 3 cents (EV) versus 6 cents (gas) and lifetime totals of $4,600 versus $9,200 come from Consumer Reports member-survey analysis [S19][S20][S21]. Every figure labeled "our calculation" is reproducible from the inputs above; every externally reported figure carries a source number.
