5.2¢ vs 11.1¢: EV Electricity Cost per Mile Versus Gasoline in 2025

The operating-cost debate for electric vehicles often collapses into slogans: electricity is “cheap,” gasoline is “expensive,” or the reverse after a bad summer at the pump. Those slogans hide the only comparison that travels cleanly across vehicles and years — cents per mile. Take the Energy Information Administration’s calendar-year 2025 residential electricity average of 17.30 cents per kilowatt-hour, pair it with a midsize battery-electric vehicle that uses about 0.30 kWh per mile at the wall, and home charging costs roughly 5.2¢ per mile. Take EIA’s 2025 regular gasoline average of $3.097 per gallon, pair it with a 28 mpg gasoline car, and the same mile costs about 11.1¢. Gasoline is still a little more than twice as expensive per mile at those national anchors — even after three consecutive years of falling nominal pump prices.

That arithmetic is deliberately narrow. It ignores purchase price, insurance, tires, maintenance, and the time cost of charging. It also treats residential average revenue per kWh as a stand-in for what a household actually pays on an EV tariff, and it assumes Level-2 home charging rather than public DC fast charging. Those caveats matter. They do not erase the headline: on a pure fuel-and-electrons basis, the typical EV still undercuts the typical ICE car by about six cents a mile, or roughly $700 a year at 12,000 miles.

The interactive dashboard above holds efficiency fixed where useful, then lets you move residential power, gasoline, kWh/mi, and mpg. The national dual-line panel tracks how the gap evolved from 2016 through 2025. The sensitivity heatmap shows how quickly a high power rate or a thirsty EV can erase the advantage. The PADD scatter puts regional gasoline prints next to electricity proxies. The break-even curve asks a sharper question: how many miles per gallon would a gasoline car need to match the EV’s electricity cost per mile?

How cents per mile is built

Two formulas do almost all the work.

EV electricity cost per mile = residential cents per kWh × kilowatt-hours per mile.

Gasoline cost per mile = (dollars per gallon × 100) ÷ miles per gallon.

EIA’s residential series is average revenue per kWh sold to residential customers, including taxes — a national (or state) revenue/sales proxy, not a quoted residential tariff schedule. That is the right public series for a desk comparison, and it is also why a household on a time-of-use or EV-specific rate can beat or miss the national print. Gasoline prices are annual averages of EIA’s weekly retail regular-grade survey, all formulations, including taxes.

Efficiency is the other half of the story. The Department of Energy’s Fact of the Week #1373 (December 2024) notes that model-year 2024 EVs span roughly 1.49 to 4.17 miles per kWh on the EPA combined cycle — about 0.67 to 0.24 kWh per mile. Gasoline vehicles, including traditional hybrids, span roughly 9 to 57 mpg. A “typical” midsize BEV near 3.3 mi/kWh (0.30 kWh/mi) and a “typical” midsize ICE near 28 mpg are mid-pack anchors, not claims about every driveway.

MPGe — miles per gallon equivalent — is useful for energy-content comparisons because EPA treats 33.7 kWh as the energy in one gallon of gasoline. It is not a price comparison. A 100 MPGe sticker does not mean the EV costs one-hundredth of a gallon of gasoline to drive a mile; it means the vehicle travels 100 miles on 33.7 kWh of electricity. Cents per mile converts that energy use into what households actually pay.

The 2025 national snapshot

Calendar 2025 is a useful stress test because the two price series moved in opposite directions for the third straight year on gasoline. EIA reports that regular gasoline averaged about $3.10 per gallon in 2025, down roughly 21 cents from 2024 and well below the 2022 spike near $3.95. Residential electricity, meanwhile, continued its climb: 12.55¢/kWh in 2016, 15.04¢ in 2022, 16.48¢ in 2024, and 17.30¢ in 2025.

Hold efficiency fixed at 0.30 kWh/mi and 28 mpg and the history is blunt:

The EV line drifts upward with power prices. The gasoline line spikes in 2022, then retreats. The ratio compresses from more than 3× at the 2022 peak toward roughly 2.1× in 2025 — still a clear electricity advantage at these efficiencies, but a narrower one than the post-invasion gasoline spike suggested.

At 12,000 annual miles, the 2025 national pair is about $623 of residential electricity versus $1,327 of gasoline, a gap near $704. Change annual miles and the dollar gap scales linearly; the cents-per-mile gap does not.

Efficiency decides the margin more than the slogan

National averages hide the vehicle you actually own. An efficient EV near 4.2 mi/kWh (0.24 kWh/mi) at 17.30¢/kWh costs about 4.2¢/mi. A large or truck-like EV near 2.4 mi/kWh (0.42 kWh/mi) costs about 7.3¢/mi. On the gasoline side, a 22 mpg crossover at $3.10/gal costs about 14.1¢/mi; a strong hybrid at 45 mpg costs about 6.9¢/mi.

That last pairing is the uncomfortable one for EV advocates who argue from national averages alone: a thrifty hybrid can approach, and in some power markets beat, a thirsty EV on fuel-and-electrons cost. It does not overturn the midsize-to-midsize comparison. It does mean the honest sentence is conditional: at typical midsize efficiencies and national 2025 prices, electricity still wins; at the extremes of the DOE/EPA ranges, the winner is a local calculation.

The break-even mpg question makes the same point without picking a rival vehicle. At 17.30¢/kWh and 0.30 kWh/mi, EV cost is 5.19¢/mi. The gasoline mpg that matches that cost is:

mpg* = ($/gal × 100) ÷ 5.19 ≈ 59.7 mpg at $3.10/gal.

Very few non-hybrid gasoline cars live there. Many hybrids do. Plug-in hybrids complicate the picture further because their gasoline and electricity shares depend on how often the battery is charged — a behavioral variable this piece does not pretend to settle.

Where you live still moves the decimal

EIA’s PADD regular gasoline averages for 2025 stretch from about $2.68 on the Gulf Coast to about $4.09 on the West Coast. Residential electricity is even more geographically uneven: New England and parts of the Pacific sit far above the national 17.30¢ print, while parts of the interior South and Mountain West sit below it.

Pairing PADD gasoline with census-division electricity proxies (derived, not a perfect geographic match) shows the operating-cost map is not a single national story:

Two lessons jump out. First, cheap gasoline does not automatically erase the EV advantage if electricity is also relatively cheap — the Gulf pairing still shows gasoline roughly 2.2× electricity per mile at our fixed efficiencies. Second, expensive electricity can shrink the advantage dramatically even when gasoline is only average: the New England proxy compresses the ratio toward 1.25×. West Coast drivers face high numbers on both sides; the EV still wins on this narrow metric, but absolute cents per mile are elevated for everyone.

Public DC fast charging sits outside this map. Retail DCFC prices often run well above residential averages on a per-kWh basis, and session fees can dominate short charges. Households that rarely charge at home will not experience the 5.2¢ national headline.

What the dashboard is for

The interactive panels are built to keep the comparison honest under user assumptions rather than to crown a permanent winner.

• National trend holds 0.30 kWh/mi and 28 mpg fixed so price history is visible without confounding efficiency mix shifts.
• EV sensitivity is a heatmap of residential ¢/kWh against kWh/mithe two levers that set electricity cents per mile.
• PADD regions scatter EV versus gasoline cents per mile under the same efficiency anchors.
• Break-even mpg redraws the gasoline mpg required to match your live electricity cost as you move the power and efficiency sliders.

Use the scenario presets for a quick jump to national 2025, an efficient EV, a large EV versus hybrid ICE, New England-high power, Gulf cheap gas, or West Coast prices. Then nudge the sliders. If your utility bill shows 14¢/kWh off-peak and your car’s trip computer says 0.28 kWh/mi, the live readout is closer to your driveway than any national slogan.

Caveats and what this piece is not

Tariffs vs averages. EIA residential cents per kWh are average revenue per unit sold. Inclining-block rates, fixed customer charges, demand charges, and EV time-of-use discounts all change the marginal cost of the next charging kWh.

Charging path. Home Level-2 is the default. Workplace charging, condo access limits, and public DCFC can raise or lower effective ¢/kWh.

Vehicle class. Comparing a compact EV to a three-row gasoline SUV is not the same analysis as midsize-to-midsize. Weight, aerodynamics, and four-wheel-drive packages move both kWh/mi and mpg.

Total cost of ownership. Fuel-and-electrons is not TCO. Depreciation, insurance, maintenance, tires, and incentives can dominate for some buyers and some model years.

Taxes and externalities. Both series include retail taxes as EIA measures them. Neither embeds carbon prices, congestion, or local air-quality damages.

Geography mismatch. PADD gasoline districts and electricity census divisions do not share identical borders. Regional rows are illustrative pairings, marked derived on the electricity side.

Vintage. Figures track published annual EIA prints through 2025 and DOE/EPA MY2024 efficiency ranges. Weekly gasoline and monthly electricity will continue to move.

Bottom line

At EIA’s 2025 national residential electricity and regular gasoline averages, a typical EV at 0.30 kWh/mi costs about 5.2¢ per mile to charge at home, while a typical gasoline car at 28 mpg costs about 11.1¢ per mile to fuel. That is still roughly a 2.1× gasoline premium on a cents-per-mile basis — narrower than the 2022 spike, wider than a New England-high-power pairing, and contingent on efficiency. The right operating-cost question is not whether electricity is “cheap.” It is which price print and which efficiency you bring to the mile.
