At current U.S. energy prices, an efficient EV charged at home can cost roughly $5.69 per 100 miles to power, while a comparable 27-mpg gasoline SUV costs about $15.13 per 100 miles. Use public charging instead, and that same EV can jump to about $13.11 per 100 miles. The fuel-cost winner is usually the home-charged EV, but the full ownership winner can be an EV, a gas vehicle, or a hybrid once purchase price, depreciation, financing, insurance, charging equipment, and repair risk enter the bill.

The national numbers behind that comparison are unusually far apart in 2026. The latest weekly U.S. gasoline data puts regular at $4.085 per gallon for August 24. The latest residential electricity data puts June power at 18.34 cents per kWh. Public charging is a different market: AAA’s daily charging tracker lists a U.S. commercial/public average of 42.3 cents per kWh.

An EV-versus-gas comparison is really a comparison of energy efficiency, where the driver charges, miles driven, vehicle class, and ownership period. The useful unit is cost per 100 miles, followed by the annual energy bill and then the full ownership bill. Comparing only MPGe with MPG, or only electricity with gasoline, leaves out the expenses that can reverse the answer.

Article Highlights

• A 2026 Chevrolet Equinox EV FWD at current national residential electricity prices costs about $5.69 per 100 miles for energy. A 27-mpg gasoline Equinox costs about $15.13 (at $30 per hour, earning that amount would take about 30 minutes, before taxes) per 100 miles.
• At today’s public-charging average, the Equinox EV rises to about $13.11 per 100 miles, cutting its annual energy saving versus the gas Equinox from about $1,417 to just $302 at 15,000 miles.
• The energy break-even point for this Equinox comparison is about 48.8 cents per kWh. Above that, electricity costs more per mile than gasoline at $4.085 per gallon.
• ThePricer recalculation of AAA’s 2025 ownership categories using current energy prices finds the EV lowest in the sampled medium-SUV group, while the hybrid remains lowest in the sampled medium-sedan, compact-SUV, and pickup groups.
• Fuel savings do not automatically repay a higher purchase price. The base 2026 Equinox EV starts about $6,195 above the gasoline Equinox before destination, tax, dealer pricing, and options.
• An out-of-warranty EV battery replacement can cost $5,000 to $16,000, but battery failure requiring replacement has been rare in modern vehicles, so charging every EV owner for a future pack replacement distorts the comparison.

Home charging still wins the energy bill

A clean comparison is the front-wheel-drive 2026 Chevrolet Equinox EV against the front-wheel-drive gasoline Equinox. The EPA-rated Equinox EV figures are 31 kWh per 100 miles, 108 MPGe, and a $34,995 (about 6.7 months of full-time work at $30 per hour) starting MSRP. The gasoline Equinox rating is 27 mpg combined with a $28,800 starting MSRP.

2026 Equinox scenario	Energy price used	Cost per 100 miles	Cost at 15,000 miles
Equinox EV, home charging	18.34¢/kWh	$5.69	$853/year
Equinox EV, public charging	42.3¢/kWh	$13.11	$1,967/year
Equinox gasoline FWD	$4.085/gal	$15.13	$2,269/year

The home-charging arithmetic is simple: 31 kWh multiplied by $0.1834 equals about $5.69 for 100 miles. The gasoline Equinox needs about 3.70 gallons to cover the same 100 miles, and 3.70 multiplied by $4.085 comes to about $15.13.

There is an easy double-counting trap in EV math. Do not add another blanket charging-loss percentage to the EPA’s 31 kWh/100-mile figure. The EPA EV testing method says its MPGe values assume Level 2 AC charging and already account for losses through the charging cable, EVSE, and onboard charger.

At 15,000 miles per year, home charging saves about $1,417 in energy versus the gasoline Equinox. Public charging cuts that saving to roughly $302. Nothing about the vehicle changed. The place where the driver bought electricity changed.

The public-charging cliff

Public charging is where the simple “electricity is cheaper than gas” rule starts to fail. AAA’s current national public rate is 42.3 cents per kWh, more than twice the June residential average.

For the Equinox pair, the break-even electricity price is about 48.8 cents per kWh. The math takes the gasoline SUV’s $15.13 (about 30 minutes at $30 per hour) cost per 100 miles and divides it by the EV’s 31 kWh consumption. At that electricity rate, both vehicles cost the same to power for 100 miles.

The charging mix matters just as much. For this same Equinox EV at 15,000 miles, an owner who buys 20% of electricity publicly and 80% at home spends about $1,076 per year. A 50/50 split costs about $1,410. An 80% public-charging mix reaches about $1,744. The gasoline benchmark stays at roughly $2,269.

This is why apartment access, workplace charging, and a usable home circuit belong in the price comparison. A garage can be a financial advantage, not merely a convenience. The same home-versus-fast-charging split shows up in model-specific Tesla charging costs, where the electricity source can move the per-mile bill sharply.

Fuel break-even

The energy calculation answers which drivetrain costs less to move 100 miles. It does not answer which vehicle costs less to own for five years.

AAA’s 2025 ownership-cost comparison separates fuel, maintenance, depreciation, insurance, registration and taxes, and finance charges for selected EV, gasoline, and hybrid models. Its companion methodology and price assumptions used $3.151 per gallon gasoline and 16.7 cents per kWh electricity.

ThePricer ran a sensitivity test rather than pretending those 2025 energy prices are current. Every AAA non-energy line item stays unchanged. Only the fuel line is scaled to $4.085 gasoline and 18.34-cent electricity. The result is not an AAA 2026 forecast. It shows how the existing AAA ownership ledger reacts to today’s energy prices.

AAA sampled category	EV with current energy	Gas with current energy	Hybrid with current gas	Gas price where EV equals gas
Medium sedan	$13,764/year	$10,451/year	$9,805/year	$10.34/gal
Compact SUV	$11,264/year	$10,787/year	$10,740/year	$4.96/gal
Medium SUV	$12,795/year	$13,236/year	$13,338/year	$3.45/gal</>
Pickup	$16,873/year	$15,574/year	$15,345/year	$5.61/gal

The medium-SUV case shows how an oil-price shock can flip the full bill. AAA’s original sampled medium-SUV EV had $862 in annual electricity cost at 16.7 cents per kWh. Scaling that to 18.34 cents produces about $947. The sampled gas SUV’s $2,198 fuel line at $3.151 gas scales to about $2,850 at $4.085. Keeping AAA’s other costs fixed moves the EV to about $12,795 per year and the gas vehicle to about $13,236.

The medium sedan goes the other direction. AAA’s sampled electric sedans carried far higher depreciation than the gasoline set, so even today’s expensive gasoline does not close the gap. Under the same sensitivity test, gasoline would need to reach roughly $10.34 per gallon before the EV and gas totals meet.

The hybrid can beat both sides

The EV-versus-gas debate often leaves out the drivetrain that can spoil a simple two-sided answer. In this AAA sensitivity test, the hybrid is lowest in the sampled medium-sedan, compact-SUV, and pickup categories. The EV is lowest in the sampled medium-SUV category.

That does not mean hybrids are always cheapest. AAA used selected top-selling 2025 models, and its figures are category averages, not quotes for every vehicle on sale. It does show why a buyer comparing three actual models should not stop after calculating gas versus electricity.

A hybrid can avoid the home-charger setup, reduce gasoline consumption, and retain a familiar refueling pattern. Its price, depreciation, insurance, and financing can still beat both alternatives even when the EV has the lowest energy cost per mile.

The $6,195 purchase-price hurdle

Using the sourced starting prices above, the EV carries a $6,195 starting-price gap before destination, taxes, dealer pricing, options, financing, or any local incentive.

At the calculated $1,417 annual home-energy saving, fuel savings alone need about 4.4 years to equal that starting-price gap. If the driver relies entirely on today’s public-charging average and saves only about $302 per year, the same simple payback stretches to roughly 20.5 years.

The two base trims do not have identical equipment, and resale, maintenance, insurance, financing, and dealer discounts still move the full result. The payback math only shows why cheaper electricity does not instantly repay a higher purchase price.

One old comparison also needs to disappear from 2026 shopping math. The federal new and used clean-vehicle credits are not available for vehicles acquired after September 30, 2025. A current calculator that automatically subtracts $7,500 from a new EV purchase can produce a false answer before the first mile is driven.

The garage

Home charging is the cheapest energy case in much of the country, but getting there can cost money. Federal guidance says Level 2 charging equipment can run about $500 to $4,000 before installation and incentives, and homes that need electrical-service work can cost more. The home-charging cost guidance specifically tells buyers to check electrical capacity before installation.

A dedicated 240-volt circuit is a separate line item. Straightforward EV-focused installations often fall around $800 to $1,200, while difficult wire runs, panel work, or service upgrades can push higher, as shown in the existing 240V outlet installation costs.

The old federal charger-credit assumption also needs a date check. The residential Alternative Fuel Vehicle Refueling Property Credit covered qualifying property placed in service only through June 30, 2026, according to the current IRS charger-credit rules. A late-August 2026 installation should not automatically budget that federal credit.

Battery replacement is a risk

An EV battery can change an ownership calculation, but charging every EV owner for a full replacement is as misleading as ignoring the risk.

The Department of Energy’s battery-failure data cites a study of about 15,000 plug-in vehicles with battery replacement due to failure at 1.5% outside recalls across model years 2011 through 2023. For model years 2016 through 2023, the rate was well under 1%, with many failures likely covered by manufacturer warranty.

For an owner who does get an out-of-warranty failure, published battery replacement research puts many full-pack jobs around $5,000 to $16,000, depending on pack size and manufacturer. Treat that as a low-frequency repair scenario, not a normal maintenance expense.

ThePricer risk math makes the size easier to see. If a home-charged Equinox saves about $1,417 per year in energy and an unlucky owner later faces a hypothetical $12,000 battery bill, that repair equals about 8.5 years of those energy savings. A $16,000 pack equals about 11.3 years. That does not mean the battery will fail. It shows why warranty status matters so much in a used-EV purchase.

Electricity has its own price shocks

The current U.S. benchmarks do not support a simple claim that drought has erased the EV’s home-charging advantage nationwide. Gasoline is above $4 per gallon, while the national residential electricity benchmark remains far below the public-charging rate.

Drought still belongs in regions where hydropower matters. EIA’s latest power-sector outlook says U.S. hydropower generation was 9% higher year over year in the first half of 2026, but forecasts a 3% decline in the second half because of intensifying western drought. It also expects more natural-gas generation.

Drought, gas-fired generation, heat, grid spending, utility regulation, and time-of-use rates can all move the price at the wall. Gasoline is more directly exposed to crude oil and refining shocks. The recent gas-price jump after the Iran strikes shows how fast the pump price can move.

Three drivers 

Garage commuter: A driver covering 15,000 miles with 80% home charging and 20% public charging in the Equinox EV spends about $1,076 per year on electricity under the current national rates used here. That is about $1,194 less than the gasoline Equinox’s modeled fuel bill.

Apartment driver: The same EV using public charging for every mile spends about $1,967 per year. The energy advantage shrinks to about $302. A higher-priced local charging network can erase it.

Low-mileage buyer: At 6,000 miles per year, the home-charged Equinox EV saves only about $567 per year in energy versus the gasoline Equinox. If that driver paid the full $6,195 starting-price gap, energy savings alone would need about 10.9 years to match it.

When an EV saves the most money

An EV has the strongest cost case when:

• most charging happens at a low residential or workplace electricity rate
• annual mileage is high enough for energy savings to matter
• the EV’s purchase price is close to the gas or hybrid alternative
• insurance and depreciation on the exact model are competitive
• the home already has enough electrical capacity for charging

The cost case weakens when:

• the driver depends heavily on paid public fast charging
• the EV carries a large purchase-price premium
• the model has weak resale value
• home charging requires expensive panel or service work
• a used EV is outside battery warranty and battery health is uncertain

A gasoline car can still win where electricity is expensive, mileage is low, or the comparable EV carries a large fixed-cost penalty. A hybrid is especially hard to beat when the buyer cannot charge at home but still wants lower fuel use.

Answers to Common Questions

Is an EV cheaper to drive than a gas car in 2026?

Usually on energy if it is charged mostly at home. In the Equinox example, home electricity costs about $5.69 per 100 miles versus $15.13 for gasoline. Full ownership can still favor gas or hybrid models.

When does public EV charging cost more than gasoline?

It depends on vehicle efficiency and gas prices. For the 31-kWh/100-mile Equinox EV versus a 27-mpg gas Equinox at $4.085 gas, the break-even charging rate is about 48.8 cents per kWh.

Should an EV buyer budget for a battery replacement?

It is sensible to understand the out-of-warranty risk, but not to treat a full pack replacement as scheduled maintenance. Modern battery replacements due to failure have been rare in the DOE data cited above.

Is a hybrid cheaper than both EV and gas?

Sometimes. In ThePricer’s current-energy sensitivity test of AAA’s sampled categories, hybrids came out lowest for medium sedans, compact SUVs, and pickups, while the EV was lowest for medium SUVs.

What number should I calculate before buying?

Start with your actual electricity rate, expected public-charging share, the vehicle’s kWh/100 miles, the competing car’s MPG, annual mileage, insurance quote, purchase price, and expected ownership period. Those inputs tell you far more than a national EV-versus-gas average.
