Why this number

Charging a 2027 Mercedes-Benz EQS costs about $22.69 for a full charge (~133 kWh) at the US average rate of 17¢/kWh — roughly $7.23 per 100 miles, or $867 a year at 12,000 miles. The EQS uses 42.5 kWh/100 mi on the EPA combined cycle. The EQS’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Mercedes-Benz EQS (EPA data for the 2027 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 42.5 kWh per 100 miles on the EPA combined cycle — the wall-outlet figure, so charging losses are already counted (look up your exact trim at fueleconomy.gov ). At the US average residential rate of 17¢/kWh that puts the EQS at about $7.23 per 100 miles — 7.23¢ a mile. That is on the heavy side — 59th of 67, where 67 is the least efficient — which is typical for a sedan of this weight. It still costs far less per mile than gasoline, but it is not where EV running costs are at their best.

What an EQS costs to charge at every rate

The same EQS costs $5.25 per 100 miles at Idaho’s 12.35¢ and $22.41 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the EQS: EPA’s 42.5 kWh/100 mi is measured at the outlet, charger losses included; quick-fill your state above for your own figure.

That per-mile figure is the one to hold against gasoline: at 17¢/kWh the EQS’s 7.23¢ a mile compares with about 13.6¢ for a 30-mpg gas car at $4.07 a gallon (EIA weekly, Aug 31, 2026). The EV vs gas cost guide works the EQS’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the EQS really means

EPA combined range is about 314 miles. Multiplying that by the car’s efficiency gives roughly 133 kWh to refill a full range from empty, which is the honest way to think about a ‘full charge’ — battery capacity figures include a buffer you never actually use.

The EQS on a public fast charger

On a public fast charger at about 48¢/kWh the EQS costs $20.40 per 100 miles against $7.23 at home — 2.8× — or roughly $2,448 a year instead of $867 if it never sees a home outlet. Why a session costs more than the posted price for a EQS (10–80% charging curve, idle fees, per-minute billing) is explained once on the cost-to-charge hub ; the EV time-of-use calculator nets an overnight rate against the EQS’s $867 flat-rate figure.

The EQS in cold weather

A hard winter lifts the EQS from 42.5 to roughly 55.2 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $9.39 per 100 miles instead of $7.23 and an effective range nearer 242 miles than 314. The mechanics behind the EQS’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the EQS’s $867 annual figure above already averages the seasons.

Where the EQS sits against other EVs

Its nearest neighbors on efficiency are the Dodge Charger Daytona (42.4 kWh/100 mi) and the Tesla Cybertruck (43.1 kWh/100 mi). The EQS at 42.5 kWh/100 mi sits against a set that runs from the Tesla Model Y at 26.9 kWh/100 mi, and the least efficient is the GMC Hummer EV at 67.8 — a spread that changes annual charging cost by $834 a year at 17¢/kWh and 12,000 miles.

Trims: does the EQS version you pick change the bill?

The EPA rates 2 configurations of the 2027 EQS, from 42.0 to 43.0 kWh/100 mi. That is a narrow band — about $20 a year between the best and worst at 12,000 miles — so pick the trim you want and don’t agonise over the running cost.

The tax question for the EQS, answered plainly

Nothing about the EQS changes that: the rules are the same for every EV, and the full 2026 position — §30D, §25E, the ended §30C charger credit, state programs — is in the energy tax credit guide and on the cost-to-charge hub .

Frequently asked questions

How we calculated this

Worked for the EQS: 42.5 kWh/100 mi ÷ 100 × 17¢ = $7.23 per 100 miles; 314 mi × 42.5 ÷ 100 = 133 kWh, × $0.17 = $22.69 per full charge; $7.23 × 12,000 ÷ 100 = $867 a year. The EQS’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
