Why this number

Charging a 2027 Volvo EX90 costs about $19.21 for a full charge (~113 kWh) at the US average rate of 17¢/kWh — roughly $6.43 per 100 miles, or $771 a year at 12,000 miles. The EX90 uses 37.8 kWh/100 mi on the EPA combined cycle. The EX90’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Volvo EX90 (EPA data for the 2027 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 37.8 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 EX90 at about $6.43 per 100 miles — 6.43¢ a mile. That lands mid-pack: 46th of the 67 current models tracked here. Nothing about the running cost of the EX90 will surprise you in either direction, which for a SUV at 37.8 kWh/100 mi is a reasonable outcome.

What an EX90 costs to charge at every rate

The same EX90 costs $4.67 per 100 miles at Idaho’s 12.35¢ and $19.93 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the EX90: EPA’s 37.8 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 EX90’s 6.43¢ 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 EX90’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the EX90 really means

EPA combined range is about 299 miles. Multiplying that by the car’s efficiency gives roughly 113 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 EX90 on a public fast charger

On a public fast charger at about 48¢/kWh the EX90 costs $18.14 per 100 miles against $6.43 at home — 2.8× — or roughly $2,177 a year instead of $771 if it never sees a home outlet. Why a session costs more than the posted price for a EX90 (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 EX90’s $771 flat-rate figure.

The EX90 in cold weather

A hard winter lifts the EX90 from 37.8 to roughly 49.1 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $8.35 per 100 miles instead of $6.43 and an effective range nearer 230 miles than 299. The mechanics behind the EX90’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the EX90’s $771 annual figure above already averages the seasons.

Where the EX90 sits against other EVs

Its nearest neighbors on efficiency are the Jeep Wagoneer S (37.7 kWh/100 mi) and the Hyundai Ioniq 6 (37.9 kWh/100 mi). The EX90 at 37.8 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. And if a SUV like the EX90 is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $222 less than the EX90.

Trims: does the EX90 version you pick change the bill?

The EPA rates 5 configurations of the 2027 EX90, from 36.8 to 39.0 kWh/100 mi. That is a narrow band — about $45 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.

How it compares inside the Volvo range

The EX90 at 37.8 kWh/100 mi sits among 3 Volvo EVs tracked here, running from 33.0 (EX30) to 37.8 (EX90). Also on this site: Volvo EX30 , Volvo EX40 .

The tax question for the EX90, answered plainly

Nothing about the EX90 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 EX90: 37.8 kWh/100 mi ÷ 100 × 17¢ = $6.43 per 100 miles; 299 mi × 37.8 ÷ 100 = 113 kWh, × $0.17 = $19.21 per full charge; $6.43 × 12,000 ÷ 100 = $771 a year. The EX90’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
