Why this number
The Kia EV9 (EPA data for the 2026 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 40.0 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 EV9 at about $6.80 per 100 miles — 6.80¢ a mile. That is on the heavy side — 56th of 67, where 67 is the least efficient — which is typical for a SUV 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 EV9 costs to charge at every rate
The same EV9 costs $4.94 per 100 miles at Idaho’s 12.35¢ and $21.09 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:
| Electricity rate | Per 100 miles | Full charge (~109 kWh) | Per year at 12,000 miles |
|---|---|---|---|
| 12¢/kWh | $4.80 | $13.06 | $576 |
| 15¢/kWh | $6.00 | $16.32 | $720 |
| 17¢/kWh (US avg) | $6.80 | $18.50 | $816 |
| 20¢/kWh | $8.00 | $21.76 | $960 |
| 25¢/kWh | $10.00 | $27.20 | $1,200 |
| 30¢/kWh | $12.00 | $32.64 | $1,440 |
| 35¢/kWh | $14.00 | $38.08 | $1,680 |
| 45¢/kWh | $18.00 | $48.96 | $2,160 |
Wall-side for the EV9: EPA’s 40.0 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 EV9’s 6.80¢ 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 EV9’s math in full — both formulas, and the electricity rate at which the advantage disappears.
Range: what a “full charge” of the EV9 really means
EPA range across the lineup runs 230–305 miles, averaging 272. Multiplying that by the car’s efficiency gives roughly 109 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 EV9 on a public fast charger
On a public fast charger at about 48¢/kWh the EV9 costs $19.20 per 100 miles against $6.80 at home — 2.8× — or roughly $2,304 a year instead of $816 if it never sees a home outlet. Why a session costs more than the posted price for a EV9 (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 EV9’s $816 flat-rate figure.
The EV9 in cold weather
A hard winter lifts the EV9 from 40.0 to roughly 52.0 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $8.84 per 100 miles instead of $6.80 and an effective range nearer 209 miles than 272. The mechanics behind the EV9’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the EV9’s $816 annual figure above already averages the seasons.
Where the EV9 sits against other EVs
Its nearest neighbors on efficiency are the Porsche Taycan (39.9 kWh/100 mi) and the Volkswagen ID. Buzz (41.4 kWh/100 mi). The EV9 at 40.0 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 EV9 is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $267 less than the EV9.
Trims: does the EV9 version you pick change the bill?
The EPA rates 5 configurations of the 2026 EV9, and they are not close: 38.0 kWh/100 mi for the most efficient, 43.0 for the least, a 13% spread. At 12,000 miles that is about $102 a year between the cheapest and most expensive version of the same EV9. Bigger wheels, all-wheel drive and performance tunes are usually what separates them — worth knowing before you tick the options box.

The tax question for the EV9, answered plainly
Nothing about the EV9 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 much does it cost to fully charge a Kia EV9?
About $18.50 at the US average residential rate of 17¢/kWh. Refilling 272 miles of EPA range draws roughly 109 kWh from the wall — the EPA figure is measured at the outlet, so charger and cable losses are already in it. At 12¢/kWh that is $13.06; at 45¢/kWh it is $48.96.
What does an EV9 cost per mile in electricity?
About 6.80¢ per mile for the EV9 at 17¢/kWh, measured at the wall. For the EV9 that is the number to set against gasoline: a 30-mpg car at $4.07 a gallon (EIA weekly, Aug 31, 2026) costs about 13.6¢ a mile.
Is it cheaper to charge the EV9 at home or at a public fast charger?
Home, for the EV9: about $6.80 per 100 miles at 17¢/kWh against roughly $19.20 on a 48¢ fast charger — 2.8 times as much, before idle fees and per-minute billing on some networks.
Does the EV9 qualify for a federal EV tax credit in 2026?
No — the EV9, like every EV bought after September 30, 2025, gets $0 federal purchase credit (§30D and §25E ended); the charger credit (§30C) ended June 30, 2026. State and utility EV programs are unaffected.
How we calculated this
Worked for the EV9: 40.0 kWh/100 mi ÷ 100 × 17¢ = $6.80 per 100 miles; 272 mi × 40.0 ÷ 100 = 109 kWh, × $0.17 = $18.50 per full charge; $6.80 × 12,000 ÷ 100 = $816 a year. The EV9’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628.
