Why this number

Charging a 2027 Hyundai Ioniq 5 costs about $15.11 for a full charge (~89 kWh) at the US average rate of 17¢/kWh — roughly $5.47 per 100 miles, or $657 a year at 12,000 miles. The Ioniq 5 uses 32.2 kWh/100 mi on the EPA combined cycle. The Ioniq 5’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Hyundai Ioniq 5 (EPA data for the 2027 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 32.2 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 Ioniq 5 at about $5.47 per 100 miles — 5.47¢ a mile. That is comfortably better than average — 20th most efficient of the 67 current models tracked here — and puts running costs in the range most buyers hope for when they switch.

What an Ioniq 5 costs to charge at every rate

The same Ioniq 5 costs $3.98 per 100 miles at Idaho’s 12.35¢ and $16.98 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the Ioniq 5: EPA’s 32.2 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 Ioniq 5’s 5.47¢ 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 Ioniq 5’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the Ioniq 5 really means

EPA range across the lineup runs 245–318 miles, averaging 276. Multiplying that by the car’s efficiency gives roughly 89 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 Ioniq 5 on a public fast charger

On a public fast charger at about 48¢/kWh the Ioniq 5 costs $15.46 per 100 miles against $5.47 at home — 2.8× — or roughly $1,855 a year instead of $657 if it never sees a home outlet. Why a session costs more than the posted price for a Ioniq 5 (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 Ioniq 5’s $657 flat-rate figure.

The Ioniq 5 in cold weather

A hard winter lifts the Ioniq 5 from 32.2 to roughly 41.9 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $7.12 per 100 miles instead of $5.47 and an effective range nearer 212 miles than 276. The mechanics behind the Ioniq 5’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the Ioniq 5’s $657 annual figure above already averages the seasons.

Where the Ioniq 5 sits against other EVs

Its nearest neighbors on efficiency are the BMW iX3 (31.7 kWh/100 mi) and the Chevrolet Equinox EV (32.6 kWh/100 mi). The Ioniq 5 at 32.2 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 Ioniq 5 is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $108 less than the Ioniq 5.

Trims: does the Ioniq 5 version you pick change the bill?

The EPA rates 5 configurations of the 2027 Ioniq 5, and they are not close: 29.0 kWh/100 mi for the most efficient, 35.8 for the least, a 23% spread. At 12,000 miles that is about $139 a year between the cheapest and most expensive version of the same Ioniq 5. Bigger wheels, all-wheel drive and performance tunes are usually what separates them — worth knowing before you tick the options box.

How it compares inside the Hyundai range

The Ioniq 5 at 32.2 kWh/100 mi sits among 4 Hyundai EVs tracked here, running from 29.5 (Kona) to 38.3 (Ioniq 9). Also on this site: Hyundai Kona , Hyundai Ioniq 6 , Hyundai Ioniq 9 .

The tax question for the Ioniq 5, answered plainly

Nothing about the Ioniq 5 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 Ioniq 5: 32.2 kWh/100 mi ÷ 100 × 17¢ = $5.47 per 100 miles; 276 mi × 32.2 ÷ 100 = 89 kWh, × $0.17 = $15.11 per full charge; $5.47 × 12,000 ÷ 100 = $657 a year. The Ioniq 5’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
