Why this number

Charging a 2025 Toyota bZ4X costs about $12.11 for a full charge (~71 kWh) at the US average rate of 17¢/kWh — roughly $5.22 per 100 miles, or $626 a year at 12,000 miles. The bZ4X uses 30.7 kWh/100 mi on the EPA combined cycle. The bZ4X’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Toyota bZ4X (EPA data for the 2025 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 30.7 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 bZ4X at about $5.22 per 100 miles — 5.22¢ a mile. That is comfortably better than average — 14th most efficient of the 67 current models tracked here — and puts running costs in the range most buyers hope for when they switch.

What a bZ4X costs to charge at every rate

The same bZ4X costs $3.79 per 100 miles at Idaho’s 12.35¢ and $16.19 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the bZ4X: EPA’s 30.7 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 bZ4X’s 5.22¢ 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 bZ4X’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the bZ4X really means

EPA combined range is about 232 miles. Multiplying that by the car’s efficiency gives roughly 71 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. That is a modest range by 2026 standards, which matters less for cost than for how often you plan around charging on long trips.

The bZ4X on a public fast charger

On a public fast charger at about 48¢/kWh the bZ4X costs $14.74 per 100 miles against $5.22 at home — 2.8× — or roughly $1,768 a year instead of $626 if it never sees a home outlet. Why a session costs more than the posted price for a bZ4X (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 bZ4X’s $626 flat-rate figure.

The bZ4X in cold weather

A hard winter lifts the bZ4X from 30.7 to roughly 39.9 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $6.78 per 100 miles instead of $5.22 and an effective range nearer 178 miles than 232. The mechanics behind the bZ4X’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the bZ4X’s $626 annual figure above already averages the seasons.

Where the bZ4X sits against other EVs

Its nearest neighbors on efficiency are the Nissan Leaf (30.2 kWh/100 mi) and the Kia EV3 (31.0 kWh/100 mi). The bZ4X at 30.7 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 bZ4X is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $78 less than the bZ4X.

Trims: does the bZ4X version you pick change the bill?

The EPA rates 5 configurations of the 2025 bZ4X, and they are not close: 28.3 kWh/100 mi for the most efficient, 32.0 for the least, a 13% spread. At 12,000 miles that is about $75 a year between the cheapest and most expensive version of the same bZ4X. 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 Toyota range

The bZ4X at 30.7 kWh/100 mi sits among 3 Toyota EVs tracked here, running from 27.8 (bZ) to 30.7 (bZ4X). Also on this site: Toyota bZ , Toyota C-HR .

The tax question for the bZ4X, answered plainly

Nothing about the bZ4X 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 bZ4X: 30.7 kWh/100 mi ÷ 100 × 17¢ = $5.22 per 100 miles; 232 mi × 30.7 ÷ 100 = 71 kWh, × $0.17 = $12.11 per full charge; $5.22 × 12,000 ÷ 100 = $626 a year. The bZ4X’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
