Why this number

Charging a 2026 Toyota bZ costs about $13.33 for a full charge (~78 kWh) at the US average rate of 17¢/kWh — roughly $4.73 per 100 miles, or $567 a year at 12,000 miles. The bZ uses 27.8 kWh/100 mi on the EPA combined cycle. The bZ’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Toyota bZ (EPA data for the 2026 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 27.8 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 bZ at about $4.73 per 100 miles — 4.73¢ a mile. That puts it among the most efficient EVs on sale: 4 out of the 67 current models tracked here, ordered from least to most energy used. Efficiency at this level is what makes an EV genuinely cheap to run rather than merely cheaper than gasoline.

What a bZ costs to charge at every rate

The same bZ costs $3.43 per 100 miles at Idaho’s 12.35¢ and $14.66 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the bZ: EPA’s 27.8 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 bZ’s 4.73¢ 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 bZ’s math in full — both formulas, and the electricity rate at which the advantage disappears.

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

EPA range across the lineup runs 236–314 miles, averaging 282. Multiplying that by the car’s efficiency gives roughly 78 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 bZ on a public fast charger

On a public fast charger at about 48¢/kWh the bZ costs $13.34 per 100 miles against $4.73 at home — 2.8× — or roughly $1,601 a year instead of $567 if it never sees a home outlet. Why a session costs more than the posted price for a bZ (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 bZ’s $567 flat-rate figure.

The bZ in cold weather

A hard winter lifts the bZ from 27.8 to roughly 36.1 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $6.14 per 100 miles instead of $4.73 and an effective range nearer 217 miles than 282. The mechanics behind the bZ’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the bZ’s $567 annual figure above already averages the seasons.

Where the bZ sits against other EVs

Its nearest neighbors on efficiency are the Lucid Air (27.3 kWh/100 mi) and the Chevrolet Bolt EV (28.2 kWh/100 mi). The bZ at 27.8 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.

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

The EPA rates 8 configurations of the 2026 bZ, and they are not close: 25.5 kWh/100 mi for the most efficient, 30.6 for the least, a 20% spread. At 12,000 miles that is about $104 a year between the cheapest and most expensive version of the same bZ. 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 bZ at 27.8 kWh/100 mi sits among 3 Toyota EVs tracked here, running from 27.8 (bZ) to 30.7 (bZ4X). Also on this site: Toyota C-HR , Toyota bZ4X .

The tax question for the bZ, answered plainly

Nothing about the bZ 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 bZ: 27.8 kWh/100 mi ÷ 100 × 17¢ = $4.73 per 100 miles; 282 mi × 27.8 ÷ 100 = 78 kWh, × $0.17 = $13.33 per full charge; $4.73 × 12,000 ÷ 100 = $567 a year. The bZ’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
