Why this number

Charging a 2027 Rivian R2 costs about $17.89 for a full charge (~105 kWh) at the US average rate of 17¢/kWh — roughly $5.63 per 100 miles, or $675 a year at 12,000 miles. The R2 uses 33.1 kWh/100 mi on the EPA combined cycle. The R2’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Rivian R2 (EPA data for the 2027 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 33.1 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 R2 at about $5.63 per 100 miles — 5.63¢ a mile. That is comfortably better than average — 25th 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 R2 costs to charge at every rate

The same R2 costs $4.09 per 100 miles at Idaho’s 12.35¢ and $17.45 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the R2: EPA’s 33.1 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 R2’s 5.63¢ 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 R2’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the R2 really means

EPA combined range is about 318 miles. Multiplying that by the car’s efficiency gives roughly 105 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 R2 on a public fast charger

On a public fast charger at about 48¢/kWh the R2 costs $15.89 per 100 miles against $5.63 at home — 2.8× — or roughly $1,907 a year instead of $675 if it never sees a home outlet. Why a session costs more than the posted price for a R2 (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 R2’s $675 flat-rate figure.

The R2 in cold weather

A hard winter lifts the R2 from 33.1 to roughly 43.0 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $7.32 per 100 miles instead of $5.63 and an effective range nearer 245 miles than 318. The mechanics behind the R2’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the R2’s $675 annual figure above already averages the seasons.

Where the R2 sits against other EVs

Its nearest neighbors on efficiency are the Volvo EX30 (33.0 kWh/100 mi) and the Kia EV6 (33.2 kWh/100 mi). The R2 at 33.1 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 R2 is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $126 less than the R2.

Trims: does the R2 version you pick change the bill?

The EPA rates 2 configurations of the 2027 R2, from 32.2 to 34.1 kWh/100 mi. That is a narrow band — about $39 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 Rivian range

The R2 at 33.1 kWh/100 mi sits among 3 Rivian EVs tracked here, running from 33.1 (R2) to 45.0 (R1T). Also on this site: Rivian R1S , Rivian R1T .

The tax question for the R2, answered plainly

Nothing about the R2 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 R2: 33.1 kWh/100 mi ÷ 100 × 17¢ = $5.63 per 100 miles; 318 mi × 33.1 ÷ 100 = 105 kWh, × $0.17 = $17.89 per full charge; $5.63 × 12,000 ÷ 100 = $675 a year. The R2’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
