Charging a Rivian R2 in Washington
What it actually costs to charge at home on Washington's average residential electricity rate.

Yearly home-charging cost
Based on the Rivian R2’s efficiency (3 mi/kWh) at Washington's average residential rate. For comparison, a 30-mpg gas car at $3.50/gallon runs about 12¢/mile.
Home vs. public fast charging
Costs below are for a 10%–80% charge — the usable fast-charge window, about 63 kWh of the Rivian R2’s 90 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Public fast charging

~$0.50/kWh (DC fast)
Charging the Rivian R2 on public DC fast chargers costs roughly 5.0× more than at home — about $25.20 extra per 10→80% charge. Most owners charge at home and only use fast charging on road trips, so your real average lands much closer to the home number.
Level 1 vs. Level 2: can your outlet keep up?
The cost per kWh is the same either way. What changes is how fast the Rivian R2 recovers range while parked at home.
Level 1 · standard outlet
~4 mi/hour
120V · no installation needed
~11 hours to recover 40 miles of driving. A 10-hour overnight plug-in adds about 36 miles.
Level 2 · 240V circuit
~29 mi/hour
240V · uses the Rivian R2’s 9.6 kW onboard charger
~1 hour to recover 40 miles. A 10-hour overnight plug-in adds up to 288 miles.
If your daily driving stays under ~36 miles, a regular outlet may be all the Rivian R2 needs. Drive more than that, and Level 2 — or a workplace charger — becomes the difference between an EV that fits your life and one that doesn’t.
Does a Level 2 install pay for itself?
A home Level 2 setup — 240V circuit plus charger — typically runs $800–$1,800 installed. If the alternative is relying on public fast chargers, home charging the Rivian R2 in Washington saves about $133.33/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 10 months — and every month after that is pure savings.
Winter in Washington
Washington averages about 3 months a year cold enough to cut EV efficiency — typically 15–25% in deep winter. Here’s what that does to the Rivian R2’s numbers at a 20% efficiency loss:
Cost per mile
~4.2¢vs. 3.3¢ in mild weather
Full-charge range
~216 mivs. ~270 mi
The cost bump is minor — a few dollars a month. The range cut matters more: if your daily driving is close to the Rivian R2’s limits, winter is when a marginal charging setup stops working.
Will a Rivian R2 actually work for your home in Washington?
Cost is one piece. The bigger question is whether your outlet and daily driving keep you covered without relying on public chargers. Answer 5 quick questions for a clear, personalized answer.
