2026 Rivian R1T All-Terrain Dual Large (20in): home charging cost in Oregon
At Oregon's residential electricity rate of 15.31¢/kWh, a 2026 Rivian R1T All-Terrain Dual Large (20in) (rated 44.4 kWh per 100 miles by the EPA) costs $6.79 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 57.6% less than gas per mile, here specifically.
Annual cost, at 15 thousands miles a year
Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T All-Terrain Dual Large (20in) charged at home in Oregon costs about $1,019/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,384 a year.
Filling up the 2026 Rivian R1T All-Terrain Dual Large (20in), in dollars

Where this ranks
This combination ranks 12,442 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T All-Terrain Dual Large (20in) alone ranks 346 of 400 models for efficiency; Oregon alone ranks 21 of 51 states for electricity price.
Next step: home charger installation
The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
Ask a licensed Oregon electrician to quote the install before this math becomes a real decision.
Where these figures come from
Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. At 15.31¢/kWh, Oregon sits in the middle of the national range — the guide to why charging cost varies by state shows where.
