What the Oregon numbers say
- Electricity: Oregon residential average is 15.40¢/kWh year-to-date through July 2026, 15% below the U.S. average of 18.19¢. It is up 1.4% from the same period in 2025. Latest single month (July 2026): 15.97¢.
- Gasoline: $5.01/gal (EIA regional series: West Coast less California), up $1.13 from a year ago. The U.S. average is $4.28.
- Cost-equivalent MPG: a gas car would need about 78 mpg to cost the same per mile as this EV in Oregon.
- If prices move: at 20% cheaper gas ($4.01) the yearly EV saving would be $949; at 20% higher electricity (18.48¢) it would be $1,290.
What this leaves out: purchase price, tax credits, insurance, maintenance, depreciation, home charger installation, time-of-use rates and cold-weather range loss. Your utility's own rate may differ from the state average. See the methodology.
