What the Colorado numbers say
- Electricity: Colorado residential average is 16.72¢/kWh year-to-date through July 2026, 8% below the U.S. average of 18.19¢. It is up 8.0% from the same period in 2025. Latest single month (July 2026): 17.00¢.
- Gasoline: $4.27/gal (EIA state series), up $1.52 from a year ago. The U.S. average is $4.28.
- Cost-equivalent MPG: a gas car would need about 64 mpg to cost the same per mile as this EV in Colorado.
- If prices move: at 20% cheaper gas ($3.42) the yearly EV saving would be $660; at 20% higher electricity (20.06¢) it would be $930.
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.
