What the Wisconsin numbers say
- Electricity: Wisconsin residential average is 19.00¢/kWh year-to-date through July 2026, 4% above the U.S. average of 18.19¢. It is up 5.4% from the same period in 2025. Latest single month (July 2026): 19.06¢.
- Gasoline: $4.14/gal (EIA regional series: Midwest (PADD2)), up $1.34 from a year ago. The U.S. average is $4.28.
- Cost-equivalent MPG: a gas car would need about 57 mpg to cost the same per mile as this EV in Wisconsin.
- If prices move: at 20% cheaper gas ($3.32) the yearly EV saving would be $550; at 20% higher electricity (22.80¢) it would be $796.
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.
