What the Ohio numbers say
- Electricity: Ohio residential average is 18.70¢/kWh year-to-date through July 2026, 3% above the U.S. average of 18.19¢. It is up 13.0% from the same period in 2025. Latest single month (July 2026): 19.45¢.
- Gasoline: $4.05/gal (EIA state series), up $1.04 from a year ago. The U.S. average is $4.28.
- Cost-equivalent MPG: a gas car would need about 56 mpg to cost the same per mile as this EV in Ohio.
- If prices move: at 20% cheaper gas ($3.24) the yearly EV saving would be $526; at 20% higher electricity (22.44¢) it would be $765.
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.
