What the Louisiana numbers say
- Electricity: Louisiana residential average is 13.35¢/kWh year-to-date through July 2026, 27% below the U.S. average of 18.19¢. It is up 5.9% from the same period in 2025. Latest single month (July 2026): 12.72¢.
- Gasoline: $3.78/gal (EIA regional series: Gulf Coast (PADD3)), up $1.23 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 Louisiana.
- If prices move: at 20% cheaper gas ($3.03) the yearly EV saving would be $589; at 20% higher electricity (16.02¢) it would be $836.
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.
