Energy
For 12,000 miles: EV about $623 at home (18.16¢/kWh), compared with $1,714 for a 30 MPG car at $4.284/gal. That’s about $1,091 a year less. Sources: EIA electricity, EIA gasoline.
Other costs
- Maintenance: EVs need no oil changes, and regenerative braking means the brakes wear more slowly. Tires can wear faster on heavier cars.
- Registration: many states add an EV fee. See the AFDC state laws search.
- Insurance: it varies by model and insurer, so get a quote before you buy.
- Incentives: federal credits have ended (IRS).
If you mostly fast charge, the energy saving shrinks a lot. See public charging.
About sales tax
US prices on this page are shown as published. Gas pump prices already include federal and state fuel taxes; electricity rates and public charging may have state and local sales tax added on top, and that varies by state, county and city, so we don't split it out. Check your bill or the charger app for the tax that applies to you.
