Estimates only. Public DC fast charging usually costs more per kWh than home charging, so a higher public share raises your bill. For the most accurate result, use your actual electricity rate from your utility bill.

Home Level 2 chargers

Charging at home on your residential rate is the cheapest way to cover the miles above. Most non-Tesla EVs built before 2025 have a J1772 port; a NACS car takes the wall charger's NACS version. The portable unit plugs into an existing 14-50 outlet on a 50 A circuit with no install. It is J1772-only.

Frequently asked questions

For a typical driver covering ~1,000 miles a month in an EV that gets 3.5 mi/kWh, charging mostly at home at the U.S. average electricity rate runs roughly $35–$50 per month. Your number depends on your miles, your car's efficiency, your electricity rate, and how much you charge on pricier public DC fast chargers.
