EV Charging in California: What the Numbers Mean
California's residential electricity rate is 30.6¢/kWh — 14.5¢ above the national average of 16.1¢/kWh, which narrows EV savings somewhat. At that rate, a typical EV (3.5 mi/kWh) costs $1049/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $4.85/gal ($1940/year for the same miles), EV home charging saves $891/year — $4,455 over 5 years, before incentives.
Home Charging vs Public Charging in California
The biggest driver of EV cost is where you charge. Home charging at 30.6¢/kWh is always the cheapest option. Public Level 2 stations average around 76.5¢/kWh — 2.5x more expensive. DC fast chargers run about 39.7¢/kWh. Tesla Superchargers in California are estimated at 46.0¢–55.0¢/kWh depending on membership.
Most EV owners do 80%+ of their charging at home overnight. If you don't have home charging access, the economics shift significantly — charging entirely at public DC fast chargers would cost $1361/year in California, narrowing the gap with gas considerably.
