Gas prices jumped in 2026 when the war with Iran disrupted oil shipping through the Strait of Hormuz. Home electricity is priced by utilities under state regulators and moves far more slowly, so the gap tends to widen when gas spikes. For a 27 mpg car to cost less per mile than charging at home in Riverside, gas would have to fall below $1.78 a gallon.

We assume 1,000 miles a month, a typical new EV that uses 30 kWh per 100 miles, a 27 mpg gas car, and home charging at each utility's average residential rate, which includes its fixed monthly charges. An overnight or EV rate is often cheaper than that average, and public fast charging costs much more. Treat this as the honest average, not your bill.

About $1.78 to $2.55 a gallon, depending on your utility: $1.78 on Riverside Public Utilities and $2.55 on SCE. That is what a 27 mpg car would need to pay to match the cost per mile of charging at home.
At home, about $66 per 1,000 miles on Riverside Public Utilities (21.9 cents per kWh) or $94 per 1,000 miles on SCE (31.5 cents per kWh), for a typical EV that uses 30 kWh per 100 miles. Public fast charging costs much more per kWh than home charging, so these numbers assume you charge at home most of the time.
