Worked example
Worked example: Model 3 RWD vs a 30 mpg car in District of Columbia
At 25.2¢/kWh, a Model 3 RWD (25 kWh per 100 miles, EPA) draws 25 kWh from the wall for every 100 miles (the EPA measures it at the wall), so each mile costs $0.063. A 30 mpg car at $3.40/gal spends $0.113 a mile. Over 12,000 miles: $756.30 for the EV, $1,360.00 for gasoline, a difference of $603.70 a year (fuel only). The EV would lose its per-mile edge above 45.3¢/kWh, or against a gas car rated above 54 mpg.
