Worked example

Worked example: Model 3 RWD vs a 30 mpg car in Alabama

At 16.4¢/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 $0.041. A 30 mpg car at $2.90/gal spends $0.097 a mile. Over 12,000 miles: $492.00 for the EV, $1,160.00 for gasoline, a difference of $668.00 a year (fuel only). The EV's cost per mile would match gas only above 38.7¢/kWh.

Questions

FAQ

Is charging an EV cheaper than gas in Alabama?

At Alabama's average prices, yes for the page's example: $0.041 a mile for a Model 3 RWD at home against $0.097 for a 30 mpg car, $668.00 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 38.7¢/kWh, or against a gas car rated above 71 mpg. Both prices are editable above.

What about public fast charging in Alabama?

Fast chargers usually charge more per kWh than a home rate. This page uses Alabama's home average, 16.4¢/kWh. To see the cost per mile on the road, type the charger's price per kWh into the electricity rate field; the gas side stays at $2.90/gal.

How do time-of-use rates change this in Alabama?

The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 16.4¢/kWh (8.2¢/kWh), the Model 3 RWD would cost $0.021 a mile instead of $0.041. Check your utility's tariff for the real overnight rate and type it in.
