Worked example
Worked example: Model 3 RWD vs a 30 mpg car in New Mexico
At 16.1¢/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 $0.040. A 30 mpg car at $3.00/gal spends $0.100 a mile. Over 12,000 miles: $482.70 for the EV, $1,200.00 for gasoline, a difference of $717.30 a year (fuel only). A gas car would need about 75 mpg to match it.
Questions
FAQ
Is charging an EV cheaper than gas in New Mexico?
At New Mexico's average prices, yes for the page's example: $0.040 a mile for a Model 3 RWD at home against $0.100 for a 30 mpg car, $717.30 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 40.0¢/kWh, or against a gas car rated above 75 mpg. Both prices are editable above.
What about public fast charging in New Mexico?
Fast chargers usually charge more per kWh than a home rate. This page uses New Mexico's home average, 16.1¢/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 $3.00/gal.
How do time-of-use rates change this in New Mexico?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 16.1¢/kWh (8.0¢/kWh), the Model 3 RWD would cost $0.020 a mile instead of $0.040. Check your utility's tariff for the real overnight rate and type it in.
