Worked example
Worked example: Model 3 RWD vs a 30 mpg car in New Jersey
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 $3.10/gal spends $0.103 a mile. Over 12,000 miles: $755.70 for the EV, $1,240.00 for gasoline, a difference of $484.30 a year (fuel only). An overnight rate below 25.2¢/kWh widens it; see the time-of-use question below.
Questions
FAQ
Is charging an EV cheaper than gas in New Jersey?
At New Jersey's average prices, yes for the page's example: $0.063 a mile for a Model 3 RWD at home against $0.103 for a 30 mpg car, $484.30 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 41.3¢/kWh, or against a gas car rated above 49 mpg. Both prices are editable above.
What about public fast charging in New Jersey?
Fast chargers usually charge more per kWh than a home rate. This page uses New Jersey's home average, 25.2¢/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 $3.10/gal.
How do time-of-use rates change this in New Jersey?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 25.2¢/kWh (12.6¢/kWh), the Model 3 RWD would cost $0.031 a mile instead of $0.063. Check your utility's tariff for the real overnight rate and type it in.
