EV vs Gas Cost Per Mile in New Mexico
At New Mexico's average prices, a Tesla Model 3 RWD costs an estimated $0.041 a mile to charge at home and a 30 mpg gas car $0.100 a mile in fuel: $704.70 a year apart over 12,000 miles. At these prices, home charging costs half or less of gasoline per mile in New Mexico.

New Mexico is short on EVs but well supplied with chargers for the ones it has. The 2025 registration tally shows 16,600 battery-electric vehicles and 7,100 plug-in hybrids. Out of 1,777,700 cars and light trucks statewide, EVs make up 0.9%, the 30th-highest share in the country, against 2.1% for the US; that is 2.1 per hundred households where the nation has 4.6.
The charging network is unusual in its balance. Across 494 public sites there are 1,276 ports, and the two kinds sit close together: 621 DC fast and 653 Level 2. Fast ports therefore make up 49% of the total, a much bigger share than the US 30%. With so few EVs to serve, each public port has 13.0 of them, the 16th-lowest ratio among the states and below the US 21.7, and each fast port has 27, compared with 72 nationally. Drivers who cover long stretches between towns are the ones that mix serves best.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in New Mexico
At 16.5¢/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 $3.00/gal spends $0.100 a mile. Over 12,000 miles: $495.30 for the EV, $1,200.00 for gasoline, a difference of $704.70 a year (fuel only). A gas car would need about 73 mpg to match it.
What the numbers say
What the numbers say in New Mexico
Two prices decide the EV comparison in New Mexico, and both sit below the national level. Electricity for the home costs 16.5¢/kWh, 9% below the US average of 18.2¢/kWh; gasoline costs $3.00/gal, 6% below the US average of $3.20/gal. The modest pump price takes something off the EV's lead and the modest power price gives it back, so the page's yearly saving ranks the 27th-highest among the states, each priced at its usual level.
There is enough slack to absorb road charging. Per mile, the EV and the 30 mpg car break even only when a kilowatt-hour costs 40.0¢/kWh, well above the 16.5¢/kWh state average, or when the gas car gets 73 mpg. With fast ports making up such a large part of the network, intercity trips here are likely to run on DC fast charging, and the break-even price is the number to hold up against the one on the charger's display. Enter that displayed price in the electricity box above to get the per-mile cost on the road; anything under the break-even still leaves the EV ahead on fuel.
How far you drive matters as much as where you live. Each mile charged away from home is billed at a public price instead of 16.5¢/kWh, so heavy highway use pulls the two cars closer. A driver who stays local and plugs in at night gets roughly the page's figure; one who crosses the state weekly should also run the calculator at a fast-charger price.
New Mexico winters are lighter than the national norm at 4,000 heating degree-days, 11% fewer than the US average of 4,500, yet a cold start still costs some range, and the cold-weather range calculator estimates the loss. To price a garage charger, use Level 2 installation cost; if your utility sells cheaper off-peak power, enter that night rate where 16.5¢/kWh is now. Heating a home here is covered on the New Mexico heating page.
Questions
FAQ
Is charging an EV cheaper than gas in New Mexico?
At New Mexico's average prices, yes for the page's example: $0.041 a mile for a Model 3 RWD at home against $0.100 for a 30 mpg car, $704.70 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 73 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, 16.5¢/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 16.5¢/kWh (8.3¢/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.
How long will a stop at a public charger in New Mexico take?
Mostly that comes down to which kind of plug you use. New Mexico lists 1,276 public ports: 621 DC fast and 653 Level 2. A Level 2 post refills a battery far more slowly than a fast charger, so on a trip it is the fast ports that count. Give the charge time calculator your car, the charger and your starting charge to get the minutes.
Do long drives in New Mexico erase an EV's fuel savings?
Not while the price per kWh you pay stays below 40.0¢/kWh, where the EV and a 30 mpg car on $3.00/gal gasoline cost the same per mile. That is simple at the 16.5¢/kWh home rate and depends on the station's price when you are on the road. With 621 fast ports and 27 EVs for each, against 72 nationally, finding a free plug is less of an issue than the gaps between them; look at the stations along your usual routes first.
