EV vs Gas Cost Per Mile in Louisiana
At Louisiana's average prices, a Tesla Model 3 RWD costs an estimated $0.032 a mile to charge at home and a 30 mpg gas car $0.093 a mile in fuel: $733.90 a year apart over 12,000 miles. Louisiana pairs 12.9¢/kWh electricity with $2.80/gal gasoline, so the EV runs on about 34% of the gas car's fuel cost per mile.

Louisiana's home electricity costs 12.9¢/kWh, 29% below the US average of 18.2¢/kWh, the 2nd-lowest of the 51. At $2.80 a gallon, Louisiana is in the lowest gasoline band on this site ($2.90 or less), which narrows the EV's fuel-cost edge.

Louisiana has a modest EV fleet for its size. At the end of 2025 it had 22,600 all-electric cars and light trucks registered and 5,700 plug-in hybrids, 0.7% of its 3,369,100 light-duty vehicles against 2.1% nationally, the 11th-lowest share among the states. Per household that is 1.3 EVs per hundred homes against 4.6 for the US.
The public network is small and leans on fast charging. The state lists 259 charging locations with 852 ports, the 12th-lowest count in the country, with 427 at Level 2 and 425 DC fast. Fast ports are 50% of the total, against 30% nationally. The unusual figure is the load per plug: despite a small fleet, there are 26.5 EVs per public port against 21.7 for the US, the 7th-highest ratio among the states, because the port count is smaller still. Per fast port the figure is 53, against 72.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Louisiana
At 12.9¢/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 $0.032. A 30 mpg car at $2.80/gal spends $0.093 a mile. Over 12,000 miles: $386.10 for the EV, $1,120.00 for gasoline, a difference of $733.90 a year (fuel only). The $733.90 difference is the 20th-highest of the 51 on this site.
What the numbers say
What the numbers say in Louisiana
Louisiana pairs the 2nd-lowest electricity rate in the country with the lowest gasoline price. Home power costs 12.9¢/kWh, 29% below the US average of 18.2¢/kWh, and gasoline costs $2.80/gal, 13% below the US average of $3.20/gal. Cheap power makes the EV's cost per mile here, $0.032, low against the US figure of $0.045, but cheap gasoline lowers the gas car's cost too, which keeps the yearly gap from being larger.
The margin is still wide. The EV would match the gas car's cost per mile only at an electricity rate of 37.3¢/kWh, against a state average of 12.9¢/kWh, or against a gas car rated at 87 mpg. A fast-charging session priced well above the home rate narrows the gap but keeps the EV ahead while it stays under that break-even rate; type the charger's price into the electricity field above to check.
Because public plugs are scarce relative to the fleet, the home setup is the first thing to plan. A Level 1 outlet covers short daily trips; the Level 2 installation cost page prices a home charger for longer ones. Then check the tariff: if your utility offers a time-of-use plan, its overnight rate replaces 12.9¢/kWh in the calculator and lowers the cost per mile in proportion, from an already low starting point.
Winter is not a factor worth much worry here, with 1,800 heating degree-days, 60% fewer than the US average of 4,500. For a larger vehicle, the EV charging cost calculator gives the monthly figure by model. Home heating in Louisiana has its own page: gas vs electric heat.
Questions
FAQ
Is charging an EV cheaper than gas in Louisiana?
At Louisiana's average prices, yes for the page's example: $0.032 a mile for a Model 3 RWD at home against $0.093 for a 30 mpg car, $733.90 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 37.3¢/kWh, or against a gas car rated above 87 mpg. Both prices are editable above.
What about public fast charging in Louisiana?
Fast chargers usually charge more per kWh than a home rate. This page uses Louisiana's home average, 12.9¢/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 $2.80/gal.
How do time-of-use rates change this in Louisiana?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 12.9¢/kWh (6.4¢/kWh), the Model 3 RWD would cost $0.016 a mile instead of $0.032. Check your utility's tariff for the real overnight rate and type it in.
Why does Louisiana have so many EVs per public charger?
Not because the state has many EVs; it has few. It is because the port count is small too: 852 in all, the 12th-lowest count among the states, which works out to 26.5 EVs per port against 21.7 nationally. The fast ports are less crowded, 53 EVs each against 72. These are statewide averages; local availability varies, and this page does not map stations.
How cheap is it to charge an EV at home in Louisiana?
At the state's average rate of 12.9¢/kWh, the Tesla Model 3 RWD costs $0.032 a mile to charge at home, against $0.045 at the US average rate. Over 12,000 miles that is $386.10 a year. A pickup uses more: the Ford F-150 Lightning comes to $0.062 a mile on the same rate. An overnight time-of-use rate, if your utility offers one, would lower both.
