EV vs Gas Cost Per Mile in Mississippi
At Mississippi's average prices, a Tesla Model 3 RWD costs an estimated $0.036 a mile to charge at home and a 30 mpg gas car $0.093 a mile in fuel: $687.10 a year apart over 12,000 miles. Per mile, the EV spends about 39% of what the gas car does.

Electric cars are rare in Mississippi. The 2025 registration data list 7,200 all-electric vehicles and 3,000 plug-in hybrids in a light-duty fleet of 2,413,100, which makes the EV share 0.3%, the 2nd-lowest of the 51, against 2.1% for the country. Per household it is 0.7 EVs for every hundred homes, again the 2nd-lowest, where the US average is 4.6. Conventional hybrids, at 64,000, are much more common than plug-ins.
The public network is small but tilted toward speed. There are 708 ports at 225 locations, the 7th-lowest total in the country, and 350 of them are DC fast, close to half the network at 49%, against 30% nationally. Level 2 ports number 358. With so few EVs, the ratios look generous: 10.2 EVs per port and 21 per fast port, compared with 21.7 and 72 for the US. What the ratios cannot show is how far apart the stations are.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Mississippi
At 14.4¢/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 $0.036. A 30 mpg car at $2.80/gal spends $0.093 a mile. Over 12,000 miles: $432.90 for the EV, $1,120.00 for gasoline, a difference of $687.10 a year (fuel only). That difference is the 32nd-highest of the 51 on this site.
What the numbers say
What the numbers say in Mississippi
Mississippi has the lowest gasoline price in the country, $2.80 a gallon, 13% below the US average of $3.20/gal. That is the strongest argument a gas car has here, and it brings a 30 mpg car down to $0.093 a mile. Electricity is cheap too: 14.4¢/kWh, the 10th-lowest residential rate and 21% below the US average of 18.2¢/kWh. The Tesla Model 3 RWD runs at $0.036 a mile, and over 12,000 miles the EV saves $687.10 a year on fuel, the 32nd-highest gap among the states.
Even at $2.80 a gallon, the margin is wide. Home electricity would have to cost 37.3¢/kWh before the EV lost its fuel advantage, against a state average of 14.4¢/kWh; a gas car would need 78 mpg to match it. Where the margin narrows is public fast charging. With fast ports making up so much of the network, a driver without home charging would likely pay fast-charge prices often, and those are usually well above the home rate. Type a station's posted price per kWh into the electricity field above to see the cost per mile.
For most owners the cheapest charging is at home, and a time-of-use plan, if your utility offers one, lowers it further. At half the average rate, 7.2¢/kWh, the Tesla Model 3 RWD would cost $0.018 a mile. Check your tariff for the off-peak hours and set the car to charge inside them. Level 2 installation cost estimates a home circuit, though many drivers with short daily distances get by on Level 1; charge time shows how long each takes.

Questions
FAQ
Is charging an EV cheaper than gas in Mississippi?
At Mississippi's average prices, yes for the page's example: $0.036 a mile for a Model 3 RWD at home against $0.093 for a 30 mpg car, $687.10 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 78 mpg. Both prices are editable above.
What about public fast charging in Mississippi?
Fast chargers usually charge more per kWh than a home rate. This page uses Mississippi's home average, 14.4¢/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 $2.80/gal.
How do time-of-use rates change this in Mississippi?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 14.4¢/kWh (7.2¢/kWh), the Model 3 RWD would cost $0.018 a mile instead of $0.036. Check your utility's tariff for the real overnight rate and type it in.
Does cold weather cut EV range much in Mississippi?
Less than in most of the country. Mississippi has 2,300 heating degree-days, the 46th-highest count and 49% fewer than the US average of 4,500, so the days when a battery loses range to cold and cabin heating are fewer and milder. The yearly cost of $432.90 for 12,000 miles uses the EPA efficiency figure. For a cold snap, the cold-weather range calculator estimates the loss at any temperature.
Can I rely on public charging in Mississippi?
As a backup, often yes; as your only source, it is harder. The state has 708 public ports in total, 350 of them fast, and fast charging usually costs more per kilowatt-hour than charging at home. Check a station map along the roads you drive most before buying, and price your usual charger with the EV charging cost calculator.
