EV vs Gas Cost Per Mile in Oklahoma
At Oklahoma's average prices, a Tesla Model 3 RWD costs an estimated $0.037 a mile to charge at home and a 30 mpg gas car $0.093 a mile in fuel: $675.40 a year apart over 12,000 miles. Per mile, the EV spends about 40% of what the gas car does.

Plug-in hybrids are unusually common in Oklahoma's small plug-in fleet. At the end of 2025 the state had 29,100 of them registered, more than its 26,800 all-electric cars and light trucks; nationally, battery EVs outnumber plug-in hybrids, 5,689,100 to 1,765,700. Out of 3,855,800 light-duty vehicles, the all-electric share is 0.7%, the 40th-highest among the 51 states and well short of the US 2.1%. Counting both kinds of plug, 1.4% of vehicles can charge from the grid. Per hundred homes there are 1.8 EVs, against 4.6 for the country.
The public network is built mostly of fast chargers, which is rare. Of 1,667 ports at 397 locations, 1,022 are DC fast and only 644 are Level 2, so fast ports are 61% of the total where the US average is 30%. That leaves 26 EVs per fast port, against 72 nationally, and 16.1 EVs per port of any kind (US: 21.7). Slower public plugs for a long stop at work or in town are the thinner part of the network.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Oklahoma
At 14.8¢/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 $0.037. A 30 mpg car at $2.80/gal spends $0.093 a mile. Over 12,000 miles: $444.60 for the EV, $1,120.00 for gasoline, a difference of $675.40 a year (fuel only). That difference is the 35th-highest of the 51 on this site.
What the numbers say
What cheap gasoline does to the EV math in Oklahoma
Oklahoma has the lowest gasoline price in the country, $2.80/gal, 13% below the US average of $3.20/gal, and that narrows the case for an EV more than anything on the electric side. Home power is also inexpensive at 14.8¢/kWh, 18% below the US average of 18.2¢/kWh, which keeps the EV clearly ahead: $0.037 a mile for the Tesla Model 3 RWD against $0.093 for a 30 mpg car, a yearly difference of $675.40 over 12,000 miles. Among the states, that gap ranks the 17th-lowest, because the gasoline it competes with is so cheap.
Even so, the result is not fragile at home rates. The two cars would cost the same per mile only at 37.3¢/kWh for electricity, far from the state's 14.8¢/kWh, or with a gas car that reached 76 mpg. The place where the margin can shrink is the public network, and in Oklahoma public charging is mostly DC fast. A fast-charging session priced per kilowatt-hour well above the home rate can bring the cost per mile close to the gas car's; enter the charger's price in the electricity field above to see where it lands.
With so many plug-in hybrids here, the plug-in hybrid vs EV vs gas page is the natural next step: it adds the gasoline miles a hybrid still drives. If your utility offers a time-of-use plan, charging overnight at half the average rate, 7.4¢/kWh, would bring the EV to $0.019 a mile. For the monthly cost of charging specific models at your own rate, use EV charging cost.
Questions
FAQ
Is charging an EV cheaper than gas in Oklahoma?
At Oklahoma's average prices, yes for the page's example: $0.037 a mile for a Model 3 RWD at home against $0.093 for a 30 mpg car, $675.40 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 76 mpg. Both prices are editable above.
What about public fast charging in Oklahoma?
Fast chargers usually charge more per kWh than a home rate. This page uses Oklahoma's home average, 14.8¢/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 Oklahoma?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 14.8¢/kWh (7.4¢/kWh), the Model 3 RWD would cost $0.019 a mile instead of $0.037. Check your utility's tariff for the real overnight rate and type it in.
Plug-in hybrids outnumber EVs in Oklahoma. Is a hybrid the cheaper choice?
It depends on how many of your miles run on the battery. A plug-in hybrid driven on electricity costs about what an EV does per mile at 14.8¢/kWh; on gasoline at $2.80/gal it costs what a gas car does. The full EV here runs at $0.037 a mile against $0.093 for a 30 mpg car. The plug-in hybrid vs EV vs gas page lets you set the electric share of your driving and adds the purchase price.
Why does Oklahoma have more fast chargers than Level 2 chargers?
The station data only counts them: 1,022 DC fast ports against 644 Level 2 ports, a fast share of 61% next to 30% nationally. For a driver, it means a public top-up is more likely to be a quick, more expensive fast session than a slow, cheaper one. Daily charging at home, at 14.8¢/kWh on average, is the price that the estimate on this page uses.
