EV vs Gas Cost Per Mile in Oregon
At Oregon's average prices, a Tesla Model 3 RWD costs an estimated $0.040 a mile to charge at home and a 30 mpg gas car $0.130 a mile in fuel: $1,082.40 a year apart over 12,000 miles. Charging here costs about a third or less of gasoline per mile: 31%.

Oregon has more EVs on the road, relative to its size, than most states. At the end of 2025 it had 98,000 all-electric cars and light trucks registered plus 38,900 plug-in hybrids. That is 2.8% of the state's 3,558,000 light-duty vehicles, against 2.1% nationally, and the 8th-highest share of any state. Per household the picture is the same: 5.9 EVs per hundred homes against 4.6 for the US, again the 8th-highest.
Public charging has grown with the fleet. The state counts 1,659 public charging locations with 4,333 ports, of which 2,950 are Level 2 and 1,348 are DC fast. DC fast ports are 31% of the total, in line with the US share of 30%. Spread over the fleet that works out to 22.6 EVs per public port, close to the US figure of 21.7, so Oregon is neither unusually crowded nor unusually well supplied at the plug. Most charging still happens at home, which is the price this page is built on.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Oregon
At 15.9¢/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 $0.040. A 30 mpg car at $3.90/gal spends $0.130 a mile. Over 12,000 miles: $477.60 for the EV, $1,560.00 for gasoline, a difference of $1,082.40 a year (fuel only). A gas car would need about 98 mpg to match the EV's cost per mile in Oregon.
What the numbers say
What the numbers say in Oregon
Driving electric in Oregon pays off more than in almost any other state, and the reason is on the gasoline side as much as the electric one. Gasoline costs $3.90/gal here, 22% above the US average of $3.20/gal and the 4th-highest pump price in the country, while home electricity costs 15.9¢/kWh, 12% below the US average of 18.2¢/kWh. Expensive gas and cheap power are the two things that widen the gap, and both point the same way: $0.040 a mile for the Tesla Model 3 RWD against $0.130 for a 30 mpg car, a difference of $1,082.40 a year over 12,000 miles. That is the 3rd-highest yearly gap among the states at their average prices.
The margin is wide enough to survive a lot. The EV would cost the same per mile as the gas car only at an electricity rate of 52.0¢/kWh, against a state average of 15.9¢/kWh, or against a gas car rated at 98 mpg. A public Level 2 session priced above the home rate still leaves the EV ahead as long as the price stays under that break-even rate; DC fast charging priced per kilowatt-hour can approach it, so the fleet-wide ratio of 22.6 EVs per port matters less here than the price printed on the charger. Type that price into the electricity field above to see the cost per mile on the road.
What the registration numbers add is context for the charging question. With 3.8% of vehicles carrying a plug and 1,348 fast ports in the state, public charging is a convenience for trips, not a necessity for daily driving. The savings in this estimate assume home charging at the average residential rate; if your utility offers a time-of-use plan, the overnight rate replaces 15.9¢/kWh in the field above and the cost per mile falls in proportion.
Two things this comparison leaves out: the purchase price of the car and the charger. The plug-in hybrid vs EV vs gas page adds the car; the Level 2 installation cost page adds the charger. For the monthly bill of a specific model, see EV charging cost by model.
Questions
FAQ
Is charging an EV cheaper than gas in Oregon?
At Oregon's average prices, yes for the page's example: $0.040 a mile for a Model 3 RWD at home against $0.130 for a 30 mpg car, $1,082.40 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 52.0¢/kWh, or against a gas car rated above 98 mpg. Both prices are editable above.
What about public fast charging in Oregon?
Fast chargers usually charge more per kWh than a home rate. This page uses Oregon's home average, 15.9¢/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 $3.90/gal.
How do time-of-use rates change this in Oregon?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 15.9¢/kWh (8.0¢/kWh), the Model 3 RWD would cost $0.020 a mile instead of $0.040. Check your utility's tariff for the real overnight rate and type it in.
How much does it cost to charge an EV at home in Oregon?
At the state's average residential rate of 15.9¢/kWh, the Tesla Model 3 RWD used on this page costs $0.040 a mile, or $477.60 a year for 12,000 miles. A larger vehicle uses more: the Ford F-150 Lightning on the same rate comes to $0.076 a mile. Your own rate is on your bill; an overnight time-of-use rate, if you have one, is the number to use for charging.
Is public charging in Oregon enough for a road trip?
The state lists 1,659 public charging locations and 1,348 DC fast ports, the 18th-highest count among the states. What this page cannot tell you is where they are or what they charge; the price per kilowatt-hour at a fast charger is usually well above the home rate, and the cost per mile rises in proportion. For the trip itself, the cold-weather range page shows how winter cuts the distance between stops.
