EV vs Gas in Oregon: Which Is Cheaper in 2026?
A Oregon driver covering 12,000 miles a year pays about $827 to charge an EV versus $2,146 to fuel a 26 MPG petrol car. Electric saves about $1,319 a year — about 61% less.

Home charging is the whole ballgame
In Oregon a public fast charge costs roughly 3.2× the home rate. Charging entirely at home costs $577 a year here; leaning on public chargers for a fifth of your miles pushes that to $827. If you cannot charge where you park, the running-cost case weakens sharply — and in cheap-gas, expensive-electricity states it can disappear entirely.
Common questions
Is an EV cheaper than gas in Oregon?
On fuel alone, yes. At 15.14¢ per kWh and $4.65 a gallon, 12,000 miles costs about $827 in electricity versus $2,146 in gas — a difference of $1,319 a year, assuming 80% home charging.
How much does it cost to charge an EV at home in Oregon?
A full year of driving needs roughly 3,810 kWh from the wall. Charged entirely at home at 15.14¢, that is about $577 a year, or 4.8¢ per mile. Note you pay for about 10% more electricity than reaches the battery.
Does public fast charging cancel out the savings?
It can. Public DC fast charging runs around $0.48 per kWh — roughly 3.2× the home rate in Oregon. Charging entirely at home costs $577 a year here; at 80% home charging it rises to $827. Without home charging, an EV can genuinely cost more to fuel than a petrol car.
At what gas price do the two break even in Oregon?
About $1.79 a gallon. Below that, a 26 MPG petrol car is cheaper to fuel; above it, the EV pulls ahead. Oregon currently averages roughly $4.65.
Does this include the cost of buying the car?
No. This is fuel cost only. Purchase price, depreciation, insurance, maintenance and any tax credits are excluded — and they often matter more than fuel. Use this to size the running-cost gap, then weigh it against the price difference between the two cars.
How we calculate this
We charge you for electricity drawn from the wall, not delivered to the battery — about 10% is lost as heat, which most calculators quietly ignore. We also blend home and public charging rather than assuming every kWh comes from a cheap home tariff.
Fuel only. Purchase price, depreciation, insurance, maintenance, registration fees (several states levy an EV surcharge in place of fuel tax) and tax credits are all excluded.
