How This Calculator Works
Calculation methodology and assumptions
This calculator compares the cost of driving an EV versus a gas vehicle the same number of miles in Oregon. EV cost per mile is calculated as (kWh used per 100 miles ÷ 100) × your electricity rate; gas cost per mile is your gas price ÷ your vehicle's combined MPG. The electricity rate defaults to Oregon's actual average residential price of 16.27¢/kWh (U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.A, May 2026) -- the rate most home EV charging is billed at. The gas price defaults to the U.S. national average of $4.48/gallon (EIA Gasoline and Diesel Fuel Update, May 2026); edit it to your local price for a more precise result. Default vehicle efficiency figures (30 kWh/100mi for the EV, 32 MPG for the gas vehicle) are typical examples for mainstream compact/midsize vehicles -- look up your specific make and model's EPA rating at fueleconomy.gov and enter it for an exact comparison. This calculator does not model any federal or state EV purchase tax credit or rebate, vehicle price difference, insurance, or maintenance cost -- it isolates the ongoing fuel/energy cost difference only.

Example Calculation
Here's a practical example using Oregon's data.
The calculator uses state-specific public data and documented estimates where available — including tax rates, median values, and cost benchmarks — to produce a personalized estimate for the inputs you provide.
Result: Results will vary based on your individual inputs. Use this calculator as a starting point, then adjust the values to test different scenarios. The methodology section below explains exactly how each result is calculated.
What Affects Your Results
State-Specific Inputs
Oregon has unique rates, fee schedules, and regulatory requirements that can affect results. This page's methodology and source card identify which inputs are sourced, modeled, or user-adjustable.
Income Level
Many calculations are income-dependent due to progressive tax brackets, phase-outs, or income-based eligibility thresholds. Higher income doesn't always mean proportionally higher costs.
Local Variations
State averages may not reflect your specific city or county. Local taxes, fees, and market conditions can vary ±20% from state averages.
Annual Changes
Tax rates, fee schedules, and regulations change. Check the recorded source-review date and verify critical numbers with the relevant agency.
Tips for Oregon Residents
- Always verify pre-filled values against your actual data. State averages are a good starting point but your situation may differ significantly.
- Run multiple scenarios by adjusting key inputs to see how changes affect your results. This helps with planning and decision-making.
- Compare your results across states using the related calculators linked below — especially valuable if you're considering relocating or doing business in Oregon.
- Bookmark this page to recalculate periodically as rates change. Check the page source card and review date before relying on a pre-filled value.
- Consult a qualified professional for major financial decisions. These calculators provide estimates based on standard formulas — a CPA or financial advisor can factor in your complete financial picture.

Our editorial standardsFrequently Asked Questions
How much does it cost to charge an EV in Oregon?
At Oregon's average residential electricity rate of 16.27¢/kWh (EIA, May 2026), charging an EV that uses 30 kWh per 100 miles costs about $0.05 per 100 miles, or roughly $586/year for 12,000 miles of driving. Actual cost depends on your specific EV's efficiency and whether you charge at home or at a (typically pricier) public fast-charging station.
Is an EV actually cheaper to "fuel" than a gas car?
In most states, yes -- electricity is typically cheaper per mile than gasoline, even though EV efficiency and gas prices both vary. Use this calculator with your own vehicle's EPA-rated efficiency (from fueleconomy.gov) and your local gas price for an exact answer, since the size of the savings depends heavily on both numbers.
Does this include the cost of buying the EV or a tax credit?
No -- this calculator isolates only the ongoing fuel/energy cost difference. It does not model vehicle purchase price, financing, insurance, maintenance, or any federal or state EV tax credit or rebate. The federal EV purchase tax credit's status has changed multiple times via legislation, so check irs.gov or fueleconomy.gov for current eligibility before assuming one applies.
Is public EV charging more expensive than charging at home?
Generally yes -- public Level 2 and DC fast charging typically cost more per kWh than residential electricity rates because they include the charging network's equipment, maintenance, and profit margin. This calculator uses your home residential rate by default; if you charge mostly at public stations, your real-world cost will be higher than shown here.
What is Oregon's average electricity rate?
Oregon's average residential electricity price was 16.27¢/kWh in May 2026, according to the U.S. Energy Information Administration's Electric Power Monthly report (Table 5.6.A).
