Seattle to Portland on the C2ER ACCRA composite: -14.5% on the headline, -16.7% on housing alone. A $75,000 Seattle salary lines up with roughly $64,145 in Portland after the consumer-price adjustment. State tax stacks on top — sidebar below.
If your goal is to land in Portland with the same consumer-spending power you have in Seattle, multiply your current salary by 0.855. That ratio is the C2ER ACCRA composite index of Portland divided by the composite of Seattle (130/152).
| Seattle salary | Equivalent in Portland | Difference |
|---|---|---|
| $50,000 | $42,763 | -$7,237 |
| $75,000 | $64,145 | -$10,855 |
| $150,000 | $128,289 | -$21,711 |
The C2ER ACCRA composite index aggregates five spending categories. Looking at them individually shows where the Seattle-to-Portland gap actually comes from — the headline number is an average that compresses larger category-level differences. National average for each sub-index is 100.
| Category | Seattle | Portland | Delta |
|---|---|---|---|
| Housing Rent + median home price | 198 | 165 | -16.7% |
| Groceries Supermarket basket | 113 | 106 | -6.2% |
| Transportation Fuel, transit, parking | 122 | 112 | -8.2% |
| Healthcare Doctor visits, prescriptions | 118 | 110 | -6.8% |
| Utilities Electric, gas, internet | 110 | 95 | -13.6% |
| Composite | 152 | 130 | -14.5% |
The cost-of-living gap between Seattle, WA and Portland, OR is small on the composite measure (-14%) but the line-item picture is more textured. Housing alone moves by about -17%, which is larger than the composite because non-housing categories — groceries, healthcare, utilities — tend to move together across U.S. metros and partially offset each other in the composite.
The right interpretation: do not let the small composite number lead you to assume the two cities are interchangeable. Your specific budget mix will determine the actual change in monthly outlays. A high-savings, low-housing household will see a small net change. A housing-heavy household will see something closer to the housing sub-index gap. Sketch your three biggest line items before treating this move as a financial non-event.
The cost-of-living index is a pre-tax measure. Add state tax to get the after-tax picture: Washington at 0.00% versus Oregon at 9.90%. The $75,000 anchor shows $0 owed in Washington versus $7,425 in Oregon, a $7,425 swing on top of the consumer-price gap.
Model the precise after-tax difference with the take-home pay calculator using your specific filing status and salary. Federal tax is identical regardless of which state you live in; only the state component moves. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
The data says no. Composite indexes: Seattle 152, Portland 130. Portland is roughly 14% less expensive overall, with the housing sub-index doing most of the work and other categories contributing smaller deltas.
To maintain the same standard of living you have in Seattle, WA on $75,000, you would need to earn approximately $64,145 in Portland, OR. The formula is straightforward: multiply your current salary by the ratio of the two cost-of-living indexes (130 ÷ 152 = 0.86). The result covers consumer prices but not state income tax differences — see the state-tax sidebar for that adjustment.
Housing — and it isn't close. Seattle's housing index is 198; Portland's is 165. The remaining sub-indexes (groceries 113/106, transport 122/112, utilities 110/95) contribute, but the housing line is what produces the noticeable real-world budget difference.
They are tracked separately. The cost-of-living composite measures consumer prices; state income tax is a different axis. Washington and Oregon can disagree on tax by several thousand dollars per year at typical salaries, and that delta stacks with — not into — the consumer-price gap above.
