To preserve the same standard of living you have today in Denver on $75,000, you would need $89,063 in Seattle. That is a +18.8% composite shift; the line-item breakdown below shows where the gap actually concentrates. Source: C2ER ACCRA, BLS CPI weights.
The salary you would need in Seattle to match your Denver purchasing power is your current salary times the index ratio 1.188. The three rows below show the result at the entry-level, mid-career, and senior anchor points most job posts negotiate around.
| Denver salary | Equivalent in Seattle | Difference |
|---|---|---|
| $50,000 | $59,375 | +$9,375 |
| $75,000 | $89,063 | +$14,063 |
| $150,000 | $178,125 | +$28,125 |
The breakdown below decomposes the Denver-vs-Seattle cost-of-living gap into its five constituent sub-indexes. National average for each is 100; the delta column shows how each line item changes between the two metros. Housing routinely shows the largest swing.
| Category | Denver | Seattle | Delta |
|---|---|---|---|
| Housing Rent + median home price | 166 | 198 | +19.3% |
| Groceries Supermarket basket | 102 | 113 | +10.8% |
| Transportation Fuel, transit, parking | 105 | 122 | +16.2% |
| Healthcare Doctor visits, prescriptions | 104 | 118 | +13.5% |
| Utilities Electric, gas, internet | 96 | 110 | +14.6% |
| Composite | 128 | 152 | +18.8% |
Seattle, WA is not a casual upgrade from Denver, CO: the composite cost-of-living index runs about 19% higher, with housing leading the gap at roughly 19% above Denver's baseline. Utilities and groceries follow the same direction at smaller magnitudes. Transportation can either compress or amplify the gap depending on whether you are giving up a car (likely in dense Seattle neighborhoods) or keeping one and paying Seattle-rate insurance, parking, and fuel.
The right way to think about this move is in terms of trade-offs, not pure cost. Higher rent buys access to a different labor market, different professional networks, different cultural offerings. Whether that trade is worth it depends on what you do for work and how much of your time is spent inside the city versus on a screen at home. The cost-of-living delta is the price tag; the question this page cannot answer is whether the thing you are buying is worth it for your specific career arc.
Consumer-price indexes exclude income tax, so the equivalent-salary number above is a pre-tax comparison. Layered on top: Colorado has a top-marginal or flat state income tax of 4.40%, while Washington's is 0.00%. At a $75,000 salary, that translates to roughly $3,300 of state tax owed in Colorado versus $0 in Washington — a $3,300 difference that no consumer-price index captures.
Plug your real numbers into the take-home pay calculator to see the after-tax difference at your filing status and salary. Federal withholding is constant; the state side is what changes when you cross state lines. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
Short answer: yes. Seattle runs 19% above Denver on the C2ER ACCRA composite (152 vs 128). Housing is the dominant driver of that gap; non-housing categories contribute smaller pieces in the same direction.
Approximately $89,063. The math: $75,000 times the index ratio 1.19 (which is 152/128) equals the salary in Seattle that preserves your real-terms spending power. State tax sits on top — handled separately in the sidebar above.
Housing carries the gap. Denver indexes at 166 on housing; Seattle indexes at 198. The other categories — groceries (102 vs 113), transportation (105 vs 122), utilities (96 vs 110) — move smaller distances. Housing variance is what makes metros feel meaningfully different on cost.
State tax is a separate adjustment. The composite cost-of-living index is a pre-tax, consumer-prices-only measure. Colorado and Washington state-tax rates differ; the sidebar quantifies that gap at common salary anchors so you can add it to the consumer-price equivalent and get an after-tax number.
