$75,000 in Seattle maps to roughly $63,158 of equivalent purchasing power in Denver on consumer prices alone. The composite index gap is -15.8%, with housing carrying -16.2% of that move. Source: C2ER ACCRA quarterly cost-of-living index, BLS CPI 2024 weights.
The equivalent-salary calculation scales your Seattle salary by the ratio of the two composite indexes (128 ÷ 152 = 0.842). It answers "how much do I need to earn in Denver to maintain the same consumer-spending power I have today in Seattle?"
| Seattle salary | Equivalent in Denver | Difference |
|---|---|---|
| $50,000 | $42,105 | -$7,895 |
| $75,000 | $63,158 | -$11,842 |
| $150,000 | $126,316 | -$23,684 |
Five sub-indexes feed the composite cost-of-living number. Housing dominates, but the other four — groceries, transport, healthcare, utilities — each carry weight in any real household budget. Here is how Seattle and Denver stack up category by category against the national-average baseline of 100.
| Category | Seattle | Denver | Delta |
|---|---|---|---|
| Housing Rent + median home price | 198 | 166 | -16.2% |
| Groceries Supermarket basket | 113 | 102 | -9.7% |
| Transportation Fuel, transit, parking | 122 | 105 | -13.9% |
| Healthcare Doctor visits, prescriptions | 118 | 104 | -11.9% |
| Utilities Electric, gas, internet | 110 | 96 | -12.7% |
| Composite | 152 | 128 | -15.8% |
The composite index gap between Seattle, WA and Denver, CO is real: roughly 16 index points separate the two metros on C2ER ACCRA's published quarterly cost-of-living survey. Translated to a household budget, that gap shows up most loudly in housing (16% lower in Denver), with secondary effects on utilities and groceries. Healthcare and transportation move less between the two cities — those line items track regional patterns more than metro-specific ones.
What this means for a relocation decision: every dollar of Seattle salary stretches further in Denver, but the stretch is not uniform across categories. A family-of-four budget heavy on housing and groceries sees a bigger improvement than a single renter who already keeps rent low and spends mostly on dining and travel. Sketch your actual category mix before deciding what a "fair" pay adjustment looks like — most remote-pay zone formulas under-credit the housing-heavy household and over-credit the dining-heavy one.
The cost-of-living index is a pre-tax measure. Add state tax to get the after-tax picture: Washington at 0.00% versus Colorado at 4.40%. The $75,000 anchor shows $0 owed in Washington versus $3,300 in Colorado, a $3,300 swing on top of the consumer-price gap.
The take-home pay calculator gives you the after-tax delta at your real salary and filing status. Federal tax is invariant under the move; the state rate is the only piece that flips. 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, Denver 128. Denver is roughly 16% less expensive overall, with the housing sub-index doing most of the work and other categories contributing smaller deltas.
Plan on roughly $63,158 of gross salary in Denver to match $75,000 of Seattle purchasing power. The calculation uses the C2ER ACCRA composite ratio (128/152 = 0.84). That is pre-tax; the state-tax sidebar handles the after-tax piece.
Housing — and it isn't close. Seattle's housing index is 198; Denver's is 166. The remaining sub-indexes (groceries 113/102, transport 122/105, utilities 110/96) 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 Colorado 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.
