Los Angeles to Seattle on the C2ER ACCRA composite: -8.4% on the headline, -7.9% on housing alone. A $75,000 Los Angeles salary lines up with roughly $68,675 in Seattle after the consumer-price adjustment. State tax stacks on top — sidebar below.
The equivalent-salary calculation scales your Los Angeles salary by the ratio of the two composite indexes (152 ÷ 166 = 0.916). It answers "how much do I need to earn in Seattle to maintain the same consumer-spending power I have today in Los Angeles?"
| Los Angeles salary | Equivalent in Seattle | Difference |
|---|---|---|
| $50,000 | $45,783 | -$4,217 |
| $75,000 | $68,675 | -$6,325 |
| $150,000 | $137,349 | -$12,651 |
Composite indexes hide the within-budget variance that often matters more than the headline. Housing in Los Angeles can be far above the city's composite, while groceries sit closer to par. The same is true for Seattle. Compare the five categories below to see where your specific budget mix changes the picture.
| Category | Los Angeles | Seattle | Delta |
|---|---|---|---|
| Housing Rent + median home price | 215 | 198 | -7.9% |
| Groceries Supermarket basket | 110 | 113 | +2.7% |
| Transportation Fuel, transit, parking | 132 | 122 | -7.6% |
| Healthcare Doctor visits, prescriptions | 103 | 118 | +14.6% |
| Utilities Electric, gas, internet | 121 | 110 | -9.1% |
| Composite | 166 | 152 | -8.4% |
Los Angeles, CA versus Seattle, WA: the composite cost-of-living index difference is about -8%, putting the move in the "lateral" zone where lifestyle, climate, career, and tax factors usually outweigh pure cost considerations. At this scale of gap, the noise inside the index (sampling variation, year-over-year price drift, individual basket differences) is roughly the same size as the signal between the two cities.
What is worth checking: are there meaningful state-tax differences between California and Washington? Is the housing sub-index gap larger or smaller than the composite gap, indicating that the categories you actually spend on diverge from the average mix? The sidebar and the tables below break out these dimensions so you can stress-test whether the lateral classification holds for your specific situation.
State income tax is not part of the cost-of-living composite, but it is part of your real take-home math. California's effective top rate is 9.30%; Washington's is 0.00%. On a $75,000 salary the two states pull $6,975 and $0 respectively — a gap of $6,975 that compounds with the consumer-price difference.
Run your actual salary and filing status through the take-home pay calculator for a precise after-tax number. The federal layer is the same in either metro; only the state piece shifts. 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: Los Angeles 166, Seattle 152. Seattle is roughly 8% less expensive overall, with the housing sub-index doing most of the work and other categories contributing smaller deltas.
The equivalent salary in Seattle is about $68,675. You get there by multiplying $75,000 by the index ratio (0.92, derived from 152 and 166). This is a consumer-price comparison; layer state tax separately for after-tax parity.
Housing is the largest line item in any cost-of-living comparison and the one with the most metro-to-metro variance. Los Angeles's housing sub-index sits at 215; Seattle's is 198. That gap reflects rent and home-price differences captured in the C2ER ACCRA quarterly survey. Groceries (Los Angeles 110 vs Seattle 113), transportation (132 vs 122), and utilities (121 vs 110) all contribute, but housing is the dominant factor.
They are tracked separately. The cost-of-living composite measures consumer prices; state income tax is a different axis. California and Washington 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.
