Salary & Tax CalculatorSeattle's cost of living index of roughly 143 puts it among the priciest large metros in the country, and the story is almost entirely about housing supply failing to keep pace with tech-sector job growth. Amazon and Microsoft alone have added tens of thousands of high-paying jobs over the past decade, while the metro's geography — hemmed in by Puget Sound, Lake Washington, and surrounding hills — makes it genuinely difficult to build enough new housing to match demand. Median home prices in Seattle proper run well above $800,000, and even outlying suburbs across the 520 and I-90 floating bridges carry a real premium. One partial offset: Washington is one of only nine states with no personal income tax, so a worker relocating from a high-tax state keeps more of each paycheck than the sticker-price cost of living gap alone would suggest. Commuting typically means some combination of the Link light rail, buses, and notoriously congested highways, with ferries factoring in for many suburban and island commuters.
🏙️ Understanding the Index
How this calculator converts a salary or price between cities.
How it Works
Cost of living indexes score cities against a US average of 100 by weighting housing, groceries, utilities, transportation, and healthcare. A score of 143 means costs run about 43% above average.
The Formula
Equivalent Amount = Other City Amount × (Seattle Index ÷ Other City Index). At the default index of 100, $70,000 elsewhere needs about $100,100 in Seattle to buy the same lifestyle.
Pro Tip
Factor in Washington's zero state income tax when comparing job offers — it can meaningfully narrow the effective gap versus a high-tax state even at Seattle's elevated cost of living.
Frequently Asked Questions
What is Seattle's cost of living index? +
Seattle has a cost of living index of roughly 143, meaning everyday expenses run about 43% higher than the US national average of 100. Housing is by far the largest contributor, with home prices and rents pushed up by strong tech-sector demand.
Why is Seattle so expensive? +
Seattle's cost of living is driven mainly by housing scarcity relative to job growth. Amazon, Microsoft, and a large tech and biotech sector have concentrated high-paying jobs in a geographically constrained metro hemmed in by water and mountains, which limits how much new housing supply can be built and keeps prices elevated.
Does Seattle have a state income tax? +
No. Washington is one of nine US states with no personal income tax, which offsets some of the high cost of living. Someone relocating from a high-income-tax state may find their take-home pay stretches further than the raw cost of living index alone suggests.
How do Seattle residents commute? +
Seattle relies on a mix of light rail (Link), buses, and a growing number of bridges and floating highways across Lake Washington, plus a well-known reliance on ferries for some suburban commuters. Traffic congestion is a real cost in time even for those who avoid car ownership.
How accurate is this cost of living calculator? +
This tool uses a composite index that blends housing, groceries, utilities, transportation, and healthcare costs. It is a directional estimate, not a precise budgeting tool. Actual costs vary by neighborhood, lifestyle, and household size, so treat the output as a starting point rather than a guarantee.
