San Francisco and Seattle are the twin pillars of West Coast tech. Both have stunning natural beauty, progressive politics, coffee obsessions, and eye-popping housing costs. But between the two, Seattle is meaningfully cheaper — and the gap is larger than most people realize.
Overall: Seattle Is 13% Cheaper
San Francisco's cost-of-living index is 197.0 — nearly double the national average. Seattle is 172.0. That's a 13% difference overall, which on a $150,000 tech salary translates to roughly $11,700/year in savings.
Housing: Both Expensive, but SF Is in Another League
SF's housing index is an astronomical 376.0. Seattle's 290.0 is still brutal — but it's 23% cheaper than SF.
- Studio: $2,950/mo in SF vs $1,850/mo in Seattle (save $1,100/mo)
- 1-bedroom: $3,500/mo vs $2,100/mo (save $1,400/mo)
- 2-bedroom: $4,600/mo vs $2,700/mo (save $1,900/mo)
- 3-bedroom: $6,800/mo vs $3,800/mo (save $3,000/mo)
A 2-bedroom apartment savings of $1,900/month is $22,800/year. That's a down payment fund in just 2–3 years. See what you can afford with our mortgage calculator.
The Tax Bombshell: Washington Has No Income Tax
This is the single biggest financial difference between these cities. California's state income tax reaches up to 13.3%. Washington state has zero income tax.
On a $150,000 salary, that's roughly $10,000–$12,000/year more in your pocket in Seattle. On $200,000? Over $15,000. This alone can outweigh any cost-of-living comparison for high earners. Calculate your exact savings at TaxTakeHome.com.
Groceries and Transport
Groceries: SF 116.0, Seattle 108.0 — about 7% cheaper in Seattle, saving roughly $50/month.
Transportation: Both cities index at 158.0 (SF) and 139.0 (Seattle). Seattle's slightly cheaper here. Both have decent public transit for West Coast cities — SF's BART/Muni vs Seattle's Link Light Rail.
Utilities: Seattle Actually Wins Big
SF's utilities index is 82.0 while Seattle's is 88.0. Wait — SF is actually cheaper on utilities? Yes, partly because of California's mild climate and hydroelectric power. But the difference is small (~$25/mo).
Healthcare: SF Is Cheaper
SF's healthcare index (114.0) vs Seattle's (133.0) is one area where San Francisco genuinely costs less. Seattle's higher healthcare costs are driven by fewer provider options and higher insurance premiums in the Pacific Northwest.
Quality of Life Comparison
Seattle advantages:
- No state income tax (huge for high earners)
- 23% cheaper housing
- Less traffic congestion (slightly)
- Closer to outdoor recreation (mountains, skiing)
SF advantages:
- Better weather (less rain, milder)
- Lower healthcare costs
- More established tech ecosystem
- Better food and cultural diversity
For Tech Workers: The Math Is Clear
If you're a tech worker earning $150k+, Seattle saves you $20,000–$35,000/year between lower rent and zero state income tax. Many major tech companies (Amazon, Microsoft, Meta, Google) have significant Seattle/Bellevue offices. The financial case for Seattle is strong.
