A cost of living comparison using tax-adjusted purchasing power data.
Denver is meaningfully cheaper than Seattle — a 22% lower cost of living index makes a real difference. But there's a catch that doesn't show up in COL comparisons alone: Washington state has no income tax, and Colorado has a 4.4% flat income tax. The COL savings outweigh the new tax burden for most income levels, but the gap is smaller than it appears. On a $90,000 salary, keeping your Seattle income in Denver improves your purchasing power by roughly 22% — equivalent to earning about $110,000 in Seattle. The move makes financial sense, but it's not as dramatic as moving from a high-income-tax state.
| Category | Seattle | Denver | Difference |
|---|---|---|---|
| Overall COL Index | 162 | 127 | −22% |
| Median 1BR Rent | ~$2,100/mo | ~$1,800/mo | −14% |
| State Income Tax | 0% | 4.4% | +4.4 pp |
At $60,000: moving to Denver on the same salary gives you purchasing power equivalent to earning about $73,300 in Seattle — roughly 22% better. At $90,000: equivalent to approximately $110,000 in Seattle. The math works because Denver's overall price level is lower enough that even after paying Colorado's income tax, you come out ahead on what your money buys day to day.
The key variable: rent savings are significant but not enormous (14% lower in Denver than Seattle). Groceries, restaurants, and services tend to be cheaper in Denver as well. If you own a home and are comparing purchase prices, Denver has become expensive in absolute terms, but Seattle property prices are significantly higher.
Remote workers keeping their Seattle salary who want lower monthly costs and proximity to the Rockies. The outdoor recreation argument for Denver is strong — if you ski, hike, or mountain bike, being in Denver puts you 1-2 hours from world-class terrain in a way that Seattle (closer to the Cascades, but with less overall ski infrastructure) doesn't quite match.
People who need local employment should weigh this carefully. Seattle's tech job market is dominated by Amazon, Microsoft, and a dense startup ecosystem — it's one of the strongest tech hubs in the country. Denver has a solid job market but it's not a direct equivalent. If you're remote, this is irrelevant. If you need local work, research your specific field in Denver before making the move.
The climate trade is real and people have strong feelings about it. Seattle's famous gray winters — overcast and rainy from October through April — are genuinely draining for some people. Denver is famously sunny (over 300 days of sunshine annually), and even in winter you'll get stretches of 55°F days between snowstorms. The Denver summer is warmer and drier than Seattle's. Both cities have distinct advantages and committed advocates.
Denver is also generally more affordable in day-to-day spending beyond rent. Eating out, going to concerts, joining a gym — these things cost meaningfully less than in Seattle. The city has developed a real food and culture scene over the last decade, though it doesn't match Seattle's culinary reputation. Denver neighborhoods like Capitol Hill, LoHi, and RiNo have the kind of walkable, restaurant-dense character that makes cities feel like cities.
