CITY COMPARISON

Seattle vs Denver Cost of Living: Which Is Cheaper in 2026?

Data updated May 2026. Rent from Zillow ZORI, taxes from the Tax Foundation, cost-of-living index from BEA.

Seattle and Denver both pull remote workers and outdoorsy professionals, and the cost comparison is closer than most pairs. Washington has no state income tax. Colorado has a flat rate in the low single digits.

Seattle's edge is that zero income tax. Its drawback is a higher overall cost of living, pricier rent, and one of the steepest sales tax rates in the country. Denver counters with lower housing and a gentler sales tax.

Is Seattle or Denver cheaper to live in?

At a $100,000 salary, moving from Seattle to Denver frees up roughly $3,000 a year in disposable income. At a $150,000 salary the two cities come out about even.

It depends on income. At higher salaries Seattle's zero income tax outweighs its higher rent and sales tax. At moderate incomes Denver's cheaper housing and lower everyday costs usually win. Run your actual salary before deciding.

Who should pick Seattle?

Pick Seattle if you earn well into six figures, because that is where no state income tax turns into thousands of dollars that Denver's flat rate cannot match. You pay for it in rent and sales tax, but high earners come out ahead.

Who should pick Denver?

Choose Denver if your income is moderate or your priority is lower fixed costs. Cheaper rent and a lighter sales tax make the day-to-day math friendlier, and the income tax rate is low enough that it rarely swings the decision.

How we calculated this

Disposable income is gross salary minus federal income tax, state income tax, FICA, housing, everyday non-housing costs, and sales tax on discretionary spending. Federal tax uses 2026 effective rates after the standard deduction for a single filer. State income tax is a single-bracket approximation for mid-six-figure earners. Housing is the median 1-bedroom rent. Non-housing costs scale with the BEA cost-of-living index. Sales tax is applied to roughly 70 percent of discretionary spending, since groceries and many services are reduced-rate or exempt in most states.

The numbers on this page assume the same gross salary in both cities. That is the remote-work scenario, and it is the cleanest way to isolate the cost-of-living difference. If a new job would rebase your salary by city, plug both real offers into the tool below.
