Seattle vs Denver: What the Numbers Say
Denver is the cheaper of the two, at a cost-of-living index of 128 versus 172 for Seattle. On our model's $5,000 national-average monthly budget, that works out to about $2,200 more per month (34% more) in Seattle. The largest single gap is housing, at roughly $1,089 per month.
On state income tax alone (single filer, our bracket data): at $75,000 you would owe $3,300 in Colorado versus $0 in Washington; at $150,000 it is $6,600 versus $0.
Break-even: a $100,000 salary in Denver leaves about $74,780 a year after federal, state, and FICA tax. To keep the same purchasing power in Seattle, you would need about $100,486 after tax, which means a gross salary near $130,534. This assumes a single filer taking the standard deduction and uses one index for all spending, so treat it as a starting point, not a quote.
