Snapshot: how to read this move ($100,000 scenario)

  • Monthly take-home at the same gross. At $100,000/year, estimated take-home is about $6,598/mo in Sioux Falls vs $6,547/mo in Seattle—roughly $51/mo less in Seattle before housing ($615/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 90 for Sioux Falls and 142 for Seattle (100 = national average). The destination is about +57.8% more expensive than the origin for that basket—then state/province and payroll taxes shift take-home further.

  • Equivalent salary to keep the same lifestyle. To match purchasing power after COL, the model suggests about $157,778/yr gross in Seattle (~$13,148/mo), with estimated take-home around $9,845/mo. Versus estimated take-home in Sioux Falls at the scenario gross, that is about +49.2% (by design, equivalent gross targets similar real spending power after COL and taxes; exact match varies with rounding).

  • Cash after typical 1BR rent (illustrative). Using average 1-bedroom rent in the housing table, roughly $5,698/mo is left after rent in Sioux Falls at the scenario gross vs $4,497/mo in Seattle at the same gross. At the equivalent gross in Seattle, about $7,795/mo after rent. Typical rent differs by about +$1,150/mo between the two cities in our data.
