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 $6,232/mo in Denver vs $6,598/mo in Sioux Falls—roughly +$366/mo more in Sioux Falls before housing ($4,400/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 110 for Denver and 90 for Sioux Falls (100 = national average). The destination is about -18.2% less 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 $81,818/yr gross in Sioux Falls (~$6,818/mo), with estimated take-home around $5,532/mo. Versus estimated take-home in Denver at the scenario gross, that is about -11.2% (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 $4,482/mo is left after rent in Denver at the scenario gross vs $5,698/mo in Sioux Falls at the same gross.
