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 $6,547/mo in Seattle vs $6,199/mo in Billings—roughly $348/mo less in Billings before housing ($4,174/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 142 for Seattle and 95 for Billings (100 = national average). The destination is about -33.1% 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 $66,901/yr gross in Billings (~$5,575/mo), with estimated take-home around $4,415/mo. Versus estimated take-home in Seattle at the scenario gross, that is about -32.6% (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 $4,497/mo is left after rent in Seattle at the scenario gross vs $5,249/mo in Billings at the same gross. At the equivalent gross in Billings, about $3,465/mo after rent. Typical rent differs by about $1,100/mo between the two cities in our data.
