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

  • Cost of living vs taxes. Our benchmark COL index is 135 for Washington and 95 for Billings (100 = national average). The destination is about -29.6% 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 $70,370/yr gross in Billings (~$5,864/mo), with estimated take-home around $4,602/mo. Versus estimated take-home in Washington at the scenario gross, that is about -24% (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 $3,852/mo is left after rent in Washington at the scenario gross vs $5,249/mo in Billings at the same gross.
