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 Austin vs $6,157/mo in Boise—roughly $441/mo less in Boise before housing ($5,300/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 96 for Austin and 102 for Boise (100 = national average). The destination is about +6.3% 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 $106,250/yr gross in Boise (~$8,854/mo), with estimated take-home around $6,495/mo. Versus estimated take-home in Austin at the scenario gross, that is about -1.6% (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 $4,978/mo is left after rent in Austin at the scenario gross vs $4,877/mo in Boise at the same gross. At the equivalent gross in Boise, about $5,215/mo after rent. Typical rent differs by about $340/mo between the two cities in our data.

  • At $100,000 gross (Single filer), roughly $106,250 in Boise matches Austin purchasing power (+6.3% COL-adjusted).
  • Keeping the same $100,000 gross, estimated take-home shifts by about −$5,300/year (Austin → Boise) after federal, state, and FICA taxes.
