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 $6,157/mo in Boise vs $6,390/mo in Phoenix—roughly +$233/mo more in Phoenix before housing ($2,800/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 102 for Boise and 107 for Phoenix (100 = national average). The destination is about +4.9% 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 $104,902/yr gross in Phoenix (~$8,742/mo), with estimated take-home around $6,667/mo. Versus estimated take-home in Boise at the scenario gross, that is about +8.3% (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 $4,877/mo is left after rent in Boise at the scenario gross vs $4,970/mo in Phoenix at the same gross. At the equivalent gross in Phoenix, about $5,247/mo after rent. Typical rent differs by about +$140/mo between the two cities in our data.
