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 $5,972/mo in Honolulu vs $6,547/mo in Seattle—roughly +$575/mo more in Seattle before housing ($6,899/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 182 for Honolulu and 142 for Seattle (100 = national average). The destination is about -22% 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 $78,022/yr gross in Seattle (~$6,502/mo), with estimated take-home around $5,270/mo. Versus estimated take-home in Honolulu at the scenario gross, that is about -11.8% (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 $3,922/mo is left after rent in Honolulu at the scenario gross vs $4,497/mo in Seattle at the same gross. At the equivalent gross in Seattle, about $3,220/mo after rent. Typical rent differs by about +$0/mo between the two cities in our data.
