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 $6,186/mo in Chicago vs $6,066/mo in San Jose—roughly $120/mo less in San Jose before housing ($1,436/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 117 for Chicago and 178 for San Jose (100 = national average). The destination is about +52.1% 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 $152,137/yr gross in San Jose (~$12,678/mo), with estimated take-home around $8,612/mo. Versus estimated take-home in Chicago at the scenario gross, that is about +39.2% (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 $4,376/mo is left after rent in Chicago at the scenario gross vs $3,366/mo in San Jose at the same gross. At the equivalent gross in San Jose, about $5,912/mo after rent. Typical rent differs by about +$890/mo between the two cities in our data.
