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 $6,108/mo in Boston—roughly $78/mo less in Boston before housing ($930/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 117 for Chicago and 145 for Boston (100 = national average). The destination is about +23.9% 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 $123,932/yr gross in Boston (~$10,328/mo), with estimated take-home around $7,391/mo. Versus estimated take-home in Chicago at the scenario gross, that is about +19.5% (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 $3,328/mo in Boston at the same gross. At the equivalent gross in Boston, about $4,611/mo after rent. Typical rent differs by about +$970/mo between the two cities in our data.
