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 $6,343/mo in Philadelphia—roughly +$157/mo more in Philadelphia before housing ($1,880/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 117 for Chicago and 106 for Philadelphia (100 = national average). The destination is about -9.4% 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 $90,598/yr gross in Philadelphia (~$7,550/mo), with estimated take-home around $5,815/mo. Versus estimated take-home in Chicago at the scenario gross, that is about -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 $4,376/mo is left after rent in Chicago at the scenario gross vs $4,793/mo in Philadelphia at the same gross. At the equivalent gross in Philadelphia, about $4,265/mo after rent. Typical rent differs by about $260/mo between the two cities in our data.
