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 $6,333/mo in Charleston vs $6,186/mo in Chicago—roughly $147/mo less in Chicago before housing ($1,769/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 85 for Charleston and 117 for Chicago (100 = national average). The destination is about +37.6% 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 $137,647/yr gross in Chicago (~$11,471/mo), with estimated take-home around $8,211/mo. Versus estimated take-home in Charleston at the scenario gross, that is about +29.7% (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 $5,513/mo is left after rent in Charleston at the scenario gross vs $4,376/mo in Chicago at the same gross. At the equivalent gross in Chicago, about $6,401/mo after rent. Typical rent differs by about +$990/mo between the two cities in our data.
