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 $6,343/mo in Philadelphia vs $6,333/mo in Charleston—roughly $10/mo less in Charleston before housing ($111/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 106 for Philadelphia and 85 for Charleston (100 = national average). The destination is about -19.8% 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 $80,189/yr gross in Charleston (~$6,682/mo), with estimated take-home around $5,251/mo. Versus estimated take-home in Philadelphia at the scenario gross, that is about -17.2% (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 $4,793/mo is left after rent in Philadelphia at the scenario gross vs $5,513/mo in Charleston at the same gross.
