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 $6,052/mo in Washington—roughly $281/mo less in Washington before housing ($3,379/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 85 for Charleston and 135 for Washington (100 = national average). The destination is about +58.8% 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 $158,824/yr gross in Washington (~$13,235/mo), with estimated take-home around $9,022/mo. Versus estimated take-home in Charleston at the scenario gross, that is about +42.5% (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 $5,513/mo is left after rent in Charleston at the scenario gross vs $3,852/mo in Washington at the same gross.
