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 $6,108/mo in Boston—roughly $235/mo less in Boston before housing ($2,810/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 106 for Philadelphia and 145 for Boston (100 = national average). The destination is about +36.8% 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 $136,792/yr gross in Boston (~$11,399/mo), with estimated take-home around $8,060/mo. Versus estimated take-home in Philadelphia at the scenario gross, that is about +27.1% (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 $3,328/mo in Boston at the same gross. At the equivalent gross in Boston, about $5,280/mo after rent. Typical rent differs by about +$1,230/mo between the two cities in our data.
