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 $6,066/mo in San Francisco vs $6,343/mo in Philadelphia—roughly +$277/mo more in Philadelphia before housing ($3,316/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 165 for San Francisco and 106 for Philadelphia (100 = national average). The destination is about -35.8% 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 $64,242/yr gross in Philadelphia (~$5,354/mo), with estimated take-home around $4,319/mo. Versus estimated take-home in San Francisco at the scenario gross, that is about -28.8% (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 $2,516/mo is left after rent in San Francisco at the scenario gross vs $4,793/mo in Philadelphia at the same gross. At the equivalent gross in Philadelphia, about $2,769/mo after rent. Typical rent differs by about $2,000/mo between the two cities in our data.
