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 $6,066/mo in San Francisco—roughly $277/mo less in San Francisco before housing ($3,316/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 106 for Philadelphia and 165 for San Francisco (100 = national average). The destination is about +55.7% 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 $155,660/yr gross in San Francisco (~$12,972/mo), with estimated take-home around $8,781/mo. Versus estimated take-home in Philadelphia at the scenario gross, that is about +38.4% (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 $2,516/mo in San Francisco at the same gross. At the equivalent gross in San Francisco, about $5,231/mo after rent. Typical rent differs by about +$2,000/mo between the two cities in our data.
