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 $6,547/mo in Seattle vs $6,066/mo in San Francisco—roughly $481/mo less in San Francisco before housing ($5,771/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 142 for Seattle and 165 for San Francisco (100 = national average). The destination is about +16.2% 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 $116,197/yr gross in San Francisco (~$9,683/mo), with estimated take-home around $6,873/mo. Versus estimated take-home in Seattle at the scenario gross, that is about +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 $4,497/mo is left after rent in Seattle at the scenario gross vs $2,516/mo in San Francisco at the same gross. At the equivalent gross in San Francisco, about $3,323/mo after rent. Typical rent differs by about +$1,500/mo between the two cities in our data.
