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 $6,598/mo in San Antonio vs $6,204/mo in Birmingham—roughly $394/mo less in Birmingham before housing ($4,735/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 88 for San Antonio and 85 for Birmingham (100 = national average). The destination is about -3.4% 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 $96,591/yr gross in Birmingham (~$8,049/mo), with estimated take-home around $6,018/mo. Versus estimated take-home in San Antonio at the scenario gross, that is about -8.8% (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 $5,418/mo is left after rent in San Antonio at the scenario gross vs $5,184/mo in Birmingham at the same gross. At the equivalent gross in Birmingham, about $4,998/mo after rent. Typical rent differs by about $160/mo between the two cities in our data.
