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 $6,108/mo in Boston vs $6,204/mo in Birmingham—roughly +$96/mo more in Birmingham before housing ($1,145/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 145 for Boston and 85 for Birmingham (100 = national average). The destination is about -41.4% 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 $58,621/yr gross in Birmingham (~$4,885/mo), with estimated take-home around $3,885/mo. Versus estimated take-home in Boston at the scenario gross, that is about -36.4% (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 $3,328/mo is left after rent in Boston at the scenario gross vs $5,184/mo in Birmingham at the same gross. At the equivalent gross in Birmingham, about $2,865/mo after rent. Typical rent differs by about $1,760/mo between the two cities in our data.
