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 $6,249/mo in Columbia vs $6,108/mo in Boston—roughly $141/mo less in Boston before housing ($1,689/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 88 for Columbia and 145 for Boston (100 = national average). The destination is about +64.8% 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 $164,773/yr gross in Boston (~$13,731/mo), with estimated take-home around $9,517/mo. Versus estimated take-home in Columbia at the scenario gross, that is about +52.3% (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 $5,229/mo is left after rent in Columbia at the scenario gross vs $3,328/mo in Boston at the same gross. At the equivalent gross in Boston, about $6,737/mo after rent. Typical rent differs by about +$1,760/mo between the two cities in our data.
