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 $6,052/mo in Washington vs $6,249/mo in Columbia—roughly +$197/mo more in Columbia before housing ($2,369/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 135 for Washington and 88 for Columbia (100 = national average). The destination is about -34.8% 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 $65,185/yr gross in Columbia (~$5,432/mo), with estimated take-home around $4,371/mo. Versus estimated take-home in Washington at the scenario gross, that is about -27.8% (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 $3,852/mo is left after rent in Washington at the scenario gross vs $5,229/mo in Columbia at the same gross. At the equivalent gross in Columbia, about $3,351/mo after rent. Typical rent differs by about $1,180/mo between the two cities in our data.
