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 $6,186/mo in Naperville vs $6,249/mo in Columbia—roughly +$63/mo more in Columbia before housing ($759/yr annualized).

  • Cost of living vs taxes. Our benchmark COL index is 108 for Naperville and 88 for Columbia (100 = national average). The destination is about -18.5% 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 $81,481/yr gross in Columbia (~$6,790/mo), with estimated take-home around $5,256/mo. Versus estimated take-home in Naperville at the scenario gross, that is about -15% (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 $4,686/mo is left after rent in Naperville at the scenario gross vs $5,229/mo in Columbia at the same gross. At the equivalent gross in Columbia, about $4,236/mo after rent. Typical rent differs by about $480/mo between the two cities in our data.
