Housing is the single biggest driver of cost-of-living differences between metros. In Chicago, IL, housing costs fall closer to the national average of 25–30% of gross income, leaving more room in the budget for savings, transportation, and discretionary spending. For a $128,000 salary, that translates to roughly $35,840/year on housing alone.

State tax plays a meaningful but smaller role. Illinois levies a state income tax of approximately 4.95%, which reduces take-home by roughly $6,336 per year on this salary. States with zero income tax (Texas, Florida, Washington, Tennessee, Nevada) offer a structural advantage, but often offset it with higher sales tax or property tax. After state tax and approximate federal FICA (~7.6%), the estimated take-home is $112,418. This excludes federal income tax, which varies by filing status and deductions.
