Housing is the single biggest driver of cost-of-living differences between metros. In Boston, MA, the median household typically spends 35–45% of gross income on housing — significantly above the 28% "affordable" threshold most lenders use.

State tax plays a meaningful but smaller role. Massachusetts levies a state income tax of approximately 5%, which reduces take-home by roughly $8,550 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 $150,104. This excludes federal income tax, which varies by filing status and deductions.
