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. For a $155,000 salary, that translates to roughly $62,000/year on housing alone.

State tax plays a meaningful but smaller role. Massachusetts levies a state income tax of approximately 5%, which reduces take-home by roughly $7,750 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 $136,059. This excludes federal income tax, which varies by filing status and deductions.

If you're optimizing for purchasing power, compare the COL-adjusted column in the table above and pick the highest number. If you're optimizing for career progression, weight total employment and yearly growth in the role — larger markets offer more lateral moves and promotion velocity, even when nominal pay is lower.
