Plumber Salary in Boston, MA

The headline median of $78,000 is only part of the picture. Boston, MA's cost of living index is 162 (US average = 100), meaning a dollar here buys roughly 62¢ of what it buys in an average US city.

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 $78,000 salary, that translates to roughly $31,200/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 $3,900 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 $68,468. This excludes federal income tax, which varies by filing status and deductions.
