5How to Weigh This Comparison
The $46,000 nominal pay gap between Pittsburgh, PA and Boston, MA is the wrong number to focus on in isolation. Cost-of-living indices of 90 and 162 mean the same paycheck stretches very differently in each market. The COL-adjusted figures above — $113,333 in Pittsburgh vs $91,358 in Boston— are the closest proxy for "how much will your money actually buy." A meaningful gap of $21,975 on that axis usually beats any nominal salary difference.
Housing is the single biggest driver of cost-of-living differences. In Boston, MA, expect housing to consume a larger share of gross income than in Pittsburgh, PA. If you're planning to rent, the COL index is a reasonable proxy for rent differences. If you're buying, expect purchase price differences to be sharper than the composite index suggests — housing tends to be the most inelastic component of cost of living.
Tax treatment matters but is usually smaller than COL impact. The 1.9% state tax rate difference (3.07% in Pennsylvania vs 5% in Massachusetts) translates to roughly $2,856 per year at these salary levels. States with no income tax (Texas, Florida, Washington, Nevada, Tennessee) often offset with higher property tax or sales tax, so factor in your housing and consumption patterns.
Career factors that don't show up in these numbers: total employment (with 4,000 positions in Pittsburgh vs 14,000 in Boston, the larger market offers more lateral moves and promotion paths), industry concentration (tech-heavy cities like San Francisco, Seattle, Austin pay premiums for engineering roles but may underpay other occupations), and 3–5 year career trajectory (year-over-year employment growth of 3.2% in Pittsburgh vs 4.5% in Boston reveals whether each market is expanding or contracting).
