The percentiles on this page are observed metro figures for Mechanical Engineer in Chicago, IL, not a national median multiplied by a pay index. That matters: you are looking at how this labour market actually priced the role, including local industry mix. They are still estimates of the market — not a promise of what one employer will offer.
Among the 9 United States metros we can compare for this role, Chicago ranks 7 by median. Washington DC leads this comparison at $151,000 (+48% vs Chicago), while San Antonio sits at $92,800. Use those gaps to test a relocation thesis: a 15% cash raise that lands in a much more expensive metro can disappear in rent.
Chicago’s COL index (100) sits nearer the global baseline, so headline and adjusted pay are not far apart ($102,000 vs $102,000). Rent still matters: the 1-bedroom model is $1,650 / month, about 22% of take-home, with leftover near $3,870.

At 1.1× United States GDP per capita, this median is around a typical national living standard. Unemployment was about 4.2% in 2025. None of that is tax, immigration, or career advice — run the calculators and confirm rules officially.
How to read a mechanical engineer offer in Chicago
Start with gross cash, not the recruiting headline. If an offer lands near $102,000, you are in the lower half of this metro’s observed distribution; near $102,000 you are already paid like a stronger local hire. Then subtract a realistic tax path (simplified national effective rate here is about 13%, leaving $88,390 a year) and a housing number you would actually accept — not only the $1,650 model.
Because the 90th percentile is about 2.4× the 10th, two mechanical engineer jobs in Chicago can be different careers that share a title. Ask what sits in the package (bonus, overtime, equity, on-call) before you treat $102,000 as a fair target.
Demand and the mechanical engineer pipeline
Occupation-level employment for mechanical engineers is projected at about +10% over ten years. That is a national sketch of demand, not a forecast that Chicago will hire at that rate. Local openings still follow Chicago’s industry mix — hospitals, studios, public employers, or product companies — which is already baked into the observed percentiles more than into the outlook percentage.
