Can you live on $120k in Chicago?
Illinois taxes income at a flat 4.95%, and its property taxes are among the highest in the country. Housing costs are dominated by the Chicago area; downstate cities such as Peoria, Springfield and Champaign–Urbana are far cheaper.
MIT's Living Wage Calculator (data updated February 2026) puts the living wage for a single adult with no children in Illinois at $24.42 an hour, or $50,796 a year before tax. $120,000 equals $57.69 an hour for a 40-hour week — $33.27 an hour above that line.

Chicago is one of the more affordable of the very large U.S. metros: neighborhood choice (North Side lakefront vs. outlying neighborhoods or suburbs) matters more than anything else for a single earner's budget.
