Can you live on $90k 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. $90,000 equals $43.27 an hour for a 40-hour week — $18.85 an hour above that line.
In Chicago, $90k is workable for one person, especially outside the most in-demand neighborhoods, but it is not a salary that makes big-city living effortless. 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.

How much can you save on $90,000 in Illinois?
Setting aside the 20% share — about $1,131 a month or $13,567 a year — would build a six-month emergency fund ($16,959, based on the 50% needs bucket) in about 15 months. Kept up for ten years at an assumed 5% annual return, those deposits would grow to roughly $175,559 — an illustration, not a forecast. Contributing to a 401(k) also lowers taxable income: each $1,000 put in pre-tax saves about $270 in federal and state income tax at this salary.

- 20% savings rate: $13,567/year
