What this pays, and what it is worth
- Illinois sits in the middle of the pack for this job. The median is $59,860, ranking 26 of 51 states with figures. Close enough to the national middle that where you live matters more than the headline suggests.
- Middle of the local pack. Of 494 occupations Illinois reports figures for, this is number 273.
- Prices here sit close to the national average, so the adjustment changes little. From $59,860 the take-home is $47,459, which is worth about $48,009 in comparable money. Tax does most of the work here, not cost of living. The average is higher, $63,630, because the best-paid pull it up.
- Illinois occupies the middle band for computer user support specialists: a median of $59,860, ranking 26 of 51. Where nominal pay is close to the national figure, the tax and price adjustments below carry proportionally more weight in determining the real outcome.
- In Illinois's occupational distribution, computer user support specialists sits at 273 of 494 — neither quartile. This local position is what a resident compares against, and it is determined by the state's own labor market rather than by national patterns for this occupation.
- Illinois's price level is near the national average, so price deflation is close to neutral for computer user support specialists on its $59,860 median: $47,459 retained after tax becomes $48,009 in national-average terms. Where the price adjustment is small, the tax stack is the dominant determinant of the real outcome. The mean of $63,630 sits above the median, the right skew typical of wage data.

Sources and assumptions
- A median is the middle, not an offer. Half of computer user support specialists in Illinois earn under $59,860 and half over. The published range runs $40,440 at the tenth percentile to $96,040 at the ninetieth. Experience and employer move an individual a long way inside that.
- That $47,459 take-home in Illinois comes from $59,860. It is the no-frills case: single filer, standard deduction, nothing set aside before tax. Real circumstances almost always reduce the tax. City and school-district taxes are not counted at all. Locally the work ranks 273 of 494.
- Two cautions on $48,009, the adjusted value of that $59,860 median. It levels out prices with a single number for all of Illinois. No actual address matches that. The wage figures and price figures are also from different years. Each is published on its own timetable. This work sits at 273 of 494 locally.
- Figures are distribution medians for computer user support specialists in Illinois, not entry or offer rates. The published band runs $40,440 to $96,040; within-state dispersion of that width routinely exceeds the dispersion between states, so tenure, employer and metropolitan area predict an individual's pay better than geography does.
- Retained pay of $47,459, from $59,860, assumes a single Illinois filer with the standard deduction and no elective deferrals. Pre-tax retirement or HSA contributions, dependants and itemized deductions all reduce it further; local income taxes, excluded here, would increase it in the states that levy them. This occupation ranks 273 of 494 locally, and the state ranks 26 of 51 for it.
- This $48,009 adjusted figure, worked from $59,860, rests on a state-level price parity averaging over within-state dispersion larger than much of the between-state dispersion. Wage and price vintages differ by publication schedule. The result is directionally sound and not address-specific, for work at 273 of 494 in the state. The occupation ranks 273 of 494 locally.
Questions people ask
Is this the average pay for the job?
It is the midpoint, not the average. The average here is $63,630, dragged up by high earners; the middle figure describes a typical worker better.
Why is the pay range for this job so wide?
The label is broader than the work. From $40,440 at the bottom tenth to $96,040 at the top, the same title covers roles that share little beyond a name.
What does this pay actually buy where I live?
Further than the number implies. Illinois is cheaper than the national average, so this take-home behaves like $48,009 in national terms.
Where does the difference between the wage and my paycheck go?
Three of them are federal and one is not. After income tax, Social Security, Medicare and Illinois's own levy, $47,459 remains.
Can I compare this job across every state?
Yes for this one. Pay is published in all 51 jurisdictions, so a state-to-state comparison here rests on the same survey everywhere rather than on a patchwork.
How does the published median differ from the mean for this occupation?
The median is the midpoint of the distribution; the mean for this occupation in Illinois is $63,630. Wage distributions are right-skewed, so the mean exceeds the median wherever a minority earn substantially more. BLS publishes both because substituting one for the other misstates a typical worker's pay.
What drives the percentile dispersion in this occupation?
Dispersion between the tenth percentile ($40,440) and the ninetieth ($96,040) exceeds the family median dispersion. SOC codes aggregate roles differing in seniority, industry and specialisation, and BLS does not disaggregate below the detailed occupation level, so within-title variance is not separable from the published series.
What is this occupation's price-adjusted compensation in this state?
Illinois's regional price parity is at or below the national average, so nominal wages understate purchasing power. Take-home deflated by the state price level is $48,009 in national-average terms. The adjustment uses an all-items index and does not isolate housing.
What accounts for the gap between gross wage and take-home here?
Take-home of $47,459 reflects federal income tax, OASDI, Medicare and Illinois income tax for a single filer with no adjustments. The state layer is levied in addition to the federal one; only its rate and base differ between states.
Is this occupation's state coverage complete?
State-level estimates are published for all 51 jurisdictions for this occupation, so cross-state comparison is not confounded by suppression. ⚠️ Estimates remain survey-based and carry sampling error; small differences between adjacent states should not be over-read.
