What this pays, and what it is worth
- This is a good state for the work. Illinois pays this job a middle wage of $171,730, ranking 15 of 51 states and sitting about 1.95% above the national middle.
- Within Illinois this is well-paid work. Of 494 occupations with published figures in the state, this job ranks 5 — in the top quarter of everything people do there.
- Cost of living is unremarkable here. From $171,730, tax leaves $120,288, and adjusting for local prices barely moves it — about $121,681 in comparable terms. Averages run higher here, $179,190, since top earners drag the number up.
- Illinois's median for computer and information systems managers is $171,730, about 1.95% above the national figure and 15 of 51 states reporting. Whether that premium reaches the worker depends on the two adjustments below, which is the part a wage table cannot tell you.
- Ranked against every occupation Illinois publishes a median for, computer and information systems managers sits 5 of 494 — the upper quartile of the state's wage distribution. National standing and within-state standing are separate questions, and a job can occupy very different positions on each.
- Because Illinois sits close to the national price level, the real-terms figure for computer and information systems managers — median $171,730 — tracks the post-tax figure closely: $120,288 retained, $121,681 adjusted. ⚠️ Neither is a wage; the second describes what the first buys. Mean pay of $179,190 exceeds the median, so the upper tail is doing the work.

Sources and assumptions
- Treat $171,730 as a midpoint for Illinois, not a promise. The tenth percentile is $105,350 and the ninetieth is $273,500 — a wide band, and where you land in it depends on far more than the state.
- In Illinois the take-home figure of $120,288, from $171,730, assumes one filer, no dependants, and nothing paid into a pension before tax. Each of those lowers the bill, so treat it as the plain case. City and school-district income taxes are not included either, and in a few states those are real money. It ranks 5 of 494 occupations here.
- The wage data and the price data come from different years. That is how each is published. The price adjustment behind $121,681 uses one figure for the whole of Illinois. A city and a rural county there can differ by more than two states do. Out of 494 occupations the state publishes, this one sits at 5.
- The Illinois median of $171,730 describes the midpoint of a distribution spanning $105,350 to $273,500. Because that spread is typically larger than the interstate spread, a state median is a weak predictor for any individual worker in this occupation.
- Take-home for Illinois is computed for a single filer taking the standard deduction with no dependants and no pre-tax contributions, giving $120,288 from $171,730. Each omitted item reduces taxable income, so the figure is a lower bound on retained pay for this household shape. Municipal and school-district income taxes are excluded, which understates the burden materially in Ohio, Pennsylvania and Maryland. The occupation ranks 5 of 494 locally.
- Wage and price series carry different reference periods, each published on its own schedule. The real-terms figure of $121,681, worked from $171,730, deflates by a statewide parity that conceals substantial intra-state variation, concentrated in housing — so it supports comparison between states rather than the pricing of a move to a particular Illinois address, on work sitting at 5 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 $179,190, dragged up by high earners; the middle figure describes a typical worker better.
Why is the pay range for this job so wide?
Because one job title covers very different work. The bottom tenth here earn $105,350 and the top tenth $273,500 — experience, employer and specialism separate them, and a single figure hides all three.
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 $121,681 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, $120,288 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 $179,190. 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 ($105,350) and the ninetieth ($273,500) 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 $121,681 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 $120,288 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.
