What this pays, and what it is worth
- This is a good state for the work. Illinois pays biological technicians a middle wage of $55,790, ranking 15 of 51 states and sitting about 2.99% above the national middle.
- Middle of the local pack. Of 494 occupations Illinois reports figures for, this is number 297.
- Cost of living is unremarkable here. From $55,790, tax leaves $44,390, and adjusting for local prices barely moves it — about $44,905 in comparable terms. Averages run higher here, $56,790, since top earners drag the number up.
- Illinois's median for biological technicians is $55,790, about 2.99% 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.
- In Illinois's occupational distribution, biological technicians sits at 297 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.
- Because Illinois sits close to the national price level, the real-terms figure for biological technicians — median $55,790 — tracks the post-tax figure closely: $44,390 retained, $44,905 adjusted. ⚠️ Neither is a wage; the second describes what the first buys. Mean pay of $56,790 exceeds the median, so the upper tail is doing the work.

Sources and assumptions
- Treat $55,790 as a midpoint for Illinois, not a promise. The tenth percentile is $36,230 and the ninetieth is $79,440 — a wide band, and where you land in it depends on far more than the state.
- In Illinois the take-home figure of $44,390, from $55,790, 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 297 of 494 occupations here.
- One number stands for prices across all of Illinois, which is a simplification — big cities cost far more than small towns. Read $44,905, the adjusted value of that $55,790 median, as a way to compare states fairly, not as a quote for any particular place. The two datasets are also from different years. This job sits at 297 of 494 in the state.
- The Illinois median of $55,790 describes the midpoint of a distribution spanning $36,230 to $79,440. 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 $44,390 from $55,790. 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 297 of 494 locally.
- Price deflation uses one statewide parity for Illinois, so $44,905 — the adjusted value of that $55,790 median — establishes comparability between states rather than accuracy within one. The wage and parity series are dated independently, each following its own publication cycle, and neither is projected forward. This occupation sits at 297 of 494 locally.
Questions people ask
Why is the pay range for this job so wide?
The label is broader than the work. From $36,230 at the bottom tenth to $79,440 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 $44,905 in national terms.
Where does the difference between the wage and my paycheck go?
Into four separate taxes, not one. Federal income tax, Social Security and Medicare apply everywhere, and Illinois adds its own income tax on top — which is why $44,390 of this wage survives to your account.
Can I compare this job across every state?
This occupation is published everywhere — all 51 of them — so comparing states measures real differences rather than gaps in the data.
What drives the percentile dispersion in this occupation?
Dispersion between the tenth percentile ($36,230) and the ninetieth ($79,440) 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 $44,905 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 $44,390 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.
