Diagnostic Medical Sonographer Salary in Illinois: Pay by Experience, City & Take-Home

A diagnostic medical sonographer in Illinois earns a median salary of $100,660 a year, which works out to about $48.40 an hour, according to the U.S. Bureau of Labor Statistics (2025). Most sonographers in the state land between $78,350 at the low end and $122,680 at the top. That median sits comfortably above the national figure, and Chicago pushes it higher still.

How Illinois pay compares to the national average

Illinois pays sonographers well. The state median of $100,660 runs $4,070 above the national median of $96,590 reported by the BLS for 2025. That’s a real edge, and it holds up across the pay scale because a single dense metro, Chicago, anchors most of the state’s employment.

The spread tells you more than the midpoint. The bottom 10 percent of Illinois sonographers earn $78,350, while the top 10 percent clear $122,680. The 25th percentile sits at $85,230 and the 75th at $107,330. So even a sonographer near the bottom of the Illinois range is earning close to a comfortable middle-class wage, and the ceiling is high enough that experience and the right employer matter a lot to where you land.

The state employs about 3,270 diagnostic medical sonographers. That is a meaningful workforce concentrated heavily in and around Chicago, which means most of the hiring, and most of the highest-paying jobs, sit in one corner of the state. If you live downstate, the numbers still beat the national floor, but the very top of the range is harder to reach without commuting toward a major hospital system.

Sonographer pay in Illinois by experience

BLS data doesn’t track years on the job directly, but the percentile bands are the closest honest proxy you’ll find. New sonographers and those in lower-cost parts of the state tend to cluster near the 10th and 25th percentiles, while experienced techs with specialty credentials and seniority at a big hospital system push toward the 75th and 90th. Here’s how the Illinois range breaks down.

The jump from entry to median is the steepest part of the curve. An entry-level sonographer at $78,350 who reaches the median is looking at $22,310 more a year, a gain of roughly 28 percent. After that, the climb flattens. Moving from median to the 75th percentile adds $6,670, and going from the 75th to the 90th adds another $15,350. The lesson for a new tech is simple: the first three to five years, plus the credentials you earn in them, do most of the heavy lifting on your pay.

Where you sit in that table depends on a few things you can actually control. Specialty registries (vascular, echocardiography, abdominal, OB/GYN) move you up. So does landing at a large academic or hospital system rather than a small outpatient clinic, working in a department that runs nights, weekends, or call, and being willing to cross-train so you can cover more than one modality. A sonographer who can scan both echo and vascular is worth more to a staffing manager than one who can only do general abdominal work.

It helps to read the percentile gaps as dollars rather than ranks. The distance from the 10th percentile to the 25th is $6,880. From the 25th to the median it’s $15,430. From the median to the 75th it’s $6,670, and from the 75th to the 90th it’s $15,350. The two biggest jumps, both around $15,000, happen as you move from early career into the solid middle, and again as you move from experienced into senior or specialized work. Those are the two moments where a new credential or a department change tends to pay for itself fastest. The middle of the curve, from the 25th to the 75th, is flatter, which is why a sonographer who plateaus at a single clinic without adding registries can stall for years inside that band.

It’s also worth being honest about what the entry figure means in Illinois. At $78,350, the state’s 10th percentile is already higher than the median pay for plenty of allied-health roles, so even a brand-new sonographer here is in a strong position. The reason the floor is so high is the same reason the state median beats the national one: Chicago’s large hospital systems set a high local baseline, and that baseline drags up the bottom of the range even outside the city. The flip side is that the lowest-paying jobs in the state are still mostly decent jobs, so the real money question is less about avoiding the floor and more about how quickly you can climb toward the $107,330 and $122,680 figures at the top.

Sonographer salary by Illinois metro

Geography is the single biggest swing factor inside the state. The Chicago area both employs the most sonographers and pays the most, and the gap between Chicago and the smaller downstate metros is wide enough to matter when you’re weighing a job offer or a move.

Chicago leads at $103,080, which is $2,420 above the statewide median and $10,990 above Peoria, the lowest-paying metro on this list at $92,090. Chicago also dominates on volume: its 2,280 sonographers make up roughly 70 percent of the entire state’s 3,270 jobs. If you want the most openings and the highest typical pay, the Chicago corridor is where both live.

Champaign-Urbana is the quiet surprise at $100,420, nearly matching the state median despite being a small market with about 100 sonographers. That’s the university-and-hospital effect of a college town with a teaching hospital. Springfield ($98,470) and Rockford ($95,020) sit in the middle, both anchored by regional hospital systems. Peoria’s $92,090 is the floor here, but remember the cost of housing in Peoria is a fraction of what it is in the Chicago suburbs, so the lower headline number can still buy more day to day.

One practical note: these are metro medians, not ceilings. A senior vascular tech in Peoria can still out-earn an entry-level generalist in Chicago. Use the metro figures to calibrate your expectations, then let your credentials and experience set where you actually land within the band.

The volume numbers are as useful as the pay numbers when you’re planning a job search. Chicago’s 2,280 positions mean openings turn over constantly, so there’s almost always something to apply to, and competing offers are realistic enough to give you bargaining power on pay. The downstate metros tell a different story. Peoria (170 sonographers), Springfield (120), Rockford (110), and Champaign-Urbana (100) are small enough that you might wait for the right role to open, and a single large employer often sets the local rate. That concentration cuts both ways: less competition for jobs once you’re established, but fewer fallback options if your employer freezes hiring.

Compare the extremes and the geography premium is clear. Chicago’s $103,080 against Peoria’s $92,090 is a $10,990 spread on the same job title in the same state. That’s roughly an 11 percent raise just for changing metros. But before you chase it, weigh the housing math. Chicago suburb rents and Cook County property taxes can erase a five-figure raise quickly, while $92,090 stretches a long way in Peoria. The headline median is only half the equation, which is exactly why the take-home and housing section below matters so much.

Take-home pay after taxes in Illinois

Your gross salary is not what hits your bank account. Illinois levies a flat state income tax, and federal income tax plus FICA (Social Security and Medicare) come out before you ever see a paycheck. The table below runs the four percentile points through 2026 tax assumptions for a single filer so you can see what actually lands.

At the median, a sonographer grossing $100,660 keeps $74,218 after federal, FICA, and Illinois state tax, an effective tax rate of 26.3 percent. That’s $6,185 a month. The entry-level tech keeps $59,627 (a 23.9 percent effective rate), and the senior sonographer at the 90th percentile nets $88,532, with the effective rate creeping up to 27.8 percent as more income falls into higher federal brackets.

Look at how the bite grows as you climb. The entry-level sonographer loses $18,723 of a $78,350 gross to taxes. The median earner loses $26,442 of $100,660. The experienced tech at the 75th percentile loses $28,751 of $107,330 and nets $78,580, while the senior earner loses $34,148 of $122,680. That rising effective rate, from 23.9 percent at entry to 27.8 percent at the top, is normal progressivity in the federal brackets; Illinois itself charges a flat rate, so the state line moves in near-lockstep with gross pay. State tax runs $3,878 at entry, $4,983 at the median, $5,313 at the 75th percentile, and $6,073 at the 90th. The practical read: each extra dollar you earn near the top is taxed harder than the dollars below it, so a raise from $107,330 to $122,680 feels smaller in your bank account than the $15,350 gross gap suggests.

FICA is the steadiest line on the table. Social Security and Medicare take $5,994 at entry, $7,700 at the median, $8,211 at the 75th percentile, and $9,385 at the 90th, climbing in proportion to pay since sonographer salaries stay under the Social Security wage cap. It’s the one deduction you can’t credential or negotiate your way out of, so it’s worth budgeting around as a fixed share of every paycheck.

The cross-state reality check. Illinois taxes income at a flat rate, and that costs you against a no-income-tax state. Take the same median sonographer. In Illinois they net $74,218. In Texas, where there is no state income tax, the equivalent net is $79,200. That’s a gap of $4,982 a year that Illinois keeps and Texas does not. Put plainly, a Texas sonographer at the same gross pay takes home $4,982 more, purely because of state tax.

Before you book a moving truck, the number that actually matters is net pay minus local housing, not net pay alone. Chicago-area rents and property taxes are high, and a Texas metro might hand back that $4,982 in cheaper housing, or eat it in something else. Run your own offer through the Illinois paycheck calculator and then subtract what you’ll really spend on rent or a mortgage where the job is.

How to earn more as a sonographer in Illinois

The pay table shows there’s real room to climb, from $78,350 at the entry floor to $122,680 at the senior ceiling. Here’s how Illinois sonographers actually close that gap.

• Stack ARDMS specialty registries. Credentials in echocardiography (RDCS), vascular (RVT), or OB/GYN and abdominal (RDMS) make you eligible for higher-paying departments. Cross-credentialed techs who can cover two modalities are the ones who reach the 75th and 90th percentiles.
• Target the Chicago corridor. At a $103,080 median, the Chicago-Naperville-Elgin metro pays more and hires far more than any other part of the state. Even a reverse commute from the suburbs into a large hospital system can lift your base meaningfully.
• Move toward a large hospital or academic system. Teaching hospitals and big health networks tend to pay above outpatient clinics, offer shift differentials for nights and weekends, and have clearer ladders to lead-sonographer roles.
• Take call and off-shifts. Differential pay for nights, weekends, and on-call is one of the fastest ways to push your effective hourly above the $48.40 median without changing jobs.
• Build toward lead or supervisory roles. Moving into a lead sonographer, modality coordinator, or imaging supervisor position is where the 90th-percentile $122,680 figures tend to live.
• Keep formal learning current. Continuing education and a relevant associate-to-bachelor’s bridge can open supervisory and educator tracks. Platforms like Coursera offer healthcare and imaging coursework you can stack alongside clinical CE.

Job outlook for sonographers in Illinois

Illinois currently employs about 3,270 diagnostic medical sonographers, with the clear majority, roughly 2,280, working in the Chicago metro. Sonography nationally is one of the faster-growing healthcare-imaging occupations, driven by an aging population that needs more cardiac, vascular, and abdominal imaging, and by the steady shift of diagnostic work into lower-cost outpatient settings.

For someone weighing the field in Illinois, the takeaway is that demand is concentrated where the pay is highest. The Chicago corridor offers the most positions and the strongest medians, while downstate markets like Peoria, Springfield, Rockford, and Champaign-Urbana hire in smaller but steady numbers around their regional hospitals. To see what’s open near you right now, scanning a board like ZipRecruiter by metro and modality is the fastest way to gauge live demand and pay.

Related and higher-paying roles in Illinois

If you’re comparing imaging and nursing tracks in Illinois, here’s how the closest roles stack up against the sonographer median of $100,660, using BLS 2025 figures for the same state. Both common comparison roles actually pay less than sonography here, which is part of why the credential is worth earning.

A radiologic technologist in Illinois earns a median of $79,930, which is $20,730 less than a sonographer in Illinois. A registered nurse in Illinois earns a median of $95,990, which is $4,670 less than a sonographer in Illinois. So the sonography credential carries a clear pay premium over both the general rad-tech role and staff nursing in this state.
