Crime Scene Cleaner pay in Illinois, bottom to top
BLS has no figure for crime scene cleaners. These are its numbers for hazardous materials removal workers, the closest group, which includes decontamination workers along with asbestos and lead abatement crews. Treat them as a rough guide, not a measure of crime scene work itself.
| Pay level | Hourly | Yearly | National hourly |
|---|---|---|---|
| 10th percentile | $21.15 | $43,990 | $18.49 |
| 25th percentile | $23.81 | $49,530 | $21.50 |
| Median | $29.49 | $61,330 | $23.78 |
| 75th percentile | $36.48 | $75,880 | $29.58 |
| 90th percentile | $47.58 | $98,970 | $39.62 |
| Average (mean) | $31.49 | $65,490 | $27.13 |
From the bottom tenth ($21.15) to the top tenth ($47.58), the top of the scale pays about 2.2 times the bottom in Illinois, close to the 2.1 times spread for crime scene cleaners nationwide.
Both ends of the scale beat the national figures: $21.15 against $18.49 at the bottom tenth, and $47.58 against $39.62 at the top.
The average, $31.49, is close to the median, so pay sits fairly evenly around the middle.

What a biohazard cleaning business in Illinois should charge
Higher wages in Illinois go straight into the price. Take a biohazard cleaning business in Illinois paying the state median of $29.49 and run it through the labor rate calculator with its starting numbers (40-hour weeks, 10 paid days off, 2 unbilled hours a day, 7.65% payroll taxes, $90,000 a year of overhead and 15% profit).
| Step | Math | Result |
|---|---|---|
| Paid hours | 40 × 52 | 2,080 |
| Hours at work | 2,080 − 10 days × 8 | 2,000 |
| Billable hours | 2,000 × 6 ÷ 8 | 1,500 |
| Labor cost | $29.49 × 2,080 × 1.0765 | $66,032 |
| Break-even rate | ($66,032 + $90,000) ÷ 1,500 | $104.02 |
| Rate with 15% profit | $104.02 ÷ 0.85 | $122.38 |
That is $122.38 per billable hour, 4.1 times the wage, and $10.03 more than the $112.35 the same math gives at the national median wage.
Paying the 75th percentile instead, $36.48 in Illinois, to hire and keep experienced people raises the rate to $134.65.
A cheaper crew saves less than it seems: at the 25th percentile wage of $23.81, the rate only drops to $112.40.
Overhead, at $60 of every billed hour, and the unbilled hours move this rate more than a raise does. A dollar more in wages adds about $1.76 to the rate.
