Crime Scene Cleaner pay in Wisconsin, 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 | $18.70 | $38,890 | $18.49 |
| 25th percentile | $21.79 | $45,330 | $21.50 |
| Median | $22.96 | $47,750 | $23.78 |
| 75th percentile | $29.42 | $61,190 | $29.58 |
| 90th percentile | $37.27 | $77,530 | $39.62 |
| Average (mean) | $25.68 | $53,410 | $27.13 |
From the bottom tenth ($18.70) to the top tenth ($37.27), the top of the scale pays about 2 times the bottom in Wisconsin, close to the 2.1 times spread for crime scene cleaners nationwide.
The floor is higher than nationally ($18.70 against $18.49) but the ceiling is lower ($37.27 against $39.62), which squeezes pay toward the middle.
The average wage, $25.68, sits 12% above the median. A smaller group of higher earners pulls the average up, so the median is the better guide to what a typical crime scene cleaner makes.

What a biohazard cleaning business in Wisconsin should charge
Say you run a biohazard cleaning business in Wisconsin and pay the state median of $22.96 an hour. Here is the labor rate calculator's math on 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 | $22.96 × 2,080 × 1.0765 | $51,410 |
| Break-even rate | ($51,410 + $90,000) ÷ 1,500 | $94.27 |
| Rate with 15% profit | $94.27 ÷ 0.85 | $110.91 |
That is $110.91 per billable hour, 4.8 times the wage, and $1.44 less than the $112.35 the same math gives at the national median wage.
Paying the 75th percentile instead, $29.42 in Wisconsin, to hire and keep experienced people raises the rate to $122.25.
A cheaper crew saves less than it seems: at the 25th percentile wage of $21.79, the rate only drops to $108.86.
At this wage, overhead is most of the price: $60 of every billed hour goes to it before anyone is paid. Spreading the same overhead over more billable hours, with a second person or less drive time, brings the rate down fastest.
