Crime Scene Cleaner pay in Missouri, 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 | $17.93 | $37,280 | $18.49 |
| 25th percentile | $20.00 | $41,590 | $21.50 |
| Median | $28.42 | $59,120 | $23.78 |
| 75th percentile | $32.61 | $67,840 | $29.58 |
| 90th percentile | $32.85 | $68,330 | $39.62 |
| Average (mean) | $26.44 | $54,990 | $27.13 |
Pay is bunched up in Missouri. The top tenth earn $32.85 an hour or more, about 1.8 times the $17.93 at the bottom tenth. Nationally that gap is 2.1 times, so the step from the bottom of the scale to the top is shorter here than in most places.
Both ends trail the national figures. The bottom tenth earn $0.56 an hour less than the bottom tenth nationally, and the top tenth $6.77 less than the national top tenth.
The average wage ($26.44) is a little under the median, so the low end of the range stretches further than the high end in Missouri.

What a biohazard cleaning business in Missouri should charge
Higher wages in Missouri go straight into the price. Take a biohazard cleaning business in Missouri paying the state median of $28.42 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 | $28.42 × 2,080 × 1.0765 | $63,636 |
| Break-even rate | ($63,636 + $90,000) ÷ 1,500 | $102.42 |
| Rate with 15% profit | $102.42 ÷ 0.85 | $120.50 |
That is $120.50 per billable hour, 4.2 times the wage, and $8.15 more than the $112.35 the same math gives at the national median wage.
Paying the 75th percentile instead, $32.61 in Missouri, to hire and keep experienced people raises the rate to $127.86.
A cheaper crew saves less than it seems: at the 25th percentile wage of $20.00, the rate only drops to $105.71.
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.
