Crime Scene Cleaner pay in Maryland, 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 | $21.92 | $45,590 | $18.49 |
| 25th percentile | $22.47 | $46,730 | $21.50 |
| Median | $23.39 | $48,640 | $23.78 |
| 75th percentile | $27.10 | $56,360 | $29.58 |
| 90th percentile | $36.14 | $75,180 | $39.62 |
| Average (mean) | $25.58 | $53,210 | $27.13 |
Pay is bunched up in Maryland. The top tenth earn $36.14 an hour or more, about 1.6 times the $21.92 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.
The floor is higher than nationally ($21.92 against $18.49) but the ceiling is lower ($36.14 against $39.62), which squeezes pay toward the middle.
The average wage, $25.58, sits 9% 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 Maryland should charge
Say you run a biohazard cleaning business in Maryland and pay the state median of $23.39 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 | $23.39 × 2,080 × 1.0765 | $52,373 |
| Break-even rate | ($52,373 + $90,000) ÷ 1,500 | $94.92 |
| Rate with 15% profit | $94.92 ÷ 0.85 | $111.67 |
That is $111.67 per billable hour, 4.8 times the wage, and almost the same as the $112.35 the same math gives at the national median wage.
Paying the 75th percentile instead, $27.10 in Maryland, to hire and keep experienced people raises the rate to $118.18.
A cheaper crew saves less than it seems: at the 25th percentile wage of $22.47, the rate only drops to $110.05.
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.
