← Biohazard cleanup bid calculator
Less than the scene's size decides, and more than "day rate plus a per-pound hazmat fee" captures. Two costs move the price on their own terms — regulated waste billed per whole container, and PPE billed per decon cycle — and both are worked out below with this calculator's own verified numbers.
A licensed regulated-waste hauler charges per container picked up, not per pound. On this calculator's defaults, a 40-pound-capacity container costs $110 to have hauled — whether it holds 40 pounds or 4. A small scene generating just 15 pounds of waste still needs one whole container, so its disposal line is $110.00, not the $41.25 a linear per-pound rate ($110 / 40 lb × 15 lb) would suggest. That gap is about 167% of the naive figure, and it does not shrink for a small job — it grows, because a small job has less other cost to absorb it.
| Biohazard waste | Containers needed | Disposal cost |
|---|---|---|
| 15 lb | 1 | $110.00 |
| 55 lb (default) | 2 | $220.00 |
| 155 lb | 4 | $440.00 |
155 lb happens to divide evenly into 40-lb containers with room to spare, so its disposal cost is exactly double the 55-lb job's. That is a coincidence of the numbers, not a rule — a waste estimate that lands just past a container boundary (41 lb, or 121 lb) pays for a whole extra container's worth of capacity nobody uses. Estimate waste generously rather than exactly on a boundary, because rounding only ever runs one direction: up.
Used PPE cannot be re-donned, so a technician who leaves the contaminated area for a break, to run equipment out, or across a shift change needs a fresh set to go back in. On this calculator's defaults, a 2-technician crew at one decon cycle each needs 2 PPE sets ($76.00 total). The same crew at two decon cycles each — one break, say — needs 4 sets ($152.00), exactly double, because PPE scales with re-entries, not headcount. A per-head PPE estimate misses that entire second cycle.
This is arithmetic on the rates and estimates you type. It does not know your regulated-waste hauler's actual per-container price, your state or OSHA bloodborne-pathogen decon requirements, or whether a job is billable to insurance. Replace every default with your own hauler invoice and PPE order before quoting.
Price your own job nowOn this calculator's own verified defaults (2 technicians, 5 hours each, 55 lb of regulated waste), a job prices around $1,374.67 — direct cost $1,031.00 plus a 25% target margin. A smaller scene (1 technician, 2 hours, 15 lb of waste) still prices around $697.33, mostly because disposal and PPE do not shrink in proportion to the scene.
Because regulated-waste disposal is billed per whole container, not per pound. A 15-pound job still needs one 40-pound-capacity container at the full per-container price ($110 on this calculator's defaults) — the same charge a 40-pound job would pay — so a per-pound estimate ($41.25 for 15 lb) undercounts a small job by a much larger percentage than a large one.
On this calculator's defaults, raising decon cycles from 1 to 2 per technician (a break, an equipment run, or a shift change that forces re-entry) raises PPE cost from $76.00 to $152.00 for the same 2-technician crew — $76.00 more, because PPE is priced per re-entry, not per head, and used PPE cannot be re-donned.
Not exactly. Raising waste from 55 lb to 155 lb on this calculator's defaults raises disposal from $220.00 (2 containers) to $440.00 (4 containers) — exactly double, because 155 lb happens to need exactly double the containers. A waste estimate that lands just over a container boundary, rather than exactly on one, pays for a whole extra container's worth of unused capacity.
