Where precast concrete contractors lose money
4 things cost precast concrete contractors money without ever showing up as a line item, and each one traces to a step you can install. Precast concrete contractors average 22% gross margin, 15% overhead and 7% net profit at $1M–$5M of revenue. The CFOS target at that size is 24% gross margin, 14% overhead and 10% net, and the gap of 3 points on the bottom line is where those mechanisms live. Figures for all 7 revenue bands are in the table below.
Precast concrete sits 2nd of 5 in concrete and masonry on net profit, and it carries leaner overhead than the 48-trade average. Here is every figure, across all 7 revenue bands.

4 problems specific to precast concrete
Sixty grand of steel forms is sitting in the yard for a job that hasn't billed a dollar, and the piece count just got value engineered down after award. Drawings have sat on somebody else's desk for five weeks. Four hundred thousand dollars of panels are laying on dunnage, cast, cured, and piece marked, and none of it is billable this month. You go back for welding and drypack, then caulk a season later, then patch at punch, and the GC picks the week for every one of them.
Each one below points at the item, the unit, the clock, or the party that makes it a precast concrete problem, and it says which step fixes it.
| Mechanism | Why it's specific to this trade | Step |
|---|---|---|
| Your mold is a one-job asset you pay for up front | Every other trade's long lead item is something they install and get paid for as an installed unit. Precast's long lead item is tooling the job consumes, and at the end it goes on the scrap pile with the project's geometry still in it. That makes the form a job cost with a recovery schedule bolted to it, and when the schedule that recovery rides on changes, nobody outside your shop notices. | Equipment cost basis |
| The casting bed sits empty while the architect reviews | Idle bed time never gets charged to a job. There's no cost code for a reserved bed that cast nothing, so the plant burden and the crew you held for that slot get absorbed into overhead where it reads as a bad month with no cause attached. Other trades waiting on submittals are waiting to start work; a precast shop waiting on submittals is already paying for capacity it committed by date. | Project management |
| A yard full of panels the contract won't let you bill | For most subs, material sitting in a warehouse is a purchase waiting to be installed, and the supplier's terms carry it. For a precaster it's finished goods with your own labor and burden already cured into it, stamped with that project's piece marks so it can't be returned or moved to another job. The working capital hole is your own production cost laying on dunnage, and it grows every day the bed runs on schedule. | Job cost structure |
| Three more trips to that job after the crane goes home | Most subcontractors demobilize once and their cost curve ends there. A precaster's scope splits across four visits separated by months, and the last three carry full mobilization cost against line items that were bid as small change. That inversion is why the caulk trip loses money on nearly every job, and why nobody catches it: the cost hits long after anyone was still watching that job. | Project management |

What net profit should a precast concrete contractor run?

What profit margin should a small precast concrete business run?
Owners usually mean net profit when they say profit margin, and for precast concrete at $1M–$5M that's 7%. Gross margin is a different number, 22%, and it's what's left after job costs but before overhead. Overhead is the 15% sitting between the two. A small precast concrete business holding 7% net is at the published figure for its size, and the CFOS target at that revenue is 10%.
Does precast concrete get more profitable as it grows?
Overhead is the number that moves. Precast concrete sheds 6 points between $1M–$5M and $500M+, which is in line with the 6 points concrete and masonry sheds as a group. Net profit starts 0 points under the 48-trade average, so the room is in the overhead line before it's anywhere else.
