Where flooring contractors lose money
5 things cost flooring contractors money without ever becoming a line item, and each one traces to a step you can install. Flooring contractors average 19% gross margin, 14% overhead and 5% net profit at $1M–$5M of revenue. The CFOS target at that size is 23% gross margin, 13% overhead and 10% net, and the 5 points left on the table is where those mechanisms live. Figures for all 7 revenue bands are in the table below.
Flooring ranks 5th of 6 in interiors and finishes on net profit, and it has leaner overhead than the 48-trade average. Here is every figure, across all 7 revenue bands.

Modeled extension of the survey curve, not reconciled against the licensed CFMA Benchmarker. That applies to the 4 bands above $10M to $25M, and no CFOS target is published for them.
Gross margin and overhead come from CFMA, Jones Maresca and SPM's own trade data, because those are the figures those sources report by trade and size. Net profit is calculated from them as gross margin minus overhead, so the three rows tie. That makes it an operating profit figure: what is left before interest, other income and expense, and the tax planning choices owners make, such as bonuses, depreciation methods and retirement contributions.
Surveys report net income before taxes after those items, so a reported net can run below the figure here. At the typical contractor the difference is small: CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. It grows with size. Against the separate measured net profit dataset, the calculated net runs 0.8 points higher at $1M to $5M, 2.2 points at $5M to $10M and 3.5 points at $10M to $25M, because the gross margin and overhead rows change faster with size than reported net profit does.
Above the $10M to $25M band the gross margin and overhead rows are a modeled extension of the same curves. They have not been reconciled against the licensed CFMA Benchmarker, and the calculated net there runs well above survey medians, so read those bands as a model and not as a survey result.

5 problems specific to flooring
The GC's schedule says flooring starts Monday. The designer is still holding samples, your carpet is a ten week mill run, and the certificate of occupancy date hasn't moved an inch. The mill wants a check before it ships, the GC won't pay for stored material, and your cash is stuck in a warehouse for four months waiting on a space that isn't ready. The floor bubbled a year after you left.
Each one below points at the item, the unit, the clock, or the party that makes it a flooring problem, and it says which step fixes it.
| Mechanism | Why it's specific to this trade | Step |
|---|---|---|
| The slab isn't dry and the mitigation bill is yours | Every trade deals with schedule compression. Flooring is the only one whose product is bonded to the slab with an adhesive that fails when the substrate is wet, and whose warranty is written by a mill that will pull your RH documentation before it honors anything. Drywall goes up over a wet slab all day long; an epoxy moisture vapor barrier is a scope item that exists only because your material is the one thing the concrete can ruin. | Project management |
| A ten week mill run can't absorb a late color pick | A late submittal costs most trades a few days of resequencing. It costs flooring the entire mill run, because the product doesn't exist yet and can't be bought locally at any price when the color is a custom dye lot. Being the last finish means there's nothing downstream left to compress except your own crew, which is why every week the designer holds samples comes back to you as premium time. | Project management |
| You bankroll the mill six months before you get paid | Most subs buy material roughly in step with the work, so cash out and cash in are weeks apart. Flooring buys the single largest cost on the job up front, because a dye lot can't be reordered in pieces, and then waits for the last finish slot in a 20 month schedule. You're running a financing operation at zero markup, and it scales with the size of the package you just won. | Monthly cadence |
| The mill replaces the tile. You replace the labor. | Most warranty callbacks are a punch item somebody fixes in a morning. A flooring failure is a system failure across a whole area, in a space that's now occupied, done at night, with furniture handling and no open job left in the system to charge it to. It comes back so long after closeout that it never posts to the job that created it, and the estimating side never learns which slabs and adhesives are burning you. | Overhead calculation |
| Paying by the yard without counting the yards | In an hourly trade, an overrun registers as hours against a budget and somebody notices by Friday. Paying per square foot or square yard turns labor into a purchased quantity, and a quantity is only wrong when somebody counts it, which in flooring almost never happens. The estimate already holds the correct number, so the check is right there. It never gets run. | Standards and accountability |
Flooring against the other 47 trades
| Metric | Flooring | Interiors and finishes average | All 48 average | Rank |
|---|---|---|---|---|
| Overhead | 14% | 13.3% | 15.1% | 6th of 48 |
| Gross margin | 19% | 19.7% | 22.1% | 41st of 48 |
| Net profit | 5% | 6.3% | 7% | 42nd of 48 |
Flooring sheds 6 points of overhead between $1M–$5M and $500M+, against 5.3 for interiors and finishes as a group. Inside that group, Acoustic ceiling, Tile and stone all keep 8%, the most in the group, and Acoustic ceiling, Drywall, Interiors and 1 more all run 13% overhead, the leanest. Flooring is neither, which is the usual position and the one with the most room in it.
Other interiors and finishes trades
What owners ask
What overhead should a flooring contractor run?
Flooring shares its overhead figure with 10 other trades at this revenue, which is what the published data resolves to. It averages 14% at $1M–$5M and 8% at $500M+, as a percentage of revenue. That is 0.7 points above the interiors and finishes average of 13.3%. The CFOS target at $1M–$5M is 13%. The CFOS target is one point leaner than your trade's industry average at your revenue.
What gross margin should a flooring contractor run?
Flooring shares its gross margin figure with 2 other trades at this revenue, which is what the published data resolves to. It averages 19% at $1M–$5M and 28% at $500M+, as a percentage of revenue. That is 0.7 points below the interiors and finishes average of 19.7%. The CFOS target at $1M–$5M is 23%. The CFOS target recalculates at your revenue: whatever gross margin produces the net profit target once overhead is paid, never below your trade's own industry average.
What net profit should a flooring contractor run?
Flooring shares its net profit figure with 2 other trades at this revenue, which is what the published data resolves to. It averages 5% at $1M–$5M and 20% at $500M+, before taxes, as a percentage of revenue. That is 1.3 points below the interiors and finishes average of 6.3%. The CFOS target at $1M–$5M is 10%. The CFOS target recalculates at your revenue: 10 percent before taxes, or 3.5 points better than your trade's industry average, whichever is higher.
What profit margin should a small flooring business run?
Owners usually mean net profit when they say profit margin, and for flooring at $1M–$5M that's 5%. Gross margin is a different number, 19%, and it's what's left after job costs but before overhead. Overhead is the 14% between the two. A small flooring business holding 5% net is at the published figure for its size, and the CFOS target at that revenue is 10%.
Does flooring get more profitable as it grows?
Overhead is the number that moves. Flooring sheds 6 points between $1M–$5M and $500M+, which is in line with the 5.3 points interiors and finishes sheds as a group. Net profit starts 2 points under the 48-trade average, so the room is in the overhead line before it's anywhere else.
Where does flooring rank against the other trades?
Flooring ties 1 trade in interiors and finishes on net profit, all at 5%. Acoustic ceiling, Tile and stone are the most profitable at 8%. Acoustic ceiling, Drywall, Interiors and 1 more run the leanest overhead at 13%. Gross margin ranks 41st of 48 and overhead ranks 6th.
