Where tile and stone contractors lose money
4 things cost tile and stone contractors money without ever becoming a line item, and each one traces to a step you can install.

The CFOS target at that size is 24.5% gross margin, 13% overhead and 11.5% net, and the 3.5 points left on the table is where those mechanisms live. Figures for all 7 revenue bands are in the table below.
Tile and stone ranks 1st 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 figures CFMA, Jones Maresca and other sources publish by trade and size, and they are before tax figures. Net profit starts from gross margin less overhead and is then adjusted for taxes and a few other expenses, so it is stated after taxes. It is published as its own average and is not calculated from the other two on the page.
CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business. CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. Read a net profit figure here against CFMA's with that difference in mind.
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, so read those bands as a model and not as a survey result.

4 problems specific to tile and stone
One purchase order has to cover the entire floor, and it gets placed before the GC has a slab. Crew is mobilized, the container is on site, and the floor reads 3/16 in 10 feet. Bid 4,200 square feet, buy seven pallets, and the difference stays in the warehouse until somebody hauls it off. The GC compressed the schedule and wants more men on the floor, but the floor is set and waiting on grout.
Each one below points at the item, the unit, the clock, or the party that makes it a tile and stone problem, and it says which step fixes it.
| Mechanism | Why it's specific to this trade | Step |
|---|---|---|
| The Dye Lot Forces You To Buy The Whole Job Up Front | A plumber buys fixtures in phases and nothing about the third order looks different from the first, so he can pace his buying against his cash. Tile has no phase option, because the material is the job's appearance, so the buy is all at once and it happens months ahead of installation. Natural stone tightens it further: a slab bundle comes off a single block, the vein match dies with that block, and a distributor holds the bundle only 7-30 days without a deposit of roughly 50%. | Job cost structure |
| Setting Over A Bad Slab Means You Just Bought It | Three conditions gate tile and none of them are yours. Flatness belongs to the concrete sub, while permanent HVAC and the calendar belong to the GC. ASTM F2170 in-situ RH probes can't go in until the slab has been at service temperature and humidity for 48 hours, then need 24 hours to equilibrate, and your setting materials have a 50 degree minimum that has to hold through cure. No other finish trade has its warranty, its start date, and its callback exposure all keyed to conditions somebody else controls. | Project management |
| The Leftover Pallet Is Margin You Already Spent | Most trades sell and buy in units close enough that the estimate and the purchase order can be compared line for line. Tile sells in square feet and buys in pallets and whole slabs, and it loses material to layout, tile size, and block yield in ways one blended waste percentage can't describe. Using a single waste factor across a straight lay restroom and a herringbone lobby guarantees the estimate and the purchase order drift apart job by job, and nothing at month end closes that loop. | Estimating system |
| Ten Guys Can't Beat A 24 Hour Cure | Every other trade recovers schedule with bodies. A framer doubles the crew and the wall goes up twice as fast; tile goes at the speed of chemistry whether one man or ten is on the slab. So tile is the trade that can't answer a compressed schedule with manpower, and it's also the trade whose scope gets fractured into separate trips by the sequence of everybody else's work. | Estimating system |

It averages 22% at $1M to $5M and 29% at $500M+, as a percentage of revenue. That is 2.3 points above the interiors and finishes average of 19.7%. The CFOS target at $1M to $5M is 24.5%. 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 tile and stone contractor have?
Tile and stone shares its net profit figure with 12 other trades at this revenue, which is what the published data resolves to. It averages 8% at $1M to $5M and 21% at $500M+, after taxes, as a percentage of revenue. That is 1.7 points above the interiors and finishes average of 6.3%. The CFOS target at $1M to $5M is 11.5%. The CFOS target recalculates at your revenue: 10 percent after taxes, or 3.5 points better than your trade's industry average, whichever is higher.
What profit margin should a small tile and stone business have?
Owners usually mean net profit when they say profit margin, and for tile and stone at $1M to $5M that's 8%. Gross margin is a different number, 22%, and it's what's left after job costs but before overhead. Overhead is the 14% between the two. A small tile and stone business holding 8% net is at the published figure for its size, and the CFOS target at that revenue is 11.5%.
Does tile and stone get more profitable as it grows?
Overhead is the number that moves. Tile and stone sheds 6 points between $1M to $5M and $500M+, which is in line with the 5.3 points interiors and finishes sheds as a group. Net profit is already above the 48-trade average, so the room is in holding it while revenue rises.
