FIBER GROSS MARGIN BENCHMARKS.
Fiber contractors average about 22% gross margin at $1M to $5M, rising to roughly 23% at $5M to $10M. The CFOS target at $1M to $5M is 24.5%, set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. The distance between the average and the target is almost always overhead that was never loaded into the rate.
In fiber the two and a half points between the trade average and the target are the per-unit cost history nobody keeps, and two and a half points is $25,000 on a $1M year and $125,000 on a $5M year. The work sells per foot placed, per splice, and per home connected, so the only cost report worth reading is crew-per-mile against those same units, split by aerial and underground. Bucket crews lashing to poles and a directional drill missing a sewer lateral are two different economies sold under one master service agreement. Until the cost system uses the contract's own units, a per-foot price is a guess dressed as a bid.
How to calculate: Gross margin is Revenue minus Direct Job Costs, divided by Revenue, times 100. Direct job costs include labour, materials, equipment and subcontracted work tied to the job. Not shop overhead, office staff or G and A.

| METRIC | INDUSTRY AVERAGE | CFOS TARGET | AT $10M TO $25M | NOTES |
|---|---|---|---|---|
| Gross Margin ($1M to $5M) | 22% | 24.5% | 24% | Industry figure rises to 23% at $5M to $10M and 24% at $10M to $25M. |
| Overhead Rate ($1M to $5M) | 15% | 14% | 13% | Falls to 13% by $10M to $25M as fixed cost spreads over more revenue. |
| Days Sales Outstanding | 90 days | 45 days | 30 days | Ninety days is weak, 45 is the target, 30 is strong. Nothing else moves cash faster. |
Industry figures are the AVERAGE for the trade at each revenue band, from the Run On CFOS Trade Benchmark Reference, not a floor. Net profit is stated after taxes. The CFOS target is what we build toward. The third column is what companies at $10M to $25M average, shown for direction of travel; that is a larger company, which is a different thing from a better managed one.
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. The bands above the $10M to $25M band are published at runoncfos.com as a modeled extension of the same curves. They have not been reconciled against the licensed CFMA Benchmarker, so read them as a model and not as a survey result.
Trade figures are from the Run On CFOS Trade Benchmark Reference, published by Sulphur Prairie Operations, LLC. Net profit is stated after taxes. CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business. Re-validate against CFMA reporting on the normal quarterly cycle, per the benchmark reference's own instruction.
The reference itself is published at fiber gross margin at the source. The sourcing note behind the 48 trade set is set out at runoncfos.com.
