- 2024 Construction Financial Benchmarker, Executive Summary, Construction Financial Management Association, 2024. The survey puts gross profit margin at 21.8%, SG&A at 11.8%, and net income before taxes at 6.3% across all respondents. The best-in-class top quartile reaches 11.9% net income before taxes. Those figures are the whole-population reading, so a single trade can sit well either side of them.
- 2025 Performance Benchmarks, Construction Companies, Jones Maresca and Company, 2025. This study reports specialty contractor gross margin between 15% and 25%. It puts net profit at 5% to 8% for a well managed company, and total indirect cost between 8% and 15%. The indirect cost band is the one worth reading twice, because it's the number most owners have never calculated for their own shop.
- SPM Trade Benchmark Reference, Sulphur Prairie Operations LLC, 2026. The reference holds 48 trades, and net profit in it is stated before taxes. It publishes here as 47 trade pages, because landscaping and irrigation share an identical benchmark profile and are one market, so they're presented together. Everything else carries its own row.
How these figures were built. Gross margin and overhead come from CFMA's 2024 and 2025 financial survey data, plus a January 2026 specialty trade study. Net profit comes from a 48 trade master dataset that covers 24 served trades and 24 adjacent trades. The reference holds 48 trades and the site publishes 47 pages, because landscaping and irrigation carry the same figures and are the same market. Where the survey and the master disagree on net profit, the master carries it. Benchmarks are reviewed against each new CFMA survey release and reconciled before publication.

Why does overhead differ inside one group?

Does interiors and finishes get better as revenue grows?
Overhead does. Every trade in this group sheds overhead points as it moves up the 7 revenue bands, because the indirect cost base grows in steps while revenue grows continuously.

Overhead recalculates at every band, one point leaner than the trade average. Gross margin and net profit show the published $1M–$5M figure. Open any trade page in this group to see all three side by side.
