What’s a good profit margin for a construction business?
Construction contractors average 8–15% net profit margin, according to CFMA industry data. A general contractor doing $1.2M/year in revenue at a 10% net margin takes home $120,000 — before separating owner’s compensation from profit.
Specialty subcontractors (electrical, plumbing, HVAC, concrete) tend to outperform general contractors on margin because they control a specific skill set that’s harder to commoditize and bid competitively.
The two costs that define construction margins
Materials are your largest variable cost — typically 40–55% of job revenue. Material cost overruns are the most common reason construction jobs go unprofitable. Accurate takeoffs and locked-in supplier pricing before bidding are non-negotiable for margin protection.
Labor runs 25–35% for most contractors. Unplanned overtime, crew idle time between jobs, and scope creep without change orders all compress labor margins quickly.
How construction companies lose margin
The biggest margin killer is change orders that aren’t billed. Work that falls outside the original scope should always be priced separately — otherwise you’re funding the client’s budget overruns with your profit. Contractors who consistently document and charge for changes outperform peers by 4–6 margin points, according to CFMA data.
Bid accuracy is the second lever: jobs won on aggressive pricing create margin pressure from day one that rarely recovers.
