What matters
- Nearly 25% of builders failed to generate a net profit in 2025, according to Buildertrend's 2026 construction statistics report, meaning one in four GCs worked full schedules and still lost ground financially.
- Average net margins for general contractors sit at just 5% to 6%, while top performers reach 10% to 12% through disciplined estimating and strategic job selection, according to CNBA's 2026 contractor margin analysis.
- The construction industry faces a projected shortage of 499,000 workers by 2026, according to Deloitte's 2026 Engineering and Construction Industry Outlook, which puts further pressure on labor costs and schedule reliability for GCs already operating on thin margins.
According to Buildertrend 2026, nearly 25% of builders failed to generate a net profit in 2025. That figure is not a slowdown story. The phones were ringing. The crews were busy. The problem was that revenue did not survive the trip from the invoice to the bank account.
Why Are So Many GCs Finishing the Year in the Red?
The short answer is that costs moved faster than bids. Material prices, subcontractor rates, and insurance premiums all climbed through 2024 and into 2025, but many contractors were still closing jobs based on estimates written months earlier. Fixed-price contracts that looked reasonable at bid time turned into margin destroyers by the time the work was done.
The problem compounds when you factor in change order discipline, or the lack of it. A lot of GCs absorb scope creep rather than document and bill for it. That habit is manageable when margins are fat. At 5% to 6%, a couple of underbilled change orders can wipe out the profit on an entire project.
There is also a cash flow dimension that does not show up in net margin figures. A contractor can finish a year technically profitable and still face serious operational stress if receivables are slow and payroll is weekly. Many of the builders who struggled in 2025 were not just losing money on paper. They were running short on cash mid-project.

What Separates 5% Margins from 10% Margins?
According to CNBA 2026, average net margins for general contractors sit at 5% to 6%, while top performers consistently reach 10% to 12%. That gap does not come from working harder or taking on more volume. It comes from a different approach to which jobs to take and how to price them.
Top-performing firms tend to share a few specific habits. First, they estimate with current costs, not historical averages. When lumber or steel prices shift, they reprice. Second, they build escalation clauses into contracts for projects that run longer than 90 days. Third, they track job costing in real time rather than waiting for a post-project accounting review to discover where the money went.
Job selection is equally important. High-margin GCs are willing to pass on work that does not pencil out, even when the pipeline looks thin. That discipline is difficult to maintain when the schedule is empty and a client is ready to sign. But accepting a money-losing job to keep crews busy rarely solves the underlying problem. It delays it.
The firms operating above 10% margins also tend to have tighter subcontractor agreements with defined cost escalation limits, and they maintain consistent documentation on scope so that change orders are billed promptly rather than absorbed.
How Does the Labor Shortage Feed the Margin Problem?
Labor is where the margin pressure gets structural. According to Deloitte's 2026 Engineering and Construction Industry Outlook, the industry faces a projected need for 499,000 new workers by 2026, with shortages expected to intensify. That is not a short-term hiring problem. It is a supply constraint that pushes subcontractor rates up and makes scheduling less predictable.
When a framing crew or an electrical sub is in high demand, they can charge more and deliver on their schedule, not yours. That creates two risks for a GC: higher direct costs and extended timelines that trigger overhead penalties or delay other jobs waiting in queue.
The contractors managing this best are building longer-term relationships with reliable subs, sometimes paying slightly above market to secure priority scheduling. The math on that trade-off often works. A sub who shows up on time and does clean work is worth more than a cheaper option who costs you two weeks of schedule slippage.

Why This Matters for General Contractors
The one-in-four failure rate is not a fluke or a bad year for a handful of underprepared operators. It reflects a structural margin problem that has been building for several years and that current cost conditions are accelerating. A contractor running at 5% net margin has almost no buffer for a problem job, a slow-paying client, or an unexpected material cost spike. Any one of those events, which are routine in construction, can push a project from barely profitable to a loss.
The firms pulling away from the pack are not doing anything exotic. They are estimating accurately, tracking costs in real time, billing change orders promptly, and being selective about which work they take. Reputation also plays a role in this picture. A strong review record and consistent online visibility allow top GCs to attract the clients who value quality over lowest bid, which is exactly the client base that supports healthier margins.
If your business finished 2025 in the red or with thinner margins than you expected, the data suggests the problem is almost certainly in the estimating and job-costing process, not in the volume of work you took on.
