Profitability is one of the most misunderstood metrics in construction. Many contractors focus on revenue growth, but high revenue does not guarantee healthy profit — or positive cash flow.
So what is a good profitability percentage for a construction business?
The answer depends on gross profit vs net profit, job type, and how well the business is managed.
Gross Profit vs Net Profit (This Matters)
Before talking percentages, it’s critical to understand the difference:
Gross Profit = Revenue − Direct job costs (labor, materials, subs)
Net Profit = What’s left after all expenses (overhead, admin, insurance, interest, taxes, etc.)
Many construction businesses look profitable at the gross level but struggle at the net level.
What Is a Good Gross Profit Margin in Construction?
A healthy gross profit margin for most construction businesses typically falls between:
20%–35% gross profit
General guidelines:
Residential remodeling: 30%–35%
General contractors: 20%–30%
Specialty trades: 25%–40% (depending on labor intensity)
Commercial construction: 15%–25%
If your gross margin is consistently below 20%, it becomes very difficult to cover overhead and still produce net profit.
What Is a Good Net Profit Margin in Construction?
Net profit margins are much thinner than gross margins.
A good net profit margin for a construction business is typically:
5%–10% net profit
Benchmarks:
1%–3% → Survival mode
3%–5% → Stable but vulnerable
5%–10% → Healthy, sustainable
10%+ → Exceptionally well-run business
Many construction companies operate at 2%–4% net profit, which leaves little room for errors, delays, or cost overruns.
Why Construction Margins Are Often Lower Than Expected
Construction profitability is impacted by:
Inaccurate job costing
Change orders not billed or collected
Labor overruns
Rising material costs
Retainage delaying cash
Poor overhead control
Without strong financial systems, profit erodes quickly.
Profitability by Construction Type (General Ranges)
Type of Construction | Gross Margin | Net Margin |
Residential Remodeling | 30–35% | 7–12% |
General Contracting | 20–30% | 5–8% |
Specialty Trades | 25–40% | 8–15% |
Commercial Construction | 15–25% | 3–6% |
These are averages — strong operators can outperform these ranges.
Why Net Profit Alone Is Not Enough
A construction business can be “profitable” and still struggle financially.
Common issues include:
Profits tied up in retainage
Cash flow timing mismatches
Profitable jobs funding unprofitable ones
Owners underpaying or overpaying themselves
This is why job-level profitability and cash flow forecasting matter as much as margins.
How a CFO Improves Construction Profitability
From a CFO perspective, improving profitability focuses on:
Accurate job costing by project
Real-time margin tracking
Overhead allocation
Pricing based on true costs
Cash flow planning around retainage
Most margin improvement comes from better controls, not just higher prices.
Signs Your Construction Business Has a Profitability Problem
You may have a margin issue if:
Revenue is growing but cash is tight
Jobs “look profitable” but money disappears
You can’t clearly explain job margins
One bad project wipes out a good year
These are structural issues — not effort issues.
A “good” profitability percentage for a construction business depends on your job mix and discipline, but net profit under 5% is risky and gross margins below 20% are unsustainable long-term.
Healthy construction companies focus on:
Strong gross margins
Controlled overhead
Accurate job costing
Predictable cash flow
Profit is not luck — it’s structure.
Frequently Asked Questions About Construction Profitability
What is a healthy profit margin for a construction business?
A healthy construction business typically targets 20%–35% gross profit and 5%–10% net profit. Gross profit covers job costs, while net profit reflects what remains after all overhead and expenses.
What is considered low profit in construction?
Net profit below 3% is considered low and risky in construction. At this level, even small cost overruns, delays, or material increases can eliminate profitability entirely.
Why do construction companies have thin profit margins?
Construction margins are thin due to:
Labor and material cost volatility
Job overruns and unbilled change orders
Retainage delaying cash collection
Inaccurate job costing
High overhead relative to revenue
Without strong controls, profits erode quickly.
Is 10% net profit realistic in construction?
Yes, but it usually requires:
Accurate job costing
Strong pricing discipline
Tight overhead control
Consistent change order management
Many well-run specialty trades and remodelers achieve 8%–12% net profit.
How can a construction business increase profitability?
Construction profitability improves by:
Tracking job costs in real time
Pricing jobs based on true costs
Billing and collecting change orders promptly
Controlling overhead
Improving cash flow planning around retainage
Raising prices alone is rarely enough.
Is gross profit or net profit more important?
Both matter, but gross profit is the foundation.If gross margins are too low, no amount of overhead control will produce healthy net profit.
Can a construction business be profitable but still struggle with cash?
Yes. This is very common. Profits may be tied up in:
Retainage
Work in progress
Slow customer payments
That’s why cash flow forecasting is just as important as profitability tracking.
What gross margin should contractors aim for?
General targets:
Residential remodeling: 30%–35%
General contractors: 20%–30%
Specialty trades: 25%–40%
Commercial construction: 15%–25%
Margins below these ranges usually signal pricing or cost control issues.
When should a construction company get CFO help?
CFO-level support is often needed when:
Revenue exceeds $1M annually
Jobs vary widely in profitability
Cash flow feels unpredictable
One bad job can wipe out profits
A CFO helps turn job data into strategic decisions.
What is the biggest mistake contractors make with profitability?
The biggest mistake is not knowing true job costs.Without accurate job costing, contractors may win work that looks profitable but actually loses money.
