Yet within these constraints, some manufacturers consistently achieve margins 10-15 percentage points above their competitors.
The difference comes down to operational excellence, pricing discipline, and product mix management. This guide provides benchmarks for different manufacturing sectors and actionable strategies for improving your margins.
Manufacturing Gross Margin Benchmarks
Manufacturing margins vary significantly by product type, complexity, and competitive positioning. Here's what "good" looks like across different sectors.
Commodity/High-Volume Manufacturing
(Metal stamping, injection molding, basic fabrication, commodity chemicals)
Below Average
<20%
Average
25-35%
Best-in-Class
40%+
Why these margins: Products are often interchangeable, forcing price competition. Margins depend on operational efficiency, automation level, and scale. Best-in-class commodity manufacturers win through superior productivity and cost control.
Specialty/Engineered Products
(Precision machining, specialty chemicals, engineered components, medical devices)
Below Average
<30%
Average
35-45%
Best-in-Class
50%+
Why these margins: Technical complexity, certifications, and customer switching costs create pricing power. Customers value quality, reliability, and application expertise over lowest price. Higher skill requirements limit competition.
Custom/Job Shop Manufacturing
(Custom fabrication, low-volume specialized production, prototype manufacturing)
Below Average
<35%
Average
40-50%
Best-in-Class
55%+
Why these margins: Customization commands premium pricing. Setup and engineering costs are amortized over small runs, requiring higher per-unit margins. Expertise and relationships matter more than scale.
Food & Beverage Manufacturing
Below Average
<25%
Average
28-38%
Best-in-Class
42%+
Why these margins: High material costs and commodity ingredient exposure compress margins. Differentiated/premium brands achieve better margins than private label. Yield management and spoilage control are critical.

Key Margin Drivers in Manufacturing
Manufacturing margins are driven by a complex interaction of factors. Understanding these helps prioritize improvement efforts.
Margin Builders
- • High capacity utilization (85%+)
- • Product differentiation/specialization
- • Strong supplier relationships
- • Low scrap and rework rates (<2%)
- • Appropriate automation level
- • Value-based pricing discipline
- • Product mix optimization
Margin Killers
- • Scrap, rework, and quality failures
- • Low capacity utilization
- • Material cost increases not passed through
- • Excessive setup time and changeovers
- • Poor inventory management
- • Unplanned downtime
- • Pricing to lowest bidder on commodity work
The Capacity Utilization Lever
In manufacturing, capacity utilization has enormous margin impact due to fixed overhead absorption. A plant running at 60% capacity must spread the same fixed costs over fewer units. Moving from 60% to 85% utilization can improve gross margin by 5-10 percentage points. However, utilization must be achieved with profitable orders—filling capacity with low-margin work doesn't help.
Strategies to Improve Manufacturing Margins
1. Reduce Material Costs
Materials typically represent 40-60% of manufacturing COGS, making this the largest cost reduction opportunity.
- Consolidate suppliers: Concentrate spend with fewer suppliers to gain volume leverage. Target 80% of spend with top 5-10 suppliers.
- Negotiate annually: Don't let contracts auto-renew. Competitive bidding and annual negotiations can yield 3-8% savings.
- Consider alternative materials: Engineering can often identify equivalent materials at lower cost. Value engineering saves margin.
- Reduce scrap and yield loss: Every piece of scrap is purchased material that generated no revenue. Track yield by product and process.
2. Improve Labor Productivity
- Track direct labor efficiency: Standard hours earned vs. actual hours worked. Best-in-class achieves 90%+ efficiency.
- Reduce setup and changeover time: SMED (Single-Minute Exchange of Die) techniques can cut changeovers by 50-90%.
- Cross-train operators: Flexibility reduces idle time when demand shifts between products.
- Automate strategically: For high-volume products, automation often pays back within 1-2 years through labor reduction and quality improvement.
3. Eliminate Quality Failures
- Track cost of quality: Scrap, rework, warranty, and customer returns. Most manufacturers underestimate these costs by 50%+.
- Root cause analysis: Every quality failure should trigger investigation. Recurring issues are margin leaks.
- Statistical process control: Catch quality drift before it produces scrap. Prevention is cheaper than detection.
- Supplier quality programs: Incoming material quality problems cascade through production. Hold suppliers accountable.
4. Optimize Product Mix
- Know margin by product: Many manufacturers are surprised to find some products lose money. Activity-based costing reveals true profitability.
- Steer sales toward profitable products: Sales incentives, pricing, and capacity allocation should favor high-margin products.
- Rationalize the portfolio: Low-margin, low-volume products often consume disproportionate resources. Consider eliminating or repricing.
- Develop higher-margin offerings: Innovation and premiumization can shift the mix toward better margins over time.
Red Flags: When Manufacturing Margins Are in Trouble
Warning Signs
- !Gross margin declining while revenue grows: Growing revenue with shrinking margins suggests pricing discipline problems or unfavorable mix shifts.
- !Capacity utilization below 70%: Under-absorbed overhead is crushing margins. Either fill capacity with profitable work or right-size the operation.
- !Scrap rates above 3-5%: Quality problems are destroying value. Investigate root causes immediately.
- !Material costs rising faster than prices: Failing to pass through cost increases erodes margins. Implement pricing discipline.
- !Labor efficiency below 80%: Significant direct labor is being wasted on non-value-added activities.
Tracking Manufacturing Margins
Effective margin management requires tracking at multiple levels and frequencies.
| Metric | Frequency | Target |
|---|---|---|
| Overall gross margin | Monthly | At or above industry benchmark |
| Gross margin by product line | Monthly | No product below minimum threshold |
| Material cost variance | Weekly | Within 2% of standard |
| Direct labor efficiency | Daily/Weekly | >90% |
| Scrap/rework rate | Daily | <2% |
| Capacity utilization | Weekly | >85% |
Standard Cost Systems
Effective margin management requires a standard cost system that tracks variances between expected and actual costs. Material price variances, material usage variances, labor rate variances, and labor efficiency variances should be tracked monthly and investigated when significant. Variance analysis turns margin management from reactive to proactive.
Frequently Asked Questions
What is a good gross margin for a manufacturing company?
Manufacturing gross margins typically range from 25-45%, varying significantly by sector. Commodity manufacturing (metal stamping, injection molding) averages 25-35%. Specialty/engineered products achieve 35-45%. Custom/complex manufacturing can reach 40-50%+. Your target depends on product complexity, automation level, and competitive positioning.
How do I calculate manufacturing gross margin?
Manufacturing gross margin = (Revenue - COGS) / Revenue × 100. COGS should include direct materials, direct labor, and manufacturing overhead (facility costs, equipment depreciation, utilities, quality control for production). It should NOT include SG&A, R&D, or corporate overhead—those are operating expenses.
Why do manufacturing margins vary so much by sector?
Margins reflect the value-add and competitive dynamics of each sector. Commodity products face price competition and thin margins. Specialty products with technical complexity, certification requirements, or customization can charge premiums. Capital intensity, material costs as % of sales, and automation levels also drive differences.
How does automation affect manufacturing gross margins?
Automation typically improves gross margins by reducing direct labor costs and improving quality (less scrap/rework). However, benefits depend on production volume—automation has high fixed costs that must be spread across enough units. For high-volume commodity products, automation is essential for competitive margins.
What's the biggest margin killer in manufacturing?
Scrap, rework, and quality failures are often the biggest margin destroyers—they waste materials, consume labor without revenue, and delay shipments. A 5% scrap rate on a 35% gross margin product consumes 14% of your margin. Quality improvement often has the highest ROI of any margin initiative.
How should I handle material cost increases?
Material costs should be passed through to customers, but timing and communication matter. Build escalation clauses into contracts for volatile materials. Communicate increases with advance notice and data. Bundle price increases with value-adds where possible. Don't absorb cost increases hoping they'll reverse—they rarely do.
What's the relationship between volume and margin in manufacturing?
Fixed costs (overhead) create margin leverage—higher volume spreads fixed costs across more units, improving gross margin per unit. This is why capacity utilization matters so much. Running at 60% capacity vs. 85% can swing margins by 5-10 percentage points. However, avoid chasing volume with unprofitable pricing.
How do I improve margins without losing customers?
Focus on the controllables: material cost reduction through supplier consolidation, productivity improvements, quality/scrap reduction, and product mix optimization. Price increases should be strategic—test elasticity, segment customers, and communicate value. Often the best margin gains come from operational improvements, not pricing.
