The co-packing versus self-manufacturing decision comes down to one question that most CPG founders get wrong: "Which option gives me better margins?" The real question is "Which option gives me better margins at my current volume, my projected volume in 18 months, and the level of operational complexity I can actually manage right now?"
Understanding the true cost of co-packing vs self-manufacturing margins requires looking beyond the per-unit price on a co-packer's quote. It means accounting for hidden costs on both sides, modeling break-even points, and being honest about what your team can handle. This analysis breaks down the real numbers.
The True Cost Structure of Co-Packing
A co-packer's quote looks simple: a per-unit price that covers raw materials, labor, packaging, and production overhead. A typical co-packing quote for a shelf-stable CPG product (think sauces, snacks, or dry mixes) runs $2.50 to $8.00 per unit depending on complexity, ingredients, and run size.
But the per-unit price on the quote is not your true COGS. Several additional costs sit on top of it.
Costs That Are Not on the Co-Packer's Quote
Minimum order quantities (MOQs). Most co-packers require minimum runs of 5,000 to 50,000 units per SKU. If you have four SKUs, a 10,000-unit minimum per SKU means tying up capital in 40,000 units of inventory. For a brand doing $200,000 in annual revenue, that is a significant cash commitment sitting in a warehouse.
Ingredient sourcing premiums. Some co-packers procure ingredients on your behalf and mark them up 10 to 30 percent. Others require you to source and ship ingredients to their facility, which adds freight costs and coordination overhead. Either way, the ingredient line on your COGS is higher than if you were buying direct at your own facility.
Changeover and setup fees. Every production run starts with a setup process: cleaning lines, calibrating equipment, running test batches. Co-packers charge $500 to $3,000 per changeover depending on the complexity of your product. If you run monthly production cycles across four SKUs, that is $24,000 to $144,000 annually in setup fees alone.
Warehousing and logistics. Your co-packer produces the product, but you still need to store it and ship it. Third-party warehousing costs $15 to $25 per pallet per month. If you are holding 60 pallets of inventory, that is $900 to $1,500 monthly before a single case ships.
Quality control costs. Reputable co-packers maintain food safety certifications and run in-line QC. But you still need to conduct your own incoming quality checks, shelf-life testing, and occasional on-site audits. Budget $5,000 to $15,000 annually for third-party lab testing and travel to your co-packer's facility.
Most founders calculate their co-packing COGS using only the per-unit price from the co-packer's quote. When you add MOQ capital costs, changeover fees, warehousing, freight to the co-packer, and quality testing, the true per-unit cost is typically 15 to 30 percent higher than the quoted price.
The True Cost Structure of Self-Manufacturing
Self-manufacturing looks cheaper on a per-unit basis once you reach a certain volume. But the upfront capital requirements and ongoing operational complexity are substantial. Founders who switch to self-manufacturing without modeling the full cost picture often discover that their "savings" disappeared into equipment payments, facility overhead, and hiring costs.
Fixed Costs You Take On
Facility lease and buildout. A food-grade manufacturing facility costs $8 to $20 per square foot annually in lease costs, depending on location. A 3,000-square-foot production space runs $24,000 to $60,000 per year in rent alone. Buildout costs (food-safe flooring, drainage, ventilation, electrical upgrades) add $50,000 to $200,000 upfront.
Equipment. Production equipment costs vary wildly by category. A basic bottling line for beverages runs $50,000 to $250,000. A snack packaging line with a multi-head weigher and bagger costs $75,000 to $300,000. Ovens, mixers, kettles, and specialty equipment add more. Plan for $100,000 to $500,000 in equipment for a modest production facility.
Certifications and compliance. SQF, BRC, or organic certifications cost $5,000 to $20,000 annually in audit fees. Local health department permits, fire inspections, and environmental compliance add another $2,000 to $10,000. You also need a food safety plan (HARPC under FSMA), which costs $3,000 to $8,000 to develop if you hire a consultant.
Insurance. Product liability, general liability, property insurance, and workers' comp for a small food manufacturing operation run $15,000 to $40,000 annually.
Variable Costs That Scale With Production
Labor. Production workers, a quality tech, and a production manager are your baseline team. Depending on your market, expect $35,000 to $50,000 per production worker and $60,000 to $85,000 for a production manager. A lean team of four to six people costs $180,000 to $350,000 annually in loaded labor costs.
Raw materials at direct pricing. This is where self-manufacturing shines. Buying ingredients direct from suppliers (rather than through a co-packer's markup) typically saves 10 to 25 percent on ingredient costs. At scale, this savings compounds significantly.
Utilities and consumables. Water, electricity, gas, and packaging consumables (labels, cartons, shrink wrap) add $2,000 to $8,000 monthly depending on production volume and process type.
Self-manufacturing has higher fixed costs and lower variable costs per unit. Co-packing has lower fixed costs and higher variable costs per unit. The break-even point where self-manufacturing becomes cheaper depends on your volume, your product complexity, and how efficiently you can run a production operation.
How to Calculate Your True Co-Packing COGS
Here is a practical framework for calculating the real per-unit cost of co-packing, not the number on the quote.
Step 1: Start with the quoted per-unit price. This is your base. Say it is $4.00 per unit.
Step 2: Add ingredient sourcing costs if applicable. If you source and ship ingredients to the co-packer, calculate the per-unit freight cost. If the co-packer sources ingredients, ask what markup they apply. Add $0.20 to $0.80 per unit.
Step 3: Amortize changeover fees across the run. If your changeover fee is $1,500 and your run is 10,000 units, that adds $0.15 per unit. Shorter runs make this number worse.
Step 4: Add warehousing costs per unit. If you hold inventory for an average of 60 days and your warehousing costs $0.10 per unit per month, add $0.20 per unit.
Step 5: Add freight from co-packer to warehouse. Per-unit freight costs vary, but $0.15 to $0.40 per unit is typical for domestic LTL shipments.
Step 6: Add QC and testing costs. Divide your annual testing budget by total annual units. For a brand producing 100,000 units annually with $10,000 in testing costs, that is $0.10 per unit.
Total true COGS in this example: $4.80 to $5.65 per unit versus the quoted $4.00. That is a 20 to 41 percent increase over the quote price.

Book a DemoWhen Co-Packing Makes Sense for Your Margins
Co-packing is the right choice for most brands in specific situations. The margin hit is real, but the operational simplicity and capital preservation can be worth it.
You are doing under $1 million in annual revenue. At this stage, the fixed costs of self-manufacturing will destroy your margins worse than co-packing premiums. A co-packer lets you focus capital on sales, marketing, and distribution rather than equipment and facilities.
You have fewer than three SKUs. A small SKU count means fewer changeovers and simpler production scheduling. Co-packers are most cost-effective when you are running large batches of a few products rather than short runs of many products.
Your product requires specialized equipment. If your product needs aseptic processing, retort packaging, freeze-drying, or another specialized process, the equipment costs make self-manufacturing prohibitive until you reach very high volume. Co-packers who already own this equipment amortize it across many clients.
You are testing new markets. Co-packing gives you the flexibility to produce smaller quantities as you test new retail channels, new geographies, or new product lines without committing to the infrastructure of self-manufacturing.
We ran the numbers on self-manufacturing three times before we finally made the switch. Each time, co-packing still made more sense at our volume. We did not cross the break-even point until we were consistently producing 300,000 units per quarter.
When Self-Manufacturing Improves Your Margins
The margin case for self-manufacturing gets stronger as volume increases and as you gain operational capability. Here are the signals that it is time to evaluate the switch.
Your annual production exceeds 500,000 to 1 million units. At this volume, the per-unit savings on ingredients, elimination of co-packer margins, and reduction in changeover fees start to outweigh the fixed costs of running your own facility. Run the actual numbers for your specific product before committing.
Changeover fees are eating your margins. If you have six or more SKUs and run monthly production cycles, changeover fees alone can add $0.50 or more per unit. Self-manufacturing eliminates this line item entirely.
You need faster iteration speed. Co-packers schedule production weeks or months in advance. If you need to adjust formulations, test new flavors, or respond to retailer requests quickly, owning your production gives you the agility that co-packing cannot.
Quality control is a constant battle. If you are spending significant time and money on QC issues at your co-packer (inconsistent fill weights, labeling errors, ingredient substitutions), bringing production in-house gives you direct control over every step.
A Simple Break-Even Framework
To determine your break-even point, calculate the monthly fixed cost of self-manufacturing (facility, equipment payments, insurance, base labor) and divide by the per-unit savings versus co-packing.
Example: If your monthly fixed costs for self-manufacturing are $25,000 and your per-unit savings versus co-packing are $1.00, you need to produce 25,000 units per month (300,000 annually) to break even. Every unit above that threshold generates $1.00 more margin than co-packing.
If your break-even volume is less than 80 percent of your current production volume, the switch makes financial sense. If it is above your current volume, stay with co-packing and revisit the analysis when you grow into it.
Model three scenarios when running your break-even analysis: conservative (current volume stays flat), moderate (20 percent annual growth), and aggressive (50 percent annual growth). The decision should be sound in at least two of the three scenarios before you commit capital to self-manufacturing.
How Co-Packing and Self-Manufacturing Affect Retail Margins
Your production model directly impacts your ability to hit the margin targets that retailers require. Most retailers expect a 35 to 50 percent gross margin on the products they carry. If your COGS is too high, you either price yourself out of the market or accept margins that make your business unsustainable.
Retail math example with co-packing. Your co-packing true COGS is $5.00 per unit. Your wholesale price needs to be at least $8.00 to give you a 37.5 percent gross margin. The retailer marks up to $12.00 (33 percent retailer margin). If comparable products retail at $9.99, you have a pricing problem that co-packing created.
The same product self-manufactured. Your self-manufacturing COGS is $3.50 per unit. Your wholesale price of $7.00 gives you a 50 percent gross margin. The retailer marks up to $10.49 (33 percent retailer margin). You are now competitively priced with healthy margins on both sides.
This is the margin analysis that matters most for retail expansion. If co-packing keeps your COGS so high that you cannot hit competitive retail price points while maintaining healthy wholesale margins, it becomes a growth bottleneck regardless of the operational convenience.

Book a DemoThe Hybrid Approach
Many successful CPG brands do not choose one or the other permanently. They run a hybrid model.
Co-pack your core SKUs, self-manufacture your specialty products. If you have two high-volume SKUs and four limited-edition or seasonal SKUs, co-pack the core products (where the co-packer's scale benefits you) and self-manufacture the specialty runs (where changeover fees and MOQs would make co-packing inefficient).
Co-pack now, build toward self-manufacturing. Use co-packing to preserve capital while you grow. Once you hit your break-even volume consistently for two or more quarters, invest in your own facility. This staged approach reduces risk and lets you learn production operations gradually rather than all at once.
Self-manufacture your hero product, co-pack line extensions. If one product drives 60 percent of your revenue, self-manufacturing that product captures the most margin improvement. Co-pack the remaining SKUs until they individually justify the switchover.
The co-packing versus self-manufacturing decision is not permanent. The best approach evolves as your volume grows, your team's capabilities expand, and your margin requirements change. Run the break-even analysis annually and adjust your production strategy accordingly.
Making the Decision
Calculate your true co-packing COGS (not the quoted price). Model your self-manufacturing fixed and variable costs honestly. Run the break-even analysis with conservative assumptions. Check whether your resulting retail price is competitive in your category.
If co-packing keeps you competitive and profitable at your current volume, stay with it. If the numbers show that self-manufacturing unlocks meaningfully better margins and you have the operational bandwidth to execute it, start planning the transition.
Either way, the production decision should serve your retail growth strategy, not the other way around.
