COGS (Cost of Goods Sold)

COGS (Cost of Goods Sold) is the per-unit production and acquisition cost of inventory. Manufacturing + packaging + inbound freight + duties. Nothing else.

[01] // How it actually works

In practice.

COGS is where margin lives or dies. A clean COGS number includes every direct cost between the raw material and the warehouse door — and excludes every indirect cost beyond it. The mistake most founders make is conflating COGS with landed cost or with operating expenses, which produces unit economics that don't survive an audit.

What's in COGS for a private-label CPG product:

  • Raw material cost (the bulk product, ingredients)
  • Manufacturing labor allocated to the run
  • Primary packaging (bottle, jar, pouch)
  • Secondary packaging (carton, label, induction seal)
  • Tertiary packaging (case packs, master cartons)
  • Inbound freight (factory to your 3PL)
  • Duties and customs if imported
  • Direct QC and stability testing allocated to the lot

What's not in COGS: rent on your office, your salary, marketing spend, shipping to the customer, Amazon FBA fees, payment processing, return handling, customer service. Those are SG&A.

For a typical private-label supplement at 5,000-bottle MOQ, COGS lands $2.50-6.00 per unit. The active ingredient is usually 30-50% of COGS; packaging is 20-35%; everything else fills out the rest. Cosmetics serums have similar splits with packaging often higher (premium glass costs more than HDPE bottles).

[02] // Founders' trap

What founders get wrong about COGS (Cost of Goods Sold).

// Real-talk

The most common COGS error: forgetting to allocate inbound freight, duties, and case-pack costs. A factory quotes you $3.20 per bottle EXW (ex-works). You assume that's your COGS. It's not — by the time the goods land at your 3PL with $0.40 of freight and $0.20 of duties and a $0.15 case-pack allocation, your real COGS is $3.95. Run unit economics against that number, not against the factory quote.

The second error: under-counting labels and inserts. A four-color shrink-wrap label can cost more per unit than the bottle. Get itemized packaging quotes, not bundled ones.
