How to Calculate Landed Cost (COGS)

How to Calculate Landed Cost (COGS)

You find a brilliant product at the Canton Fair. The factory boss quotes you $5.00 per unit. You check Amazon, and the product sells for $25.00. You calculate a massive $20 profit margin and immediately order 2,000 units.

Six months later, your accountant hands you your P&L statement. You didn't make a $40,000 profit; you actually lost $2,000. You forgot the invisible taxes of international trade.

💡 Withyou Trip Expert Verdict: "The absolute deadliest financial illusion is Confusing 'Ex-Works Price' with 'Landed Cost'. The $5.00 the factory charges is just the raw plastic and labor. To get that plastic to an American consumer, it must run a gauntlet of freight, tariffs, broker fees, Amazon pick-and-pack fees, and PPC advertising. A standard rule of thumb: Your true Landed Cost to the FBA warehouse is almost always 30% to 50% higher than the raw factory unit price. You MUST build a rigorous COGS (Cost of Goods Sold) spreadsheet."

1. The Landed Cost Calculation Matrix

Expense Category The Hidden Cost Example (On a $5.00 Item)
Factory Unit Cost The raw EXW/FOB price. $5.00
Ocean/Air Freight The cost to cross the ocean (per unit). $1.20
US Customs Tariffs e.g., 25% Section 301 Duty. $1.25
Broker/Port Fees HMF, MPF, ISF filing, Trucking to warehouse. $0.40
True Landed Cost What it costs to sit in your warehouse. $7.85

2. The Dimensional Weight (DIM) Destroyer

Freight costs are not based on what the product weighs; they are based on how much space it steals on the ship.

3. The 3x Retail Rule

If your True Landed Cost is $7.85, what should your retail price on Amazon or Shopify be?

❓ Frequently Asked Questions (FAQ)

Q: Do I include the cost of the Third-Party QC Inspection in my Landed Cost? A: Yes, absolutely. Every single dollar spent to get the product from the factory floor to the final fulfillment warehouse must be capitalized into the inventory asset value. If you pay $300 for an SGS inspection, $50 for a Telex Release fee, and $200 for a Customs Bond, you divide that $550 by your total units and add it to the unit cost. This is the only way to calculate true Gross Margin.
