What is Break-Even ACoS?

Break-Even ACoS (Advertising Cost of Sales) equals your profit margin before advertising. If your product sells for $100 and your landed cost plus Amazon fees equals $70, your pre-ad profit is $30, or 30%. Therefore, your Break-Even ACoS is 30%. If your ACoS goes above 30%, you are losing money on every ad-driven sale.

Sourcing to Support Ad Spend

If your imported product does not have a large enough gross margin multiplier, you will not be able to afford Amazon PPC. In highly competitive niches (like supplements or gym accessories), Cost Per Click (CPC) rates are astronomical. You must engineer your China sourcing strategy to achieve a landed cost low enough to support a 30% to 40% Break-Even ACoS.

Tips for China Importers

Calculate your total Amazon cost before importing. FBA referral fee + fulfillment fee + storage + PPC + returns typically absorbs 45–55% of your selling price. Build this into your landed cost model before placing an order.
Start with 300–500 units for launch. Launching with 2,000+ units before validating demand is one of the most common (and expensive) mistakes. Test velocity with a smaller shipment first.
Send FBA-ready cartons from China. Prep work (poly-bagging, labeling, bundling) done in China costs $0.05–0.20/unit. Done at an Amazon prep center in the US: $0.50–1.50/unit. Same work, 5–10× the cost.
Account for returns in your margin model. Amazon electronics return rates: 10–20%. Apparel: 20–30%. Toys/general: 5–10%. Factor your category's return rate into your per-unit profit calculation.
Track your IPI score to avoid storage surcharges. Amazon charges long-term storage fees on inventory over 365 days. Keep your Inventory Performance Index (IPI) above 400 to avoid storage limits and surcharges.
