How to Calculate Amazon Seller Profitability

Selling on Amazon can be highly lucrative, but understanding your true net profit is essential for long-term success. Many new sellers focus solely on the sale price, forgetting that Amazon takes a significant cut through various fees. Our Amazon FBA Profit Calculator helps you visualize the “take-home” pay after all expenses are accounted for.

Understanding the Key Metrics

Cost of Goods (COGS): This is the total cost to manufacture or purchase your product. It should include factory costs, packaging, and any quality inspection fees.

Referral Fees: Amazon typically charges a percentage of the total sale price (usually 8% to 15% depending on the category). This is essentially their “commission” for providing the marketplace.

FBA Fees: If you use “Fulfillment by Amazon,” these fees cover storage, picking, packing, and shipping to the customer. These are determined by the weight and dimensions of your product.

Example Calculation: Private Label Product

  • Sale Price: $40.00
  • Product Cost: $10.00
  • FBA Fees: $6.50
  • Referral Fee (15%): $6.00
  • Marketing (PPC): $4.00
  • Total Expenses: $26.50
  • Net Profit: $13.50
  • Profit Margin: 33.75%

3 Tips to Increase Your Amazon Profit Margins

  1. Optimize Packaging: Reducing the size or weight of your product by even an inch or an ounce can move you into a lower FBA fee tier, saving you dollars on every single sale.
  2. Bundle Products: By bundling two items together, you pay the FBA shipping fee once instead of twice, significantly increasing the margin per order.
  3. Negotiate with Suppliers: Once you have a steady sales volume, renegotiate your unit cost. A $0.50 reduction in COGS goes directly to your bottom line.
