Understanding Amazon FBA Costs

To succeed as an Amazon seller, you must look beyond the selling price. This calculator accounts for the four primary pillars of FBA expenses:

  • Cost of Goods (COGS): The total cost to manufacture or purchase one unit.
  • Amazon Referral Fee: The commission Amazon takes (usually 15% for most categories).
  • Fulfillment Fee: The cost for Amazon to pick, pack, and ship your product to the customer.
  • Landed Costs: The shipping costs involved in getting your product from the factory to Amazon's warehouses.

Example Calculation

If you sell a yoga mat for $40.00:

  • Product Cost: $10.00
  • Referral Fee (15%): $6.00
  • FBA Fee: $7.50
  • Shipping to Amazon: $1.50
  • Total Profit: $15.00
  • Margin: 37.5%
