Understanding Your Amazon FBA Profit Margins

Selling on Amazon through the Fulfillment by Amazon (FBA) program offers massive scale, but the fee structure can be complex. To succeed as a private label seller or reseller, you must accurately account for every cent that leaves your pocket.

Key Fees Explained

Referral Fees: This is Amazon's commission for selling on their platform. For most categories, this is 15% of the total selling price.

Fulfillment Fees: This covers the picking, packing, and shipping of your orders to the customer. This varies based on the weight and dimensions of your product.

Monthly Storage Fees: Amazon charges you for the space your inventory occupies in their fulfillment centers. These fees typically increase during the Q4 holiday season.

Example Calculation

If you sell a yoga mat for $40.00:

  • Product Cost: $10.00
  • Shipping to Amazon: $1.00
  • Referral Fee (15%): $6.00
  • FBA Fulfillment Fee: $7.50
  • Storage Fee: $0.30

Your total costs would be $24.80, leaving you with a Net Profit of $15.20, a 38% Profit Margin, and a 138% ROI.

How to Improve Your Margins

To increase your profitability, focus on optimizing your packaging to reduce the FBA Fulfillment tier (size/weight) and negotiate better rates with your manufacturers to lower your Cost of Goods Sold (COGS).
