Understanding Amazon FBA Profitability

Selling on Amazon Fulfillment by Amazon (FBA) can be highly lucrative, but many sellers fail because they don't accurately account for all expenses. Using a detailed Amazon FBA Profit Calculator is essential for determining if a product is worth sourcing.

Key Components of FBA Fees

  • Referral Fees: This is Amazon's "commission" for selling on their platform. It is typically 15% for most categories, though it varies from 8% to 45%.
  • Fulfillment Fees: This covers picking, packing, and shipping your product to the customer. This fee depends heavily on the weight and dimensions of your product.
  • Storage Fees: Amazon charges you to keep your inventory in their warehouses. These fees increase during the peak Q4 holiday season.
  • COGS (Cost of Goods Sold): The actual cost to manufacture or purchase the product from your supplier.

Calculating Your ROI and Margin

A "good" Amazon product typically targets at least a 30% profit margin and a 100% ROI. This gives you enough "buffer" to handle price wars, increased PPC costs, or returns without going into the red.

Calculation Example:

If you sell a product for $30.00:

  • Product Cost: $6.00
  • Shipping to Amazon: $1.00
  • Referral Fee (15%): $4.50
  • Fulfillment Fee: $5.00
  • PPC/Ads: $3.00
  • Total Cost: $19.50
  • Net Profit: $10.50
  • Profit Margin: 35%
  • ROI: 150%
