How to Calculate Amazon FBA Profit

Understanding your true profit margins is critical for any Amazon seller. While your "Sales" dashboard might look impressive, the net profit is what actually goes into your bank account after Amazon takes their cut.

The Core Components of FBA Fees

  • Referral Fees: This is essentially Amazon's commission for selling on their platform. For most categories, this is 15% of the total sales price.
  • FBA Fulfillment Fees: This covers the cost of picking, packing, and shipping your product to the customer. This fee varies based on the size and weight of your item.
  • Storage Fees: Amazon charges you for every cubic foot of space your inventory occupies in their warehouses. Note that these fees increase significantly during the Q4 holiday season.

Example Calculation

Imagine you sell a Yoga Mat for $40.00.

  • Product Cost: $10.00
  • Shipping to Amazon: $2.00
  • Referral Fee (15%): $6.00
  • Fulfillment Fee: $7.50
  • Monthly Storage: $0.50

Total Costs: $10 + $2 + $6 + $7.50 + $0.50 = $26.00

Net Profit: $40.00 – $26.00 = $14.00

Profit Margin: 35%

Strategies for Better Margins

To improve your Amazon FBA profitability, focus on "Small and Light" programs if your items are low-cost. Additionally, optimizing your packaging to reduce the product's dimensional weight can significantly lower your fulfillment fees.
