How to Use the Amazon FBA Profit Calculator

Success on Amazon depends on understanding your "true" numbers. Many sellers focus on revenue, but it is the net profit that determines if your business is sustainable. This calculator helps you break down every expense involved in the Fulfillment by Amazon (FBA) process.

Key Metrics Explained

  • Product Selling Price: The final price the customer pays for your item on Amazon.
  • Cost of Goods Sold (COGS): The total cost to manufacture or purchase one unit of your product.
  • Amazon Referral Fee: This is Amazon's "commission" for selling on their platform. For most categories, this is 15% of the selling price.
  • FBA Fulfillment Fee: This covers picking, packing, and shipping your product to the customer. This depends on the size and weight of your product.
  • Ship to Amazon: The cost to transport your inventory from your supplier or warehouse to an Amazon Fulfillment Center.

Example Calculation

Imagine you are selling a kitchen gadget for $25.00. Your manufacturing cost is $5.00, and it costs $1.00 to ship it to Amazon. If the referral fee is 15% ($3.75) and the FBA fulfillment fee is $5.50, and you spend $0.25 on monthly storage:

  • Total Revenue: $25.00
  • Total Expenses: $5.00 + $1.00 + $3.75 + $5.50 + $0.25 = $15.50
  • Net Profit: $9.50
  • Profit Margin: 38%
  • ROI: 190% (Profit divided by Cost of Goods)

Strategies to Improve Your FBA Margins

If your margins are slim (below 20%), consider optimizing your sourcing costs by negotiating with suppliers or reducing product packaging size to lower FBA fulfillment fees. Always account for PPC (Pay-Per-Click) advertising costs when planning your long-term business strategy, as these costs can eat into your net profit significantly during the launch phase.
