How to Use the Amazon FBA Profit Calculator

Calculating your potential margins before sourcing a product is the difference between a successful Amazon business and a costly mistake. Our Amazon FBA Profit Calculator helps you visualize your bottom line by factoring in all common fees associated with the Fulfillment by Amazon program.

Understanding the Core Metrics

  • Selling Price: The list price of your product on the Amazon marketplace.
  • COGS (Cost of Goods Sold): The total cost to manufacture or purchase one unit from your supplier.
  • Amazon Referral Fee: Typically 15% for most categories, this is the "commission" Amazon takes for providing the customer.
  • FBA Fulfillment Fee: The flat fee covering picking, packing, and shipping to the customer. This depends on product size and weight.
  • Marketing/PPC: Don't forget your advertising spend. Most successful sellers allocate $1-$3 per unit for Pay-Per-Click ads.

Realistic Example: Kitchen Gadget

Imagine you are selling a premium silicone spatula for $24.99. Your manufacturing cost is $5.00 per unit. Shipping it to an Amazon warehouse costs $0.50 per unit. If the FBA fulfillment fee is $5.40 and you spend $2.50 on ads per sale:

  • Revenue: $24.99
  • Amazon Referral Fee (15%): $3.75
  • FBA Fee: $5.40
  • Total Expenses: $17.15 (including COGS and PPC)
  • Net Profit: $7.84
  • Margin: 31.3%

Why ROI and Margin Matter

While Net Profit tells you how much cash you keep per sale, ROI (Return on Investment) tells you how hard your money is working. A 100% ROI means for every $1 spent on stock, you get $1 back in profit. Professional Amazon sellers usually aim for a Net Margin of at least 20% to account for returns and price fluctuations.
