Ultimate Guide to Amazon FBA Profit Calculation
Selling on Amazon through the Fulfillment by Amazon (FBA) program is a lucrative business model, but understanding your real numbers is the difference between a thriving brand and a failing one. This calculator helps you break down every cent to ensure your margins are healthy.
Key Factors in Your FBA Profitability
Cost of Goods Sold (COGS): This is the manufacturing or purchase price of your product from the supplier.
Referral Fees: Amazon charges a percentage of the total sales price for every item sold. For most categories, this is 15%.
FBA Fulfillment Fees: This covers picking, packing, shipping, and customer service. It depends heavily on the size and weight of your product.
Storage Fees: Amazon charges monthly fees to store your inventory in their warehouses. These increase during Q4 (October–December).
Example Calculation
Imagine you sell a Yoga Mat for $40.00. Your manufacturing cost is $10.00 and shipping to Amazon costs $2.00. Amazon takes a 15% referral fee ($6.00) and an FBA fulfillment fee of $7.50. With $0.50 in storage fees:
To maximize your FBA profits, consider optimizing your packaging to fit into smaller size tiers, reducing fulfillment fees. Negotiate with suppliers for bulk discounts to lower your COGS, and maintain a high inventory turnover rate to minimize monthly storage costs.
