How to Calculate Amazon FBA Profit
Selling on Amazon FBA (Fulfillment by Amazon) is a powerful way to scale an e-commerce business, but the fee structure can be complex. To understand your true profitability, you must look beyond just the product cost and selling price.
Understanding the Key Metrics
Referral Fee: This is Amazon's commission for selling on their platform. For most categories, this is 15% of the total sales price.
Fulfillment Fee: This covers picking, packing, and shipping your product to the customer. It is based on the weight and dimensions of your product.
Land Cost: This includes your manufacturing cost and the cost to ship the product from your supplier to an Amazon warehouse.
Storage Fees: Amazon charges monthly fees based on the volume (cubic feet) your inventory occupies in their fulfillment centers.
The Formula for FBA Profit
The core calculation used by our tool is:
Net Profit = Selling Price – (Product Cost + Shipping to Amazon + Referral Fee + Fulfillment Fee + Storage Fee + Marketing Spend)
Example Calculation
If 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
Ad Spend: $4.00
Total Expenses = $29.50. Your Net Profit would be $10.50 , resulting in a 26.25% profit margin.
