Understanding Your Amazon FBA Profit Margins
Calculating your potential profit on Amazon is critical before sourcing any product. This Amazon FBA Calculator accounts for the primary costs associated with the Fulfillment by Amazon program.
Key Components of FBA Profitability
Cost of Goods Sold (COGS): This is the manufacturing or purchasing cost of your product from the supplier.
Referral Fee: Amazon's "commission" for selling on their platform. For most categories, this is 15% of the total sale price.
Fulfillment Fee: The "Pick & Pack" fee Amazon charges to store, pack, and ship your product to the customer. This depends on weight and dimensions.
Storage Fees: Monthly costs for keeping your inventory in Amazon's warehouses. Note that these increase significantly during Q4 (October – December).

Example FBA Calculation
If you sell a product for $25.00, your costs might look like this:
Product Cost: $5.00
Shipping to Amazon: $0.50
Amazon Referral Fee (15%): $3.75
FBA Pick & Pack Fee: $4.50
Storage Fee: $0.10
Total Net Profit per unit: $11.15
Profit Margin: 44.6%
By using our calculator above, you can swap these numbers for your specific product dimensions and niche to ensure you stay in the green.
