How to Calculate Amazon FBA Profitability
Selling on Amazon through the Fulfillment by Amazon (FBA) program involves several layers of costs that can significantly impact your bottom line. To find your true profit, you must subtract all operational and platform-specific costs from your total sales price.
Understanding the Key Metrics
Selling Price: The final amount the customer pays for your product on Amazon.
Referral Fee: This is Amazon's commission for using their marketplace. For most categories, this is 15% of the total selling price.
Fulfillment Fee: This covers picking, packing, and shipping your product to the customer. It varies based on the size and weight of the item.
Landed Cost: This includes the product manufacturing cost plus the cost of shipping the inventory to Amazon's fulfillment centers.
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
FBA Fulfillment Fee: $7.50
PPC Marketing: $4.50
Total Expenses: $30.00 | Net Profit: $10.00 | Profit Margin: 25% | ROI: 100% (Profit / Cost of Product + Shipping).
Tips to Improve FBA Margins
To increase your profitability, consider optimizing your packaging to reduce the FBA size tier, negotiating lower manufacturing costs, or improving your PPC conversion rate to lower marketing spend per unit.
