How to Calculate Amazon FBA Profitability
Selling on Amazon through the Fulfillment by Amazon (FBA) program is a lucrative opportunity, but the fee structure can be complex. To ensure your business is sustainable, you must account for every cent spent from manufacturing to the customer's doorstep.
Key Fees to Consider
Referral Fees: This is Amazon's commission for selling on their platform. For most categories, this is 15% of the total selling price.
FBA Fulfillment Fees: This covers picking, packing, and shipping your product. It is determined by the size and weight of your item.
Cost of Goods Sold (COGS): The total cost to manufacture or purchase one unit of your product.
Inbound Shipping: The cost to send your inventory from your supplier or warehouse to an Amazon Fulfillment Center.
Storage Fees: Amazon charges monthly fees based on the volume (cubic feet) your inventory occupies in their warehouse.
Example Calculation
If you sell a yoga mat for $40.00:
Cost of Mat: $10.00
Amazon Referral Fee (15%): $6.00
FBA Fulfillment Fee: $7.50
Shipping to Amazon: $1.50
PPC Advertising: $3.00
Total Expenses: $28.00
Net Profit: $12.00
Profit Margin: 30%
Strategies to Improve Your FBA Margins
To increase your bottom line, consider optimizing your packaging to fit into smaller size tiers, reducing FBA fulfillment fees. Additionally, sourcing in higher volumes can lower your COGS, and improving your "ACOS" (Advertising Cost of Sales) ensures your marketing budget isn't eating all your profits.
