How to Calculate Amazon FBA Profits
Success on Amazon hinges on understanding your "true" net margin. Many sellers focus on gross revenue but overlook the intricate fee structure of Fulfillment by Amazon (FBA). To get an accurate profit calculation, you must account for several key variables:
Selling Price: The final price the customer pays for your product.
COGS (Cost of Goods Sold): The manufacturing or wholesale cost per unit.
Referral Fee: Amazon's commission for selling on their platform (typically 15% for most categories).
FBA Fulfillment Fee: The cost Amazon charges to pick, pack, and ship your product. This varies based on size and weight.
Storage Fees: Monthly costs for holding inventory in Amazon's warehouses. These increase during Q4 (October – December).
Realistic FBA Calculation Example
Imagine you are selling a yoga mat for $35.00 . Your manufacturing cost is $10.00 and it costs $1.50 to ship it to an Amazon fulfillment center. The FBA fee is $7.00 , and the referral fee (15%) is $5.25 . If you spend $4.00 per unit on PPC advertising:
Total Expenses: $10.00 + $1.50 + $7.00 + $5.25 + $4.00 = $27.75
Net Profit: $35.00 – $27.75 = $7.25
Profit Margin: 20.7%
ROI: 72.5%
Strategies to Improve FBA Margins
If your margins are below 15%, consider these optimizations:
Reduce Packaging Size: Moving from "Large Standard" to "Small Standard" size tiers can save dollars per unit in FBA fees.
Optimize PPC: Focus on high-converting keywords to lower your ACOS (Advertising Cost of Sale).
Bulk Shipping: Use sea freight instead of air freight to lower your inbound shipping costs per unit.
