How to Use the Amazon FBA Profit Calculator
Understanding your bottom line is critical for success in the Amazon marketplace. This tool helps you break down the true cost of selling via Fulfillment by Amazon (FBA).
Key Metrics Explained:
Cost of Goods (COGS): The total cost to manufacture or purchase the product from your supplier.
Amazon Referral Fee: The commission Amazon takes for every sale (typically 15% for most categories).
FBA Fulfillment Fee: The flat fee covering picking, packing, and shipping to the customer.
PPC Spend: Your estimated marketing cost per unit sold (Total Ad Spend / Total Units Sold).
ROI: Return on Investment calculates how much profit you made relative to your initial product cost.
FBA Profit Calculation Example:
If you sell a "Yoga Mat" for $40.00:
Product Cost: $10.00
Referral Fee (15%): $6.00
FBA Fee: $7.50
Shipping to Amazon: $1.00
PPC per unit: $3.00
Total Profit: $12.50
Margin: 31.25%
ROI: 125%
Note: This calculator provides estimates based on your inputs. Always verify current Amazon fee structures in Seller Central as they are subject to seasonal changes.
