Understanding Amazon FBA Profitability
Selling on Amazon through Fulfillment by Amazon (FBA) is an excellent way to scale an e-commerce business, but understanding your numbers is critical to success. This Amazon FBA Profit Calculator helps you peel back the layers of fees to see what you actually take home.
How to Use the Calculator
To get an accurate result, you need to account for every stage of the product lifecycle:
Selling Price: The final price customers pay on Amazon.
Cost of Goods (COGS): The manufacturing cost per unit.
Shipping to Amazon: The cost to transport your inventory from your supplier or warehouse to Amazon's fulfillment centers.
FBA Fee: The flat fee Amazon charges to pick, pack, and ship your item. This is based on weight and dimensions.
Referral Fee: Amazon's "commission" for selling on their platform, typically 15% for most categories.
The Formulas Used
Our calculator utilizes the following industry-standard formulas:
Total Fees = (Selling Price * Referral %) + FBA Fee
Net Profit = Selling Price – COGS – Shipping – Total Fees – Misc
ROI = (Net Profit / (COGS + Shipping + Misc)) * 100
Example Calculation
Imagine you sell a yoga mat for $40.00. Your manufacturing cost is $10.00, and shipping it to Amazon costs $2.00. Amazon's FBA fee is $7.50, and the referral fee is 15% ($6.00). After miscellaneous costs of $0.50, your net profit would be $14.00. This results in a 35% profit margin and a 112% ROI.
