How to Use the Amazon FBA Profit Calculator
Succeeding on Amazon requires a deep understanding of your margins. This calculator is designed to help Private Label and Wholesale sellers determine if a product is viable after all Amazon-related expenses.
Understanding the Core Components
Referral Fee: This is Amazon's commission for selling on their platform. For most categories, this is 15% of the total selling price.
Fulfillment Fee: The cost Amazon charges to pick, pack, and ship your product. This varies based on the item's weight and dimensions.
COGS (Cost of Goods Sold): This includes your manufacturing costs and the cost to ship products from the supplier to Amazon's fulfillment centers.
PPC/Marketing: For new products, you will likely spend money on Amazon Advertising (Pay-Per-Click) to generate sales. Including this "per unit" cost gives a more realistic view of your actual take-home pay.
The "Rule of Three" for FBA Success
Experienced Amazon sellers often look for the "Rule of Three." This means your selling price is ideally split into three equal parts:
1/3 for Production and Shipping Costs.
1/3 for Amazon Fees and Marketing.
1/3 for Net Profit.
If your Profit Margin is over 25% and your ROI (Return on Investment) is over 100%, you generally have a healthy FBA business model that can withstand price fluctuations or increased competition.
