How to Use the Amazon FBA Profit Calculator
Success on Amazon hinges on understanding your numbers. Many sellers fail because they overlook "hidden fees" like referral percentages, storage costs, and PPC overhead. This tool is designed to provide a comprehensive breakdown of your unit economics.
Key Metrics Explained
- 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 "Pick & Pack" fee. This covers the labor and materials Amazon uses to ship your product to the customer. It varies based on product weight and dimensions.
- Storage Fee: The cost to keep your inventory in Amazon's warehouses. This typically increases during the Q4 holiday season.
- ROI (Return on Investment): Tells you how much money you made relative to the cost of purchasing and shipping the inventory. A 100% ROI means you doubled your investment.
- Net Margin: The percentage of the selling price that is pure profit after all expenses.
Realistic Example: Private Label Product
Imagine you are selling a "Silicone Spatula Set":
- Selling Price: $24.99
- Unit Cost (Landings): $4.50
- Shipping to FBA: $0.80
- Referral Fee (15%): $3.75
- FBA Fee: $5.40
- PPC Spend: $3.00
In this scenario, your Total Cost per unit is $17.45, leaving you with a Net Profit of $7.54. This results in a 30.2% Profit Margin and a healthy 142.2% ROI.
Strategies to Increase Your Profit
- Optimize Packaging: Reducing the size of your product box by just half an inch can often move your product into a lower FBA fulfillment tier, saving you dollars per unit.
- Negotiate with Suppliers: Once you have sales volume, request "MOQ" (Minimum Order Quantity) discounts to lower your unit cost.
- Manage ACoS: Keep a close eye on your Advertising Cost of Sales. If your PPC spend per unit is too high, it will eat your entire margin.
