How to Use the Amazon FBA Profit Calculator
Selling on Amazon via Fulfillment by Amazon (FBA) is a lucrative business model, but hidden fees can quickly erode your margins. This calculator helps you determine exactly how much you take home after Amazon takes their cut.
Understanding FBA Fee Components
- Referral Fee: Amazon's commission for selling on their platform. This is usually 15% for most categories.
- Fulfillment Fee: The cost for Amazon to pick, pack, and ship your item to the customer. This depends on the size and weight of your product.
- Storage Fees: Monthly costs for keeping your inventory in Amazon's fulfillment centers. These fees increase significantly during Q4 (October–December).
- Cost of Goods (COG): The manufacturing and shipping cost to get your product from the supplier to your door or prep center.
Example Calculation
Suppose you are selling a yoga mat for $40.00:
- Cost of Product: $10.00
- Shipping to Amazon: $2.00
- Amazon Referral Fee (15%): $6.00
- FBA Pick & Pack Fee: $7.50
- Storage: $0.50
- Total Expenses: $26.00
- Net Profit: $14.00
- Profit Margin: 35%
Why ROI and Margin Matter
While profit tells you the dollar amount, ROI (Return on Investment) tells you how hard your money is working. A 100% ROI means you doubled your money. Profit Margin tells you how much of your total revenue is pure profit. Most successful FBA sellers aim for a margin of at least 25% to account for unexpected costs like PPC advertising and returns.
