Understanding Amazon FBA Profitability
Selling on Amazon via Fulfillment by Amazon (FBA) is a powerful way to scale an e-commerce business, but the fee structure can be complex. To ensure your business remains sustainable, you must calculate your "Net Profit" after all Amazon-specific deductions.
Key Components of the FBA Calculation
- Selling Price: The list price customers pay on Amazon.com.
- COGS (Cost of Goods Sold): What you paid the manufacturer for the product, including packaging.
- Referral Fee: Amazon's "commission" for selling on their platform. Most categories are 15%, but some vary from 8% to 45%.
- FBA Fulfillment Fee: A flat fee per unit that covers picking, packing, shipping, and customer service. 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 during the Q4 holiday season.
FBA Profit Calculation Example
Imagine you are selling a yoga mat:
| Selling Price | $35.00 |
| Product Cost + Shipping | -$10.00 |
| Amazon Referral Fee (15%) | -$5.25 |
| FBA Fulfillment Fee | -$6.50 |
| Net Profit | $13.25 |
In this scenario, your Profit Margin is 37.8% and your ROI is 132.5%. Generally, Amazon sellers aim for a "Rule of Three": 1/3 for product costs, 1/3 for Amazon fees, and 1/3 for profit.
Top Tips for Increasing FBA Margins
- Optimize Packaging: Lowering your product's dimensions or weight by even an inch or an ounce can move you into a lower FBA fee tier.
- Negotiate with Suppliers: As your volume grows, work with manufacturers to lower the unit cost.
- Monitor Storage: Use "Sell-through" reports to avoid Aged Inventory Surcharges for products sitting in warehouses for over 180 days.
