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 is sustainable, you must look beyond top-line revenue and focus on your Net Profit.

Key Metrics Explained

  • Referral Fee: This is essentially Amazon's commission for selling on their platform. For most categories, this is 15% of the total selling price.
  • FBA Fulfillment Fee: This covers the cost of picking, packing, and shipping your product to the customer. This varies based on the size and weight of the item.
  • Storage Fees: Amazon charges you for the space your inventory occupies in their fulfillment centers. These fees typically increase during the Q4 holiday season.
  • ROI (Return on Investment): This shows how much profit you make relative to the cost of your inventory. An ROI of 100% means you doubled your money.

FBA Profit Example

Imagine you source a product for $10.00 and sell it for $35.00. Your costs might look like this:

Expense Item Amount
Referral Fee (15%) $5.25
Fulfillment Fee $6.50
Shipping to Amazon $1.00
Total Expenses $22.75
Net Profit $12.25

In this scenario, your Profit Margin is 35% and your ROI is 122.5%. This indicates a very healthy product choice.

How to Improve Your FBA Margins

If your results are lower than expected, consider these three strategies:

  1. Optimize Packaging: Dropping just an inch or a few ounces can move your product into a lower FBA tier, saving you dollars per unit.
  2. Bulk Shipping: Reduce your "Shipping to Amazon" costs by sending larger shipments via LTL (Less Than Truckload) rather than small parcel.
  3. Negotiate COGS: As your volume increases, work with your manufacturer to lower the product cost, which has the biggest impact on your ROI.
