Amazon FBA vs FBM: Which Fulfillment Method Earns More Profit?

One of the most common questions new Amazon sellers face is whether to use FBA (Fulfillment by Amazon) or FBM (Fulfillment by Merchant). The answer depends heavily on your product category, price point, and sales volume.

FBA handles storage, picking, packing, shipping, and customer service for you. In return, Amazon charges fulfillment fees based on your product's size and weight tier, plus storage fees that vary by season. For a standard 1-pound product in the Large Standard size tier, FBA fees typically range from $4.50 to $8.00 per unit.

FBM gives you control over fulfillment. You store inventory, pack orders, and ship directly to customers. This avoids FBA storage and fulfillment fees but requires you to manage outbound shipping costs ($3-6 per unit for standard packages) and maintain your own fulfillment infrastructure.

Our profit comparison tool shows a clear pattern: low-priced items under $20 often perform better with FBM because FBA fees consume too much of the margin. Higher-priced items above $30 can absorb FBA fees and benefit from Prime visibility. Bulky or heavy items almost always favor FBM due to dimensional weight pricing on FBA.

For TikTok Shop sellers, the same logic applies — FBT (Fulfillment by TikTok) is convenient but comes with fees similar to FBA. Self-fulfilled TikTok Shop orders can save 8-15% on fulfillment costs, making it the better choice for price-sensitive products.
