—
FBM has no FBA fulfilment fee, but you cover shipping and packaging and still pay the category referral fee. Referral rates vary by category and change — treat this as an estimate.
FBM vs. FBA
With FBM you hold and ship stock yourself, so no fulfilment fee but you absorb postage, packaging and handling time. Amazon still takes a referral fee on the sale. Many sellers compare FBM vs FBA per unit — use this alongside the FBA calculator to see which nets more.
How Amazon FBM works
Fulfilled by Merchant: you handle packing, shipping, and returns. Fees are simpler — only the Amazon Referral fee (typically 15%) plus your actual shipping costs. No Prime badge, but full control over fulfillment.
Frequently asked questions
What does Amazon charge on an FBM sale?
The category referral fee (usually ~15%) plus any per-item or closing fees. You pay your own shipping and packaging rather than an FBA fulfilment fee.
Is FBM cheaper than FBA?
It depends on unit size and weight. FBM can beat FBA for small, light items; FBA's faster logistics can lift sales. Compare per-unit profit for your specific product.
