Amazon FBA Fees Explained: What Sellers Actually Pay
Break down referral, fulfilment, storage and closing fees so you know your true Amazon FBA margin before you list.
Selling on Amazon FBA looks simple until you stack every fee. Most sellers underestimate how referral, fulfilment, and storage eat into margin — especially on low-priced items.
The core FBA fee stack
Every FBA sale typically includes:
- Referral fee — usually 15% of the item price (category-dependent).
- FBA fulfilment fee — pick, pack, and ship based on size/weight tier.
- Monthly storage — charged per cubic foot; spikes in Q4.
- Optional closing fee — applies to media categories.
Add inbound shipping and PPC, and your break-even price climbs fast.
Why margin math matters
A £25 item with £8 product cost is not automatically profitable. If referral + FBA + storage totals £7, you may be left with under £2 before ads — and returns can wipe that out.

Three practical tips
- Price for fees first — set minimum viable price from total cost, not competitor price alone.
- Watch size tiers — a few millimetres can bump you into a higher FBA band.
- Automate repricing — Kepll applies the same cost model across your catalog so you never slip below break-even.
