Amazon FBM vs FBA Fees UK
FBA is a fulfilment product, not a personality trait. Same SKU, two cost stacks — then decide.
Updated August 2026 · Fee assumptions
Open both Amazon FBM and Amazon FBA in the calculator ranking. Keep price and cost identical. Change only fulfilment and return assumptions.
Worked example
If FBA only wins with 0% returns and a fantasy fulfilment quote, do not send a pallet yet.
Frequently asked questions
Is FBA cheaper than FBM in the UK?
Rarely on fees alone. FBA can win on conversion and time — only if contribution still clears after fulfilment and returns.
What should I compare first?
Referral + your FBA quote vs referral + your outbound postage, with the same return rate.
