Amazon FBA Fees UK Calculator
Referral fee + fulfilment is the real stack. Guessing FBA costs is how inventory gets stuck.
Updated August 2026 · Fee assumptions
Amazon fees are not one number. Paste your fulfilment quote into the calculator, keep referral as an estimate, and compare FBM vs FBA with returns on.
Worked example
£45 sale with £4.50 FBA fulfilment and ~15% referral often lands well below private eBay — only worth it if sell-through pays for the cut.
