Understanding Amazon FBA Fees in the UK
Selling on Amazon via FBA (Fulfilment by Amazon) involves two main fees: the Referral Fee and the Fulfilment Fee. The Referral Fee is Amazon's commission for selling on their marketplace, usually ranging from 8% to 15% depending on the exact product category.
The Fulfilment Fee covers the cost of Amazon picking, packing, and shipping your product to the customer. This fee is strictly determined by the dimensions and weight of your item. Larger, heavier items incur significantly higher fulfilment costs.
Hidden FBA Costs to Watch Out For
Beyond the standard referral and fulfilment fees, sellers must also account for Monthly Storage Fees, which are charged per cubic foot of space your inventory occupies in Amazon's warehouses. These storage fees triple during the Q4 peak season (October to December).
If your inventory sits unsold for over 331 days, you will also be hit with Long-Term Storage Fees. Using an accurate Amazon FBA Calculator is essential for pricing your products correctly and protecting your profit margins.
Frequently Asked Questions
What are the Amazon seller fees in the UK for 2026?
Amazon frequently updates their fee structures. In the UK, standard referral fees hover around 15.3% for most categories (including the 2% Digital Services Tax). Fulfilment fees have shifted towards more granular weight and dimension tiers. Use this calculator to get exact, up-to-date fee estimates based on your product's size.
Is Amazon FBA still profitable in the UK?
Yes, Amazon FBA can still be highly profitable, but strict margin control is required. You must accurately factor in manufacturing costs, shipping to the fulfilment centre, VAT, Amazon referral fees, and FBA fulfilment fees to ensure a healthy net profit margin.
How do eBay selling fees compare to Amazon FBA?
eBay generally charges a single final value fee (around 10-12% plus a fixed 30p charge) and does not handle fulfilment. Amazon FBA charges higher total fees but handles the entire logistics and customer service process, typically resulting in much higher sales volume due to Prime eligibility.
