A complete breakdown of Amazon seller fees UK brands pay in 2026, from referral and FBA fees to storage and hidden charges. Protect your margins.
If you sell on Amazon UK, the platform is likely taking between 25% and 45% of your retail price before you see a penny of profit. That range is wide because Amazon seller fees UK brands face are not one flat commission. They are a stack of individual charges, each calculated differently, and several of them changed at the start of 2026.
We work with brands across dozens of categories, and one pattern repeats itself: most sellers can name the referral fee percentage for their products, but very few can accurately state their true all-in cost per unit. That gap is where margin leaks live.
This post breaks down every fee Amazon charges UK sellers in 2026, explains what changed this year, and gives you a framework for calculating your actual cost per sale.
Why Understanding Amazon Seller Fees Matters More in 2026
Amazon updated its European fee structure in January 2026, delivering what it described as one of its largest-ever fee reductions across the continent. FBA fulfilment fees for parcels dropped by an average of £0.26 per unit in the UK, and referral fees were cut in several high-volume categories including clothing, home products, and grocery.
That sounds like good news, and for many sellers it is. The catch is that other fees moved in the opposite direction. Monthly storage rates increased, the aged inventory surcharge still applies from day 241 onwards, and a 1.5% fuel and logistics surcharge landed on all FBA fulfilment fees from April 2026. A new digital services fee adds a further 2% on top of selling and FBA fees for UK-established sellers.
The net result? If you only look at the headline reductions, you might assume your costs went down. In practice, the picture is more nuanced, and the brands that come out ahead are the ones modelling every fee line against their specific product mix.
Your Selling Plan Fee: The Starting Point
Every Amazon UK seller pays a subscription-level fee for access to the platform. The Individual plan costs £0.75 per unit sold, with no monthly commitment. The Professional plan costs £25 per month (excluding VAT) regardless of how many units you shift.
For any brand selling more than 34 units a month, the Professional plan pays for itself. If you are reading this as a representative of an established consumer goods brand, you should be on the Professional plan. It is a prerequisite for access to advertising, bulk listing tools, a Brand Store, and IP Protection.
This fee is straightforward and rarely surprises anyone. The layers that follow are where the complexity builds.
Amazon Referral Fees: The Category-Based Commission
The referral fee is the percentage Amazon takes on every sale, calculated on the total price the customer pays (including delivery charges but excluding VAT). Think of it as Amazon’s commission for putting your product in front of its customers.
Most categories sit between 8% and 15%. A minimum referral fee of £0.25 normally applies per item, which matters if you sell low-priced goods where a percentage-based fee would otherwise be smaller.
Referral fees vary significantly by product type. Consumer electronics attract 7-8%, health and personal care sits at 8-14%, home and garden ranges from 10-13%, sporting goods come in at 12-13%, books and media at 15%, and furniture at around 12%.
Clothing and accessories saw meaningful reductions this year. Items priced at or below £15 now attract a 5% referral fee (down from 8%), and items between £15 and £20 dropped from 15% to 10%. Home products priced under £20 fell from 15% to 8%. Grocery, vitamins, and pet food categories received targeted cuts for lower-priced items too.
The key takeaway for brand owners: your referral fee is not static. It shifts with your product’s sale price, and Amazon periodically adjusts rates by category. If you have not reviewed your category assignments recently, check that every ASIN sits in the correct category. Misclassification can mean you are overpaying.
Amazon FBA Fees UK: What Fulfilment Actually Costs
If you use Fulfilment by Amazon (and most established brands do), you pay a per-unit fee every time Amazon picks, packs, and ships one of your products. This fee varies by size tier and weight.
A small, light item (a skincare tube, for example) might cost around £1.83 to fulfil. A heavier parcel or an oversized product will cost significantly more. The exact rate depends on which of Amazon’s size tiers your product falls into: envelope, small parcel, standard parcel, small oversize, standard oversize, or large oversize.
Two changes matter in 2026. First, Amazon reduced FBA fulfilment fees for standard parcels by an average of £0.26 per unit in the UK. Second, the Low-Price FBA programme (which offers discounted fulfilment rates for cheaper products) expanded its eligibility threshold from £10 to £20. Products newly qualifying for this programme save an average of £0.40 per unit.
Set against those reductions, Amazon introduced a 1.5% fuel and logistics surcharge on all FBA fulfilment fees from 17 April 2026. On a £2.50 fulfilment fee, that adds roughly £0.04. On higher-cost oversized items, the surcharge becomes more noticeable.
If you sell across multiple European marketplaces, note that FBA fees differ by country. The UK, Germany, France, Italy, and Spain each have their own rate cards, and a product that is cost-effective to fulfil through Amazon in one market may carry higher fees in another.
Storage Fees and the Aged Inventory Trap
Amazon charges monthly storage fees based on the cubic footage your inventory occupies in its fulfilment centres. From January to September, the rate is approximately £0.75 per cubic foot per month. During the peak Q4 period (October to December), that rate jumps to between £2.00 and £2.40 per cubic foot.
The real cost that catches sellers off guard is the aged inventory surcharge. Any stock sitting in Amazon’s warehouses for more than 241 days attracts an additional charge on top of the standard monthly storage fee. This surcharge increases the longer inventory remains unsold, and it can erode margins on slow-moving lines quickly.
We see this pattern regularly with brands that over-order ahead of peak season, then carry surplus stock into the new year. A product that was profitable at full price in November can become a net loss by the following June if it is still sitting in FBA storage, accumulating surcharges week after week.
The practical lesson: match your inbound shipment quantities to realistic sell-through rates. Use Amazon’s Inventory Performance Index and restock recommendations as starting points, but cross-reference them with your own sales data and promotional calendar.
The Fees Most Sellers Overlook
Beyond the headline charges, several smaller fees add up. These rarely appear in the mental maths brands do when pricing products, which makes them a common source of margin erosion.
The digital services fee is relatively new and applies to UK-established sellers. It adds 2% on top of your selling and FBA fees for sales through Amazon.co.uk, and 3% for sales through Amazon’s French, Italian, and Spanish stores. On a product where your combined selling and FBA fees total £5, that is an extra £0.10 per unit for UK sales.
Closing fees apply to media products (books, DVDs, music, video games) and are charged on top of the referral fee. If your brand sells in these categories, factor them in.
The high-volume listing fee targets sellers with more than two million active non-media ASINs that have not sold in the past 12 months. At £0.0003 per ASIN above the threshold, it is designed to discourage catalogue bloat. Most consumer goods brands will not hit this limit, but if you manage a very large catalogue with legacy SKUs, an audit is worthwhile.
Returns processing fees deserve attention too. When a customer returns an FBA item, Amazon charges a return processing fee in certain categories. This cost is easy to miss during initial profitability modelling, and in categories with above-average return rates (clothing is the classic example), it can meaningfully affect your per-unit economics.
How to Calculate Your True Cost Per Unit on Amazon
Knowing each fee exists is one thing. Turning that knowledge into a usable number is where the value lies. Here is a straightforward framework we use with our managed service clients to calculate the real cost of selling a product through FBA on Amazon UK.
Start with the customer’s purchase price (inclusive of any delivery charge, exclusive of VAT). From that, subtract the referral fee for your category, the FBA fulfilment fee for your product’s size and weight tier, an estimated monthly storage cost per unit (divide your monthly storage bill by units in stock), and the digital services fee (2% of your combined selling and FBA fees). Then subtract your landed product cost (manufacturing, shipping to Amazon, labelling, and any prep fees).
What remains is your gross profit per unit before advertising spend.
Most brands we work with find that Amazon fees alone consume between 30% and 40% of their selling price, with the referral fee and FBA fulfilment fee making up the bulk. Layer on advertising costs (which for many categories run between 10% and 20% of revenue), and you can see why pricing strategy and fee awareness are so tightly linked to profitability.
Amazon provides a Revenue Calculator that gives fee estimates for any ASIN. It is a useful starting point, but we recommend building your own spreadsheet that incorporates your actual landed costs, realistic return rates, and advertising spend. The Revenue Calculator does not account for all the fees outlined above, and it cannot model your specific margin targets.
What to Do Next
Run a fee audit on your top 10 ASINs by revenue. For each one, calculate the total fees Amazon charges per unit sold (referral fee, FBA fee, storage allocation, digital services fee, and estimated return cost). Compare that total to the figure you have been using in your margin calculations. If there is a gap, you have found where profit is leaking.
Check your category assignments in Seller Central. Misclassified products may be attracting higher referral fees than necessary. Check your inventory age report and act on any stock approaching the 241-day surcharge threshold, whether that means running a promotion, adjusting pricing, or creating a removal order.
If you sell across multiple EU marketplaces from the UK, pay particular attention to the digital services fee. The 3% rate on French, Italian, and Spanish store sales is meaningful enough to affect your cross-border pricing strategy.
