Amazon Seller Fee Calculator UK 2025/26

How Amazon UK Fees Work

Selling on Amazon UK involves several layers of fees that must be factored into your pricing strategy before you list a single product. Understanding each fee type is essential to calculating your true net profit margin and return on investment.

The referral fee is Amazon's primary charge — a percentage of the total sale price deducted from every transaction. This fee ranges from 6% (mobile phones) to 15% (most categories). It applies regardless of whether you are using FBA or FBM, and is charged on the total amount the buyer pays including any delivery charges.

The selling plan fee depends on which plan you choose. The Individual plan costs 75p per item sold with no monthly subscription fee — suitable for sellers moving fewer than around 33 items per month. The Professional plan costs £25/month but waives the per-item fee, making it cost-effective for any seller moving more than 33 units monthly.

If you use FBA (Fulfilment by Amazon), additional fulfilment fees apply per unit picked, packed, and shipped by Amazon. These start at £2.25 for small light items and increase with size and weight. FBA also includes customer returns handling, which is a significant operational benefit for high-volume sellers.

FBA vs FBM — Which is Better for UK Sellers?

Fulfilment by Amazon (FBA) means Amazon stores your products in their UK fulfilment centres, picks and packs orders, handles customer returns, and provides access to the coveted Prime badge. The Prime badge is a significant competitive advantage — research consistently shows Prime-eligible listings achieve 20–30% higher conversion rates than non-Prime equivalents.

FBA is typically the better choice when: your products are fast-moving (sell within 30–60 days to minimise storage fees), your items are small and lightweight (FBA fees are proportionally lower), and your selling price is above £15–£20 (fees represent a manageable percentage of revenue). It is particularly well-suited to sellers who want to scale without building their own logistics operation.

Fulfilment by Merchant (FBM) means you store, pack, and ship orders yourself. This is cheaper in direct fees but requires more operational infrastructure. FBM is typically better for: slow-moving, seasonal, or bulky items (avoids storage fees), very low-margin products where every penny of FBA fee matters, custom or made-to-order items that cannot be pre-stocked, and products with specialist packaging requirements.

A common strategy among experienced UK Amazon sellers is to use FBA for their top-selling, small, fast-moving SKUs while fulfilling slower or larger items via FBM. This hybrid approach optimises the trade-off between conversion rates and fee efficiency.

Individual vs Professional Selling Plan

New sellers frequently start on the Individual plan (75p per item) while testing their product range. The mathematics are straightforward: if you sell more than 33 items per month (£25 ÷ £0.75 = 33.3), the Professional plan at £25/month saves you money. Most serious sellers switch to Professional within their first few months.

The Professional plan also unlocks additional features that are not available to Individual sellers: ability to apply for restricted product categories, access to advertising tools (Sponsored Products, Sponsored Brands), bulk listing upload via inventory files, and the ability to offer promotions and deals.

For new sellers testing a single product idea, the Individual plan is perfectly adequate initially. Once you are consistently moving more than 33 units per month across your catalogue, upgrading to Professional is an easy decision.

VAT for Amazon UK Sellers

VAT compliance is one of the most important — and frequently mishandled — aspects of selling on Amazon UK. The key rules for 2025 are as follows:

UK-established sellers must register for VAT once their taxable turnover exceeds £90,000 in any rolling 12-month period. Voluntary registration below this threshold is possible and can be beneficial if you sell to other VAT-registered businesses (they can reclaim your VAT, making your prices competitive).

Non-UK established sellers (including EU and rest-of-world businesses) have no registration threshold — they must register for UK VAT from their first sale to UK customers, regardless of value. Amazon has been collecting and remitting VAT on behalf of overseas marketplace sellers on goods up to £135 since January 2021, but sellers must still obtain a UK VAT number and file returns.

Amazon's fees are subject to VAT. For UK VAT-registered sellers, Amazon charges VAT on its fees, which you can then reclaim on your VAT return. This effectively makes Amazon fees tax-neutral for VAT-registered sellers.

Keep accurate records of all Amazon transactions, as HMRC increasingly uses data-sharing agreements with Amazon to cross-reference seller income with tax returns. All Amazon income must be declared — it is not sufficient to report only what you withdraw from your Amazon seller account.

Calculating True Amazon UK Profitability

Many new Amazon sellers underestimate their total costs by focusing only on the referral fee and FBA fee. A complete profitability calculation for an Amazon UK product must include:

• Cost of goods sold (COGS): Manufacturer/wholesale price, import duty, VAT on purchases, quality inspection costs
• Freight and logistics: Sea/air freight, inland transport, prep centre fees (if using a UK prep service)
• Amazon fees: Referral fee, FBA fee, monthly storage fee (calculated per cubic foot), long-term storage fee (if applicable)
• Advertising: Amazon PPC (Sponsored Products) typically adds 5–15% of revenue for new products gaining traction
• Returns provision: Budget 3–8% of revenue for returns, especially in clothing and electronics
• Selling plan fee allocation: Divide your monthly Professional plan fee by your unit sales volume

A common benchmark for Amazon UK private label sellers is a target of minimum 30% net margin after all fees and costs. Below this level, there is insufficient buffer for advertising spend, returns, and price competition. Products with 40–50% gross margins before advertising are considered strong candidates for Amazon FBA.
