Amazon FBA Costs in the UK: A Complete Beginner’s Breakdown

The short answer

The real cost of selling one FBA product is usually made up of:

• selling-plan costs
• Amazon referral fees
• FBA fulfilment fees
• storage
• the product purchase cost
• inbound delivery
• preparation, labelling and packaging
• returns, refunds and damaged stock
• advertising or promotions
• VAT and import costs where relevant
• removals, disposals or other inventory costs
• payment, currency and business overheads

Amazon itself says the cost of selling depends on the selling plan, product category, fulfilment strategy and other variables.^[1]

Amazon's seller-start guidance also separates account creation, VAT compliance, listing products and fulfilment as distinct parts of getting started.^[3]

The correct calculation is therefore product-specific. A fee estimate that works for a small, light product may be wrong for a large, heavy, seasonal, restricted or hazardous product.

1. Selling-plan costs

Amazon's UK pricing page currently lists two main selling plans. The Individual plan costs £0.75 per item sold, while the Professional plan costs £25 excluding VAT per month.^[1]

The Individual plan can suit a seller testing a small number of sales. The Professional plan can make more sense at higher volume or where you need features such as advertising, advanced reports, bulk listing tools, multiple users or access to certain categories. Amazon's own plan comparison should be checked before choosing.^[1]

Do not treat the plan fee as your main cost. It is only one part of the calculation, and both plans can also incur selling fees.

A simple monthly comparison is:

Individual plan cost = units sold × £0.75
Professional plan cost = £25 per month, excluding VAT

The break-even point on the headline plan charges is around 34 units per month, before considering the features or category access that may influence the decision. Use the current Amazon pricing page because Amazon can change plan terms.

2. Amazon referral fees

Amazon charges a referral fee on each item sold. The rate depends on the product category, and Amazon says most referral fees are between 8% and 15%.^[1]

The referral fee is normally calculated from the total sales price. Amazon explains that this can include the item price, shipping cost and gift-wrapping charges, subject to the applicable fee rules.^[1]

This means a product with a healthy-looking gross margin can become much less attractive after the referral fee is applied. Do not use one universal percentage for every product. Check the current category rate, minimum fee and any price-band rules that apply to the particular listing.

Some categories have reduced rates or different bands for lower-priced products. Amazon's current pricing information includes category-specific changes for areas such as Clothing, Home Products, Grocery, Pet Clothing and Food, and Vitamins, Minerals and Supplements.^[1]

For costing purposes:

Referral fee per unit = sales price × referral fee rate

For a £25 sale at a 15% referral rate, the assumed referral fee is £3.75 per unit. That is an illustration, not a promise that 15% applies to your product.

3. FBA fulfilment fees

FBA fulfilment fees cover the work involved in processing and sending an order. The amount depends on the product's size, weight, category, shipping weight and fulfilment route.^[1]

Amazon describes FBA as a programme covering storage, shipping and customer service. It also says that products are sent to fulfilment centres, where Amazon handles orders and after-sales activity.^[2]

Fulfilment is not one flat fee for all products. Before buying stock, confirm:

• the packaged dimensions
• the unit weight and shipping weight
• the size tier
• whether the product is standard-size or oversize
• whether it is dangerous goods or contains a lithium battery
• whether it qualifies for a reduced rate
• whether the inventory will be fulfilled domestically or through another programme

Amazon's current Low-Price FBA guidance says eligible products priced up to £20 in most categories can qualify for reduced fulfilment rates when they meet the applicable price, size, weight and category criteria.^[4]

Eligibility is not automatic for every product under £20. The product must meet the relevant conditions, and some categories have different thresholds or exclusions. Check the current rate card instead of assuming that a product qualifies.

Amazon also displays a fuel and logistics-related fulfilment surcharge for 2026. This is a useful reminder that published rates can change and that a calculator or spreadsheet needs to be reviewed when Amazon updates its fees.^[1]

4. Storage fees

FBA storage is charged separately from fulfilment. Amazon describes storage fees as being based on the space inventory occupies in its fulfilment centres, with charges calculated using the daily average volume of the properly packaged product.^[1]

Storage cost is affected by:

• product dimensions
• inventory quantity
• how long stock remains in the fulfilment centre
• product category
• seasonal rates
• dangerous-goods status
• inventory efficiency and sell-through

Storage is easy to overlook when a product appears small on a retailer's website. Use the packaged dimensions, not just the product dimensions. A bulky box can change the economics significantly.

Slow-moving stock can also create indirect costs. Money remains tied up, storage continues, the product may need a price reduction, and a seller may eventually pay to remove or dispose of inventory.

5. Returns, refunds and inventory outcomes

FBA reduces the amount of customer-service and dispatch work a seller has to do, but returns and refunds still affect the economics of the product.^[2]

Allow for:

• customer returns
• refund-related loss
• stock that cannot be resold as new
• damaged or incomplete units
• removal or disposal charges
• return processing or other applicable service fees
• time spent reconciling inventory and reimbursements

The correct allowance depends on the product. A durable household item may have a different return profile from clothing, electronics, cosmetics or products with compatibility questions.

Do not assume that a returned unit automatically becomes a full-value sale again. Use a cautious allowance until you have enough of your own data.

6. Advertising and promotions

Advertising is optional in many cases, but it can become part of the cost of making a sale. Amazon lists advertising as an optional programme that some selling partners may use.^[1]

Possible costs include:

• sponsored advertising
• coupons
• promotions
• discounts
• deal participation
• external traffic
• photography, listing or creative work

Keep advertising separate from the basic product margin. A product may be profitable before advertising and unprofitable after it. Conversely, advertising may be a deliberate customer-acquisition cost for a branded product, so the decision should be based on the business model rather than a universal rule.

7. Product and supply-chain costs outside Amazon

Amazon fees are only one part of the cost stack. Your landed cost should normally include:

• purchase price
• retailer or supplier delivery
• inbound delivery to your prep location or Amazon
• prep labour
• labels and packaging materials
• inspection or quality checking
• storage before shipment to Amazon
• customs clearance where relevant
• import VAT and Customs Duty where applicable
• currency conversion and payment fees
• insurance where appropriate

For online-arbitrage or retail-arbitrage stock, keep the product invoice and order confirmation. For wholesale or private-label stock, keep supplier documentation, product specifications and compliance records.

If goods cross a border, GOV.UK explains that an EORI number may be needed for movements involving Great Britain, Northern Ireland and other countries or territories.^[6] GOV.UK's import guidance also covers tax, duty, licences and certificates that may apply.^[7]

Do not assume that a supplier's quoted product price is the complete landed cost. Confirm who is responsible for transport, customs declarations, import charges and delivery into the fulfilment network.

8. VAT and the cost of cashflow

VAT is not just an extra line on a tax return. It can change the amount you charge, the value of costs you can recover, the cash you need to reserve and the way your FBA margin should be calculated. Your position depends on factors such as business establishment, taxable turnover, transaction type, stock location and fulfilment model.

### When might you need to register?

For a UK-established business, GOV.UK currently says VAT registration is required when taxable turnover exceeds £90,000 in the previous 12 months or is expected to exceed £90,000 in the next 30 days. Voluntary registration below the threshold is also possible.^[5]

That threshold is not a complete answer for every Amazon seller. HMRC's marketplace guidance distinguishes between UK sellers and overseas sellers, and sets out separate situations involving goods already in the UK, goods imported for UK customers and goods located in the EU and sold to Northern Ireland.^[11]

Using FBA does not remove the need to check the VAT position. Amazon's own VAT resource explains that sellers may have obligations in each country where they sell or hold stock, and says sellers remain responsible for their VAT compliance.^[9]

### VAT-inclusive versus net costing

When you compare products, decide whether your spreadsheet is using VAT-inclusive or net figures. Keep the treatment consistent across:

• selling price
• purchase invoices
• Amazon fees
• fulfilment and storage
• advertising
• delivery and preparation
• import VAT
• refunds and returns

A product can appear to have a strong margin if the selling price is treated one way and the costs another way. Make the VAT assumption visible beside the calculation rather than hiding it in a general percentage.

The SellerProfitGuide calculator is a screening tool, not a VAT return. It uses the numbers entered by the user and does not decide whether VAT is recoverable, which VAT scheme applies or how Amazon reports should be treated. If you are VAT registered, reconcile its assumptions to your accounting records before relying on the result.

### Input VAT and evidence

If you are VAT registered, the VAT treatment of business purchases and expenses should be supported by the relevant records and invoices. Amazon's VAT guidance describes the basic principle that VAT-registered businesses may recover VAT paid on eligible purchases and account for VAT on sales, subject to the applicable rules.^[9]

HMRC says VAT records should be complete, up to date and sufficient to calculate the VAT due or recoverable. VAT Notice 700/21 also says VAT-registered businesses must keep a VAT account and relevant business records, and that records are generally kept for at least six years.^[10]

Keep a clear record of:

• sales and refunds
• Amazon settlement and transaction reports
• Amazon fee invoices
• supplier invoices
• delivery and preparation costs
• import VAT and Customs Duty
• credit notes and adjustments
• VAT returns and working papers
• the VAT treatment used for unusual transactions

Do not assume that a retailer receipt, Amazon report or customs document answers every VAT question by itself. Keep the document and record how it was used in your bookkeeping.

### VAT and cash reserves

VAT can create a timing gap. You may pay VAT on stock, delivery or other costs before recovering it, while VAT collected on sales may need to be reserved for a later return. Stock held in FBA can also tie up cash before it is sold.

Build a cashflow view alongside the margin calculation. Track:

• cash paid for stock
• cash paid for inbound delivery and preparation
• VAT paid on purchases and imports
• Amazon settlement timing
• refunds and returns
• VAT payment dates
• software, accounting and other recurring costs

If you are unsure whether to register, which VAT scheme applies, whether a cost is recoverable or how marketplace reports should be treated, ask an accountant who understands marketplace businesses. Do not use a generic online calculator as a substitute for advice on your own records.

9. Business records and evidence

A profitable-looking spreadsheet is not enough if you cannot explain the figures later. GOV.UK says self-employed people must keep records of business income and expenses for their Self Assessment tax return.^[8]

Keep a record of:

• date and supplier
• product name and ASIN or EAN
• purchase quantity
• unit cost
• delivery and preparation cost
• Amazon sales and fee reports
• refunds and returns
• stock removals and disposals
• advertising spend
• VAT and import records where relevant
• the assumptions used in your buying decision

For each product, keep enough evidence to connect the purchase to the listing and the stock received. This is especially important where product identity, authenticity, compliance or category approval may later be questioned.

10. A worked example with VAT

The following is a simplified illustration for a VAT-registered UK seller. It assumes the sale, purchase and inbound/preparation costs are standard-rated at 20% VAT.^[12] It is not a forecast, a VAT return or tax advice. Product rates, supplier invoices and Amazon fee invoices must be checked individually.

Assumptions for 10 units:

• Customer sale price: £25.00 per unit, including VAT
• Buy cost: £8.00 per unit, including VAT
• Inbound and preparation: £1.20 per unit, including VAT
• Referral fee assumption: 15% of the £25.00 sale price, treated as a final cost input for this illustration
• Fulfilment: £4.50 per unit, treated as a final cost input for this illustration
• Other cost: £0.20 per unit, treated as a final cost input for this illustration
• Storage allowance: £0.30 total
• Advertising allowance: £0.80 total
• Returns allowance: £0.30 total

### VAT split

Customer cash received = £25.00 × 10 = £250.00
Net sales value = £250.00 ÷ 1.20 = £208.33
Output VAT in the customer price = £250.00 - £208.33 = £41.67

Gross stock purchase = £8.00 × 10 = £80.00
Net stock cost = £80.00 ÷ 1.20 = £66.67
Input VAT in the assumed stock invoices = £80.00 - £66.67 = £13.33

Gross inbound and preparation = £1.20 × 10 = £12.00
Net inbound and preparation = £12.00 ÷ 1.20 = £10.00
Input VAT in the assumed inbound and preparation invoices = £2.00

Illustrative net VAT before other eligible inputs = £26.33 (calculated using unrounded values)

The input VAT figures assume that the seller has valid VAT evidence and that the costs are recoverable under the applicable rules. The Amazon fee allowances in this simplified example are treated as final cost inputs, not as VAT-recoverable invoices. In a real calculation, replace them with the actual Amazon invoices and the VAT treatment confirmed by your accountant.

### Profit calculation after removing VAT from the sale and eligible costs

Net revenue = £208.33

Net variable costs:
Stock cost = £66.67
Inbound and preparation = £10.00
Referral fee allowance = £3.75 × 10 = £37.50
Fulfilment allowance = £4.50 × 10 = £45.00
Other cost allowance = £0.20 × 10 = £2.00

Fixed or total allowances:
Storage = £0.30
Advertising = £0.80
Returns = £0.30

Illustrative total costs = £162.57
Estimated operating profit before direct taxes = £45.77 (calculated using unrounded values)
Estimated profit per unit = £4.58
Estimated margin on net sales = 22.0%

The customer pays £250.00 in this example, but £41.67 of that is output VAT rather than sales income. The seller pays £92.00 in gross stock and inbound/preparation cash, with £15.33 of assumed input VAT included in those invoices. The simplified VAT balance before other eligible inputs is £26.33.

This example does not include a Professional selling-plan allocation, corporation tax, income tax, import charges, removal costs, currency fees, Amazon fee VAT treatment, other recoverable input VAT or general business overhead. It should therefore be treated as a screening example, not a final buying decision.

You can use the SellerProfitGuide Amazon FBA profit calculator to test assumptions, but keep the VAT rate, VAT-inclusive or net basis and recoverability assumptions visible. Replace estimates with current product-specific Amazon data and actual invoices before buying.

11. Break-even and maximum buy price

A useful calculation is the maximum product cost that still leaves room for your target profit.

Start with the expected sale price and subtract the costs that are not the purchase cost:

Maximum product cost =
Sale price
- referral fee
- fulfilment
- inbound and preparation
- storage allocation
- advertising allocation
- returns allocation
- other costs
- target profit

This is only useful if each assumption is realistic. A high maximum buy price produced by an optimistic sale price or low return allowance is not a safe buying limit.

When comparing products, test at least three cases:

• expected sale price
• lower sale price
• slower or more expensive outcome

If the product only works in the optimistic case, treat the margin as fragile.

12. How to keep FBA costs under control

• Measure the packaged product before buying a meaningful quantity.
• Use the current Amazon fee and revenue tools for the exact product.
• Keep separate allowances for returns, advertising and storage.
• Avoid buying restricted stock before confirming approval.
• Start with a quantity you can afford to hold.
• Monitor aged and slow-moving inventory.
• Review actual fees against the original estimate.
• Keep supplier invoices and order records organised.
• Recalculate when Amazon changes fees or the listing price moves.
• Do not let a spreadsheet hide a weak product identity or compliance position.

Final checklist

Before committing money to an FBA product, confirm:

• Have I selected the correct selling plan?
• Have I checked the referral fee for the exact category?
• Have I checked the current FBA fulfilment and storage assumptions?
• Have I measured the packaged dimensions and weight?
• Does the product qualify for any reduced FBA rate, and have I confirmed the conditions?
• Have I included purchase, inbound, preparation, returns, advertising and other costs?
• Have I checked VAT and import treatment?
• Do I need an EORI number?
• Am I allowed to sell the product and its condition?
• Can I provide the required supplier and product evidence?
• Can I afford the stock if it sells more slowly than expected?
• Does the product still work at a lower sale price?

If the answer to any important question is no, pause before ordering.

Final view

Amazon FBA costs in the UK are manageable only when they are treated as a complete system rather than a single Amazon fee. The product price, referral fee and fulfilment charge are visible, but storage, returns, VAT, imports, preparation and cashflow can decide whether the purchase actually works.

Use current product-specific information, keep the assumptions visible, and review the result before committing stock. A small, cautious test is usually more informative than a large order based on an optimistic estimate.
