Estimate only, based on Amazon.co.uk's published UK rate card (referral fees, FBA fulfilment fees from Feb 2025) and 2025/26 UK VAT. Amazon updates its fees periodically and your exact FBA fee depends on the measured size and weight — always confirm in Seller Central.

Selling on Amazon means stacking fees: a referral fee on every sale, an FBA fulfilment fee if Amazon ships for you, a per-item or monthly selling-plan fee, and — if you're VAT registered — VAT on the sale itself. This calculator pulls them together so you can see the number that actually matters: what you keep per unit.

How Amazon seller fees work

Every Amazon.co.uk sale is hit by a stack of charges. Knowing each one is the difference between a payout that looks healthy and a product that actually loses money:

  • Referral fee. A commission on every sale — a percentage of the total price including any postage you charge, with a 25p minimum. Most categories are 15%; consumer electronics is around 7%, jewellery starts at 20%.
  • FBA fulfilment fee. If Amazon picks, packs and ships for you, a per-unit fee based on the item’s packaged size and weight — from roughly £2 for a light envelope to £11+ for bulky oversize. It’s independent of your selling price.
  • Selling plan. Individual costs 75p per item sold; Professional is £25 a month (ex VAT) with no per-item fee, paying off above ~33 sales a month.
  • Storage & the rest. Monthly FBA storage (charged on cubic volume), long-term storage surcharges, advertising and a 50p media closing fee on books, music and video all chip away further.

VAT for Amazon sellers

VAT is where Amazon sellers most often get caught out — both on what they owe and what they can claim back.

  • Registration. Once your taxable turnover tops £90,000 in any rolling 12 months you must register — and your Amazon sales count towards it.
  • Output VAT. Once registered, your price effectively includes 20% UK VAT, which you pay to HMRC. Tick “VAT registered” above and the calculator strips it out so your profit is realistic.
  • Reclaiming fee VAT. Amazon adds 20% VAT to its UK seller fees — if you’re registered, that input VAT is normally reclaimable, so the fees become a net cost.
  • Cross-border. Selling on Amazon EU, holding stock abroad or using the OSS scheme each bring their own VAT rules.

Getting marketplace VAT and settlement reconciliation right is exactly what our Amazon seller accountants do day in, day out.

In plain English

The terms, explained

New to this? Here’s what the words on this page actually mean.

Referral fee
Amazon’s commission on each sale — a percentage of the total price (item plus any postage you charge), with a 25p minimum. Most categories are 15%; electronics is lower, jewellery higher.
FBA fulfilment fee
A per-unit charge when Amazon picks, packs and ships your order through Fulfilment by Amazon. It depends on the item’s size and weight, not its price.
Selling plan
Individual costs 75p per item sold; Professional is a flat £25 a month (ex VAT) with no per-item fee. Professional pays off once you sell more than ~33 items a month.
Closing fee
An extra 50p charged on each media item (books, music, video, DVD) on top of the referral fee.
Net profit & margin
Net profit is what’s left after every fee, your product cost and VAT. Margin is that profit as a percentage of your net (ex-VAT) sale price.
FAQ

Amazon FBA fee & profit calculator — your questions answered

How much does Amazon take in fees in the UK?
On a typical product you’ll lose around 15% to the referral fee, plus an FBA fulfilment fee of roughly £2–£6 per unit if Amazon ships for you, plus either 75p per item (Individual plan) or £25 a month (Professional). On a £20 item sold via FBA that’s often £5–£6 before you’ve paid for the product itself. Enter your figures above for an exact breakdown.
What is the Amazon referral fee?
It’s Amazon’s sales commission, charged as a percentage of the total price (item price plus any delivery you charge the customer), with a minimum of 25p per item. Most categories are 15%; consumer electronics and computers are about 7%, while jewellery starts at 20%. The calculator applies the correct UK rate for the category you pick.
How are Amazon FBA fees calculated?
FBA fulfilment fees are based on your product’s packaged size and weight, not its selling price. Amazon measures the item, slots it into a size tier (envelope, parcel or oversize) and charges a fixed fee per unit. Storage fees are separate and charged on the cubic space your stock occupies each month.
Is the £25 Professional plan worth it?
The Professional plan costs £25 a month (ex VAT) but removes the 75p-per-item fee, so it pays for itself once you sell more than about 33 items a month. It also unlocks bulk listing tools, advertising and the Buy Box. Below that volume, the Individual plan is usually cheaper.
Do Amazon fees include VAT, and can I reclaim it?
Amazon adds 20% VAT to its UK seller fees. If you’re VAT registered you can reclaim that VAT, so the fee is effectively a net cost — but you also have to pay 20% output VAT on your sales. Tick “VAT registered” above and the calculator strips output VAT out of your revenue so the profit figure is realistic. Getting VAT right on marketplace sales is exactly where we help ecommerce sellers.
How do I work out my Amazon profit margin?
Take your sale price, subtract every Amazon fee, your product and shipping cost, advertising and (if registered) VAT — that’s your net profit. Divide it by your net sale price for the margin percentage. Many sellers are surprised how thin the margin is once FBA and VAT are included; this tool shows it instantly.
