How much does Amazon FBA cost to get started in the UK? A clear 2026 breakdown of fees, inventory, and launch budget so you can plan with real numbers.
The short answer: the Amazon FBA cost to get started is far lower than most people fear, and far higher than the £25-a-month figure they see quoted online. You can open a Professional seller account for £25 (excluding VAT) per month. The real spend that decides whether your launch works sits in three places that have nothing to do with Amazon’s subscription: inventory, branding, and the budget you set aside to win those first sales.
We work with consumer brands every week who assume FBA is either nearly free or wildly expensive. Both assumptions lead to bad decisions. Underestimate and you run out of stock in week three. Overestimate and you never launch at all. This post gives you the actual numbers for selling on Amazon UK in 2026, broken down so you can build a budget you trust.
By the end you will know what every line on your FBA invoice means, roughly what a realistic first launch costs, and where the money genuinely matters versus where it does not.
What you actually pay to sell on Amazon FBA in the UK
Selling on Amazon UK splits into two cost types: what you pay Amazon, and what you spend to have a product worth listing in the first place.
Amazon’s own fees are predictable and published. They cover the right to list, a cut of each sale, and the cost of Amazon picking, packing, and shipping your orders. Everything else, your stock, your photography, your launch advertising, is yours to control. Most brands that struggle on Amazon do so because they planned for the first bucket and ignored the second.
Summary: Amazon’s platform fees are small and fixed, but your total FBA startup cost is driven by inventory and launch spend, which you control.
The selling plan: £25 a month, or £0.75 a sale
Every seller picks one of two plans. The Individual plan charges £0.75 (excluding VAT) per unit sold and suits anyone testing the water with a handful of orders. The Professional plan costs £25 (excluding VAT) per month no matter how many units you sell, and it is the one any real brand needs because it carries access to advertising, the Buy Box, bulk listing tools and brand features.
The maths is simple. Sell more than roughly 33 units a month and the Professional plan is cheaper. For a brand with genuine ambitions, treat the £25 as a fixed cost of doing business, not a decision to agonise over.
Summary: budget £25 a month for the Professional plan, or £0.75 per sale on the Individual plan if you are only testing.
Referral fees: Amazon’s cut of every sale
Amazon takes a referral fee on each item sold, calculated on the total price the buyer pays including postage. Most categories sit between 8% and 15%, with a per-item minimum of £0.25. Sell a £20 product in a 15% category and you hand Amazon £3 on that sale.
2026 brought real movement here. Amazon reduced referral fees in several categories, including Clothing and Accessories (down from 8% to 5% on items up to £15) and a new Home Products rate cut from 15% to 8% on items priced up to £20. If you sell lower-priced consumer goods, check the current Amazon UK fee schedule for your exact category before you set a price, because the rate you assumed last year may have changed.
Referral fees are not a startup cost in the cash-up-front sense. They are the single biggest ongoing cost most brands face, so factoring them into your unit economics now saves a painful surprise later.
Summary: expect to lose 8% to 15% of every sale to referral fees, with £0.25 the floor per item.
FBA fulfilment fees: paying Amazon to do the heavy lifting
This is what the “F” in FBA buys you. Send your stock to Amazon’s fulfilment centres and they store it, pick it, pack it, ship it, and handle returns and customer service. There is no subscription, no contract, and no minimum inventory for the fulfilment service itself. You pay per unit, based on size and weight.
A small, light product costs only a little over £1 to fulfil. A bulky or heavy one costs several times that, which is why product dimensions matter enormously to your margin. 2026 has been favourable to sellers here: Amazon cut average fulfilment fees and expanded its Low-Price FBA rates to products priced at or below £20, lowering fees on newly eligible items by an average of £0.40 per unit. A 1.5% fuel and logistics surcharge applies from 17 April 2026, so build a little headroom into your figures.
Summary: FBA fulfilment fees are charged per unit by size and weight, so smaller, lighter products protect your margin.
Storage, inventory, and the costs that actually add up
Amazon charges monthly storage on the space your stock occupies, billed per cubic metre, and is higher in the Q4 peak season. Send in twelve months of inventory and you pay to warehouse it. Send in too little and you risk stockouts that wreck your ranking. Getting that first order quantity right is one of the highest-leverage decisions a new seller makes.
The largest number on your startup budget is almost never an Amazon fee. It is the stock itself. Manufacturing or buying your first production run, plus shipping it into Amazon, is where most of the cash goes. A modest first order of a single product can run from a few hundred pounds to several thousand depending on your category, supplier, and minimum order quantity.
Then come the costs that separate a listing that sells from one that does not: professional photography, a properly written and optimised listing, and a launch advertising budget to buy visibility before organic ranking kicks in. Skimping here is the most common and most expensive mistake we see. A cheap listing on good stock loses to a good listing on average stock every time.
Summary: inventory, listing quality, and launch advertising, not Amazon’s fees, are where your startup budget is won or lost.
A realistic Amazon FBA startup budget for a UK brand
Putting it together, here is a sensible planning range for launching your first product properly rather than cheaply.
The fixed Amazon side is small: £25 a month for the Professional plan, plus referral and fulfilment fees that come out of each sale rather than your upfront cash. The variable side is where you plan. A first inventory order typically sits anywhere from £500 to £3,000+. Branding, photography, and a professionally optimised listing add a few hundred to roughly a thousand. A launch advertising budget of £500 to £1,500 over the first eight to twelve weeks gives a new product enough visibility to gather reviews and ranking.
Add those together and most UK consumer brands should plan for somewhere in the region of £2,000 to £5,000 to launch a first product the right way, with inventory the biggest and most variable line. You can start with less. The brands that build something durable rarely do.
Summary: budget roughly £2,000 to £5,000 for a serious first FBA launch, with inventory the largest single cost.
What to do next
Before you spend anything, model your unit economics on a single product. Take your expected selling price, subtract the referral fee for your category, subtract the FBA fulfilment fee for your size tier, subtract your landed cost per unit, and see what profit is left. If the number is thin before you have spent a penny on advertising, the product will not work at scale, and no launch budget fixes that.
Run the same exercise across your three or four strongest products and you will quickly see which one deserves your first order. New brands testing the water, rather than committing to a full agency engagement, often start with focused expert coaching to pressure-test those numbers and the launch plan before the money is committed. If you are weighing up whether to start at all alongside an existing job or business, our guide on whether you can start selling on Amazon while working full time is a useful companion to this one.
The bottom line
Getting started on Amazon FBA in the UK costs less than the headlines suggest and demands more discipline than the hype admits. The £25 plan is the easy part. Sound product selection, honest unit economics and a proper launch budget are what turn that £25 into a brand that compounds.
