"You can start Amazon FBA with nothing" and "you need thousands" are both wrong. The honest number depends on your model, but for a UK beginner doing arbitrage it's a lot less than most guides imply. Here's a realistic breakdown of the real startup costs in 2026 — and the cheapest sensible way to begin.
The costs, one by one
1. Amazon seller plan.
- Individual: £0 per month, ~£0.75 per item sold — right for testing.
- Professional: ~£25/month + VAT, no per-item fee — worth it once you sell more than ~35 items/month.
Start Individual; upgrade when the maths flips.
2. Stock (your main cost). For arbitrage, this is where your money goes — and you control it. Many UK sellers start with £100–£300 of clearance stock, buying a few units each of several products. Because each buying decision is only a few pounds, your risk is spread.
3. Tools.
- A scanner/profit app: there are genuinely free options (including Axivelo's free 10-scans-a-day tier), so this can be £0 to start; paid tools run from a few pounds a month.
- The free FBA calculator costs nothing.
4. Prep and shipping to Amazon.
- Prep — labels, poly bags, boxes: a few pounds to start; more if you use a prep service.
- Shipping stock into Amazon (FBA): typically well under £1 per unit on a sensible box.
Budget a small buffer (say £20–£50) for your first shipment's prep and postage.
5. Fees you pay later (not upfront). Referral fees, FBA fulfilment fees, storage and VAT come out of each sale, not your startup budget — but they decide profit, so factor them per product. See Amazon FBA fees explained.
A realistic starter budget
| Item | Cost (beginner, arbitrage) |
|---|---|
| Seller plan | £0 (Individual) |
| Starter stock | £100–£300 |
| Scanner app | £0 (free tier) – a few £/mo |
| Prep + first shipment | £20–£50 |
| Total to start | ~£150–£400 |
You genuinely can begin at the lower end and reinvest profits — that's the appeal of arbitrage over models that need big upfront inventory.
Why arbitrage is the cheapest way in
Compared with the alternatives, arbitrage minimises upfront risk:
- Retail/online arbitrage: ~£150–£400, low risk per decision.
- Wholesale: more capital (bulk buys, supplier minimums).
- Private label: often £2,000+ (inventory runs, branding, samples, sometimes ads).
If your goal is to start cheaply and learn Amazon's real fees on real products, arbitrage is the sensible entry — see what retail arbitrage is and the step-by-step guide.
The cost that actually hurts: bad buys
The biggest drain on a beginner isn't the seller plan or prep — it's buying stock that won't sell or won't profit. £200 of the wrong products is a far bigger loss than any subscription. That's why the money-saving move is checking every product's profit, demand and competition before you buy. Axivelo does that from a barcode scan — net profit, ROI, your maximum buy price and demand on one screen — so your starting budget goes into stock that actually moves. Free to start on Android.
Budget the entire first cycle, not just stock
Consider a hypothetical £300 starting pot. Put £160 into ten verified units at £16 each, reserve £35 for inbound shipping and packing, £25 for unexpected returns, and leave £80 unspent for a replacement deal or delayed payout. That allocation is a discipline, not a recommended minimum: your actual inbound charge and capital at risk depend on the products and shipment. If just two units remain unsold, the tied-up stock cost is £32 and the first payout may be too small to repeat the purchase. Account for your time as well as cash if you want to compare this to a side job.
Amazon currently lists an Individual plan of £0.75 per unit sold and a Professional plan of £25 per month excluding VAT, before referral and fulfilment fees. Dividing £25 by £0.75 gives roughly 34 sales, but plan-specific features and tax treatment matter too; the “cheapest” option can differ by your workflow. Amazon's Revenue Calculator lets you model the actual product and fulfilment method. Never treat an advertised sale price as a profit figure. Before the first order, establish listing eligibility and reserve enough money for slow stock and returns.
Why the cash cycle matters more than a headline budget
Your investment leaves your bank before sales proceeds return. First you buy stock; then you may pay for packaging and shipping into a fulfilment centre. The stock must be received, listed and sold, and Amazon's disbursement timing and reserves can delay available cash. A profitable unit can therefore still cause a cash squeeze if you put every pound into inventory. Think in batches: how many units can be unsold for a month without preventing your next sourcing trip? If your answer is “none,” reduce the first order or increase your reserve.
Returns make this real. On a hypothetical £5 profit per successful sale, one returned or damaged £20 item can consume several sales' gains. That does not mean avoid Amazon; it means choose test quantities that let you learn category-specific return rates and the true cost of prep and inbound freight. Track money paid, money owed, unsold stock at cost, and fees actually charged. A spreadsheet with one row per ASIN can show the gap between projected and realised profit without buying another subscription.
Three ways to trial a small budget
- Research-only: set up the account, check listing eligibility and calculate five live ASINs. Buying nothing while you learn is a valid first week.
- Low-volume merchant fulfilment: if the item permits FBM and you can fulfil reliably, try one unit without committing a shipment to FBA. Include your own postage, labour and returns.
- Small FBA batch: test a few verified units, add all inbound costs and keep a reserve. Replenish only if realised net proceeds support the next batch.
Check the current Amazon plan pricing and the ASIN-level fee estimate immediately before deciding. Any “start with £100” or “start with £1,000” promise without the unit economics and a reserve is just a guess.
Check any product before you buy
The free UK Amazon FBA calculator applies the 2026 fees and VAT to show net profit, ROI and margin. Axivelo does the same from a barcode scan in the aisle — free to start on Android.

How much money do you need to start Amazon FBA in the UK?
For retail or online arbitrage, realistically around £150–£400 — mostly stock (£100–£300), plus small prep and shipping costs, with the seller plan free on Individual and free scanner tools available. Private label needs far more, often £2,000+.
Can you start Amazon FBA with no money?
Not quite — you need some stock to sell. But you can start very cheaply: the Individual plan is free (about £0.75 per item sold), scanner tools have free tiers, and you can begin with a small amount of arbitrage stock and reinvest profits.
Is Amazon FBA cheap to start in the UK?
Compared with most product businesses, yes — arbitrage lets you start with a few hundred pounds and low risk per decision, because you buy a few units of many products rather than a big inventory run. Wholesale and private label cost considerably more.
What's the biggest cost of starting Amazon FBA?
For arbitrage sellers it's stock — and specifically, buying stock that doesn't sell or profit. That's a bigger risk than any subscription, which is why checking each product's numbers before buying is the most important cost-control habit.
