To set an Amazon FBA price on amazon.co.uk, work out what each sale costs, find the buyer-facing price that covers those costs, then add room for the margin you want. If you first need to know what Amazon charges, read the FBA fulfilment fees guide and Amazon selling fees guide. This guide focuses on turning your costs into a workable price, not explaining the fees again.
A useful pricing decision has three checkpoints: a break-even price, a practical floor below which you would normally avoid selling, and a target price that supports your business. Check all three against the prices buyers can actually see on amazon.co.uk.
Build a cost list for each unit sold
Start with a product and a realistic estimate of the costs attached to selling one unit. Include:
- Landed product cost: what you pay for the item, plus its share of freight, import costs, preparation and packaging before it is ready to sell.
- Referral fee: use the fee that applies to the product and the selling price you are testing.
- Fulfilment fee: check the estimate for the product as it will be packed and sold.
- Storage: allocate an expected storage cost to each unit rather than treating inventory held at Amazon as free.
- Advertising: estimate what you can afford to spend to acquire an order. Keep an allowance even if a campaign has not started yet.
- Returns: allow for the expected cost of refunds, unsellable stock and handling. Do not assume every returned item can be resold.
If other operating costs need to be recovered through each sale, add an appropriate allocation. Keep the assumptions beside your calculation: advertising and returns are estimates, while storage changes with how long stock remains unsold. You can check the Amazon fee inputs with the fee calculator and use the profit calculator to test how the combined costs affect a proposed price.

Make the price work with VAT
The price a UK buyer sees on amazon.co.uk needs to be considered as a buyer-facing price, including VAT where applicable. If your business is VAT-registered, do not treat the whole amount the buyer pays as revenue you can keep. Check the VAT treatment of the product and your costs, and compare profit using consistent VAT-inclusive or VAT-exclusive inputs. Otherwise, a price that looks profitable at checkout may not deliver the margin you expected.
If you are not VAT-registered, do not simply copy a VAT-registered competitor’s calculation. Your circumstances and recoverable costs may differ. The VAT calculator can help you examine the VAT element of a proposed price; confirm your own treatment with your accountant or HMRC where needed. Keep your final comparison anchored to the price the buyer will see.
Find break-even, then set a floor and a target
Use this sequence rather than choosing a price because it looks competitive:
- Calculate break-even. Enter your per-unit costs and test a buyer-facing price at which the proceeds left after applicable VAT and costs cover those costs, with no planned profit. Use the break-even calculator to explore this point.
- Choose a floor. Decide the lowest price you would normally accept after allowing for uncertainty in advertising, returns and other variable costs. A floor set exactly at estimated break-even leaves no cushion when an assumption proves optimistic.
- Set a target. Add the profit you need to sustain the product and check the resulting margin with the margin calculator. Test the target again in the profit calculator before making it your listing price.
Check the calculation again whenever you change the proposed price. A price-linked cost, such as the referral fee, may change with it, so adding a desired profit to a previous break-even result is not always enough. Record which assumptions produced your floor and target so you can revisit them without rebuilding the calculation from memory. The tools hub brings the calculators together if you need to compare scenarios.
Compare your target with competing offers
Search amazon.co.uk for the product and examine comparable offers, not just the cheapest visible price. Check whether the item, condition, pack size, delivery proposition and listing quality are genuinely similar. A price that works for another seller may not work with your landed cost, advertising spend or expected returns.
Look at which offer is featured in the Buy Box and how competing offers are presented, but do not assume matching or undercutting a price will win it. If your target is well above comparable offers, revisit your costs and product proposition before cutting your price. If the market price falls below your floor, consider whether this product remains viable rather than selling at a loss to stay visible.
Review prices when the assumptions change
Pricing is a repeatable check, not a decision you make only when you create the listing. Recalculate after Amazon fee changes, a new supplier or freight cost, changes in advertising performance, or a shift in returns. Review ageing stock as storage costs accumulate, and plan for seasonal changes in demand rather than relying on last season’s price.
When you review a price, update the cost list first, then recalculate break-even, the floor and the target. Finally, check current comparable offers. That order helps you distinguish a price you can charge from a price that still makes commercial sense for your FBA product.
