How to price an eBay item to hit a target profit
Most sellers price forwards: pick a number, list it, work out afterwards whether it made money. It is the wrong direction. If you know what an item cost and what profit you need, the price is a calculation — not a guess you check later.
The calculation, backwards
Forwards you ask: I am listing at £22 — what do I make?
Backwards you ask: I paid £9.51 and I want £5 — what do I list at?
The second is the question you actually have when you are about to list, and it is the one almost no calculator answers.
It is harder than it looks, because the fees depend on the price. Raise the price and the final value fee rises with it, so you cannot simply add your costs and your target together. The sum has to be solved, not added.
What goes into the price
Every one of these, or the answer is wrong:
- What the item cost you, including any delivery and tax you paid on the way in
- Your postage label
- eBay's four fees — final value, per-order, regulatory, and VAT on all three
- Your promoted listing rate, if you use one
- A returns allowance — if you absorb one return in thirty, that is roughly 3% off every sale
- The profit you actually want
Miss the returns allowance and your profitable items are only profitable until something comes back.
Know your break-even before anything else
The break-even price is where you make exactly nothing. Below it you are paying for the privilege of selling.
On our earlier example — £9.51 cost, £3.10 postage, 12.9% category — break-even lands around £12.06. That is the floor. Any discount, any markdown, any "let's shift it" decision needs to be measured against that number, not against the item's cost.
This is the figure to know before a sale event, not during one.
Working an example
You paid £9.51. Postage will cost you £3.10. You charge the buyer £3.50 postage. You want £5 profit.
Solving it with a 12.9% category and the full UK fee stack gives a list price of about £18.01.
Notice what happens if you had guessed: £15 feels reasonable and leaves you roughly £2.50 — half what you wanted. £22 leaves you £8.36, comfortably above target, but may not sell. Neither is a decision; both are guesses.
Pricing for a margin rather than an amount
Some sellers prefer a percentage. It works, with one warning: percentage margins on cheap items are misleading. A 30% margin on a £6 item is £1.80, and a single return wipes out five of them.
On low-value stock, a minimum cash profit per unit is usually a better rule than a percentage. Below a certain figure the item is not worth the picking, packing and risk, however good the percentage looks.
What to do when the number comes out too high
Sometimes the maths says £18.01 and the market says £14. That is useful information, not a failure. Your options:
- Source it cheaper — the only change that improves every future sale of that line
- Cut the postage cost — often the easiest win, and it does not touch the price
- Drop the promoted listing rate on thin-margin items
- Accept less profit, deliberately, knowing what you are accepting
- Do not list it — a legitimate answer that sellers reach for far too rarely
The value of doing the calculation first is that you choose. Pricing forwards means finding out three months later that a line never worked.
Repricing when costs move
Your supplier price will change and your listing will not notice. That is the most common quiet margin leak there is — nothing breaks, profit just gets thinner.
A practical habit: whenever you restock, re-run the calculation. If the supplier price moved, the listing price probably should too.
Do it in two minutes
Our eBay fee calculator does this directly. Switch it to Profit → Price, enter what you paid and the profit you want, and it returns the price to list at with the full UK or US fee stack already accounted for — plus the break-even figure you should never go below.

Frequently asked questions
How do I work out what to sell an item for on eBay?
Start from what it cost you and the profit you want, then add every fee and your postage. Because eBay's fee rises with the price, the calculation has to be solved rather than simply added up — which is what a reverse calculator does.
What is a break-even price?
The price at which you make exactly nothing after all costs and fees. Anything below it loses money. Know it before you discount.
What profit margin should I aim for on eBay?
It depends on category and how you source. On low-value items, a minimum cash profit per unit is usually a more useful rule than a percentage, because a 30% margin on a cheap item does not survive one return.
Should I include returns in my pricing?
Yes. If you absorb roughly one return in thirty orders, that is about 3% off every sale. Price it in or your good sales are quietly funding your bad ones.
How often should I review my prices?
Whenever you restock. Supplier prices move and listings do not follow automatically, which is the most common reason margins thin out without anyone noticing.
