Include stock and fulfilment
Record what you paid for the item, plus the postage and packaging costs you expect to cover. If sourcing has a direct cost, decide how you will account for it consistently.
Before you list, work out what the sale needs to return after the costs you pay. A competitive price matters—but sales value on its own does not tell you whether a sale was worthwhile.
Start with the item cost, then add the costs you expect to pay to complete the sale: applicable eBay selling fees, postage, packaging, promoted listing costs if used, and any discount you plan to offer. Your break-even price is the point at which the money you keep covers those costs. To make a profit, price above that point.
Fee structures can depend on account type, category, listing format, optional upgrades and current eBay policies. Check the fee details shown in your seller account and eBay's current UK fee information rather than relying on an old percentage or a generic online example.

Use the actual fees and optional promotion costs that apply to your listing. Remember that discounts can reduce the amount you receive.
Choose the lowest net amount you are willing to accept. This helps you judge offers and avoid discounting below your target.
Suppose an item sells for £50. The stock cost is £22, the applicable selling costs total £6, postage costs you £4 and packaging costs £1. The estimated profit is £17 before any other overheads or tax: £50 − £22 − £6 − £4 − £1 = £17.
This example uses made-up figures to demonstrate the calculation; it is not an estimate of current eBay fees. Replace every figure with your own transaction details.

Review the net profit after fees and costs—not just the sale price
Fixed-price listings and auctions can suit different products and levels of demand. Use comparable evidence and your own stock turnover to decide which approach fits the item; there is no single format that works best for every category.
