Postage matters
Charging postage to the buyer is not the same as profit. Enter what you actually pay for postage, packaging and labels.
Enter the sold price, postage charged to the buyer, what the item cost you, and your real postage and packaging costs. Add a target profit if you want to know the listing price needed before accepting an offer.
For UK private selling, the default assumes no seller platform fee. If a seller fee applies to your listing, or you are using a business account, choose a fee profile and enter the percentage and fixed fee shown by eBay for that listing.
Charging postage to the buyer is not the same as profit. Enter what you actually pay for postage, packaging and labels.
If you use a promoted listing rate, enter the percentage so the estimate includes that extra cost.
Use the return allowance if you want to set aside a small percentage for refunds, returns, claims or problem orders.
The headline profit is the money received from the buyer minus item cost, postage cost, packaging, other costs, seller fee estimate, promoted listing estimate and return allowance. The target price shows the approximate item price needed to reach your chosen profit using the same assumptions.
The break-even sold price is the approximate item price needed before profit reaches zero. If your fee, postage or promotion assumptions are wrong, the profit, target price and break-even price will be wrong too.
Promotion is estimated on the sold price plus postage received, matching the basis explained by eBay's general campaign guidance. The estimate assumes the ad fee applies to this sale. It does not determine attribution or add taxes and buyer-facing charges to the fee base. Enter an effective rate including any VAT you bear. Target and break-even prices are rounded up to the next penny. Source and arithmetic checked 1 September 2026.
Last reviewed: 7 July 2026. Clear Calculators is not connected to eBay. Enter the fees shown for your own account, category and listing, and check the final postage and promotion costs before accepting the estimate.
Fee rules have changed for UK private sellers in recent years, and buyer-facing fees can affect what shoppers are willing to pay even where they are not a seller cost. Treat this as a planning tool, then check the final eBay listing and fee screen before listing, sending an offer or accepting a buyer offer.
If you sell regularly, keep sale prices, postage costs, packaging costs, fees, refunds and receipts together. That makes profit easier to check later.
Tape, bags, labels, collection charges and printer costs can wipe out profit on low-value items.
Casual selling and trading are different. This tool does not decide whether you need to report income or pay tax.
