Postage matters
Charging postage to the buyer is not the same as profit. Enter what you actually pay for postage, packaging and labels.
Clear CalculatorsSeller toolsHow to use the eBay profit estimate
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.
Promoted listings
If you use a promoted listing rate, enter the percentage so the estimate includes that extra cost.
Risk allowance
Use the return allowance if you want to set aside a small percentage for refunds, returns, claims or problem orders.
What the result includes
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.
Trust notes and limits
Last reviewed: 7 July 2026. This calculator is independent and does not use an eBay API. It does not know your account status, category, listing format, shop subscription, buyer fee display, VAT position, international sale settings, return outcome or final postage label price.
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.
Keep records
If you sell regularly, keep sale prices, postage costs, packaging costs, fees, refunds and receipts together. That makes profit easier to check later.
Do not ignore small costs
Tape, bags, labels, collection charges and printer costs can wipe out profit on low-value items.
Tax is separate
Casual selling and trading are different. This tool does not decide whether you need to report income or pay tax.
