Seller calculator

Work out whether an item is worth your time: profit, margin, break-even, and the most you should pay for a target profit.

Your numbers

These are your inputs, not our data: we don't know your real marketplace fees, postage, or how fast an item sells. Defaults (13% + £0.30) are typical eBay UK fees — check your own account.
