BuyFloor – eBay UK Profit Calculator

Calculate eBay UK profit, margin, ROI and a conservative maximum buy price from your fees and costs—locally in Chrome.

Buy stock with a number, not a hunch. BuyFloor is a manual, local-first buying-ceiling tool for UK eBay resellers. Choose the category, enter the selling price you realistically expect and add your acquisition and fulfilment costs. BuyFloor then estimates the most you can pay while still meeting your own minimum profit, margin or ROI rule. Use it in Chrome's side panel while you source stock online. What the current release does: • Applies supported eBay UK business-seller category bands, order fees and the regulatory operating fee • Supports private-seller, seller-level, international-buyer and eligible Premium Service scenarios • Includes General campaign attribution, VAT on published business fees and a user-set return-risk buffer • Accounts for buyer-paid postage, acquisition cost, inbound and outbound postage, packaging and other costs • Shows estimated profit, margin, ROI, break-even sale price and a conservative buying ceiling • Explains the estimate with an inspectable fee-and-cost waterfall and dated official fee source • Saves one buying rule and up to five restorable decisions on this device • Copies a plain-text decision summary BuyFloor does not read eBay pages, research sold listings, determine market value or recommend a selling price. This release has no account, analytics, advertising or remote server. Calculation data stays in Chrome's local extension storage. Results are estimates based on the values and settings you enter. They exclude VAT on the sale itself, income tax and accounting treatment. Check important purchases against your own eBay account and the current fee table. eBay is a trademark of eBay Inc.
