See your expected take-home on every major UK marketplace before you decide where to list an item — eBay, Etsy, Vinted, Depop, Amazon, TikTok Shop and Whatnot, with 2026 UK fees and VAT built in.
How MarginWise works: enter your item cost, sale price and postage once. MarginWise applies each marketplace's published UK fee structure and ranks platforms by net profit, margin and ROI so you can list where you keep the most.
Marketplaces supported: eBay (private and business), Etsy UK, Vinted, Depop, Amazon UK (Individual and Professional), TikTok Shop UK, Whatnot, StockX, Gumtree and Facebook Marketplace.
Fees and costs included: final value and commission fees, payment processing, per-order and listing fees, regulatory operating fees, subscription costs, postage to you and to your buyer, item cost, and VAT on fees where it applies.
Why profit differs between marketplaces: each platform charges a different mix of percentage and fixed fees, some charge buyers rather than sellers, and postage can be fee-bearing on one platform and free on another — so the best-paying marketplace changes with the item and price.
Free to use with no sign-up: MarginWise is completely free, needs no account, and runs unlimited comparisons in your browser.
