What will you actually keep?

Nothing from you. The buyer pays a Buyer Protection fee (roughly 30–80p plus around 5%) on top of your asking price, so if you list a jumper at £15 you receive £15, minus whatever the postage label costs if you're not using Vinted's included label.

It depends on whether you're a private or business seller. For UK private sellers, standard selling is free in most categories — no final value fee, no regulatory operating fee. Exclusions and optional charges still apply (vehicles, listing upgrades, some international sales). Business sellers pay a category-based fee plus a per-order fixed charge; there isn't a single percentage that fits every business seller, so enter your applicable rate in the fee field.

There's no Depop selling fee any more. You pay payment processing of 2.9% + £0.30, calculated on the item price plus postage where you're charging for it. If you switch on a Boosted Listing, Depop's current UK boost fee (8% of the sale) is added on top — that's optional and off by default in the calculator.

If you're deciding whether reselling is worth continuing, absolutely. A £4 net profit sounds fine until you realise it took 40 minutes of photographing, listing, packing and a Post Office trip — that's £6/hour. The £/hour figure is often the number that actually changes behaviour.

Only if you enter it. If the buyer paid postage (Vinted's default), flip the toggle to 'Buyer paid' and it drops out of your cost side.
