About Seller Profit
Independent Vinted calculators built by a UK seller, for UK sellers.

Founder, Seller Profit
Vinted seller since 2021
Hi, I'm Alex. I started selling on Vinted back in 2021 - originally just to clear out a wardrobe full of clothes I hadn't worn in years. I listed a few things, made a couple of hundred quid, and thought “that's it then.”
Except it wasn't. I started noticing that certain items sold incredibly quickly. A North Face jacket I'd picked up for £8 at a charity shop went for £45 in under two hours. A pair of barely-worn New Balance trainers I found at a car boot sold for £32 before I'd even got home. The margins were genuinely shocking.
So I went from casual declutterer to deliberate reseller. I started tracking everything in a spreadsheet - what I paid, what I sold it for, packaging costs, time spent. Over the next 18 months, I quietly crossed £10,000 in total Vinted sales. Not because I had some secret formula, but because I was systematic about knowing my numbers.
The problem was that most of the “Vinted calculator” tools I found online were either wrong (Vinted charges sellers nothing - a lot of sites still get this wrong), out of date, or just not useful for UK sellers. Postage prices were wrong. Fee structures were guesses. Tax guidance was non-existent.
So I built Seller Profit - the tool I wish had existed when I started. Every calculator is based on Vinted's actual published documentation and UK HMRC guidance. Where information isn't published (like the exact buyer protection fee tiers), I flag it clearly rather than making something up.
The site is completely free. There are no sign-ups, no premium tiers, no upsells. Just honest tools for UK Vinted sellers.
The £10k journey
Spring 2021
First sale
Listed a Barbour jacket that had been sat in a bag for three years. Sold in 45 minutes for £55. I thought it was a fluke. It wasn't.
Summer 2021
First £500 month
Started visiting charity shops with intent. Learned which brands moved fast on Vinted - Ralph Lauren, The North Face, Levi's, Stone Island. Built a mental model of what was worth picking up.
Autumn 2021
Discovered the postage advantage
Realised that Vinted's integrated shipping - where the buyer pays - fundamentally changes the maths compared to eBay. On eBay I was subsidising postage. On Vinted, it's irrelevant to my profit.
Early 2022
Hit the HMRC threshold
Crossed the 30-sale mark that triggers Vinted's HMRC reporting. Spent an anxious weekend googling tax rules before understanding that the £1,000 trading allowance and the decluttering/trading distinction are quite sensible once you understand them.
Mid 2022
£5,000 total
Halfway there. By this point I had a proper system: photograph items in natural light on the same neutral background, price at 70–80% of the lowest eBay sold price, bump on Sunday evenings.
Late 2022
£10,000 total - and a website idea
Hit the milestone on a rainy Thursday afternoon when a vintage Levi's sherpa jacket sold for £85. Sat down that evening and started sketching out what would become Seller Profit.
