How the calculation works
The calculator adds up everything the item cost you: the purchase price, Buyer Protection if you bought it on Vinted, your extra costs and any promotion. It subtracts that total from the selling price. Since Vinted takes no commission from private sellers, the selling price is also what you receive.
Three figures come out of it. Margin compares profit with the selling price: it tells you how much of each sale you keep. ROI compares profit with cost: it tells you what each euro invested brings back. Finally, the minimum price reverses the maths: from your total cost and your target margin, it gives you the floor you shouldn't go below, even when someone makes an offer.
Worked examples
Jeans found for €6 at a thrift store, washed for €1, resold for €25. Total cost: €7. Profit: €18. Margin: 72%. ROI: 257%. To keep at least a 60% margin, don't go below €17.50, which is €7 divided by 0.4.
A sweatshirt bought for €15 on Vinted to resell at €30. Buyer Protection adds €1.45 to the purchase price, so the cost is €16.45 before shipping. Profit: €13.55, margin: 45.2%, ROI: 82.4%. Leave the fee out and you would have counted on €15 profit and a 50% margin.
Same item, same costs, but sold for €20 instead of €30 after a few price drops: €3.55 profit and a 17.8% margin. The price you actually sell at matters far more than a few cents of fees.
Margin or ROI: which one should you watch?
They answer different questions. Margin helps you set prices and compare items at very different price points. ROI helps you compare purchases when your sourcing budget is limited: an item bought for €2 and sold for €10 has a 400% ROI, one bought for €40 and sold for €70 a 75% ROI, yet the second earns you €30 against €8.
Keep in mind what the numbers don't show: the time spent sourcing, photographing and shipping, and how long the item takes to sell. An item that sits online for six months ties up your cash, however good the margin looks on paper.
Common mistakes
Confusing margin and markup. Buying at €10 and selling at €20 is a 100% markup and a 100% ROI, but a 50% margin, not 100%. If you're aiming for a 50% margin, the minimum price is double your cost, not one and a half times.
Forgetting the small costs. Detergent, hangers, bags, fuel to get to the car boot sale: on an item sold for €15, one or two euros of extras quickly cost you several points of margin.
Treating a boost as free. If you promote a listing, what you pay is a selling cost like any other. Enter the amount the app charged you to see whether it paid off.
Pricing off the most expensive listing around. A listing isn't a sale. The only price that matters for your maths is what similar items have actually sold for.
Vinted margins: frequently asked questions
How do I calculate my margin on Vinted?
Add up your purchase price, extra costs and any promotion to get your total cost, then subtract it from the selling price: that's your profit. Divide the profit by the selling price to get your margin as a percentage.
Does Vinted take a commission on my sales?
Not if you're a private seller: you receive the price you set. The Buyer Protection fee is paid by the buyer. Promotion options are still paid if you choose them.
What's the difference between margin and ROI?
Margin compares profit with the selling price, ROI compares it with cost. An item bought for €10 and sold for €20 gives a 50% margin and a 100% ROI.
What price do I need for a 50% margin?
Divide your total cost by 1 minus the target margin. For a €12 cost and a 50% margin: 12 ÷ 0.5 = €24. The calculator does this for you on the Minimum price line.
Do I need to declare my reselling profits?
It depends on where you live. In France, impots.gouv.fr states that reselling goods bought for that purpose is taxable and must be declared, unlike occasionally selling your own belongings. This calculator isn't tax advice: check with your country's tax authority.
