Built with the same profit formula used in Privy’s Chrome extension
This calculator shows IF a product is profitable. Privy shows if it’ll actually SELL.
A product can have great margins and still be a terrible buy—because demand is low, competition is brutal, or the market price has crashed. Before you commit to buying stock, check demand with our free eBay sell through rate calculator — it shows what percentage of listings actually result in a sale.

Every eBay sale in the UK gets hit with two types of fees. This calculator accounts for both, so the profit number you see is what actually lands in your pocket.
Total received means the sale price plus any buyer-paid shipping. Both fees are calculated on that full amount.
This is the same formula used inside the Privy Chrome extension →Before your item cost and shipping
In 2026, eBay charges a final value fee of 12.9% on the total amount the buyer pays (including any buyer-paid shipping). On top of that, there’s a payment processing fee of 2.9% plus a fixed £0.30 per transaction. So on a £50 sale, you’d pay roughly £8.40 in total fees before factoring in your own shipping costs.
Start with the total amount received (sale price + buyer shipping). Subtract eBay’s 12.9% final value fee, the 2.9% + £0.30 payment processing fee, and your shipping costs. That gives you net revenue. Then subtract your item cost to get your actual profit. The calculator at the top of this page does all of this for you instantly.
eBay’s final value fee in the UK is 12.9% of the total transaction amount. This is calculated on the full amount the buyer pays, including any buyer-paid shipping. This fee is deducted automatically from your payout. Some categories have different rates, but 12.9% covers the vast majority of items most resellers deal with.
Yes, eBay adds 20% VAT on top of their fees for UK sellers. However, the 12.9% and 2.9% rates used in this calculator are the standard rates most private and small business sellers see on their invoices. If you’re VAT registered, you can reclaim the VAT on eBay fees as an input. Always check your eBay fee invoice for the exact breakdown on your account.
On a typical UK sale, eBay takes approximately 15.8% plus £0.30 in combined fees. That breaks down as 12.9% final value fee plus 2.9% payment processing fee plus a fixed £0.30. For example, on a £100 sale with free shipping, you’d pay about £16.10 in total eBay fees, leaving you with £83.90 before deducting your item cost and shipping.
