eBay Profit Calculator UK
Use this eBay fee calculator UK guide to estimate profit margin, break-even price, promoted listing fees, postage and packaging costs, or a potential dropshipping profit.
This is not an official eBay calculator. It estimates UK business seller fees using the category you select, the published per-order fee, and the 0.35% regulatory operating fee. Always check your actual eBay transaction fees.
Calculate your estimated profit
Enter the figures for one sale. Results update automatically, and blank fields are treated as zero.
How it works
A clear estimate from your own figures
The calculator adds the selling price and buyer postage to get total revenue. It applies the selected category's final value percentage, a £0.30 order fee for orders of £10 or less or £0.40 above £10, and the 0.35% regulatory operating fee.
Published tiered rates and selected reduced-order-fee exceptions are included. Promoted listing and entered selling costs are then added before profit, break-even price, and target price are estimated.

Before you rely on the result
- Select the exact published subcategory exception when one applies.
- Include packaging, labels, and other per-order costs.
- Allow separately for taxes, international fees, seller-performance surcharges, discounts, returns, refunds, or overheads when relevant.
- Recheck fees whenever marketplace rules change.
Practical tips
Improve the quality of your estimate
Track small costs
Mailers, tape, labels, inserts, and handling materials can reduce margin across many orders.
Test promoted rates
Try different promoted listing percentages to see how they may affect estimated profit.
Common mistakes
Costs sellers often forget
Using the buyer's postage charge
The amount a buyer pays is revenue. Enter the carrier's actual charge separately so postage does not appear as free profit.
Ignoring returns and overheads
A one-sale estimate does not include every return, refund, subscription, storage cost, tax, or hour of work. Allow for those in your wider business planning.
Choosing the wrong fee category
Category rates and exceptions can differ. Select the closest published category and compare the estimate with a real transaction before relying on it.
Common questions
eBay profit calculator FAQ
How do I calculate eBay profit in the UK?
Add the money received from the sale, then subtract the item cost, postage, packaging, marketplace fees, promotion fees, and other sale-related costs.
Does this calculator include promoted listing fees?
Yes. Enter a promoted listing percentage and the calculator estimates that fee from total revenue. Use zero if the listing is not promoted.
Are the eBay fee results exact?
No. The calculator follows the published UK business seller category, order, and regulatory fee structure, but account discounts, performance surcharges, international fees, taxes, listing conditions, and future fee changes can affect the real charge.
What is a good profit margin for eBay sellers?
There is no single margin that suits every product. The right target depends on returns, overheads, time, stock risk, and business goals.
