Try the calculators →Our mission
FeeFinderMate exists to simplify selling in the UK online marketplaces. Selling across Amazon UK, eBay UK and TikTok Shop can be profitable — but only if you understand the fees, taxes and hidden costs that eat into margins. Our mission is to give sellers—whether hobbyists, resellers, creators or small brands—the tools they need to calculate fees and net profit instantly, make better pricing decisions, and grow their businesses.
Why FeeFinderMate?
Marketplace fee structures vary: referral fees, final value fees, fulfilment (FBA) fees, royalty or commission cuts, payment processing deductions and VAT. That complexity causes mistakes and lost profit. FeeFinderMate collects the key fee elements and presents them in a fast, clear calculator designed for UK sellers.
Accurate fee breakdowns
See referral fees, fulfilment & FBA estimates, final value and regulatory fees, shipping and VAT in one screen.
Compare platforms
Quickly compare net profit on Amazon UK vs eBay UK vs TikTok Shop before you list a product or promote it.
Designed for UK sellers
Default VAT assumptions and fee examples use UK standards (20% VAT where applicable). You can adjust VAT, shipping and other variables to match your actual costs.
Fast & free
No signup required for basic calculators — fast calculations to help you list and price products without delay.
