Which UK marketplace has the lowest fees?

There is no universal answer. Rates vary by category, programme, account and contract. Enter your current terms and all relevant costs; the defaults are illustrative assumptions, not a ranking.

Does Amazon FBA cost extra on top of the referral fee?

FBA and storage charges are outside this simplified model. Add the current charges for your product and programme to the shipping or cost input, or use Amazon's official calculator.

How accurate are the Temu fee rates?

Temu rates can be contractual and are not assumed here. Temu remains uncalculated and excluded from all rankings until you enter the commission rate from your own seller terms.

Does this calculator include VAT on fees?

The calculator does not model VAT. Use one consistent basis for every input and confirm the correct treatment with your accountant.

Can I run all four marketplaces at once?

MaxInvent documents live commerce connectors for Amazon UK, eBay, Temu, TikTok Shop, Groupon and ClearanceFood. Update timing depends on each API. For eligible connected Temu orders, MaxInvent can request available services, create a shipment and retrieve its label.

How to use the comparison responsibly

This is a simplified scenario tool, not a quote or profitability forecast. Start with your sale price and costs, replace public assumptions with current account rates, and enter contractual rates where no public assumption is available.

Amazon UK referral fees

Amazon fees can vary by category, price threshold and fulfilment programme. The selectable values are calculation assumptions linked to Amazon Seller Central. This tool does not fully implement tiered fees, FBA, storage, advertising or refunds.

eBay UK final-value fees

eBay fees vary by category, seller account, subscription and optional services. Replace the default assumption with the current rate shown for your account and include advertising, international and other charges outside this model.

Temu UK commission

Temu rates can be contractual, so the calculator deliberately makes no universal commission assumption. Enter the rate from your own seller terms. MaxInvent documents an eligible Temu platform-label and own-courier workflow . Temu controls eligibility, services, prices and commercial terms.

TikTok Shop UK commission + transaction fee

TikTok Shop fees can vary by category and programme. Replace the default assumptions with current Seller Centre terms and add affiliate, advertising, fulfilment, refund and other costs that this simplified model excludes.

Defaults are illustrative assumptions linked to public seller pages where available. They may be incomplete or stale. Verify every input against current account and contractual terms before making a pricing decision. Marketplace names are trademarks of their respective owners.
