How to review Amazon UK FBA and MCF fee changes

Amazon fees depend on the product, dimensions, weight, programme, fulfilment route, storage profile and current seller terms. This article does not reproduce or forecast rates.

Use Amazon Seller Central and the fee preview available to the connected account. Record the exact document or calculator result and its capture date before making a commercial decision.

Build a dated input sheet

For each representative SKU, record:

• product category and selling price;
• packed dimensions and weight;
• current FBA or MCF fee preview;
• storage, removal and other applicable programme charges;
• direct fulfilment and carrier costs from the actual account; and
• the VAT and tax basis approved for the comparison.

Do not apply one SKU's result to a whole catalogue.

Separate FBA, FBM and MCF

FBA inventory, merchant-fulfilled inventory and Multi-Channel Fulfilment serve different order routes and can carry different records and charges. Model each route separately. Confirm current service eligibility and delivery options in the seller account.

Test operational alternatives

Where stock is held in more than one location, compare available fulfilment routes using representative orders. MaxInvent can model warehouses and locations, but it does not claim nearest-warehouse auto-routing. Carrier workflows are Evri, Amazon Shipping where eligible and Temu shipping within eligible Temu orders; other carriers require assessment against account and API availability.

Recalculate when evidence changes

Repeat the comparison when Amazon publishes new terms, a product changes category or packaging, or your storage and carrier costs change. Keep the old and new source evidence so the pricing decision can be reviewed.

No typical fee increase, saving, stock split, target margin or customer outcome is claimed here.
