Questions people ask

What fees does Amazon FBA charge?

A referral fee (usually 8% to 15% of the price), an FBA fulfilment fee per unit by size and weight, monthly storage, and on some items low-inventory or returns fees.

What is a good FBA margin?

Many sellers aim for 25% to 30% net after all fees and ads, and at least 100% return on the stock cost.

Do I include VAT?

In the UK, EU and Australia, if you are VAT or GST registered the tax comes out of your price, so enter the price without VAT.
