Formulas & VAT Mechanics

1. Net Selling Price (Ex-VAT) Net Price = Gross Selling Price / (1 + (VAT Rate / 100)) Example: A £24.00 item in the UK (20% VAT) has an ex-VAT net price of £24.00 / 1.20 = £20.00. (Subtracting 20% from £24.00 gives £19.20, which is incorrect).

2. VAT Remittance Due VAT Amount = Gross Selling Price - Net Selling Price This is the statutory tax collected from the consumer that must either be remitted by the seller (if VAT registered) or withheld and remitted by Amazon under marketplace facilitator rules.

3. Amazon Referral Fee Deduction Referral Fee = Gross Selling Price × Referral Percentage Amazon assesses referral fee percentages against the total gross transaction value paid by the buyer, not the net-of-VAT revenue.

Frequently Asked Questions

How is UK and EU VAT extracted from a gross Amazon selling price?

Because Amazon prices in the UK and EU are displayed inclusive of VAT, you must divide the gross price by (1 + VAT rate). For example, at a 20% VAT rate, divide by 1.20. Deducting a flat 20% from the gross price is mathematically incorrect and overstates VAT liability.

How does the UK £135 consignment rule affect marketplace sellers?

For consignments of £135 or less sold to GB customers through an online marketplace like Amazon by an overseas seller, the marketplace accounts for supply VAT at the point of sale. Above £135, normal import VAT and customs rules apply. Source: HMRC UK Government Guidelines.

Does Amazon charge referral fees on the VAT-inclusive or net price?

Amazon calculates its percentage referral fee on the total gross price paid by the buyer (including VAT and any shipping fees charged), not the net-of-VAT amount. Our calculator accurately reflects this fee structure.

Can I edit the standard VAT rate in this calculator?

Yes. While default rates are provided (UK 20%, Germany 19%, France 20%, Italy 22%, Spain 21%), the VAT rate input field is fully editable to accommodate reduced rates (such as 5% or 7% for eligible books, food, or children's items).
