About This Site

VAT Margin Calculator is a free tool built for UK businesses that buy and sell second-hand goods, antiques, works of art, and collectors' items under the VAT Margin Scheme. Our goal is to make VAT calculations simple, accurate, and accessible to everyone.

The calculator includes support for platform selling fees (eBay, Amazon, Etsy, Facebook Marketplace, Vinted) with full category breakdowns, a reverse price finder, CSV import/export, calculation history, and visual profit analysis.

This site is independently operated and is not affiliated with HMRC, eBay, Amazon, Etsy, or any other organisation mentioned. All fee data is researched from official platform documentation and is provided for guidance purposes only.

Disclaimer: This calculator is provided for guidance purposes only and should not be considered professional tax advice. While we strive for accuracy, VAT rules can be complex and subject to change. Always consult with a qualified accountant or tax advisor for advice specific to your circumstances. We accept no liability for decisions made based on this tool.
