What this means
Adding VAT at 20% to a net price of £100.00 gives roughly £20.00 of VAT, for an estimated gross (VAT-inclusive) total of about £120.00. These are rounded estimates to sanity-check against — confirm the exact figures for your own situation.
This is an estimate to help with your numbers — not financial or tax advice, and not a guarantee of any VAT liability. Based on 2025/26 VAT rates — check HMRC, as rates and rules change. VAT applies UK-wide.
