Standard rate: 20%. This is the headline UK VAT rate, unchanged since 4 January 2011. It applies to most goods and services.
Reduced rate: 5%. Applies to domestic energy and fuel, children's car seats, some energy-saving home renovations, and a few other categories.
Zero rate: 0%. Applies to most food (but not catering or takeaway), books and newspapers, children's clothes and shoes, and a number of other items. Zero-rated is still VAT-able, just at 0%, which is different from "exempt".
Registration threshold: £90,000. If your taxable turnover over any rolling 12 months exceeds this, you must register for VAT within 30 days of the end of that month. The threshold was raised from £85,000 to £90,000 on 1 April 2024 and is unchanged for 2026.
Deregistration threshold: £88,000. You can deregister if your taxable turnover falls below this.
Multiply the net price by 1.20 for the standard 20% rate. Example: £100 multiplied by 1.20 equals £120 gross. The £20 difference is the VAT amount. Use the calculator above for any amount, instantly.
Divide the gross price by 1.20 to find the net amount at 20% VAT. For the VAT portion alone, multiply gross by 1 divided by 6. Example: £120 divided by 1.20 equals £100 net. Use the Remove VAT tab above.
The standard UK VAT rate is 20%, unchanged since 4 January 2011. Reduced rate of 5% applies to domestic energy and some renovations. Zero rate (0%) covers most food, books, and children's clothing. See GOV.UK for the full list.
You must register when your taxable turnover exceeds £90,000, the threshold set by HMRC since 1 April 2024. You can also register voluntarily under that threshold to reclaim VAT on business purchases. Always verify the current threshold with HMRC before acting.
addvat.co.uk is a free, single-purpose UK VAT calculator. It handles both directions of the VAT calculation: adding VAT to a net (ex-VAT) price to reach the gross amount a customer pays, and removing VAT from a gross price to find the net amount and the VAT element. It supports the standard UK rate of 20%, the reduced rate of 5% (applied to domestic energy, children's car seats, and certain other goods), the zero rate, and any custom percentage. All rates are verified against HMRC's published guidance. The tool runs entirely in your browser; no figures are transmitted or stored.
Useful for sole traders, small businesses, and anyone checking whether VAT has been correctly applied to an invoice, receipt, or quoted price. All calculations happen in your browser. Nothing you type is sent to a server.
For guidance only. This tool does not constitute professional tax advice. For complex VAT situations, speak to a qualified accountant or contact HMRC.
