About this tool
This page opens the VAT calculator with the United Kingdom's standard rate of 20% already filled in — enter an amount, choose whether it is net or gross, and the breakdown appears in one click.
The UK standard VAT rate has been 20% since January 2011 and still applies to most goods and services in 2026. It is not the only rate: a reduced 5% rate covers items like domestic fuel and children's car seats, and a zero rate applies to most food and children's clothing — you can type 5 or 0 into the rate field to check those.
Use add mode to put 20% on top of a net invoice amount, or remove mode to see how much VAT is inside a gross receipt (the tool divides by 1.20 rather than subtracting 20%, which is the mistake spreadsheets often encode). Everything runs locally in your browser with plain numbers in any currency.
Example. Adding 20 percent VAT to a net price of 100 returns VAT of 20 and a gross price of 120.
Limit. A single rate is applied to the whole amount, with no line-by-line mixed rates.
