At 20%, a quick shortcut: the VAT inside any gross total is the total divided by 6. So a £120 total holds £20 of VAT and £100 net.

UK VAT: standard 20%, reduced 5%, zero-rated 0%. Zero-rated is not the same as VAT-exempt. A guide, not tax advice.

How to calculate VAT

To add VAT at the standard 20% rate, multiply the net price by 1.20. So £100 net becomes £120 gross, with £20 of VAT. For the 5% reduced rate, multiply by 1.05 instead. The general rule is gross = net × (1 + rate), whatever the rate.

Reverse VAT: work out the VAT in a total

When a price already includes VAT, divide the total by 1.2 to get the net figure, then subtract to find the VAT. There is a quick shortcut at 20%: the VAT inside any gross total is the total divided by 6. So a £120 gross price contains £20 of VAT and £100 net. Switch the calculator to Remove VATand it does this for you at any rate.

Frequently asked questions

How do you remove 20% VAT from a figure?

Divide the VAT-inclusive total by 1.2. The result is the net price. For example, £120 ÷ 1.2 = £100, so the VAT was £20.

What is the formula for calculating VAT backwards?

Net = total ÷ (1 + VAT rate). At 20% that is total ÷ 1.2. The VAT is then the total minus the net.

How do you work out the VAT in a gross total at 20%?

Divide the total by 6. A £120 gross price contains £20 of VAT, because the VAT is 20/120 of the total.

What is the current UK VAT rate?

The standard rate is 20%. A reduced 5% rate applies to items such as home energy and children's car seats, and some goods like most food and children's clothes are zero-rated at 0%.

What is the VAT registration threshold?

You must register for VAT if your taxable turnover over the last 12 months goes over £90,000. This threshold has applied since 1 April 2024.
