The rates it uses
You can calculate at the 20% standard rate, the 5% reduced rate, or the 0% zero rate, so the breakdown matches the goods or services you are pricing.
Reading your result
The full breakdown shows the net amount, the VAT, and the gross total, whether you started from a net or a gross figure.

Frequently asked questions
What are the UK VAT rates?
The UK has a 20% standard rate on most goods and services, a 5% reduced rate on items such as domestic energy, children's car seats, and mobility aids, and a 0% zero rate on most food, books, newspapers, children's clothes, prescriptions, and public transport.
How do I remove VAT from a gross amount?
Divide the gross amount by 1 plus the rate. At 20% the net is gross divided by 1.2, and the VAT is the difference. For example, 120 GBP including 20% VAT is 100 GBP net plus 20 GBP VAT. This calculator does that for you when you choose remove VAT.
What is the difference between zero-rated and exempt?
Zero-rated goods are taxable at 0%, so a VAT-registered business can still reclaim the VAT on its costs. Exempt goods (such as insurance, postage stamps, and some property) are outside VAT, so businesses cannot reclaim the VAT on related costs. This calculator covers the rated supplies (20%, 5%, and 0%).
When does a business have to register for VAT?
A business must register for VAT once its taxable turnover passes the 90,000 GBP threshold in any rolling 12-month period, or if it expects to pass it in the next 30 days. Below that, registration is voluntary.
