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.
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
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.
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.
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%).
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.
