UK VAT Explained
Value Added Tax (VAT) is charged at 20% on most goods and services in the UK. If you are VAT-registered, you charge VAT on your sales and reclaim VAT on business purchases. This calculator helps you quickly work out the VAT amount on any figure — whether you need to add VAT to a net price for an invoice, or extract the VAT from a gross price shown on a receipt.
To add VAT: multiply the net amount by 1.20. To remove VAT: divide the gross amount by 1.20. For example, £1,000 net becomes £1,200 gross (£200 VAT). Conversely, £1,200 gross contains £200 VAT with a net value of £1,000.
