▦ How this calculator works
To add VAT, the amount is multiplied by (1 + rate). To extract VAT already included in a total, the total is divided by (1 + rate) to find the VAT-exclusive amount, and the difference is the VAT component.
◇ Assumptions and what's not included
Some supplies are exempt from VAT entirely (rather than zero-rated), which affects whether a business can reclaim input VAT — this calculator doesn't distinguish exempt from zero-rated supplies.
▤ What to do next
Check the correct VAT rate for your specific goods or service on HMRC's VAT rate guidance before applying it to an invoice.

Frequently asked questions
What's the difference between zero-rated and exempt?+
Zero-rated goods are taxable at 0%, so a VAT-registered business can still reclaim related input VAT; exempt supplies aren't taxable at all and input VAT generally can't be reclaimed against them.
Do I need to be VAT registered to charge VAT?+
Yes, only businesses registered for VAT (mandatory once taxable turnover exceeds the registration threshold) can charge VAT on their invoices.
How do I remove VAT from a total price?+
Divide the total by 1 plus the VAT rate as a decimal (for example, divide by 1.2 for 20% VAT) to get the VAT-exclusive amount.
Is VAT the same across the whole UK?+
Yes, VAT rates are set at a UK-wide level (not devolved), unlike Income Tax which differs in Scotland.
