How to calculate VAT in the UK
To calculate UK VAT at the standard 20% rate, enter the price without VAT in the calculator above: VAT is 20% of that amount and the total is 1.2 times the price. For example, £100 plus VAT is £120, of which £20 is VAT. To take VAT out of a price that includes it, choose remove VAT and enter the gross price; the tool divides it by 1.2.
UK VAT rates
| Rate | Percentage | Typical goods and services |
|---|---|---|
| Standard | 20% | Most goods and services |
| Reduced | 5% | Domestic fuel and power, children's car seats and some energy-saving installations |
| Zero | 0% | Most food, books and newspapers, children's clothes and public transport fares |
Formulas at the 20% rate
- Price with VAT = price without VAT × 1.2
- VAT = price without VAT × 0.2
- Price without VAT = price with VAT ÷ 1.2
- VAT in a gross price = gross price ÷ 6 (the VAT fraction is 1/6)
Examples: adding 20% VAT
| Price without VAT | VAT | Price with VAT |
|---|---|---|
| £10.00 | £2.00 | £12.00 |
| £50.00 | £10.00 | £60.00 |
| £100.00 | £20.00 | £120.00 |
| £250.00 | £50.00 | £300.00 |
| £500.00 | £100.00 | £600.00 |
| £1,000.00 | £200.00 | £1,200.00 |
When you have to charge VAT
A UK business must register for VAT when its taxable turnover goes over £90,000 in any 12-month period, and may register voluntarily below that. Once registered, you charge VAT on standard-rated and reduced-rated sales and can normally reclaim the VAT you pay on business purchases. Zero-rated sales still count towards turnover and must be reported, while exempt supplies work differently.
Checking your numbers
- Round VAT to the nearest penny per invoice rather than per line if your invoice shows a single total.
- Zero-rated is not the same as exempt: zero-rated sales are taxable at 0% and let you reclaim input VAT.
- Rates and thresholds change; confirm the current ones on GOV.UK before filing.
Private by design
The calculation runs in your browser as you type. The amounts you enter are never sent to a server, so you can use real prices, invoices and quotes.
Frequently asked questions
How do I add 20% VAT to a price?
Multiply by 1.2. For example, £50 × 1.2 = £60, and the VAT is £10.

£90,000 of taxable turnover in a 12-month period at the time of writing. Check GOV.UK for the current figure.
