20% is preset; click another rate or type your own.
Copy the net price and VAT
Both amounts are shown, with the total.
How to remove VAT from a price
To remove VAT from a price, divide the gross price by one plus the VAT rate as a decimal: by 1.2 at 20%, by 1.05 at 5%, by 1.21 at 21%. The result is the net price, and the difference is the VAT. Here, enter the gross amount in the calculator above, already set to remove VAT, and you get both figures. For example, £120 becomes £100 plus £20 of VAT.
Why you cannot just subtract 20%
Taking 20% off a gross price leaves too little tax removed, because the VAT was worked out on the smaller net price. Take £120: 20% of £120 is £24, and £120 − £24 = £96, which is not the real net price of £100. The right method is to divide by 1.2: £120 ÷ 1.2 = £100.
Quick methods for common rates
| VAT rate | Divide the gross price by | VAT is this fraction of the gross price |
|---|---|---|
| 20% | 1.2 | 1/6 (16.67%) |
| 5% | 1.05 | 1/21 (4.76%) |
| 21% | 1.21 | 21/121 (17.36%) |
| 19% | 1.19 | 19/119 (15.97%) |
Examples: gross price at 20% VAT
| Price with VAT | Price without VAT | VAT included |
|---|---|---|
| £12.00 | £10.00 | £2.00 |
| £60.00 | £50.00 | £10.00 |
| £120.00 | £100.00 | £20.00 |
| £600.00 | £500.00 | £100.00 |
| £1,200.00 | £1,000.00 | £200.00 |
When it helps
- Invoices and receipts that show only the total.
- Reclaiming input VAT on a purchase, when you need the VAT figure.
- Comparing prices shown with and without VAT.
- Selling to businesses, which usually want the net price.
