How VAT is calculated
The maths is the same everywhere. Only the rate changes. If you are new to the tax, start with what VAT is.
Adding VAT to a net price
Multiply the net price by one plus the rate. At 20% that is net × 1.2, which gives the gross price.
Removing VAT from a gross price
Divide the gross price by one plus the rate. The difference between the two is the VAT. See the full guide to removing VAT.
Inclusive and exclusive prices
A net price is before VAT and a gross price is after it. Our guide to net vs gross prices shows how to move between them.
net × 1.2 = gross
£1,000 net + £200 VAT = £1,200 gross
gross ÷ 1.2 = net
£1,200 gross ÷ 1.2 = £1,000 net
Common mistake: taking 20% off £1,200 gives £960, not £1,000. Always divide.

VAT calculator FAQs
How is VAT calculated?
To add VAT, multiply the net price by one plus the rate. At 20% that is net × 1.2. To remove VAT, divide the gross price by 1.2. Do not subtract 20%, because the VAT is a share of the net price, not of the total.
Which VAT rates does the calculator use?
The standard rates: 20% for the UK, 5% for the UAE and 15% for Saudi Arabia. Choose Custom to enter any other rate, such as the UK reduced rate of 5% or a zero rate.
Can I work out the original price from a VAT-inclusive total?
Yes. Switch to Remove VAT, enter the total including VAT and the calculator shows the net price and the VAT that was included.
Can I calculate VAT for several items at once?
Yes. The bulk calculator takes a quantity and unit price for each line and totals the net, VAT and gross for all of them.
