How do I calculate VAT?
To add VAT, multiply the net price by (1 + rate ÷ 100): 100 plus 20% UK VAT is 100 × 1.2 = 120. To remove VAT from a price that already includes it, divide by (1 + rate ÷ 100): 120 ÷ 1.2 = 100, so the VAT was 20. FixDoks's VAT Calculator does both, with standard rates for many countries.

How to use VAT Calculator
- Choose Add VAT (you have the price before VAT) or Remove VAT (the price already includes it).
- Enter the amount.
- Tap your country's standard rate or type any rate, for example a reduced rate.
- Read the net price, the VAT and the gross price.
How to add VAT
Gross price = Net price × (1 + VAT rate ÷ 100)
Example with the UK standard rate of 20%: a net price of 250 becomes 250 × 1.20 = 300, and the VAT is 50.
How to remove VAT
Net price = Gross price ÷ (1 + VAT rate ÷ 100)
A common mistake is to take 20% off the gross price. That gives the wrong answer: 20% of 300 is 60, but the VAT in 300 is only 50. Always divide by 1.20 instead: 300 ÷ 1.20 = 250. For a 20% rate the VAT is one sixth of the gross price.
Standard VAT rates
The quick buttons use the standard rates checked on official government sources in September 2026: UK 20%, Germany 19%, France 20%, Italy 22%, Spain 21%, Netherlands 21%, Ireland 23%, Belgium 21%, Austria 20%, Poland 23%, Portugal 23%, Sweden 25%, Finland 25.5%, UAE 5%, Saudi Arabia 15%, Switzerland 8.1% and South Africa 15%.
Many countries also have reduced rates for items such as food, books or energy, and some goods are zero-rated or exempt. Type the rate that applies to your item if it is not the standard one. Rates change from time to time, so check your tax authority for anything official.
VAT on invoices
If you are VAT registered, invoices usually show the net amount, the VAT rate, the VAT amount and the total. Use Add VAT to build an invoice from your price, or Remove VAT to find how much of a receipt you can reclaim, if you are allowed to.
