VAT Calculator UK: add or remove VAT (20%)
Add VAT to a net price, or take it out of a VAT-inclusive total, at 20%, 5% or any rate you choose.

How it works
To add VAT: gross = net × (1 + rate). At 20%, multiply by 1.2.
To remove VAT: net = gross ÷ (1 + rate). At 20%, divide by 1.2. A common mistake is taking 20% off the total, which gives the wrong answer.
The UK standard rate is 20%, the reduced rate is 5% (e.g. home energy, children's car seats) and some goods are zero-rated. Businesses must register once taxable turnover passes £90,000.
