UK VAT Calculator
Formula
Add VAT: Gross = Net × 1.20 Remove VAT: Net = Gross ÷ 1.20
For any VAT rate: multiply Net by (1 + rate/100) to get Gross. Divide Gross by (1 + rate/100) to extract Net. At 20%: Net × 1.20 = Gross; Gross ÷ 1.20 = Net.
Worked Example
Adding VAT:
A contractor quotes £750 net. Client wants to know the VAT-inclusive total.
Removing VAT:
A receipt shows £120 including 20% VAT. How much is the net amount?
Common Mistakes
- Subtracting 20% to remove VAT. £120 − 20% = £96, not £100. The correct method is £120 ÷ 1.20 = £100.
- Adding VAT twice. If a price is already VAT-inclusive, do not add VAT again. Use "Remove VAT" to verify first.
- Applying the wrong rate. Some goods qualify for the 5% reduced rate (domestic fuel, children's car seats) or 0% (most food, books).
