How to remove VAT from a price
To remove VAT from a price in the UK, divide the total amount by 1.2. This gives you the original price before VAT was added. The difference between the total and the original price is the VAT amount.
To remove VAT step by step:
- Take the total price including VAT
- Divide by 1.20 (for 20% VAT)
- This gives you the original price before VAT
- Subtract this from the total to find the VAT amount
Example:
£120 ÷ 1.2 = £100 (price excluding VAT)
£120 − £100 = £20 VAT
