Food, children's clothing
How to Calculate VAT
Adding VAT (Net to Gross)
To add VAT to a price, multiply by 1 + (VAT rate / 100):
Example: A net price of £100 with 20% VAT:
£100 × 1.20 = £120 (including £20 VAT)
Removing VAT (Gross to Net)
To find the net amount from a VAT-inclusive price, divide by 1 + (VAT rate / 100):
Example: A gross price of £120 with 20% VAT:
£120 ÷ 1.20 = £100 (net), with £20 VAT
VAT Registration Threshold
As of 2026, you must register for VAT if your VAT taxable turnover exceeds £90,000 in any rolling 12-month period. You can also register voluntarily below this threshold.
