UK Business Example
Large business purchase or capital investment
Net: £20,000 + VAT: £4,000 = £24,000
On Your Invoice
Show £20,000 as the net amount, £4,000 as VAT (20%), and £24,000 as the total amount due.
Reduced Rate (5%)
If 5% VAT applies: £20,000 + £1,000.00 VAT = £21,000.00 total
The UK standard VAT rate is 20%, set by HMRC. To add 20% VAT to any net amount, multiply by 1.20. This is the official HMRC formula used by all UK VAT-registered businesses.
HMRC Formula — Add VAT
£20,000 × 1.20 = £24,000
Net × (1 + VAT rate) = Gross
VAT amount only
£20,000 × 0.20 = £4,000
Net × VAT rate = VAT amount
If £20,000 is the gross (VAT-inclusive) price, you need to divide by 1.20 to find the net amount. This is called reverse VAT or removing VAT.
£20,000 ÷ 1.20 =
£16,666.67 net
VAT element: £3,333.33
