To add UK VAT, multiply the net amount by 1 + (rate ÷ 100). At the standard 20% rate that is × 1.20, so £800 × 1.20 = £960, of which £160 is VAT.
UK VAT rates: 20% standard (most goods and services), 5% reduced (domestic energy, children's car seats), 0% zero-rated (most food, books, children's clothes). Zero-rated still appears on VAT returns; exempt supplies (insurance, finance, education) do not.
How it works.
Formula: net × (1 + rate ÷ 100) = gross.
- Convert the rate: 20 ÷ 100 = 0.20.
- VAT amount: £800 × 0.20 = £160.
- Gross: £800 + £160 = £960 (or £800 × 1.20).
