To add UK VAT, multiply the net amount by 1 + (rate ÷ 100). At the standard 20% rate that is × 1.20, so £500 × 1.20 = £600, of which £100 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.

  1. Convert the rate: 20 ÷ 100 = 0.20.
  2. VAT amount: £500 × 0.20 = £100.
  3. Gross: £500 + £100 = £600 (or £500 × 1.20).
