Enter values above to calculate.

To add UK VAT, multiply the net amount by 1 + (rate ÷ 100). At the standard 20% rate that is × 1.20, so £25 × 1.20 = £30, of which £5 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: £25 × 0.20 = £5.
  3. Gross: £25 + £5 = £30 (or £25 × 1.20).
