The VAT maths

  • Adding VAT: £400 × 1.2 = £480.00.
  • Removing VAT: £400 ÷ 1.2 = £333.33. The VAT inside a VAT-inclusive price is one sixth of it, £66.67, not 20%.
  • Taking 20% off £400 would give £320.00, which is £13.33 too low.
  • VAT-registered businesses can usually reclaim the VAT they pay on business costs, so the net figure is their real cost.
