Formula

VAT is added by multiplying the net price by 1 plus the VAT rate. VAT is removed by dividing the gross price by 1 plus the VAT rate.

gross = net × (1 + VAT%/100) net = gross ÷ (1 + VAT%/100) VAT amount = gross - net

Examples

  • Net 100 plus 20% VAT = gross 120.
  • Gross 120 including 20% VAT = net 100 and VAT amount 20.
  • VAT rates and rules vary by country and product category.
