VAT Formulas

Quick answer: VAT is calculated by multiplying a base amount by the VAT rate.

  • Add VAT: Gross = Net × (1 + VAT Rate)
  • VAT amount from net: VAT = Net × VAT Rate
  • Remove VAT: Net = Gross ÷ (1 + VAT Rate)
  • VAT removed from gross: VAT = Gross − Net

Use VAT rate as a percentage, then convert it to decimal in the calculation. Example: 20% = 0.20.

FAQ

What is VAT?

VAT stands for Value Added Tax. It is a consumption tax added to goods and services in many countries.

What is the difference between net and gross?
