Calculate VAT — Add or Remove VAT
VAT Formula — How to Calculate VAT
Understanding the VAT calculation formula helps you verify results and calculate VAT manually when needed. There are two core formulas — one to add VAT and one to remove VAT.
Formula to Add VAT
VAT Amount = Net Price × (VAT Rate / 100)
Gross Price = Net Price + VAT Amount
Example — Adding VAT at 23%
Net Price: €100.00
VAT Rate: 23%
VAT Amount: €100 × 23 / 100 = €23.00
Gross Price (incl. VAT): €123.00
Formula to Remove VAT (Reverse VAT)
Net Price = Gross Price ÷ (1 + VAT Rate / 100)
VAT Amount = Gross Price − Net Price
Example — Removing VAT at 23%
Gross Price: €123.00
VAT Rate: 23%
Net Price (excl. VAT): €123 ÷ 1.23 = €100.00
VAT Amount: €123 − €100 = €23.00
Example — Adding VAT at 13.5%
Net Price: €200.00
VAT Rate: 13.5%
VAT Amount: €200 × 13.5 / 100 = €27.00
Gross Price (incl. VAT): €227.00
