VAT Calculator

This VAT calculator works in two directions depending on what you know:

• Add VAT tab: Enter the net price (before tax) and the VAT rate. The calculator shows the VAT amount and the final price including VAT. Use this when quoting prices to consumers or calculating what you will charge.
• Remove VAT tab: Enter the gross price (including tax) and the VAT rate. The calculator extracts the original net price and the tax component. Use this when you see a total price and need to find the pre-tax amount for accounting or expense claims.

Click the rate buttons (5%, 10%, 15%, 20%, 21%, 25%) to quickly set common rates, or type any rate into the input field.

Adding VAT to a net price:

VAT Amount = Net Price × (VAT Rate / 100) Gross Price = Net Price + VAT Amount = Net Price × (1 + VAT Rate / 100)

Example: $100 net price at 20% VAT. VAT = $20. Gross price = $120.

Removing VAT from a gross price:

Net Price = Gross Price / (1 + VAT Rate / 100) VAT Amount = Gross Price - Net Price

Example: $120 gross price at 20% VAT. Net price = $120 / 1.20 = $100. VAT amount = $20.

Common mistake: To remove 20% VAT, do not multiply by 80% (0.80). That gives the wrong answer. You must divide by 1.20. Multiplying $120 by 0.80 gives $96, which is wrong. Dividing by 1.20 gives $100, which is correct.
