Worked examples

Example 1: Add 18% VAT to a net price of 100 and the VAT amount is 18, giving a gross price of 118.
Example 2: Remove 18% VAT from a gross price of 118 and the net price is 100, with VAT amount of 18.
Example 3: If a net price is 100 and the gross price is 118, the VAT rate is 18%.

Frequently asked questions

How do I add VAT to a price?

Multiply the net price by the VAT rate divided by 100, then add that VAT amount to the net price.

How do I remove VAT from a VAT-inclusive price?

Divide the gross price by 1 plus the VAT rate as a decimal. The result is the net price before VAT.

Can I use this calculator for invoices and receipts?

Yes. It is useful for invoice preparation, receipt checking, and price comparisons where VAT is included or excluded.

What is the difference between net and gross price?

Net price is before VAT. Gross price is the final price after VAT has been added.
