Add VAT Calculator

Need to add VAT to a price? Enter the net amount and choose a VAT rate. This calculator shows the exact VAT amount and the final gross price — useful for invoicing, quoting, and pricing.

Formula

VAT Amount = Net Amount × (VAT Rate ÷ 100)
Gross Amount = Net Amount + VAT Amount

Take the net amount (before tax) and multiply it by the VAT rate as a decimal. Add the result to the original net amount to get the final price including VAT.

Frequently Asked Questions

When should I add VAT to a price?▾

If you are a VAT-registered business selling goods or services, you must add VAT to your net price before invoicing the customer. The VAT amount must be shown separately on the invoice.

Can I add different VAT rates?▾

Yes. Different products and services may have different VAT rates. In the UK, the standard rate is 20%, but a reduced 5% rate applies to some items, and zero-rated goods carry 0% VAT.

What if my price already includes VAT?▾

If the price already includes VAT, you need to remove (extract) VAT instead. Use the Remove VAT calculator or the main VAT Calculator in remove mode.
