VAT Calculator United Kingdom

How this UK VAT calculator works

This calculator estimates the gross amount you would charge in the United Kingdom when VAT is added to a net price. Enter the net amount before VAT and the VAT rate as a percentage, and the tool will instantly return the total including VAT. It is useful for invoices, quotes, receipts, and quick pricing checks.

In UK pricing terms, net is the amount before VAT, VAT is the tax added, and gross is the final total including VAT. The formula used here is simple: gross amount = net amount × (1 + VAT rate ÷ 100). For example, a £100 net price at 20% VAT gives a gross total of £120.

Common UK VAT rates include the standard 20% rate, a reduced 5% rate for some qualifying goods and services, and 0% for some zero-rated supplies. Always confirm the correct rate for your product or service before issuing an invoice or relying on the result for compliance.

Important caveat

This calculator provides an estimate based on the figures you enter and does not determine the correct VAT treatment for a specific transaction. VAT rules can vary by product, service, customer type, and place of supply. If you need to remove VAT from a gross amount, account for exemptions, or confirm eligibility for reduced or zero rates, check current HMRC guidance or speak with a qualified accountant or tax adviser.

What does this calculator show?

It calculates the gross total including VAT from a net amount and a VAT rate. In other words, it helps you add VAT to a pre-tax price.

Can I use this for the standard UK VAT rate?

Yes. The default rate is set to 20%, which is the standard VAT rate commonly used in the UK. You can change the rate if your transaction uses a different valid VAT rate.

What is the difference between net and gross?

Net is the amount before VAT. Gross is the amount after VAT has been added. The VAT amount is the difference between the two figures.

How do I remove VAT from a total instead of adding it?

This page is set up to add VAT to a net amount. To remove VAT from a gross total, divide the gross amount by 1 plus the VAT rate expressed as a decimal. For example, divide by 1.20 to remove 20% VAT.

Who typically uses a UK VAT calculator?

Freelancers, retailers, contractors, accountants, small business owners, and online sellers often use VAT calculators to check invoice totals, prepare quotes, and avoid pricing mistakes.
