This disclaimer was last updated in October 2026.

We built Vat Calculator (vat-calculator.online) to make everyday VAT sums quick and painless. That said, it’s important to be clear about what this site is — and what it isn’t. Please read this disclaimer before relying on anything you find here.

Calculators Are a Guide, Not Advice

Our calculators produce estimates based on the numbers you type in and the standard UK VAT rates. They are general-purpose tools, not professional tax or financial advice. They don’t know anything about your business, your accounting method, or whether a particular product qualifies for a reduced or zero rate. Treat every result as a starting point, not the final answer.

Accuracy of Results

We take care to keep the calculators correct and the content up to date, but VAT rules change, rates vary between goods and services, and mistakes can happen. We make no guarantee that any calculation, article, or figure on this site is accurate, complete, or current. You use the results at your own risk.

Check With HMRC or a Qualified Accountant

Before you make any decision that matters — filing a VAT return, setting prices, issuing invoices, signing a contract, or anything that could affect your tax bill — please verify the figures with HMRC’s official guidance or a qualified accountant. A free online calculator is no substitute for advice tailored to your situation.

No Liability

To the fullest extent permitted by law, we accept no responsibility for any loss or damage that results from using this site or relying on its content. That includes, but isn’t limited to, incorrect calculations, over- or underpaid VAT, tax penalties, interest charges, or business decisions based on our results. If something on this site looks wrong, we’d genuinely like to know — please tell us through our Contact Us page so we can look into it.

External Links

We link to outside websites (such as HMRC) when we think they’ll help. We don’t control those sites and we’re not responsible for their content, accuracy, or privacy practices. Following a link doesn’t mean we endorse everything on that site.
