Why this matters
If you are VAT-registered (or approaching the £90,000 threshold), getting VAT calculations right on every invoice is not optional. HMRC expects accurate records for your quarterly MTD submissions. This calculator saves time and reduces the risk of errors that could trigger penalties.
Frequently asked questions
What is the current standard VAT rate in the UK?
The current standard VAT rate in the UK is 20%. This applies to most goods and services. Some items qualify for the reduced rate of 5% (such as domestic energy and children's car seats) or 0% (such as food and children's clothing).
How do I add VAT to a price?
To add 20% VAT to a net price, multiply the price by 1.20. For the reduced 5% rate, multiply by 1.05. For example, a net price of £100 becomes £120 at standard rate. This calculator does the maths for you automatically.
How do I remove (reverse) VAT from a gross price?
To remove 20% VAT from a gross price, divide by 1.20. For 5%, divide by 1.05. For example, £120 gross ÷ 1.20 = £100 net. Use the "Remove VAT" option in this calculator to do this instantly.
When do I need to register for VAT?
You must register for VAT when your taxable turnover exceeds £90,000 in any 12-month rolling period (the current threshold as of 2024/25). You can also register voluntarily below this threshold if it benefits your business.
