VAT calculator
Add VAT to a price, or find the VAT hidden inside a total. Enter one number, get the net, the VAT and the gross laid out clearly — at 20%, 5%, or whatever rate you need. Handy at quoting time and again when you fill in your return. Nothing you type is saved or sent anywhere.

Common questions
- How do I add VAT to a price?
- Multiply the net price by 1 plus the VAT rate. At the UK standard rate of 20%, a £1,000 net price becomes £1,200 gross: £1,000 × 1.2. The £200 is the VAT you collect and pass on to HMRC. Switch this calculator to 'Add VAT' to do it for any figure.
- How do I work out the VAT included in a total?
- You can't just take 20% off the gross — that gives the wrong answer. To find the VAT inside a 20% gross figure, divide the total by 6 (or by 1.2 to get the net, then subtract). On a £1,200 gross total the VAT is £200 and the net is £1,000. The 'Remove VAT' mode does this for you at any rate.
- What is the UK VAT rate?
- The standard rate is 20% and applies to most goods and services. A reduced rate of 5% covers things like domestic energy and some home-energy-saving work, and some supplies are zero-rated. Ireland's standard rate is 23%. This calculator has presets for each, and you can type any rate.
- Do I have to charge VAT as a sole trader?
- Only once your taxable turnover passes the VAT registration threshold, or if you register voluntarily. Below it you don't add VAT at all. If you are registered, you must show VAT on your invoices — SoloDesks adds it to every invoice automatically.
