How to Use This UK VAT Calculator
Enter your amount, choose the applicable VAT rate, then click either Add VAT or Remove VAT. The result shows your gross total, net amount, and VAT portion — everything you need for an invoice or expense claim.
Adding VAT (Net → Gross)
If you're quoting a customer a net price and need the VAT-inclusive figure, enter your net amount and click Add VAT. For example, £500 net at 20% becomes £600 gross, with £100 VAT.
Removing VAT (Gross → Net)
If a price already includes VAT — for example, on a receipt where you want to reclaim VAT — enter the gross amount and click Remove VAT. The tool divides by 1.2 to find the original net price.
Frequently Asked Questions
- What is the current UK VAT rate in 2026?
- The standard rate is 20% for most goods and services. A reduced rate of 5% applies to items like domestic energy. Many essentials including food, books, and children's clothing are zero-rated.
- How do I calculate VAT manually?
- To add 20% VAT, multiply the net price by 1.2. To remove 20% VAT from a gross price, divide by 1.2. For 5% VAT, use 1.05 instead.
- Do I need to be VAT registered to use this?
- No. Anyone can use this calculator — whether you're VAT registered, checking a supplier's invoice, or just want to understand the tax element of a purchase.
- When do I need to register for VAT?
- You must register if your taxable turnover exceeds £90,000 in any rolling 12-month period. You can also register voluntarily below this threshold, which lets you reclaim VAT on business expenses.
- Is this VAT calculator free?
- Yes — completely free to use, with no sign-up, no downloads and no limits. Bookmark it for daily use.
- Can I use the result on a VAT invoice?
- Yes. The figures shown are correct to two decimal places, which is what HMRC requires on a valid VAT invoice. Always round to the nearest penny when displaying VAT amounts.
