How this VAT calculator works
Enter an amount and pick a rate. To find the price including VAT, choose Add VAT — the tool multiplies your net figure by the rate and adds it on. To work backwards from a VAT-inclusive price to the amount excluding VAT, choose Remove VAT — it divides the gross by 1 plus the rate. Every figure is rounded to the nearest penny, and the result updates as you type. Nothing is sent anywhere: the maths runs entirely in your browser.
The formulas in plain English
- Adding VAT: VAT = net × rate, then gross = net + VAT. Example: £100.00 + 20% = £120.00 (£20.00 of VAT).
- Removing VAT: net = gross ÷ (1 + rate), then VAT = gross − net. Example: £120.00 at 20% contains £20.00 of VAT, leaving £100.00 net.
UK VAT rates (2026/27)
- Standard rate — 20%: most goods and services.
- Reduced rate — 5%: some supplies such as domestic energy, children's car seats and certain home-energy improvements.
- Zero rate — 0%: zero-rated goods like most food, books and children's clothing. You still record the sale, but no VAT is added.
When do I have to register for VAT?
You must register for UK VAT once your VAT-taxable turnover goes over £90,000.00 in any rolling 12-month period (or if you expect to cross it in the next 30 days). Below that, registration is voluntary — which can still make sense if you mostly sell to other VAT-registered businesses.
