VAT Calculator UK — FAQs
How do I add 20% VAT?
Multiply the net price by 1.20 — £100 net becomes £120 gross.
How do I remove VAT?
Divide the gross by 1.20, don't multiply by 0.8. £120 gross = £100 net + £20 VAT.
What are the UK VAT rates?
20% standard, 5% reduced (domestic fuel, some renovations), 0% zero-rated (most food, children's clothes, books). Registration threshold is £90,000 taxable turnover.
How do I calculate VAT backwards?
Divide the gross price by 1.20 to strip out 20% VAT. The VAT portion is gross ÷ 6 — £120 gross = £100 net + £20 VAT.
What is 20% of £100?
£20 VAT on a £100 net price gives £120 gross. On £120 gross, the VAT inside it is £20.
When must I register for VAT?
When taxable turnover exceeds £90,000 in any rolling 12-month period, or you expect to pass it in 30 days. Voluntary registration below that can reclaim input VAT.
Does VAT apply to services?
Yes — most services attract 20% VAT, with reduced 5% (e.g. home energy) and zero/exempt categories (most food, books, children's clothing, financial services).
