Calculate UK Value Added Tax (VAT) at 20%, 5% or 0%
Enter a net or gross amount, pick a UK VAT rate (or Custom…), and choose Add VAT (net to gross) or Extract (gross to net). Results update immediately. Standard rate is 20%; reduced (e.g. domestic fuel, children’s car seats) is 5%; zero-rated supplies (e.g. most food, children’s clothes, books) use 0%.
Example: a London consultant quotes £2,000 net. At 20% the client pays £2,400. Helper for current HM Revenue & Customs (HMRC) rates, not tax advice. Exempt supplies differ from zero-rated and are not a separate rate here. Near the registration line, check the UK VAT registration threshold (£90,000 taxable turnover).
UK VAT calculator: FAQ
What are the current UK VAT rates for goods and services?
Standard 20% on most goods and services, reduced 5% on specific categories such as domestic fuel and children’s car seats, and zero-rated 0% on others (still taxable at 0%, so input Value Added Tax (VAT) can often be reclaimed). Exempt supplies sit outside this calculator and can restrict recovery.
When should I add UK VAT versus extract it from a gross total?
Add Value Added Tax (VAT) when your price is net and you need the customer total for a quote or invoice. Extract when you only have a gross amount; a till receipt, marketplace payout or inclusive price list; and need the net base plus the VAT share for your books.
Is zero-rated UK VAT the same as an exempt supply?
No. Zero-rated is a taxable supply at 0%, so you may usually reclaim related input Value Added Tax (VAT). Exempt supplies are not taxable in the same way and can restrict input VAT recovery. Ask your accountant if a line sits on the border between the two.
How does UK VAT registration relate to using this calculator?
Once you must register for Value Added Tax (VAT), generally above £90,000 taxable turnover in a rolling 12 months, you charge VAT at the correct rate on taxable supplies. Check the UK VAT registration threshold first; if you are still unregistered, do not add 20% on invoices unless you have opted in voluntarily.
