UK VAT calculator
Add VAT to a net amount or extract VAT from a gross amount. Standard rate 20%, reduced rate 5%, zero-rated 0% — for 2026/27.
How does UK VAT work?
VAT is the consumption tax on most goods and services sold in the UK. The standard rate is 20% (most things), the reduced rate is 5% (domestic energy, child car seats, some renovations), and the zero rate is 0% (most food, children’s clothing, books, public transport). To add VAT to a net price, multiply by 1.20. To extract VAT from a gross price, divide by 1.20. The VAT registration threshold (April 2024 onwards) is £90,000 of taxable turnover in any rolling 12 months — once you cross it you must register within 30 days. The calculator below handles both directions.
