Frequently Asked Questions

Multiply the net price by 1.20. For example, £100 net becomes £120 gross including 20% VAT. The VAT amount is £20.
Divide the gross (VAT-inclusive) price by 1.20 for 20% VAT. Example: £120 ÷ 1.20 = £100 net. Use the "Remove VAT" tab above.
The standard UK VAT rate is 20%. A reduced rate of 5% applies to some goods including domestic energy and children's car seats. Some items are zero-rated (0%).

How UK VAT Works

Value Added Tax (VAT) is a consumption tax added to most goods and services sold in the UK. The standard rate is 20%, but some items attract a reduced rate of 5% and others are zero-rated (0%).

Adding VAT

To add 20% VAT: multiply the net price by 1.20. For example, a product costs £100 net: £100 × 1.20 = £120 including VAT. The VAT portion is £20.

Removing VAT

To remove 20% VAT from a gross price: divide by 1.20. For example, an invoice shows £360 including VAT: £360 ÷ 1.20 = £300 net. The VAT portion is £60. A common mistake is to calculate 20% of £360 (which gives £72) — this is wrong because 20% was added to the net figure, not the gross.

UK VAT Rates

Standard rate (20%): Most goods and services including electronics, clothing, restaurant meals, professional services, and general retail.

Reduced rate (5%): Domestic energy (gas and electricity), children's car seats, and some home renovation work.

Zero rate (0%): Most food and drink, children's clothing, books, newspapers, and public transport.

Exempt: Insurance, education, health services, and financial services. These aren't zero-rated — the distinction is that zero-rated businesses can still reclaim VAT on their costs, while exempt businesses cannot.
