UK VAT rates: 20% standard, 5% reduced (e.g. home energy, children's car seats), 0% zero-rated (e.g. most food, books, children's clothes). Which rate applies depends on what you're selling, not the price, check HMRC guidance if you're unsure. Not tax advice.

How do you calculate VAT on a price?

To add UK VAT, multiply the net price by the rate and add it on: 20% of £100 is £20, so the gross price is £120. To remove VAT from a gross price, divide by 1.2 rather than subtracting 20%, because £120 divided by 1.2 gives back £100 net and £20 VAT.

How do you work out VAT backwards from a total?

To work VAT backwards from a VAT-inclusive total, divide the total by 1 plus the rate as a decimal: by 1.2 at 20% or by 1.05 at 5%. A £240 gross price at 20% divides by 1.2 to £200 net, leaving £40 VAT. Taking 20% off £240 would wrongly give £192.
