VAT calculator

Can anyone tell me. how do you calculate VAT UK?

In the UK these are the current vat percentages

So first you need to work out what 20% (20% as a example) of the original price is. Then add it or minus it from the current price to calculate the result.There are only percentage calculators if you prefer that

I will also say that VAT is included in pretty much all prices in the UK (only when it specifies its not … Is it not) so if your coming here on holiday and were just curious what percentage to add when buying … Say a bottle of water. No need to (never understood why shops abroad dont include VAT for supermarket goods)
