자주 묻는 질문
›How do I add VAT to a net amount?
Multiply the net amount by 1 + VAT rate. For 20% VAT: net × 1.2 = gross. So £100 net = £120 gross.
›How do I extract VAT from a gross amount?
Divide the gross by 1 + VAT rate, then subtract from the gross. For 20%: gross ÷ 1.2 = net, gross − net = VAT.
›Does this work for US sales tax?
Yes — sales tax math is identical to VAT math; just enter your local rate (e.g. 8.875% for NYC).
›What's the standard UK VAT rate?
20% standard rate, 5% reduced (e.g. domestic energy), 0% zero-rated (most food, books, children's clothing).
›Is the calculator free?
