How do I calculate VAT?

To add VAT: price × (1 + VAT rate). To extract VAT from an inclusive price: VAT amount = price ÷ (1 + VAT rate) × VAT rate. For a 20% VAT on £100, VAT = £20, total = £120.

About This Calculator

Value Added Tax (VAT) is a consumption tax used in over 160 countries — including all EU nations — applied at each stage of production and collection. Unlike US sales tax (added at point of sale), VAT is embedded in the price. This calculator adds VAT to a price or extracts the pre-VAT price from a VAT-inclusive amount.

VAT = amount × quantity × rate; total = amount × quantity + VAT; reverse: pre-VAT = total ÷ (1 + rate)
