🧾 What is VAT?
VAT - Value Added Tax - is a broad-based consumption tax applied to almost all goods and services sold for use within a jurisdiction. It was first introduced in France in 1954 and has since been adopted by over 170 countries worldwide. The European Union mandates VAT across all member states, while the United Kingdom maintained its own VAT system (set at 20% for most goods) after leaving the EU.
The defining characteristic of VAT is its multi-stage collection mechanism. Every business in the supply chain charges VAT on their sales (output VAT) and can reclaim VAT paid on their purchases (input VAT). This input-output netting means each business only remits the VAT on the value they added - hence "value added" tax. The cumulative effect ensures the full VAT burden falls on the final consumer.
VAT is typically quoted as a percentage of the net (ex-VAT) price. Most countries use a standard rate for most goods, with reduced rates for essential items (food, medicine, children's products) and zero rates for exports. UK rates: standard 20%, reduced 5%, zero 0%. EU standard rates range from 17% (Luxembourg) to 27% (Hungary). Australia and New Zealand use the term GST (Goods and Services Tax) for their equivalent tax at 10% and 15% respectively.
For businesses and consumers alike, understanding how to add VAT to a price and how to reverse-calculate the net price from a VAT-inclusive total is an essential daily skill. This calculator handles both directions instantly for any VAT rate worldwide.
📐 VAT Formula
The mathematics of VAT is straightforward once you understand the two directions:
To add 20% VAT to £100: Gross = £100 × 1.20 = £120. VAT amount = £20.
To remove 20% VAT from £120 (VAT-inclusive): Net = £120 ÷ 1.20 = £100. VAT amount = £20. Note: you must divide by 1.20, not subtract 20% directly - subtracting 20% from £120 gives £96, which is incorrect.
