1. Introduction to VAT
If you’re asking how is VAT calculated, it refers to the process of working out the Value Added Tax applied to goods and services. VAT is a consumption tax charged at each stage of the supply chain, and businesses registered for VAT must collect and pay it to HMRC in the UK.
2. What Is VAT?
- VAT (Value Added Tax) is a tax added to the price of most goods and services.
- In the UK, the standard VAT rate is 20%, but some items are charged at reduced rates (5% or 0%).
3. How Is VAT Calculated – The Formula
To calculate VAT, use the following formulas:
- Adding VAT to a Net Price (Excluding VAT):
VAT = Net Price × VAT Rate
Gross Price = Net Price + VAT - Extracting VAT from a Gross Price (Including VAT):
VAT = Gross Price × (VAT Rate ÷ (100 + VAT Rate))
Net Price = Gross Price – VAT
4. Examples of VAT Calculation
- Adding VAT (20%):
Net Price = £100
VAT = £100 × 20% = £20
Gross Price = £100 + £20 = £120 - Extracting VAT from £120 (20% VAT included):
VAT = £120 × (20 ÷ 120) = £20
Net Price = £120 – £20 = £100
5. Different VAT Rates in the UK
- Standard Rate (20%) – Most goods and services.
- Reduced Rate (5%) – Domestic fuel, children’s car seats.
- Zero Rate (0%) – Most food, books, newspapers, children’s clothes.

6. VAT Registration Threshold
