Understanding how to work out VAT is essential for businesses and consumers alike, whether you’re adding VAT to a price or calculating VAT from a gross amount.

What Is VAT and Why Work It Out?

VAT (Value Added Tax) is a percentage-based tax applied to the value of goods and services. Knowing how to work out VAT is crucial for:

Setting correct prices.
Filing VAT returns.
Ensuring compliance with tax regulations.

How to Work Out VAT

To work out VAT, you need the price of the item and the applicable VAT rate.

Calculate VAT on a Net Price:
- Formula: VAT = Net Price × VAT Rate.
- Example: For a net price of £100 and a VAT rate of 20%,
  VAT = £100 × 0.20 = £20.
- Total Price (Net + VAT) = £100 + £20 = £120.
Work Out VAT from Gross Price:
If the VAT is already included in the gross price, you can calculate the VAT amount as follows:
- Formula: VAT = Gross Price × (VAT Rate ÷ (1 + VAT Rate)).
- Example: For a gross price of £120 and a VAT rate of 20%,
  VAT = £120 × (0.20 ÷ 1.20) = £20.
- Net Price = Gross Price - VAT = £120 - £20 = £100.

Working Out VAT for Different Scenarios

Adding VAT: Use the net price and apply the VAT rate.
Removing VAT: Start with the gross price and extract the VAT using the reverse formula.
