What Is VAT?

Value Added Tax (VAT) is a consumption tax applied to goods and services at each stage of production and sale. It is one of the most common taxes worldwide, used in over 160 countries. In the UK it is typically 20%, in most EU countries it ranges from 17% to 27%, and in many other regions it goes by names like GST (Goods and Services Tax) or sales tax.

Understanding how to calculate VAT is essential for both consumers and businesses — whether you're checking if a price is correct, filing a tax return, or building a budget.

Formula 1: Adding VAT to a Price (Exclusive → Inclusive)

This is used when a price is listed without VAT (net price) and you want to find the final price the customer pays.

Price with VAT = Net Price × (1 + VAT Rate / 100)
Example: A product costs $200 before VAT. The VAT rate is 20%. What is the final price?

Step 1: 1 + (20 / 100) = 1.20
Step 2: $200 × 1.20 = $240

The customer pays $240. The $40 difference is the VAT amount.

Formula 2: Removing VAT from a Price (Inclusive → Exclusive)

This is used when a price already includes VAT (gross price) and you want to find the original net price. This is common for businesses that need to record prices before tax.

Net Price = Gross Price ÷ (1 + VAT Rate / 100)
Example: A receipt shows a total of $240 including 20% VAT. What was the original price?

Step 1: 1 + (20 / 100) = 1.20
Step 2: $240 ÷ 1.20 = $200

The original net price was $200, and the VAT paid was $40.

Formula 3: Calculating Just the VAT Amount

Sometimes you only need to know how much VAT is included in a price, without changing the total.

VAT Amount = Gross Price − (Gross Price ÷ (1 + VAT Rate / 100))
Example: A bill totals $360 including 20% VAT. How much of that is tax?

Step 1: $360 ÷ 1.20 = $300 (net price)
Step 2: $360 − $300 = $60 VAT

Tips for Businesses

If you are VAT-registered, you charge VAT on your sales (output tax) and can reclaim the VAT you paid on business purchases (input tax). The difference is what you pay to the government. Always keep receipts and invoices that clearly show the VAT rate and amount separately.

For international sales, VAT rules vary significantly — goods exported outside the EU, for example, are typically zero-rated, meaning you charge 0% but still report the transaction.
