How to Calculate Excluding VAT

Understanding how to calculate excluding VAT is essential for businesses, freelancers, and consumers who want transparency in pricing and compliance with tax regulations. Whether you’re invoicing clients, reviewing receipts, or making purchasing decisions, knowing how to separate VAT from a total amount is a valuable skill.

In this guide, we’ll walk you through how to calculate VAT-exclusive prices, provide formulas, and share examples to help you get it right every time.


🧾 What Is VAT?

VAT (Value-Added Tax) is a consumption tax applied to goods and services. In many countries, VAT is added to the final price consumers pay at the point of sale. Common VAT rates vary by country (e.g., 20% in the EU, 15% in South Africa, or 5% in the UAE).

Knowing how to calculate excluding VAT allows you to identify the net price—the price before tax.


📉 How to Calculate Excluding VAT

To determine the price excluding VAT from a VAT-inclusive amount, use this formula:

VAT Exclusive Price = VAT Inclusive Price / (1 + VAT Rate/100)

✅ Example Calculation:

Let’s say you bought an item for €120 including VAT, and the VAT rate is 20%.

Step 1: Convert the VAT rate to decimal:
20% → 20 / 100 = 0.20

Step 2: Apply the formula:
VAT Exclusive Price = €120 / (1 + 0.20)
VAT Exclusive Price = €120 / 1.2 = €100

Result:

  • Net Price (excluding VAT): €100
  • VAT Amount: €20 (120 – 100)

This method gives you the original price before tax was added.

📌 Related: How to Add VAT

To calculate VAT inclusive pricing (i.e., adding VAT to a base price), simply multiply the net price by the VAT rate and add the result:

VAT Amount = Net Price × VAT Rate
Total Price = Net Price + VAT Amount

Example:

If an item costs €100 (excluding VAT) and the VAT rate is 20%:

  • VAT Amount = €100 × 0.20 = €20
  • Total Price = €100 + €20 = €120
