A Guide to Calculating VAT
Tired of confusing tax math? This free VAT calculator gives you instant, accurate results whether you're adding VAT to an invoice or removing it from a purchase price. Value-Added Tax (VAT) is a consumption tax used in many countries, and calculating it correctly is essential for businesses and consumers alike.
This tool simplifies the two most common VAT calculations, helping you understand the price breakdown in seconds.
How to Use the VAT Calculator: A Simple Guide

- Enter the Price: Input the amount you are starting with. This is the price before tax if you are adding VAT, or the total price including tax if you are removing VAT.
- Enter the VAT Rate: Type in the applicable VAT rate as a percentage (e.g., 20 for 20%).
- Click 'Calculate': Get an instant, clear breakdown of the net (pre-tax), VAT, and gross (total) amounts.
VAT Calculation Formulas Explained
Understanding the math behind the tool can be helpful. Here are the standard formulas:
- To Add VAT: The formula is $Gross Price = Net Price \times (1 + \frac{VAT Rate}{100})$. For a $100 item with 20% VAT, the calculation is $100 \times 1.20 = $120.
- To Remove VAT (Reverse VAT): The formula is $Net Price = \frac{Gross Price}{1 + \frac{VAT Rate}{100}}$. To find the pre-tax price of a $120 item that includes 20% VAT, you calculate $\frac{$120}{1.20} = $100$. The VAT amount is then $120 - $100 = $20$.

Frequently Asked Questions (FAQ)
What is the formula to calculate VAT?
To add VAT to a net price, the formula is: Gross Price = Net Price * (1 + VAT Rate / 100). To remove VAT from a gross price, the formula is: Net Price = Gross Price / (1 + VAT Rate / 100).
How do you calculate VAT backwards?
To calculate VAT backwards (i.e., remove it from a total price), you divide the total (gross) price by (1 + the VAT rate). For example, if a £120 item includes 20% VAT, the calculation is £120 / 1.20 = £100. This gives you the original price before tax.
What is the difference between VAT and Sales Tax?
VAT (Value-Added Tax) is collected at every stage of the supply chain, and businesses can often reclaim the VAT they pay. Sales Tax is only collected at the final point of sale to the consumer. While the end consumer pays both, the collection mechanism is different.
What does 'Net Amount' mean?
The Net Amount is the price of a product or service before any VAT has been added. It is also referred to as the 'VAT exclusive' price.
What does 'Gross Amount' mean?
The Gross Amount is the total price after VAT has been added. It is the final price a consumer pays and is also known as the 'VAT inclusive' price.
