What the VAT Calculator Does
This VAT calculator separates a price into before VAT, VAT amount, and after VAT totals. It can add VAT to a net price, remove VAT from a VAT-inclusive price, or find the VAT amount from either input type.
How to Add VAT
To add VAT, use Gross price = Net price x (1 + VAT rate / 100). The VAT amount is the net price multiplied by the VAT rate.
How to Remove VAT
To remove VAT, use Net price = Gross price / (1 + VAT rate / 100). Then VAT amount = gross price - net price.
Subtracting the VAT percentage directly from the gross price is incorrect because the VAT percentage is based on the net price, not the gross total.
VAT Examples
Adding VAT: a $100 net product at 20% VAT has $20 VAT and a $120 gross price.
Removing VAT: a $120 invoice total at 20% VAT contains $100 net price and $20 VAT.
Inclusive VAT amount: a $107.50 gross price at 7.5% VAT contains $100 net price and $7.50 VAT.
VAT vs Sales Tax
VAT is generally collected through stages of the supply chain, while sales tax is generally charged at the final sale. Rules vary by country and jurisdiction, so this page does not provide legal or tax advice. For sales-tax-style checkout math, use the Sales Tax Calculator.
Common VAT Mistakes
- Subtracting the VAT percentage directly from a gross price.
- Confusing net price with gross price.
- Using the wrong VAT rate for the product, customer, or transaction.
- Treating comparison rates as official country rates.
- Forgetting exemptions, reduced rates, local rules, or business registration requirements.
- Rounding too early instead of calculating first and rounding final results.

Frequently Asked Questions
Common questions about VAT Calculator and how to read the result.
What is VAT?
VAT means value added tax. It is commonly calculated as a percentage of the net price, producing a VAT amount and gross price.
How do I add VAT to a price?
Multiply the net price by 1 plus the VAT rate as a decimal. For example, $100 at 20% VAT becomes $100 x 1.20 = $120.
How do I remove VAT from a price?
Divide the gross price by 1 plus the VAT rate as a decimal. The VAT amount is gross price minus net price.
Why can't I subtract 20% directly from a VAT-inclusive price?
Because the VAT rate is applied to the net price, not the gross price. A $120 gross price with 20% VAT has a $100 net price and $20 VAT.
What is the difference between net and gross price?
Net price is before VAT. Gross price is after VAT and includes the VAT amount.
Is VAT the same as sales tax?
No. VAT and sales tax are structured differently, and rules vary by country and jurisdiction.
Can VAT rates vary?
Yes. VAT rates, reduced rates, exemptions, and rules vary by country, product, transaction type, and date.
Does this calculator provide tax advice?
No. It is a general VAT math estimate, not tax, accounting, legal, or business advice.
