A **VAT / GST Calculator** is a simple and essential tool for businesses and consumers alike. It performs two very specific functions: it lets you **add tax** to a net price to find the total gross price, or it lets you **remove tax** from a gross price to find the original net price. VAT (Value Added Tax) and GST (Goods and Services Tax) are both common types of **sales tax** used worldwide, and this calculator works for either one.
The math is simple, but it's different depending on whether you are adding or removing the tax. The most common mistake is using the wrong formula when trying to remove tax.
This is used when you have the pre-tax price (Net Price) and want to find the final price (Gross Price).
Gross Price = Net Price × (1 + Tax Rate)
This is used when you have the final price (Gross Price) and want to find the original price (Net Price).
Net Price = Gross Price / (1 + Tax Rate)
In both cases, the "Tax Rate" is the percentage as a decimal (e.g., 20% = 0.20).
You want to sell a product for $1,000 and need to **add** 20% VAT.
Gross Price = $1,000 × (1 + 0.20) = $1,000 × 1.20 = $1,200
Tax Amount = $1,200 - $1,000 = $200
You bought an item for $1,200, which *included* 20% VAT, and you want to **remove** the tax to find the original price.
Net Price = $1,200 / (1 + 0.20) = $1,200 / 1.20 = $1,000
Tax Amount = $1,200 - $1,000 = $200
Note: You do NOT calculate $1,200 * 20% ($240). This is the most common error. The 20% was applied to the *original* $1,000 price, not the final $1,200 price.
This **sales tax calculator** is used daily by millions of people:
VAT and GST rates vary significantly by country and sometimes even by product (e.g., food vs. luxury items). Here are some common standard rates:
Functionally, VAT (Value Added Tax) and GST (Goods and Services Tax) are very similar. They are both types of consumption taxes. The name just depends on the country. For example, the UK and EU use VAT, while Canada, Australia, and India use GST. This **vat calculator** works for both.
To **remove tax** (e.g., 20% VAT) from a final price, you divide the final price by (1 + tax rate). For example, if the final price is $120 and the tax rate is 20% (0.20), you calculate: $120 / 1.20 = $100. The original price was $100 and the tax was $20.
"Tax inclusive" means the price you see already includes the VAT or GST. This is the "Gross Price." To find the original price, you would use the "Remove VAT/GST" function. "Tax exclusive" means the tax will be added at the checkout.
