GST Calculator – Guide (How to Calculate GST Online in India)


Indirectly, the provision of goods and services in India is taxed at a rate known as the Goods and Services Tax (GST). The Goods and Services Tax (GST) applies to all forms of value creation. It is calculated based on where the final product will be used.

On July 1, 2017, GST was implemented in place of most indirect taxes. For GST, there are five different tax brackets for goods and services: 0%, 5%, 12%, 18%, and 28%.

However, GST does not apply to a few categories of goods and services. These goods continue to be taxed independently by each state’s government.

Read on to learn more about the concept and calculating GST online.

Different Tax Heads Under GST

The Goods and Services Tax (GST) structure can be broken down into four distinct taxation types: 

  • GST at Central Level (CGST), 
  • GST at State Level (SGST), 
  • GST at Union Territory  (UTGST), and 
  • Integrated GST 

When the location of the supplier and the location of the recipient are in different states, the IGST is due on the supply.

When the location of the supplier and the location of the recipient are both in the same state, intrastate supplies are subject to a combined rate of 5% (half the GST rate applicable for IGST).

GST method 

With the unified system of taxation, it is now possible for taxpayers to know the tax levied at different points for various taxable items under the GST regime. For calculating GST, the taxpayer should know the GST rate applicable to various categories. 

The GST process can be explained by a simple illustration :

If the selling price of taxable items is Rs. 2,000 and the GST rate applicable is 18%,

 then the net price calculated will be 

= 2,000+ (2,000X(18/100))

= 2,000+180 

= Rs. 2,180.

Method to calculate GST

To calculate GST, the below-given method is used :

Base amount Inclusive of GST,


(Original Cost * GST% ) / 100 will give the GST Amount 

Next, adding the GST Amount to the original cost will give the Net amount.

Base amount exclusive of GST

Remove GST

Original Cost – (Original Cost * (100 / (100 + GST% ) ) ) will give the GST to be applied

Next, Subtracting GST from the Original cost will give the Net amount
