How do I Calculate GST?

What is GST?

Goods and Services Tax (GST) is an indirect tax on the supply of goods and services in India, effective from July 1, 2017. It replaced multiple indirect taxes like Central Excise Duty, VAT, and Octroi. GST is a comprehensive, multi-stage, destination-based tax, with goods and services categorized into five tax rates: 0%, 5%, 12%, 18%, and 28%.

For intra-state sales, Central GST (CGST) and State GST (SGST) are applied, while Integrated GST (IGST) is charged for inter-state transactions. Certain products like petroleum, alcoholic drinks, and electricity are taxed separately by states. Businesses must obtain a GST Identification Number to comply with GST regulations.

Different Forms of GST

GST is categorized into four types, each collected by different government entities:

  • State GST (SGST): Collected by the State Government for intra-state transactions.
  • Central GST (CGST): Collected by the Central Government for intra-state transactions.
  • Integrated GST (IGST): Collected by the Central Government for inter-state transactions and imports.
  • Union Territory GST (UTGST): Collected by the Union Territory Government for intra-UT transactions.

What is a GST Calculator?

A GST calculator is a handy online tool used to compute the GST payable for a month or quarter. It is useful for buyers, manufacturers, wholesalers, and other business users. The calculator helps determine the gross or net price of a product based on the GST amount and provides a breakdown of the percentage-based GST rates. It can also divide the rate between Central GST (CGST) and State GST (SGST) for intra-state transactions or calculate the correct Integrated GST (IGST) for inter-state transactions.

How is GST Calculated?

GST is calculated by applying the relevant GST rate to the net price of goods or services. The GST rates are 5%, 12%, 18%, and 28%.

For Buyers:

  • Input the net price of the item.
  • Enter the applicable GST percentage.

For Manufacturers and Wholesalers/Retailers:

  • Input the cost of production.
  • Enter the profit ratio percentage.
  • Enter the applicable GST percentage.

GST Calculation Formula

To calculate GST, you can use the following formulas based on whether you are adding or removing GST from the base amount:

Adding GST:

  • GST Amount = (Original Cost x GST%)/100
  • Net Price = Original Cost + GST Amount

Removing GST:

  • GST Amount = Original Cost – [Original Cost x {100/(100+GST%)}]
  • Net Price = Original Cost – GST Amount

Steps for GST Calculation

  • Check GST Rate: Determine the applicable GST rate for the goods or services.
  • Determine Transaction Value: Identify the transaction value of the goods or services.
  • Calculate GST Amount: Multiply the transaction value by the GST rate.
  • Calculate Gross Amount: Add the GST amount to the transaction value to get the gross amount payable.

Example of GST Calculation

In case a product Value is Rs.₹1,000 and the GST rate applicable to it is 18%

Then, the net price of the product will be Rs.5,000 + 12% of Rs.5,000 = Rs.5,000 + Rs.600 = Rs.5,600.

Adding GST:

  • GST Amount = (1,000×18) /100 = ₹180
  • Net Price = 1,000+180=₹1,1801,000 + 180 = ₹1,1801,000+180 = ₹1,180

Removing GST:

  • GST Amount = 1,180−{(1,180×100)/118} = ₹180
  • Original Cost =  1,180−180=₹1,0001,180 – 180 = ₹1,0001,180−180 = ₹1,000
