Understanding GST in India
Before using a GST Calculator, it’s important to understand the basics of GST. GST is a value-added tax levied on most goods and services sold for domestic consumption. It is divided into:
- CGST (Central GST): Collected by the central government.
- SGST (State GST): Collected by the state government.
- IGST (Integrated GST): Collected for interstate transactions and imports.
GST Rates in India
GST rates vary depending on the category of goods or services. The most common slabs are:
- 0% GST: Essential items such as fresh fruits and vegetables.
- 5% GST: Essential goods like packaged food items.
- 12% GST: Items such as computers and processed food.
- 18% GST: Most goods and services, including electronics and dining out.
- 28% GST: Luxury goods like premium cars and high-end electronics.
How a GST Calculator Works
A GST Calculator typically offers two main functionalities:
Adding GST to a Base Price
- Formula :
GSTAmount=(OriginalCost×GSTRate)/100
NetPrice=OriginalCost+GSTAmount
Removing GST from an Inclusive Price
- Formula :
OriginalCost=(InclusivePrice×100)/(100+GSTRate)
GSTAmount=InclusivePrice−OriginalCost
How to Use a GST Calculator

Using an online GST Calculator is very straightforward. On websites like lsbtools.com, you just need to:
- Enter the amount – This could be the base price (excluding GST) or the price including GST.
- Choose GST rate – Select from 5%, 12%, 18%, or 28%.
- Select calculation type – Whether you want to add or remove GST.
- Get results instantly – The calculator will display the GST amount and the final price.
Example Calculations
Example 1: Adding GST
- Base Price: ₹1,000
- GST Rate: 18%
- GST Amount = ₹1,000 × 18% = ₹180
- Net Price = ₹1,000 + ₹180 = ₹1,180
Example 2: Removing GST
- Inclusive Price: ₹1,180
- GST Rate: 18%
- Original Cost = ₹1,180 × 100 / 118 = ₹1,000
- GST Amount = ₹1,180 – ₹1,000 = ₹180
