What is GST?
GST (Goods and Services Tax) is an indirect tax applied to the supply of goods and services across India. Introduced in 2017, GST replaced multiple indirect taxes and simplified the taxation system.
Depending on the product or service, GST may be charged at different rates such as:
| GST Rate | Common Usage |
|---|---|
| 0% | Essential goods |
| 5% | Daily-use products |
| 12% | Processed goods |
| 18% | Most products and services |
| 28% | Luxury and premium products |

GST Exclusive vs GST Inclusive
GST Exclusive
In an exclusive GST calculation, tax is added to the product price.
- Base Price = ₹1,000
- GST Rate = 18%
- GST Amount = ₹180
- Final Price = ₹1,180
This method is commonly used for wholesale transactions and inventory purchases.
GST Inclusive
In an inclusive GST calculation, the GST amount is already included in the final selling price.
- Final Price = ₹1,180
- GST Rate = 18%
- Base Price = ₹1,000
- GST Amount = ₹180
This method is commonly used in retail billing where customers see the final price.
GST Calculation Formula
To Add GST (Exclusive GST)
Final Price = Base Price + GST Amount
To Remove GST (Inclusive GST)
GST Amount = Final Price − Base Price
Example GST Calculations
Example 1: Add GST
| Particulars | Amount |
|---|---|
| Product Price | ₹5,000 |
| GST Rate | 18% |
| GST Amount | ₹900 |
| Final Price | ₹5,900 |
Example 2: Remove GST
| Particulars | Amount |
|---|---|
| Final Price | ₹5,900 |
| GST Rate | 18% |
| Base Price | ₹5,000 |
| GST Amount | ₹900 |
CGST and SGST Calculation
For transactions within the same state, GST is divided equally into:
- CGST (Central GST)
- SGST (State GST)
For example, if GST is 18%, CGST = 9% and SGST = 9%.
On a GST amount of ₹180, CGST = ₹90 and SGST = ₹90. This helps businesses generate accurate GST invoices.
