What Is GST?
GST stands for Goods and Services Tax. It is a tax system that has eliminated many indirect taxes such as excise duties and VAT etc. It is comprehensive and is applies to all goods and services. However, alcohol for consumption by people and petroleum products are exempted from this tax.
Under the system of GST, all goods and services are divided into tax slabs. They are put into specific slabs based on their nature. The tax rates range from 0% to 28%. There are three main components of GST- CGST, SGST, and IGST.
CGST and SGST are charged separately by the Central and State governments respectively on the same goods and services. IGST is charged for the movement of goods interstate or between states.
How to Calculate GST?
It is important to know how to calculate GST accurately to avoid any tax penalties and maintain accurate financial reports. Although this can be done easily by using a GST calculator it is important to know the formula as well. The GST calculation formula is as follows:
GST = (Original cost * GST rate)/100
Here, the original cost is the cost of the goods and services before adding GST. The GST rate is the rate of GST that applies to specific goods and services based on where they lie in the tax slab.
For a better understanding of this concept, let us take an example. If the original cost of a product is Rs. 100 and the applicable GST on it is 18%, the GST amount would be=GST = (100*18)/100=18
Therefore, the total cost of the product now after adding GST is Rs. 100 + Rs. 18 = Rs. 118.
Calculating GST Percentage
To know how to calculate the GST percentage, you need to know the GST amount and the original cost of the product or service.
GST percentage = (GST amount/Original cost) * 100
Let us look at an example to understand this concept better.
For example, if the original cost of a product is Rs. 100 and the GST amount is Rs. 18, then the GST percentage would be:
GST percentage = (18/100)*100
= 18%
Therefore, the GST rate applicable here is 18%.
How to Calculate For GST Addition
To calculate the final amount chargeable without using a GST calculator, you can use the following GST formula:
Final price = Original Cost + GST amount
Here, the original cost is the cost of the product or service before adding GST to it. The GST amount is the amount of GST chargeable on a product or service.
Let us understand it better by using an example. To calculate the GST amount, you can use the following formula:
GST = (Original cost * GST rate)/100
If the original cost is Rs. 1000 and the GST rate is 18%, then the GST amount will be: (1000*18)/100
= Rs. 180
Final price = Original cost + GST amount
= Rs. 1000+180
= Rs. 1180.
Therefore, the final price calculated by using the GST formula is Rs. 1180.
How to Calculate For GST Removal
To calculate the price of a product or a service before GST was added to it without using a GST calculator, you can use the following GST formula:
Original Cost = Final price / (1 + GST rate/100)
Here, the final price is the cost of an object or service after GST has been added to it. The GST rate is the GST percentage applicable to goods and services based on what they are and where they lie on the tax slab.
Let us look at an example to understand this concept better.
For example, if the final price is Rs. 1200 and the applicable GST rate is 20%, then the original cost of a product before GST was added to it would be:
Original cost = 1200/(1+20/100)
= Rs. 1000
Therefore, the original cost of the product or service before GST was added to it was Rs. 1000. So, you can see now that it is quite simple to calculate GST using the GST formula. However, these things can also be calculated using a GST calculator.
| Formula | Example | |
| Calculation of GST Amount | GST = (Original Cost * GST rate)/100 | Original cost = Rs.100, GST rate = 18% GST = (100*18)/100 = Rs.18 |
| Calculation of GST Percentage | GST percentage = (GST amount / Original cost)*100 | Original cost = Rs.100, GST rate = Rs.18 GST percentage = (18/100)* 100 = 18% |
| Calculation for GST Addition | Final price = Original Cost + GST amount | Original cost = Rs.1000, GST amount = Rs. 180 Final price = 1000 + 180 = Rs.1180 |
| Calculation for GST Removal | Original Cost = Final price (1 + GST rate/100) | If the final price = Rs.1200, GST rate = 20% Original cost = 1200 / (1 + 20/100) = Rs. 1000 |

Tax components under GST
Under the GST regime, there are three main tax components:
- Central Goods and Services Tax (CGST): Tax levied by the central government on the intra-state supply of goods and services. The revenue collected under CGST goes to the central government.
- State Goods and Service Tax (SGST): It is levied by the state government on the supply of goods and services in the state. The revenue collected under SGST goes to the state government.
- Integrated Goods and Services Tax (IGST): It is levied by the central government on the supply of goods and services. In the case of inter-state transactions, IGST replaces both CGST and SGST. The revenue collected under IGST is shared between the central and state governments.
