What is GST?

Goods and Services Tax (GST) is an indirect tax imposed in India which is levied on the supply of goods and services. GST is a comprehensive, multi-stage, destination based tax levied on every value addition. GST came into effect on 1st July 2017 and replaced most indirect taxes in the country. Under GST goods and services are divided into five distinct tax rates- 0%, 5%, 12%, 18% and 28%. However, some products such as petroleum products, alcoholic drinks, and electricity are not taxed under GST. These products are taxed separately by the individual state governments, as per the previous tax regime.

What are different tax heads under GST?

GST can be categorised under four heads such as Central Goods and Services Tax (CGST), State Goods and Services Tax (SGST), Union Territory Goods and Services Tax (UTGST) and Integrated Goods and Services Tax (IGST).
IGST is charged for interstate supplies where the place of supply is in different State compared to the location of the supplier. Equal rate of CGST and SGST(approximately half the GST rate applicable for IGST) is charged for intrastate supplies where the place of supply is in the same State compared to the location of the supplier.

Formulae for GST Calculation:

Any business, manufacturer, wholesaler and retailer can calculate GST easily with the help of the following formula:

  • Where GST is excluded:
    GST Amount = (Value of supply x GST%)/100
    Price to be charged = Value of supply + GST Amount
  • Where GST is included in the value of supply:
    GST Amount = Value of supply – [Value of supply x {100/(100+GST%)}]

Examples for understanding GST calculation

Given below is a simple illustration for GST calculation:

Particulars Rate(%) Amount
Invoice value 12% 100,000
GST 12,000
Price to be charged on the Invoice 112,000

Calculation of GST by Manufacturers:

Particulars Rate(%) Amount Pre-GST Amount under GST
Cost of the product 200,000 200,000
Profit 10.00% 20,000 20,000
Excise Duty 12.50% 27,500 Nil
Total 247,500 220,000
VAT 12.50% 30,938 Nil
CGST 6% Nil 13,200
SGST 6% Nil 13,200
Final Invoice to the wholesaler 278,438 246,400

The manufacturer saves Rs.160 on a cost of 1000 points i.e. 16% savings on the cost due to change in tax.

There is a cost reduction for manufacturers, who pass this benefit along the supply chain to the wholesalers, retailers and end-consumers.

Calculation of GST by Wholesalers & Retailers:

Particulars Rate(%) Amount Pre-GST Amount under GST
Cost of the product 278,438 246,400
Profit 10% 27,844 24,640
Total 306,282 271,040
VAT (Rs. 306282 x 12.5%) – (Credit on VAT paid above Rs. 30,938) 12.50% 7,347 Nil
CGST (Rs. 271040 x 6%) – (Credit on CGST paid above Rs.13,200) 6% Nil 3,062
SGST (Rs. 271040 x 6%) – (Credit on SGST paid above Rs.13,200) 6% Nil 3,062
Final Invoice to the end-consumer 313,629 277,164

The cost of the product falls due under the GST regime and the end-consumer has to pay a lesser price for the goods at the same profit margin earned by wholesalers and retailers.
