Understanding GST (Goods and Services Tax)
GST is a destination-based tax on consumption of goods and services. It is levied at all stages right from manufacture up to final consumption with credit of taxes paid at previous stages available as set-off.
One Nation, One Tax
GST has unified the Indian market by replacing a cascade of indirect taxes, making compliance easier and reducing the overall tax burden on goods.
Input Tax Credit
Businesses can claim credit for the tax paid on inputs used in the business, which prevents the cascading effect of taxes (tax on tax).
GST Calculation Formula
Adding GST (Exclusive)
GST Amount = (Original Cost × GST Rate) / 100
Net Price = Original Cost + GST Amount
Example: Product Cost = ₹1,000, GST = 18%
GST = (1000 × 18) / 100 = ₹180
Total Price = ₹1,180
Removing GST (Inclusive)
GST Amount = Original Cost - [Original Cost × (100 / (100 + GST Rate))]
Net Price = Original Cost - GST Amount
Example: Total Price = ₹1,180, GST = 18%
GST = 1180 - [1180 × (100/118)] = 1180 - 1000 = ₹180
Original Cost = ₹1,000
