What is GST?

Goods and Services Tax (GST) is an indirect tax introduced in India on 1 July 2017. It replaced several central and state taxes such as VAT, Service Tax, Excise Duty, and Entry Tax, creating a unified taxation system across the country.

GST is applied to most goods and services sold in India. The tax collected is shared between the Central Government and State Governments depending on the type of transaction.

GST Formula

To Add GST

GST Amount = Original Price × GST Rate ÷ 100

Final Price = Original Price + GST Amount

Example

Original Price = ₹1,000

GST Rate = 18%

GST Amount = ₹180

Final Price = ₹1,180


To Remove GST

Original Price = GST Inclusive Price ÷ (1 + GST Rate ÷ 100)

Example:

Inclusive Price = ₹1,180

GST Rate = 18%

Original Price = ₹1,000

GST = ₹180

Example of GST Calculation

Suppose you purchase a laptop costing ₹50,000 and GST is 18%.

GST Amount

₹50,000 × 18%

= ₹9,000

Final Price

₹50,000 + ₹9,000

= ₹59,000
