What Is GST?

GST (Goods and Services Tax) is an indirect tax applied to the sale of goods and services. It is designed to simplify taxation by replacing multiple taxes with a single unified tax system.

Different countries use different names for similar taxes:

  • GST (Goods and Services Tax) – India, Australia, Singapore, Canada, New Zealand

  • VAT (Value Added Tax) – United Kingdom, Germany, France, Spain, Italy, and most European countries

  • Consumption Tax – Japan

  • Sales Tax – Certain regions and states

  • IVA – Mexico

  • SST – Malaysia

Although the names vary, the purpose remains the same: collecting tax on goods and services consumed by end users.

GST Calculation Formula

GST Exclusive Formula

GST Amount = Amount × GST Rate ÷ 100

Total Amount = Amount + GST Amount

Example:

Amount = ₹1,000

GST Rate = 18%

GST = ₹180

Total = ₹1,180

GST Inclusive Formula

Actual Amount = Total Amount ÷ (1 + GST Rate ÷ 100)

GST Amount = Total Amount − Actual Amount

Example:

Total = ₹1,180

GST Rate = 18%

Actual Amount = ₹1,000

GST Amount = ₹180
