What is GST?

GST (Goods and Services Tax) is a consumption-based tax levied on the supply of goods and services. It's a comprehensive, multi-stage tax that has replaced multiple indirect taxes in many countries, simplifying the tax structure and making transactions more transparent.

Our GST Calculator helps you quickly calculate the GST amount and determine the final price, whether you're adding GST to a base price or extracting GST from an inclusive price.

How GST Works

GST is applied at each stage of the supply chain, with credit for tax paid at previous stages. Key aspects include:

Formulas

GST Exclusive:
GST Amount = Original Cost ร— (GST Rate / 100)
Net Price = Original Cost + GST Amount

GST Inclusive:
GST Amount = Original Cost ร— [GST Rate / (100 + GST Rate)]
Net Price = Original Cost - GST Amount

Example Calculations

Example 1: Adding GST (Exclusive)

  • Original Price: $1,000
  • GST Rate: 18%
  • GST Amount: $180
  • Total Price: $1,180

Example 2: Extracting GST (Inclusive)

  • Total Price (GST inclusive): $1,180
  • GST Rate: 18%
  • GST Amount: $180
  • Original Price: $1,000
