How do you calculate GST?

To create a GST (Goods and Services Tax) calculator, I can help you with a simple formula or code snippet. The calculation depends on whether you want to:

  1. Add GST to a base amount (to find the total Cost, including GST).
  2. Remove GST from the total amount (to find fiCosthe base cost before GST was added).

The formula to add GST to a base amount is: Total Cost=Base Price+(Base Price×GST Rate100)

The formula to remove GST from a total amount is: Base Price=Total Cost1+(GST Rate100)


  • Total Cost is the final amount after including GST.
  • The base price is iCoste's original Cost before GST.
  • GST Rate is the percentage rate of GST apCostd.
