GST Formula

To Add GST

GST Amount = Original Price × GST Rate ÷ 100

Total Price = Original Price + GST Amount

To Remove GST

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

GST Amount = GST Inclusive Price − Original Price

Our calculator performs these calculations automatically for accurate results.

Example Calculation

Suppose a product costs $500 and the GST rate is 18%.

  • Original Price: $500
  • GST: $90
  • Total Price: $590

If you already have a GST-inclusive price, the calculator can also determine how much tax was included and what the original price was before GST.
