GST Formula Used by This Tool
The GST Calculator uses standard GST calculation formulas.
GST Exclusive Formula
GST Amount = Amount × (GST Rate ÷ 100)
Total Amount = Amount + GST Amount
GST Inclusive Formula
GST Amount = Total Amount × GST Rate ÷ (100 + GST Rate)
Base Amount = Total Amount − GST Amount
Example (Exclusive):
Amount = $1,000
GST Rate = 18%
GST = 1,000 × (18 ÷ 100) = $180
Total Amount = $1,180
GST is a form of value-added tax used globally.
