GST Calculation Mechanics
GST is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax that has subsumed almost all the indirect taxes except a few state taxes.
GST Exclusive means the initial value is tax-free. The tax is calculated on top of this initial value and added.
GST Amount = Original Amount × (GST % / 100)
Total Amount = Original Amount + GST Amount
Total Amount = Original Amount + GST Amount
GST Inclusive means the initial value already contains the GST tax amount. The tax is extracted backwards from the total value.
Net Amount = Total Value / (1 + (GST % / 100))
GST Amount = Total Value - Net Amount
GST Amount = Total Value - Net Amount
