Understanding GST Calculation
Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multistage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes.
GST Exclusive Calculation
Use this when you have the net amount and want to add GST to it.
GST Amount = (Original Cost × GST Rate) / 100
Net Price = Original Cost + GST Amount
Net Price = Original Cost + GST Amount
GST Inclusive Calculation
Use this when you have the total amount and want to find the original cost before tax.
GST Amount = Total Amount - [Total Amount × {100 / (100 + GST Rate)}]
Original Cost = Total Amount - GST Amount
Original Cost = Total Amount - GST Amount
