GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes like VAT, service tax, etc.
GST is charged at 5%, 12%, 18%, and 28% depending on the type of goods or services. Some items are exempt from GST.
If amount is exclusive of GST: GST = Amount × (GST Rate / 100), Total = Amount + GST. If amount is inclusive: GST = Amount × (GST Rate / (100 + GST Rate)), Net Amount = Amount - GST.
