How to Calculate GST in India
Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. It is a destination-based, multi-staged tax that is levied on every value addition. Understanding whether your price is GST Inclusive or Exclusive is vital for professional invoicing.
GST Calculation Formula
Exclusive GST: Amount + (Amount × Rate / 100)
Inclusive GST: Amount − [Amount × (100 / (100 + Rate))]
Inclusive GST: Amount − [Amount × (100 / (100 + Rate))]
