How to Calculate GST in India

What is GST?

Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. It replaced multiple cascading taxes and unified the Indian market under one tax regime from July 1, 2017.

GST Calculation Formula

To Add GST: Total = Base Amount × (1 + GST Rate/100)
To Remove GST: Base Amount = Total ÷ (1 + GST Rate/100)

CGST, SGST, and IGST Explained

  • CGST (Central GST): Collected by Central Government for intra-state sales
  • SGST (State GST): Collected by State Government for intra-state sales
  • IGST (Integrated GST): Collected by Central Government for inter-state sales
