How Indian GST is Calculated

Under the Central Goods and Services Tax (CGST) Act, 2017 and Integrated Goods and Services Tax (IGST) Act, 2017, the Goods and Services Tax in India is destination-based and applied across standard slabs: 0%, 5%, 12%, 18%, and 28%.

1. GST Exclusive Formula

GST Amount = (Base Price × GST Rate) / 100

Total Price = Base Price + GST Amount

2. GST Inclusive Formula

GST Amount = Total Amount - [Total Amount / (1 + (GST Rate / 100))]

Base Price = Total Amount - GST Amount

Intra-State vs Inter-State Tax Rules:

  • Intra-State Supply: If the supplier and recipient are in the same state, the GST amount is divided equally into 50% CGST (Central Government) and 50% SGST (State Government).
  • Inter-State Supply: If goods or services are supplied across state borders, 100% of the tax is levied as IGST (Integrated GST).
