Detailed GST Calculation Methodology

The Goods and Services Tax (GST) in India follows a multi-tiered structure with rates of 0%, 5%, 12%, 18%, and 28%. The calculation methodology varies based on whether the transaction is intra-state or inter-state:

Intra-State Transactions (Within same state)

For transactions within the same state, both CGST (Central GST) and SGST (State GST) are applied:

• Total GST = CGST + SGST
• CGST = (Original Price × GST Rate) / 2
• SGST = (Original Price × GST Rate) / 2
• Final Price = Original Price + CGST + SGST

Inter-State Transactions (Between different states)

For transactions between different states, IGST (Integrated GST) is applied:

• IGST = Original Price × GST Rate
• Final Price = Original Price + IGST
