- 0% - Essential goods
- 5% - Common household items
- 12% - Processed foods, computers

- 28% - Luxury items, sin goods
GST Components
GST in India is divided into three components:
- CGST: Central GST levied by Central Government
- SGST: State GST levied by State Government
- IGST: Integrated GST for inter-state transactions
Calculation Formulas
Forward Calculation:
GST Amount = Base Amount × (GST Rate / 100)
Total Amount = Base Amount + GST Amount
Backward Calculation:
Base Amount = Total Amount ÷ (1 + GST Rate / 100)
GST Amount = Total Amount - Base Amount
GST Amount = Base Amount × (GST Rate / 100)
Total Amount = Base Amount + GST Amount
Backward Calculation:
Base Amount = Total Amount ÷ (1 + GST Rate / 100)
GST Amount = Total Amount - Base Amount
