Calculation Formula
GST Exclusive = Base × Rate / 100 | GST Inclusive Base = Total / (1 + Rate / 100)
Where:
- Base: Pre-tax Supply Value
- Rate: Applicable GST Slab Percentage (5%, 12%, 18%, 28%)
- Total: Gross Inclusive Final Amount
Example Calculation
Adding 18% GST on a base professional consulting service of ₹50,000 (Intra-State)
Base Value: ₹50,000
GST Rate: 18%
Supply Type: Intra-State
Outcome: Total GST: ₹9,000 (CGST ₹4,500 + SGST ₹4,500) | Grand Invoice Total: ₹59,000
Intra-state supply splits 18% tax equally between Central GST (9%) and State GST (9%).
Important Assumptions
- Intra-state transactions split GST equally between CGST (50%) and SGST (50%).
- Inter-state supplies apply full GST under IGST (100%).
