GST Calculation Formulas
Variables Explained:
| GST Exclusive | Adds GST to the base price: Total = Base Price + (Base Price × GST% / 100) |
| GST Inclusive | Extracts embedded GST from gross amount: GST = Total Price - [Total Price / (1 + GST% / 100)] |
| CGST & SGST | Split equally 50:50 for intra-state transactions (within the same state) |
| IGST | Applied in full (100%) for inter-state transactions (across different states) |
GST 18% Exclusive vs Inclusive Example
For an 18% tax bracket, a base price of ₹10,000 attracts ₹1,800 GST, giving an invoice total of ₹11,800. For an inclusive bill of ₹11,800, the pre-tax base value is ₹10,000 and GST is ₹1,800.
Example Input Parameters:
- Base Price (Exclusive) ₹10,000 at 18% GST
- Gross Amount (Inclusive) ₹11,800 at 18% GST
Calculated Output Summary:
- Exclusive Total GST = ₹1,800 | Total Invoice = ₹11,800 (CGST ₹900 + SGST ₹900)
- Inclusive Net Net Base = ₹10,000 | Embedded GST = ₹1,800
