GST Calculation Methods
1. Forward Calculation (Adding GST)
Formula: Final Amount = Original Amount × (1 + GST Rate)
Example: For ₹1000 with 18% GST:
- GST Amount = 1000 × 18% = ₹180
- Final Amount = 1000 + 180 = ₹1180
2. Reverse Calculation (Removing GST)
Formula: Original Amount = Final Amount ÷ (1 + GST Rate)
Example: From ₹1180 with 18% GST:
- Original Amount = 1180 ÷ 1.18 = ₹1000
- GST Amount = 1180 - 1000 = ₹180
