GST Calculation Formulas
For GST Exclusive Amount:
- GST Amount = (Base Amount × GST Rate) ÷ 100
- Final Amount = Base Amount + GST Amount
For GST Inclusive Amount:
- Base Amount = Final Amount ÷ (1 + GST Rate ÷ 100)
- GST Amount = Final Amount - Base Amount
Example:
Exclusive Case:
- Base Amount = ₹25,000
- GST Rate = 12%
- GST Amount = ₹25,000 × 12% = ₹3,000
- Final Amount (Exclusive) = ₹25,000 + ₹3,000 = ₹28,000
Inclusive Case:
- Final Amount = ₹28,000
- Base Amount = ₹28,000 ÷ (1 + 12/100) = ₹25,000
- GST Amount = ₹28,000 - ₹25,000 = ₹3,000
