GST Exclusive Formula
If GST is not included in the original amount:
GST Amount = Original Amount × GST Rate ÷ 100
Final Amount = Original Amount + GST

Product price = ₹10,000
GST rate = 18%
GST = ₹10,000 × 18 ÷ 100 = ₹1,800
Final invoice amount = ₹11,800
GST Inclusive Formula
If GST is already included in the total amount:
GST Amount = Inclusive Amount × GST Rate ÷ (100 + GST Rate)
Example
Inclusive amount = ₹11,800
GST rate = 18%
GST = ₹11,800 × 18 ÷ 118 = ₹1,800
