How to Calculate 18% GST
Learn the simple formula to calculate 18% GST with a practical example.
Exclusive GST Formula
GST Amount = Base Amount × 18%
Total Amount = Base Amount + GST Amount
Example: ₹1,000
GST = ₹1,000 × 0.18 = ₹180
Total = ₹1,000 + ₹180 = ₹1,180
Inclusive GST Formula
Base Amount = Total Amount ÷ 1.18
GST Amount = Total Amount - Base Amount
Example: ₹1,180
Base = ₹1,180 ÷ 1.18 = ₹1,000
GST = ₹1,180 - ₹1,000 = ₹180
