GST Calculation Formula
GST Exclusive Formula
If GST is not included:
GST Amount = Original Amount × GST Rate ÷ 100
Final Amount = Original Amount + GST
Example:
Price = ₹10,000
GST = 18%
GST Amount = ₹1,800
Final Price = ₹11,800
GST Inclusive Formula
If GST is already included:
GST Amount = Inclusive Amount × GST Rate ÷ (100 + GST Rate)
Example:
Inclusive Price = ₹11,800
GST = ₹1,800
Original Price = ₹10,000
This is why businesses use GST Inclusive and Exclusive Calculators for accuracy.
