GST Calculation Formula
GST calculation depends on whether you want to add GST or remove GST.
1. Formula to Add GST
GST Amount = (Original Price * GST Rate)/100
Final Price Formula
Final Price = Original Price + GST Amount
Example
Original Price = ₹1000
GST Rate = 18%
GST Amount = (1000 × 18) / 100
GST Amount = ₹180
Final Price = ₹1180
2. Formula to Remove GST
If you already have the GST-inclusive price, you can calculate the original price.
Original Price = (Final Price * 100) / (1 + GST Rate)
Example
Final Price = ₹1180
GST Rate = 18%
Original Price = 1180 / 1.18
Original Price = ₹1000
GST Amount = ₹180
CGST, SGST and IGST Explained
GST in India is divided into three components.
CGST (Central GST)
Collected by the Central Government.
SGST (State GST)
Collected by the State Government.
IGST (Integrated GST)
Applied to interstate transactions.
Example
For 18% GST
CGST = 9%
SGST = 9%
If product price = ₹1000
CGST = ₹90
SGST = ₹90
Total GST = ₹180
