What is GST Inclusive?
GST Inclusive pricing means the displayed amount already contains GST.
The customer pays exactly the amount shown.
Example of GST Inclusive Pricing
A product is sold for ₹1,180 including 18% GST.
The GST component is already included inside ₹1,180.
To find the original price before GST, you must remove GST from the total amount.
GST Inclusive Formula
Base Amount = Total Amount ÷ (1 + GST Rate/100)
Example:
Total Amount = ₹1,180 GST Rate = 18% Base Amount = 1180 ÷ 1.18 = ₹1,000 GST = ₹180
What is GST Exclusive?
GST Exclusive pricing means GST is not included in the displayed amount.
The GST amount is calculated and added separately.
Example of GST Exclusive Pricing
A supplier quotes:
₹1,000 + GST @18%
GST = ₹180 Final Amount = ₹1,180
GST Exclusive Formula
Final Amount = Base Amount × (1 + GST Rate/100)
GST Inclusive Formula
Taxable Value = Inclusive Price × 100 ÷ (100 + GST Rate)
Example:
₹1,180 x 100 ÷ 118 = ₹1,000
This formula works regardless of the amount. For a detailed explanation of reverse GST calculation, see What Does GST Inclusive Mean?
