How GST is Calculated
Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes like VAT, Central Excise, and Service Tax. GST can be calculated either by adding tax to the base price (Exclusive) or by extracting tax from the total bill (Inclusive).
GST Calculation Formulas
GST Exclusive (Add GST to Base)
GST Amount = Original Cost × (GST Rate / 100)
Total Amount = Original Cost + GST Amount
GST Inclusive (Remove GST from Total)
Original Cost = Total Amount × [100 / (100 + GST Rate)]
GST Amount = Total Amount - Original Cost
Example: Intra-State vs Inter-State
For a base amount of ₹10,000 with 18% GST:
Intra-State (Within State)
CGST = 9% = ₹900
SGST = 9% = ₹900
Total GST = ₹1,800
Inter-State (Across States)
IGST = 18% = ₹1,800
CGST = 0, SGST = 0
Total GST = ₹1,800
