GST Calculator
Calculate Goods and Services Tax (Exclusive / Inclusive).
GST (Goods and Services Tax) is an indirect tax used in India. Calculations depend on whether the price is exclusive (GST added on top) or inclusive (GST already included).
GST Formulas
GST Exclusive: Total = Cost + (Cost × GST%)
Example: ₹1000 + 18% GST = 1000 + 180 = ₹1180
GST Inclusive: Original Cost = Total × [100 / (100 + GST%)]
Example: ₹1180 inclusive of 18% GST:
Original = 1180 × [100/118] = ₹1000
