Understand the formulas used in this calculator
GST is added to the base amount. Used when price is shown without GST.
GST Amount = Base Amount × (GST Rate / 100)
Total Amount = Base Amount + GST Amount
Example: Base ₹10,000 at 18% GST
GST = 10,000 × 18% = ₹1,800 | Total = ₹11,800
GST is already included in the price. Used when price is shown with GST.
Base Amount = Total Amount / (1 + GST Rate/100)
GST Amount = Total Amount - Base Amount
Example: Total ₹11,800 at 18% GST
Base = 11,800 / 1.18 = ₹10,000 | GST = ₹1,800
