GST Formulas
GST Exclusive (Add GST)
GST Amount = Base Price × (GST% ÷ 100)
Total Price = Base Price + GST Amount
Example: ₹1000 + 18% GST = ₹1000 + ₹180 = ₹1,180
GST Inclusive (Remove GST)
Base Price = Total ÷ (1 + GST% ÷ 100)
GST Amount = Total − Base Price
Example: ₹1180 ÷ 1.18 = ₹1000 base, GST = ₹180
