How GST calculation works
Adding GST (exclusive to inclusive): If your base price is ₹10,000 and GST is 18%, the GST amount is ₹1,800 and the total GST-inclusive price is ₹11,800. Formula: GST Amount = Base × Rate/100; Total = Base + GST Amount.
Removing GST (inclusive to exclusive): If a price of ₹11,800 already includes 18% GST, the base price is ₹11,800 / 1.18 = ₹10,000. Formula: Base = Inclusive Price / (1 + Rate/100); GST Amount = Inclusive Price − Base.
