What is GST Calculator?
The GST calculator helps businesses and consumers calculate the GST amount on any transaction — both inclusive (when price includes GST) and exclusive (when GST needs to be added). India has four main GST slabs: 5%, 12%, 18%, and 28%. Essential goods are exempt or taxed at 5%, while luxury and sin goods attract 28%. The calculator also splits GST into CGST + SGST (intra-state) or IGST (inter-state).
📐 Formula Used
Exclusive (adding GST): GST Amount = Base Price × GST Rate / 100 Inclusive (removing GST): Base Price = Total Price / (1 + GST Rate/100)
📖 How to Use
Select whether you want to add GST or remove it from a price. Choose the GST rate (0%, 5%, 12%, 18%, or 28%) and enter the amount. The calculator shows base price, GST amount, total, and CGST/SGST split.
