How to calculate 18% GST
To add 18% GST to a base price:
GST Amount = Base Price x 18% = Base Price x 0.18
Total Price = Base Price + GST Amount
To remove 18% GST from a GST-inclusive price:
Base Price = Total Price / 1.18
GST Amount = Total Price - Base Price
For intra-state supply, GST splits equally into CGST and SGST (each 9%). For inter-state supply, the full 18% applies as IGST.
