When you have a base amount and need to add GST:
Inclusive = Base + (Base × GST/100)
GST = Base × GST/100
When the total already includes GST:
Base = Inclusive / (1 + GST/100)
GST = Inclusive - Base
What is GST? – Goods and Services Tax (GST) is a value‑added tax levied on most goods and services sold for domestic consumption. In India, it is divided into two components: CGST (Central GST) and SGST (State GST), each typically half of the total GST rate for intra‑state transactions. For inter‑state supplies, IGST (Integrated GST) is applied (not shown separately in this calculator).
If the base price (excluding GST) is P and the GST rate is r%:
If the total inclusive amount is T and you need the base price:
For example, if you have a base price of ₹1,000 and GST is 18%, the GST is ₹180, and the total is ₹1,180. Conversely, if you see a price of ₹1,180 including 18% GST, the base price is ₹1,180 / 1.18 = ₹1,000.
For intra‑state sales, the total GST is divided equally into CGST and SGST. So at 18% GST, CGST = SGST = 9% each. Our calculator automatically shows this split. For inter‑state sales, IGST applies as a single tax (not split).
