About GST Calculation in India
GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply
of goods and services in India, replacing multiple cascading taxes like VAT, Service Tax, and Excise Duty.
GST was implemented on 1 July 2017 under the One Nation, One Tax framework.
How GST is calculated: For a base amount of ₹10,000 at 18% GST:
Intra-state: CGST (9%) = ₹900 + SGST (9%) = ₹900 → Total = ₹11,800.
Inter-state: IGST (18%) = ₹1,800 → Total = ₹11,800.
Reverse GST calculation: To find the base price from an inclusive amount at 18%:
Base = Inclusive Price ÷ 1.18. For ₹11,800 → ₹11,800 ÷ 1.18 = ₹10,000 base + ₹1,800 GST.
