How GST Calculator Works — Formula
GST Exclusive: GST Amount = Base × Rate/100 · Total = Base + GST
GST Inclusive (Reverse): Base = Total ÷ (1 + Rate/100) · GST = Total − Base
CGST & SGST = GST Amount ÷ 2 each (for intra-state transactions).
Example: ₹10,000 base at 18% → GST = ₹1,800 · CGST = ₹900 · SGST = ₹900 · Total = ₹11,800.
CGST vs SGST vs IGST — What's the Difference?
CGST (Central GST) goes to Central Government. SGST (State GST) goes to State Government. Both are charged on intra-state transactions (seller and buyer in the same state), each at half the total GST rate. IGST (Integrated GST) is charged on inter-state transactions and goes entirely to the Central Government, which then distributes to the destination state.
