Frequently Asked Questions

What can I calculate with this GST calculator?
Calculate GST amount on any price (add GST to base price or remove GST from inclusive price). Get CGST, SGST, or IGST breakdown. Supports all GST rates: 0%, 5%, 12%, 18%, 28%, and custom rates.
Difference between CGST, SGST, and IGST?
CGST+SGST applies for intra-state (same state) transactions — split equally. IGST applies for inter-state transactions. E.g., 18% GST intra-state = 9% CGST + 9% SGST. Inter-state = 18% IGST.
GST calculation formula?
Add GST: GST Amount = Price × (Rate/100), Total = Price + GST Amount. Remove GST: Base = Total × 100/(100+Rate), GST = Total - Base.
