GST Calculator

Add GST at 5, 12, 18 or 28 percent.

Total (incl. GST)
₹11,800
GST amount
₹1,800
CGST + SGST
₹900 each
Base amount
₹10,000

Enter a base amount and a slab (5, 12, 18, or 28). Exclusive GST is amount × rate/100. Inclusive GST is amount × rate / (100 + rate). Use the matching method for the invoice you have.

Worked example: a ₹1,000 exclusive bill at 18% adds ₹180 tax, ₹1,180 total. If the ₹1,180 is already on the invoice, the tax inside it is 1180 × 18 / 118.

CGST and SGST split that 18% in half on an intra-state invoice. This tool prints the combined GST. It does not print HSN codes.
