GST Calculator
Calculate GST for any amount and rate. Covers all Indian states and union territories with automatic CGST, SGST, IGST and UTGST breakup.
About this GST Calculator
Supports both Tax Exclusive (add GST to a base price) and Tax Inclusive (extract GST from a total). Uses current slabs per the 56th GST Council — 0%, 0.25%, 3%, 5%, 18%, 28%, and 40%.
Select merchant and customer state to automatically determine whether IGST (inter-state), CGST + SGST (intra-state), or CGST + UTGST (union territory) applies.
Frequently Asked Questions
What is the difference between Tax Exclusive and Tax Inclusive?
Tax Exclusive means the price does not include GST — tax is added on top. Tax Inclusive means GST is already built into the price you enter, and this calculator extracts the base and tax from it.
When does IGST apply instead of CGST + SGST?
IGST applies when the merchant and customer are in different states (inter-state supply). For same-state transactions, GST is split equally as CGST + SGST (or CGST + UTGST for union territories).
What is UTGST and when does it apply?
UTGST replaces SGST for Union Territories without their own legislature — Chandigarh, Lakshadweep, Andaman & Nicobar, Daman & Diu, Dadra & Nagar Haveli, and Ladakh.
Is the 12% GST slab still applicable?
No — the 12% slab was abolished by the 56th GST Council effective 22 September 2025. Goods previously taxed at 12% have been moved to either 5% or 18%. This calculator only shows current slabs.
