GST Rate Finder India 2025 — HSN & SAC Code Rate Lookup
CGST · SGST · IGST Breakdown — Invoice, Reverse GST & Business Summary
HSN (Harmonised System of Nomenclature) codes classify goods for GST. SAC (Services Accounting Code) classifies services. Using wrong HSN/SAC code leads to GST misclassification — you either overpay or underpay tax (both are problematic). Businesses with turnover above ₹5Cr must mandatorily mention 6-digit HSN. This tool helps find correct GST rate for common goods and services with their HSN/SAC codes.

How to Use GST Calculator India
Enter the base amount, select the GST rate slab (5%, 12%, 18%, 28%), choose Exclusive (add GST to amount) or Inclusive (extract GST from total), and select whether it's an Intra-state (CGST + SGST) or Inter-state (IGST) transaction. Get instant breakup — no login, no install.
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.
