How GST Works
What is GST?
Goods and Services Tax (GST) is India's unified indirect tax replacing VAT, service tax, and excise duty. It's applied at each stage of supply chain.
CGST vs SGST vs IGST
Intra-state (within same state): GST is split equally into CGST (Central) and SGST (State). Inter-state (cross-state): Full IGST applies, collected by Centre.
Inclusive vs Exclusive
Exclusive (Add GST): Your price is the base; GST is added on top. Inclusive (Remove GST): Your price already includes GST; calculator extracts the base and tax.
Formula
Add: GST = Base × Rate%
Remove: Base = Total ÷ (1 + Rate%)
CGST = SGST = Total GST ÷ 2
