📘 Complete Guide to GST Calculation (India 2025)

Goods and Services Tax (GST) is an indirect tax levied on supply of goods and services. It has replaced many older taxes (VAT, Service Tax, Excise).

🧮 Types of GST:

Formula:

Reverse Charge Mechanism (RCM): Under RCM, the recipient of goods/services is liable to pay GST directly. Common in transportation, legal services, and certain notified goods.

Composition Scheme: For small taxpayers (turnover ≤ ₹1.5 Cr). They pay tax at lower rate (1%, 5%) but cannot claim ITC. Our calculator does not automatically apply composition rates; please select correct rate manually.

Example: Product value ₹10,000, GST 18% (Intra‑state) → CGST = ₹900, SGST = ₹900, Total GST = ₹1,800, Final amount = ₹11,800. For Inter‑state IGST = ₹1,800.
