What is GST (Goods and Services Tax)?

Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax levied on every value addition. It has replaced multiple indirect taxes in India, simplifying the tax structure and making it more transparent.

GST Calculation Methods

GST Exclusive (Add GST): When price doesn't include GST, GST amount = (Original Cost × GST Rate) / 100. Total Amount = Original Cost + GST Amount.

GST Inclusive (Remove GST): When price includes GST, GST Amount = Total Amount - (Total Amount × 100 / (100 + GST Rate)). Net Amount = Total Amount - GST Amount.

GST Slabs in India

• 0% (Nil Rated): Essential items like fresh fruits, vegetables, milk, eggs
• 5%: Household necessities, packaged food items, coal
• 12%: Processed food, computers, business class air tickets
• 18%: Most goods and services including AC restaurants, telecom services, IT services
• 28%: Luxury items, sin goods like cigarettes, aerated drinks, luxury cars

Example Calculation

GST Exclusive: Product price ₹10,000 + 18% GST = ₹10,000 + ₹1,800 = ₹11,800
GST Inclusive: Total price ₹11,800, GST = ₹1,800, Net = ₹10,000
