What is GST?
GST, or Goods and Services Tax, is a comprehensive indirect tax levied on the supply of goods and services in India. Introduced on July 1, 2017, GST has replaced multiple indirect taxes like VAT, service tax, excise duty, etc., creating a unified tax structure across the country.
Types of GST in India
- CGST – Central Goods and Services Tax (levied by the central government)
- SGST – State Goods and Services Tax (levied by state governments)
- IGST – Integrated Goods and Services Tax (levied on inter-state transactions)
- UTGST – Union Territory GST (levied in Union Territories)
How is GST Calculated?
GST can be calculated using the formula:
Final Price = Original Cost + GST Amount
Example: If an item costs ₹1,000 and GST is 18%, then GST amount is ₹180, and final price is ₹1,180.

What Are the Current GST Rates in India?
- 0% – Essential items (milk, fresh vegetables, most food grains)
- 5% – Household essentials, apparel, medicines and most daily-use goods
- 18% – The standard rate for most goods and services (electronics, soaps, restaurant services)
- 40% – Luxury and sin goods (tobacco, aerated drinks, high-end cars)
- Special: 0.25% on rough diamonds and 3% on gold, silver and jewellery
Under the GST 2.0 reform effective 22 September 2025, the earlier 12% and 28% slabs were removed — their items were re-mapped into the 5% or 18% rate, with a new 40% rate added for luxury and sin goods.

What’s the Difference Between Input and Output GST?
Input GST is the tax paid on purchases, while output GST is the tax collected on sales. The net GST payable = Output GST – Input GST.
Inclusive vs Exclusive GST Price: What’s the Difference?
- Exclusive GST – GST is added over base price
- Inclusive GST – Total price already includes GST
Use the calculator mode toggle to switch between exclusive and inclusive calculations.
