Base Amount / Original Amount: This is the price of the goods or services before any tax is applied.

CGST & SGST: GST is divided into two components for intra-state (within the same state) transactions. CGST (Central GST) goes to the central government, and SGST (State GST) goes to the state government. Each is exactly half of the total GST rate.

Total GST: The total tax amount applied to the base price (CGST + SGST).

Final Amount / Gross Amount: This is the total price that a customer pays, which includes the base price plus the total GST.

Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax that is levied on every value addition. Understanding it is crucial for both consumers and business owners in India.

What is GST?

GST is an indirect tax that has replaced many other indirect taxes in India such as excise duty, VAT, services tax, etc. It is a single tax on the supply of goods and services, right from the manufacturer to the consumer.

Key Features of this GST Calculator

This tool is designed to be simple yet powerful. Its two primary functions are:

  • Add GST (Forward Calculation): This is the most common scenario. You have a product's base price and want to know the final selling price after adding GST.
    Example: A product costs ₹1,000 + 18% GST. The calculator will show a final price of ₹1,180.
  • Remove GST (Reverse Calculation): This is incredibly useful when you have a final price (MRP) and want to know how much of it was the original price and how much was tax.
    Example: A product's MRP is ₹1,180 (including 18% GST). The calculator will show that the original price was ₹1,000 and the GST amount was ₹180.

Understanding CGST, SGST, and IGST

The type of GST applied depends on where the transaction takes place:

  • CGST (Central GST): Collected by the Central Government on an intra-state sale (e.g., transaction within West Bengal).
  • SGST (State GST): Collected by the State Government on an intra-state sale (e.g., transaction within West Bengal).
  • IGST (Integrated GST): Collected by the Central Government on an inter-state sale (e.g., from West Bengal to Maharashtra).
For any intra-state transaction, the total GST is split equally between CGST and SGST. For example, if the GST rate is 18%, the CGST will be 9% and the SGST will be 9%. This calculator shows this breakdown for you.
