What is GST?

GST is generally charged at different rates such as:
- 5% GST
- 12% GST
- 18% GST
- 28% GST
The applicable rate depends on the product or service being sold.

How GST is Calculated
Adding GST
Formula:
GST Amount = Original Amount × GST Rate ÷ 100
Final Amount = Original Amount + GST Amount
Removing GST
Formula:
Original Amount = Final Amount ÷ (1 + GST Rate/100)
These calculations can be performed automatically using the ToolGPT GST Calculator.
Example 1: Add GST
Suppose a product costs ₹10,000 and GST is 18%.
GST Amount:
10,000 × 18 ÷ 100 = ₹1,800
Final Amount:
₹10,000 + ₹1,800 = ₹11,800
Example 2: Remove GST
Suppose the total bill amount is ₹11,800 including 18% GST.
Original Amount:
₹11,800 ÷ 1.18 = ₹10,000
GST Amount:
₹11,800 − ₹10,000 = ₹1,800
