GST Calculator
Calculate GST amount for any product or service.
What is GST Calculator?
The Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. A GST calculator helps you compute the GST amount and the total price for a given base price and GST rate.
GST rates in India range from 0% to 28% depending on the category of goods or services. This calculator works for both adding GST to a price and removing GST from an inclusive price.
How does the GST Calculator work?
For example, if the base price is ₹10,000 and the GST rate is 18%, the GST amount is ₹1,800 and the total price is ₹11,800.
If the price already includes GST, the calculator can work backwards to find the base price and the GST component.

- Enter the base price of the product or service.
- Select the applicable GST rate (5%, 12%, 18%, or 28%).
