What is GST Calculator?

A GST Calculator is an online tool that calculates the Goods and Services Tax (GST) payable on a given transaction value. It helps businesses and consumers determine the exact GST amount applicable on goods or services based on current GST rates (5%, 12%, 18%, 28%) in India.

Exclusive Method - Add GST to Base Price

Enter the original price before adding GST

How Does the Calculator Work?

Users input the base amount of a product or service and select the applicable GST rate. The calculator then applies the GST formula to compute the GST amount and total price, distinguishing between GST-inclusive and GST-exclusive prices. It also provides a detailed breakup of CGST and SGST as per the nature of the transaction. This helps businesses stay compliant and avoid errors in tax calculations.

  2. GST Rate (%) – The GST rate is the applicable percentage of tax to be levied on the transaction. Common rates under the GST structure include 0%, 5%, 12%, 18%, 28%, and custom rate.
  3. GST Type (Calculation Mode):
