Online GST Calculator

A GST Calculator is an online tool that helps businesses, freelancers, and individuals calculate the GST payable on any product or service. GST is applied based on certain tax slabs, and knowing the exact amount of GST can help businesses maintain compliance and avoid any legal issues.

There are two ways to calculate GST:

  1. Inclusive GST – The GST is already included in the price.

  2. Exclusive GST – The GST is added separately to the price of the product or service.

A GST Calculator can compute either, depending on your needs, saving you time and ensuring accuracy.

Total Amount = Original Cost + GST Amount

To Remove GST (Exclusive Pricing):

Original Cost = (Total Amount × 100) / (100 + GST%)
GST Amount = Total Amount - Original Cost

Example: For ₹1,000 at 18% GST:

  • GST = ₹180

  • Total = ₹1,180
