What is a GST Calculator?

A Goods and Services Tax (GST) Calculator helps business owners, consumers, and accountants easily calculate the gross or net price of a product by adding or removing the applicable GST rate.

How to Use This Calculator

  1. Enter the net price of the item (or gross price if removing GST).
  2. Select the applicable GST slab (e.g., 5%, 12%, 18%, 28%).
  3. Choose whether to Add GST (find total price) or Remove GST (find base price).
