About the GST calculator

GST is added to most goods and services in India. Within a state it is split equally into CGST and SGST; for sales between states it is charged as IGST at the full rate.

Choose whether to add GST to a price or to find the GST already included in it, and pick the rate.

How to use it

  1. Move the sliders, or type a value into each box.
  2. Watch the results and chart update as you go.
  3. Try different assumptions to see what changes the outcome most, then talk to us about a plan.

The formula

Add GST: GST = amount × rate · Remove GST: net = amount ÷ (1 + rate), GST = amount − net

  • CGST = SGST = GST ÷ 2 (sales within a state)

Example

₹10,000 plus 18% GST is ₹11,800: ₹900 CGST + ₹900 SGST. A price of ₹11,800 including 18% GST has a net value of ₹10,000.

Rates shown follow the simplified GST structure (5%, 18% and 40%, plus 3% for items such as gold). Check the rate that applies to your goods or services.
