CGST, SGST and IGST Explained

  • SGST — State GST (goes to State Government)
  • IGST — Inter-state GST (for goods crossing state borders)

Frequently Asked Questions

How is GST calculated?

To add GST, multiply the base amount by the GST rate and add it to the original price. To remove GST from a total, divide by one plus the rate to find the original amount.

What are the common GST rates in India?

GST is charged at several slab rates depending on the goods or service. Always check the current applicable rate for your specific product, as rates can be revised by the government.

What is the difference between CGST, SGST, and IGST?

For sales within a state, GST is split equally into CGST and SGST. For sales between states, a single IGST is charged instead. The calculator shows this breakup for you.
