What GST rates are available?

The calculator supports all standard Indian GST rates: 5%, 12%, 18%, and 28%. You can also enter a custom rate.

What is the difference between adding and removing GST?

Adding GST calculates the tax on top of your base amount. Removing GST extracts the tax from a GST-inclusive price to find the original base amount.

Does it show CGST and SGST separately?

Yes. For intra-state transactions, GST is split equally into CGST and SGST. For inter-state, the full amount is shown as IGST.
