Frequently asked

What is a GST calculator?

A GST calculator works out the GST amount and final price for a sale — either adding GST on top of a base price, or splitting GST out of a price that already includes it.

What's the difference between CGST, SGST and IGST?

CGST and SGST apply together on sales within the same state, splitting the GST rate equally between the central and state governments. IGST applies as a single tax on sales between two different states.

Is this GST calculator free to use?

Yes, this calculator is free with no sign-up required. Creating an account is only needed if you want to save the result as an actual GST invoice with your business and client details.
