About this tool
Calculate GST the way Indian invoices show it. Choose whether your amount already includes GST or not, pick the slab, and see the base amount, GST amount, and the CGST/SGST split.
Frequently asked questions
What are the common GST slabs in India?
The commonly used GST slabs are 5%, 12%, 18% and 28%, depending on the category of goods or service. This tool lets you enter any custom rate too.
What is the difference between CGST and SGST?
For sales within the same state, GST is split equally into CGST (central) and SGST (state), each being half the total GST rate. For inter-state sales, the full amount is charged as IGST instead.
How do I remove GST from a price that already includes it?
Select 'Remove GST from amount' and enter the final price — the tool will back-calculate the original base amount and the GST portion.
