What GST means here

GST is an indirect tax applied to eligible goods and services in India. This calculator helps with quick estimates; the correct treatment depends on the product, place of supply, registration status, and applicable rules.

Add or remove GST

Add GST starts with a taxable amount and calculates the tax on top. Remove GST starts with a tax-inclusive price and separates the embedded GST from the original amount.

CGST, SGST, and IGST

For an intra-state estimate, GST is split evenly between CGST and SGST. For an inter-state estimate, the full tax is shown as IGST. Confirm the applicable treatment before invoicing.
