FAQ
How is GST calculated?
Adding GST: price × (1 + rate ÷ 100). Removing GST: price ÷ (1 + rate ÷ 100).
What are CGST and SGST?
For sales within a state, GST splits equally into central (CGST) and state (SGST) halves. For inter-state sales the full amount is IGST.
Which GST rates are valid?
Check the current slabs on the official GST portal — rates and goods categories change. You can enter any rate here.

No. It’s a calculator; confirm figures with your invoice or accountant.
