How to use it
- Enter the amount and how many units. Use 1 unit for a single price.
- Choose whether GST is to be added or is already inside the price.
- Pick 0%, 5%, 18%, or 40%, or type another rate, and say if the supply stays in one state.
How the figure is worked out
Exclusive: taxable value = amount × quantity, and GST = taxable value × rate. Inclusive: taxable value = (amount × quantity) ÷ (1 + rate). Same-state GST is split equally into CGST and SGST. Another state is IGST.
Questions
Does this GST calculator file a return?
No. It only shows the tax split for a figure you type. Filing stays on the GST portal.
When do I use IGST instead of CGST and SGST?
Use IGST when the place of supply is in a different state or union territory from the supplier. Use CGST and SGST when it is in the same state. You select that here.
Which GST rate should I pick?
From 22 September 2025 the main rates are 5% and 18%. Nil is 0%. A 40% rate applies to listed luxury and sin goods. Gold is often 3%, which you can type under Other. This page does not look up HSN, and the rate you type is the one used.
How do I remove GST from a price?
Choose Already includes GST. Taxable value = price ÷ (1 + rate). At 18%, a price of ₹118 is ₹100 taxable and ₹18 GST.
Why is CGST equal to SGST?
On a same-state supply the GST rate is split in half. At 18%, CGST is 9% and SGST is 9%. Another state shows the full rate as IGST.
