How gst in India is calculated
These figures come from **Notification No. 9/2025-Integrated Tax (Rate)**, dated 17 September 2025 and in force from 22 September 2025, which superseded the 2017 rate notification. It notifies the rate of integrated tax as *"(i) 5 per cent. in respect of goods specified in Schedule I, (ii) 18 per cent. ... Schedule II, (iii) 40 per cent. ... Schedule III (iv) 3 per cent. ... Schedule IV, (v) 0.25 per cent. ... Schedule V, (vi) 1.50 per cent. ... Schedule VI, and (vii) 28 per cent. ... Schedule VII"*.
**That is seven rates, and it matters because the 2025 reform is almost universally described as leaving three.** Summaries of GST 2.0 say the slabs became nil, 5%, 18% and 40%, with 12% and 28% abolished. The notification itself keeps **28% in Schedule VII**, alongside 3%, 1.5% and 0.25% for precious metals and stones. For most groceries the popular summary is harmless; for a jeweller or a car dealer it omits the band they actually charge. This page follows the notification.
Which schedule a good falls in is decided by its **tariff heading**, not by a category you can reason about, so the options here name the schedule rather than guessing at a description. The rates shown are the **integrated** tax rates, charged on inter-state supplies. An intra-state supply carries the same total split equally between CGST and SGST — 9% and 9% rather than 18% — so the figure on the invoice is the same and this calculator is right either way. This page covers the rate schedules only.

Frequently asked questions
What are the GST rates in India?
Seven: 18% (Schedule II, the general rate), 5%, 28%, 40%, 3%, 1.5% and 0.25%, all set by CBIC Notification No. 9/2025-Integrated Tax (Rate) in force since 22 September 2025.
How much GST is on 1,000 rupees?
180 rupees at the general 18% rate, for 1,180 total. At 5% it is 50 rupees and at 40% it is 400 rupees.
Was the 28% GST slab abolished in 2025?
No. Most summaries of the 2025 reform say GST became nil, 5%, 18% and 40%, but the rate notification itself still lists 28% for goods in Schedule VII — along with 3%, 1.5% and 0.25% for precious metals and stones.
Is this CGST, SGST or IGST?
The rates shown are the integrated (IGST) rates charged on inter-state supplies. An intra-state supply carries the same total split equally between CGST and SGST — 9% plus 9% instead of 18% — so the amount on the invoice is identical.
