About this calculator
India's GST applies in slabs: 5%, 12%, 18% and 28%, with 18% covering the widest range of goods and services. At 18%, a ₹100 net price carries ₹18 of GST for a ₹118 total. Change the rate field to match your item's slab.
Within India, the GST charged is split equally between central and state government (CGST + SGST) for intra-state sales, or charged as IGST for inter-state sales — the total rate is the same either way. Essentials like unbranded food staples are exempt, while some luxury and sin goods attract 28% plus cess.
Registered businesses charge GST on sales and claim input tax credit on purchases through their GST returns; the GST Council sets the authoritative slab classifications.

Frequently asked questions
What are India's GST slabs?
The rates are 5%, 12%, 18% and 28%, with 18% covering the widest range of goods and services. A ₹100 item at 18% costs ₹118; at 28% it costs ₹128.
How do I remove GST from an inclusive price?
Divide by 1 plus the slab rate. A ₹118 price at 18% is ₹100 net with ₹18 of GST; at the 5% slab, divide the inclusive price by 1.05.
Are CGST and SGST charged on top of these rates?
No. For an intra-state sale the slab is split equally into CGST and SGST — 18% is 9% plus 9% — so the total you pay is the slab rate, not double it. Inter-state sales charge the same rate as a single IGST.
