GST Calculator
Calculate GST with CGST/SGST/IGST breakdown for all Indian tax slabs.
About GST Calculator
ToolsOfIndia built the GST Calculator for shopkeepers, chartered accountants and billing teams who want straight answers in plain language. Every figure is in Indian rupees with lakh and crore grouping, the same format your bank statements and SIP confirmations already use. Type any amount, pick from the 0, 5, 12, 18 and 28 per cent slabs, and see the CGST, SGST and IGST split instantly along with net and gross totals. Intra-state supplies divide the rate equally between CGST and SGST, while inter-state supplies attract IGST at the full rate. A reverse mode backs the tax out of a GST-inclusive MRP, which is exactly how most retail invoices in India need to be worked, and the quick-slab buttons let you re-run one figure across every rate without retyping anything. The breakdown updates live as you type. Real-world uses include preparing GSTR-1 and GSTR-3B returns, backing the tax out of GST-inclusive MRP stickers, and verifying a vendor invoice before releasing payment. Results update as you type, so you can play what-if games instead of redoing the whole calculation.
