The old 12% and 28% slabs are abolished for most goods. Gold stays at 3%. This tool still lets you run legacy 12/28% only for old invoices. Quantity, discount, cess, round-off, composition scheme and a multi-item invoice are built in.

  1. Enter the amount — net price (Add GST) or MRP (Remove GST). Optional qty, discount and cess.
  2. Pick the GST 2.0 slab — 5% essentials, 18% standard, 40% luxury, 0% nil, 3% gold.
  3. Set supply type — intra-state (CGST + SGST), inter-state (IGST), or pick two states.
  4. Read the live breakdown — base, tax split, cess, round-off, grand total.
  5. Copy, print or save — paste into WhatsApp, print a slip, or keep history on this device.

Pro tip: ₹10,000 exclusive at 18% = ₹1,800 GST = ₹11,800 total. Intra-state: CGST ₹900 + SGST ₹900. Inter-state: IGST ₹1,800.

Frequently Asked Questions

GST 2.0 (from 22 September 2025) uses 0% (nil), 5% (essentials), 18% (standard) and 40% (luxury/sin). Gold and silver stay at 3%. The old 12% and 28% slabs are abolished for most goods.
For intra-state sales, GST is split equally. At 18%, CGST is 9% and SGST is 9%. Inter-state sales charge the full rate as IGST with no CGST/SGST split.
Base = Total × 100 ÷ (100 + GST%). Example: ₹11,800 inclusive at 18% → base ₹10,000, GST ₹1,800. Use Remove GST mode.
GST = Amount × Rate ÷ 100. Total = Amount + GST. ₹10,000 + 18% = ₹1,800 GST = ₹11,800.
Not for most goods after 22 Sep 2025. This calculator keeps 12% and 28% as “legacy” so you can recompute old invoices — do not use them on new tax invoices unless a notification still applies to that HSN.
Gold, silver and processed precious stones remain at 3% (1.5% CGST + 1.5% SGST). Rough stones are 0.25%. Making charges on jewellery are often 18% — add them as a separate invoice line.
Composition dealers pay a flat % of turnover (commonly 1% goods, 5% restaurants, 6% services) and generally cannot collect GST from customers or claim ITC. The toggle here is for a quick estimate only.
Yes — unlimited calculations, no signup, no watermark. History is stored only in this browser.
You can print a summary and copy the split. It is not a GST-compliant e-invoice / IRN generator. Add your GSTIN, HSN and place of supply in your billing software.
No. Arithmetic only, based on published GST 2.0 slabs. Confirm HSN/SAC with a CA or CBIC before filing returns.
