TopToolAIIndia GST Calculator
Calculate India GST (Goods and Services Tax) at any of the standard slabs — 5%, 12%, 18% or 28% — either adding GST on top or extracting it from a tax-inclusive total. A ₹1,000 item under the 18% slab comes to ₹1,180 total, while the same item under the 5% slab, applied to many essential goods, comes to just ₹1,050 — the four slabs exist specifically to tax essentials lower than luxury items.
