GST Calculator lets you computes GST-inclusive and GST-exclusive amounts for Indian tax slabs (5%, 12%, 18%, 28%) with automatic HSN/SAC code hints.. Everything runs inside your browser — nothing is uploaded to a server. It works on any device with a modern web browser.
This calculator supports all four standard Indian GST slabs: 5% (essentials like packaged food), 12% (processed goods), 18% (most services and regular items), and 28% (luxury goods and sin products).
Add GST calculates the final price including tax starting from a net/exclusive amount (e.g., ₹1000 + 18% GST = ₹1180). Remove GST works backwards from a gross/inclusive total to extract the original net amount and the GST component (e.g., ₹1180 with 18% GST = ₹1000 net + ₹180 tax).
This calculator is designed for quick estimates and personal use. For official GST filing or professional invoices, use the GST Invoice Generator tool and consult a tax professional.
The calculator works with standard GST rates. IGST applies to inter-state transactions at the same slab rates, and the calculation method is identical — the total tax percentage is the same whether it's CGST+SGST (intra-state) or IGST (inter-state).
