GST = Base Amount × (Rate ÷ 100); Final Invoice Amount = Base Amount + GSTGST exclusive calculator for pre-tax amounts. Adds GST on top of base price for invoices and quotations.
GST exclusive means the quoted price is before tax. GST is added on top to arrive at the final invoice amount. This is standard for B2B quotations, professional service fees, and many vendor invoices where tax is shown as a separate line item.
GST = Base Amount × (GST Rate ÷ 100). Final Invoice Amount = Base Amount + GST. For ₹10,000 base at 18% GST: GST = ₹1,800; Final Invoice = ₹11,800.
Total GST splits into CGST and SGST (50% each) for intra-state supplies, or IGST at the full rate for inter-state supplies. This calculator shows indicative splits alongside total GST.
Example 1 (18%): Base ₹10,000 → GST ₹1,800 → Invoice ₹11,800. CGST ₹900 + SGST ₹900. | Example 2 (5%): Base ₹50,000 → GST ₹2,500 → Invoice ₹52,500. | Example 3 (12%): Base ₹5,000 → GST ₹600 → Invoice ₹5,600. | Example 4 (28%): Base ₹10,000 → GST ₹2,800 → Invoice ₹12,800.
