About GST Exclusive Calculator
A GST Exclusive price refers to the net base value of a product or service before adding Goods and Services Tax.
When quoting prices to B2B customers, preparing estimates, or issuing invoices, vendors specify base rates as GST exclusive and then add the applicable GST slab (5%, 12%, 18%, or 28%).
Use this tool to calculate the exact GST tax value to be charged and the final grand total payable by the customer.
GST Exclusive Calculation Formula
Adding GST (Exclusive)
GST Amount = Net Base Price × (GST Rate ÷ 100)Removing GST (Reverse / Inclusive)
Grand Total = Net Base Price + GST AmountFor local sales: CGST = GST Amount / 2, SGST = GST Amount / 2. For interstate sales: IGST = GST Amount.
Example: Adding 18% GST to Base Rate ₹10,000
A consulting firm quotes ₹10,000 + GST for advisory services.
Net Base Price₹10,000
GST Rate18%
GST Tax Amount₹1,800
Grand Total Bill₹11,800
Adding 18% GST (₹1,800) to the ₹10,000 net base price results in a final invoice total of ₹11,800.
