Why use GST Exclusive Pricing?
Understanding B2B Transactions
In the business world, especially in B2B (Business to Business) transactions, prices are almost always quoted as “GST Exclusive”.
Input Tax Credit (ITC)
Businesses can claim back the GST they pay. The “real” cost to the business is the base price, not the total.
Clear Invoicing
Tax invoices must legally separate the taxable value (base price) from the tax amount for compliance.

Frequently Asked Questions
Everything you need to know about GST exclusive calculation
What does GST exclusive mean?
GST exclusive means the price does NOT include GST. It's the base price before any tax is added. For example, if a product is priced at ₹10,000 exclusive of GST, you need to add GST (e.g., 18% = ₹1,800) to get the final price of ₹11,800.
How do I calculate GST from exclusive price?
Use the formula: GST Amount = Base Price × Rate / 100. For example, ₹10,000 at 18% GST: GST = 10,000 × 18 / 100 = ₹1,800. Total = Base + GST = ₹10,000 + ₹1,800 = ₹11,800.
What is the difference between GST exclusive and inclusive?
GST Exclusive: Price does NOT include GST - you ADD GST to get the total (₹10,000 + 18% = ₹11,800). GST Inclusive: Price ALREADY includes GST - you EXTRACT GST from the total (₹11,800 contains ₹1,800 GST).
Which GST rate should I use?
India has 4 GST slabs: 5% for essential items (food grains, economy hotels), 12% for standard goods (processed foods, business class tickets), 18% for most services (restaurants, telecom, IT), 28% for luxury items (cars, tobacco, aerated drinks).
Is GST exclusive the default in business transactions?
Yes, in B2B transactions, prices are typically quoted as GST exclusive. This allows businesses to claim Input Tax Credit (ITC). Always clarify with your vendor whether the quoted price includes GST or not.
