You know your product costs ₹1,000. But how much do you charge the customer once GST is added? Our GST exclusive calculator adds the correct GST amount to any base price — across all Indian tax slabs — giving you the final invoice price in seconds.
What is a GST Exclusive Calculator?
A GST exclusive calculator adds the applicable Goods & Services Tax to a base (pre-tax) price. When a price is listed "exclusive of GST," the buyer pays more than the advertised price. As a seller, business, or B2B buyer, you need to add GST accurately to every invoice, quote, and purchase order.
Formula
GST Amount = Base Price × GST Rate / 100
Total Invoice Price = Base Price + GST Amount
CGST = SGST = GST Amount / 2 (for intra-state transactions)
Example Calculation
A software consulting firm charges ₹50,000 for a project (exclusive of 18% GST).
- GST Amount = ₹50,000 × 18/100 = ₹9,000
- Total Invoice Amount = ₹50,000 + ₹9,000 = ₹59,000
- CGST (9%) = ₹4,500 | SGST (9%) = ₹4,500

FAQs
When is GST charged exclusively vs. inclusively?
B2B invoices almost always show GST exclusively (base + tax = total). Retail consumer goods typically show a GST-inclusive MRP printed on the packaging.
What GST rate applies to services in India?
Most professional services (consulting, legal, IT, accounting) fall under the 18% GST slab. Healthcare, education, and some financial services are exempt.
Do I need a GST number to charge GST?
Yes. Only GST-registered businesses (turnover above ₹20L for services, ₹40L for goods) can charge and collect GST. Registration is also mandatory for e-commerce sellers regardless of turnover.
