Frequently Asked Questions

How to calculate GST amount?

To calculate GST: For GST exclusive price, multiply the price by GST rate (e.g., ₹1000 × 18% = ₹180). For GST inclusive price, use formula: GST Amount = (Price × GST Rate) / (100 + GST Rate).

What are the different GST rates in India?

India has four main GST rates: 5% (essential items), 12% (processed foods), 18% (most goods and services), and 28% (luxury items). Some items like fresh food are exempt (0% GST).

What is the difference between GST inclusive and exclusive?

GST exclusive means the price doesn't include tax (tax is added on top). GST inclusive means the price already includes tax. For example, ₹100 + 18% GST = ₹118 (exclusive), while ₹118 including 18% GST has base price of ₹100 (inclusive).

Can I use this calculator for IGST and CGST+SGST?

Yes, the GST rate remains the same whether it's IGST (interstate) or CGST+SGST (intrastate). For example, 18% GST means either 18% IGST or 9% CGST + 9% SGST.
