Frequently Asked Questions

What is GST?▼
GST (Goods and Services Tax) is a comprehensive indirect tax on manufacture, sale, and consumption of goods and services at the national level. It replaced multiple indirect taxes in many countries.
How do I calculate GST with an example?▼
Example: For a ₹1,000 product at 18% GST, GST amount = 1,000 × 18% = ₹180. Final price = 1,000 + 180 = ₹1,180. For reverse calculation, if final price is ₹1,180 at 18% GST, base amount = 1,180 ÷ 1.18 = ₹1,000.
What is the difference between inclusive and exclusive GST?▼
