GST Calculator India – Quickly Calculate CGST, SGST & IGST for Your Business
Goods and Services Tax (GST) has simplified the Indian tax structure, but calculating it correctly can still be confusing—especially when you need to apply different components like CGST, SGST, or IGST. Whether you’re a small business owner, freelancer, or just a curious consumer, a GST calculator makes it easy to break down the tax you’re paying or collecting.
This blog post walks you through how to use the GST Calculator (India) and offers helpful insights to understand how GST works in everyday scenarios.
🧾 What Is GST in India?
GST stands for Goods and Services Tax, a unified indirect tax introduced in 2017. It replaced a range of previous taxes like VAT, service tax, and excise duty. The idea was to create a “one nation, one tax” system to simplify business and reduce cascading taxes.
India’s GST is divided into:
- CGST – Central GST, collected by the central government
- SGST – State GST, collected by the respective state
- IGST – Integrated GST, used for interstate transactions
Understanding these is important for billing, tax filing, or simply checking if your vendor is charging the correct amount.

🏷️ GST Calculation Example
Let’s say you’re a seller offering a product at ₹1,000 and the GST rate is 18%.
- For intra-state:
CGST = ₹90
SGST = ₹90
Total = ₹1,180 - For inter-state:
IGST = ₹180
Total = ₹1,180
If your customer gives you ₹1,180 and it includes GST, you can use the reverse calculation option to determine that the base price was ₹1,000.
