What is GST (Goods and Services Tax)?

The Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. Implemented on July 1, 2017, GST replaced multiple indirect taxes like VAT, Service Tax, Central Excise, and others, creating a unified tax system across the country.

GST is a destination-based tax that follows the principle of "One Nation, One Tax." It has simplified the tax structure and reduced the cascading effect of taxes, making it easier for businesses to comply with tax regulations.

How to Calculate GST? - Step-by-Step Guide

Calculating GST is straightforward when you understand the basic formulas. Our GST calculator automates these calculations, but it's important to understand the underlying math.

GST Calculation Formulas

🔢 Adding GST to Base Amount

GST Amount = (Base Amount × GST Rate) ÷ 100
Total Amount = Base Amount + GST Amount
Example: Base Amount = ₹1,000, GST Rate = 18%
GST Amount = (1,000 × 18) ÷ 100 = ₹180
Total Amount = ₹1,000 + ₹180 = ₹1,180

🔄 Extracting GST from Total Amount

Base Amount = (Total Amount × 100) ÷ (100 + GST Rate)
GST Amount = Total Amount - Base Amount
Example: Total Amount = ₹1,180, GST Rate = 18%
Base Amount = (1,180 × 100) ÷ (100 + 18) = ₹1,000
GST Amount = ₹1,180 - ₹1,000 = ₹180

CGST and SGST Calculation

For intra-state transactions, GST is split equally between CGST and SGST:

Example: For 18% GST rate:
CGST = 18% ÷ 2 = 9%
SGST = 18% ÷ 2 = 9%
