What is GST? (Goods & Service Tax) 💡

GST, or Goods and Services Tax, is a unified indirect tax levied on the supply of goods and services across India. It replaces a complex system of multiple indirect taxes and promotes transparency, simplicity, and efficiency in taxation. Whether you're a business owner, freelancer, or consumer, understanding GST is essential for accurate billing and tax compliance.

Formula Used by Our GST Calculator 🧮

Our GST Calculator uses standard government-approved formulas to ensure accurate results for both GST-inclusive and GST-exclusive amounts.

1. For GST Exclusive Amount (Adding GST):

GST Amount = (Original Cost × GST Rate) / 100 Total Cost = Original Cost + GST Amount

2. For GST Inclusive Amount (Removing GST):

GST Amount = Original Cost - [Original Cost × 100 / (100 + GST Rate)] Base Price = Original Cost - GST Amount

This tool supports all major GST slabs in India, 5%, 12%, 18%, and 28% - making it ideal for invoices, price analysis, and tax breakdowns.
