What is GST?
GST (Goods and Services Tax) is a destination-based indirect tax applied to the supply of goods and services across India. Introduced on 1st July 2017, GST simplified India's tax structure by replacing various indirect taxes like VAT, Service Tax, Excise Duty, and others.
GST is divided into three major components:
Levied by the Central Government on intra-state transactions.
Levied by the State Government on intra-state sales.
Levied on inter-state sales and imports across states.
The applicable GST depends on whether the transaction is intra-state or inter-state. For specialized commodity calculations such as precious metals, you can also use our specialized Gold Calculator to check gold rates and applicable 3% gold GST.

How Does a GST Calculator Work?

The workflow is simple:
Step 1: Enter Price
Enter the original product or service price.

Common GST slabs include 5%, 12%, 18%, and 28%. Many calculators also allow entering a custom GST percentage.

GST Calculation Formula
Understanding the gst calculation formula helps users verify the results generated by the calculator.
1. Adding GST (Exclusive Mode)
Example: Original Price = ₹10,000 | GST Rate = 18%
GST Amount = ₹10,000 × 18% = ₹1,800
Final Price = ₹10,000 + ₹1,800 = ₹11,800
2. Removing GST (Reverse GST Mode)
Sometimes you already have the final invoice amount and need to determine the original price before GST. This is known as reverse gst calculator functionality.
This feature is extremely useful for businesses that receive GST-inclusive invoices.
