GST Calculator

Calculate GST (Goods and Services Tax) - Add or remove GST from any amount with different tax rates.

What is GST?

GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It replaced multiple cascading taxes levied by the central and state governments. GST is a destination-based tax that is levied at every stage of the production and distribution chain.

GST Tax Slabs in India

GST in India is divided into four main tax slabs:

5% GSTEssential items, basic necessities
12% GSTStandard goods and services
18% GSTMost goods and services
28% GSTLuxury items, sin goods

Understanding CGST and SGST

For intra-state transactions (within the same state), GST is divided equally into:

  • CGST (Central GST): Half of the total GST goes to the Central Government
  • SGST (State GST): Half of the total GST goes to the State Government

For inter-state transactions (between different states), IGST (Integrated GST) is charged instead, which goes to the Central Government.

How to Use This GST Calculator

This calculator can be used in two ways:

  • Add GST: If you have a price excluding GST and want to know the final price including GST
  • Remove GST: If you have a price including GST and want to know the original price and GST amount

GST Calculation Formula

Adding GST:

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

Removing GST:

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