Understanding Goods and Services Tax (GST)
Goods and Services Tax (GST) is an indirect tax levied in India and many other countries on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax that replaced almost all other indirect taxes.
Our completely free GST calculator allows you to quickly determine either the total price including tax (Adding GST) or find the original base price of an item if the tax is already included (Removing GST).
The GST Calculation Formulas
To Add GST (Exclusive pricing):
GST Amount = (Original Cost × GST %) / 100
Net Price = Original Cost + GST Amount
Net Price = Original Cost + GST Amount
To Remove GST (Inclusive pricing):
GST Amount = Original Cost - [Original Cost × (100 / (100 + GST %))]
Net Price = Original Cost - GST Amount
Net Price = Original Cost - GST Amount
