About the GST Calculator
Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. Our free GST Calculator India helps you quickly compute the GST amount and calculate both GST-inclusive and GST-exclusive prices.
How to Add GST (Exclusive to Inclusive)
If you have the base price and want to find the final price including GST:
GST Amount = Base Amount × (GST% / 100)
Total Amount = Base Amount + GST Amount
Total Amount = Base Amount + GST Amount
How to Remove GST (Inclusive to Exclusive)
If you have the final price and want to find the original price before GST:
Base Amount = Total Amount / (1 + (GST% / 100))
GST Amount = Total Amount - Base Amount
GST Amount = Total Amount - Base Amount
