About This Tool

The GST Calculator works out Goods and Services Tax for India in both directions. In Add mode it treats your amount as the pre-tax base and adds GST to give the final price. In Remove mode it treats your amount as GST-inclusive and extracts the base and tax. It also splits the tax into CGST and SGST, each half of the total GST for intra-state transactions.

Calculations run in your browser at the rate you select (5%, 12%, 18%, 28%, and more).
