About this Tool
Goods and Services Tax (GST) is added to the base price of most goods and services in India. This calculator converts between GST-exclusive and GST-inclusive prices at any rate, and splits the tax into equal CGST and SGST halves for intra-state sales.

Check that a supplier's bill splits tax correctly into CGST and SGST halves.
Reverse Calculation
Back out the tax from an MRP to find the true base price and margin.
Business Quoting
Quote clients cleanly with base price, tax, and total shown separately.
