About the GST Calculator
Every invoice in India (and many other countries) needs GST computed in one of two directions: adding tax to a base price, or back-calculating the tax from a GST-inclusive price. This calculator handles both with one toggle. Choose a standard slab — 5%, 12%, 18% or 28% — or enter a custom rate for other jurisdictions, and instantly see the net amount, the GST component and the gross total, plus a CGST/SGST split for intra-state invoices.
How to use the GST Calculator
- Choose Add GST or Remove GST mode.
