GST Calculator
Add or remove GST and see the CGST, SGST or IGST split. Useful for Tally and accounts practice.
How GST is worked out
To add GST, the tax is the amount multiplied by the rate, and the total is the amount plus the tax. To remove GST from a price that already includes it, the base amount is the price divided by one plus the rate. For a sale inside one state the tax is split equally into CGST and SGST; for a sale to another state it is charged as IGST.
Enter the rate that applies to your goods or service. GST rates are set by the GST Council and change from time to time, so check the current rate for your item on the official GST portal or with your accountant. The shortcut buttons only fill in a number.
Is this calculator accurate for invoices?
The arithmetic is exact to two decimals, but the rate, the place of supply and any special rules must be confirmed for your own invoice. Use it as a quick check, not as tax advice.
What is the difference between CGST, SGST and IGST?
CGST and SGST are the central and state shares of GST on a sale within a state. IGST is the single tax charged on a sale between states.
