How to use GST Calculator (GST 2.0)
Enter the amount, say whether it already includes GST, then pick the rate and the type of supply. The table compares every GST 2.0 slab for the same amount.
How it works
Adding GST: total = amount × (1 + rate). Removing it: amount before GST = total ÷ (1 + rate). Within a state the tax is split equally into CGST and SGST/UTGST; between states and on imports it is IGST.
Example
1,000 before GST at 18 % within one state gives 90 CGST + 90 SGST, a total of 1,180.
