Find the price before GST from a GST-inclusive price, with CGST and SGST.

You will be asked to sign in or create an account first.

How to use GST Reverse Calculator

  1. Enter the amount and the GST rate.
  2. Choose whether the amount includes GST or excludes it.
  3. Read the price before GST and the GST amount.
  4. Use CGST and SGST for sales in the same state, and IGST for other states.

Good to know: To get the base price from a price that includes GST, divide by 1 plus the rate. Do not just subtract the rate from the total.
