GST calculator

Add GST to a price or remove it from a GST-inclusive price, with the CGST and SGST split.

Estimates only, not financial advice. Values shown are examples. Rates and limits differ by lender and change over time, so enter your own.

How it works

Enter the amount and the GST rate that applies to your item. For a sale within one state, GST is split equally into CGST and SGST. We do not list rates because they can change.
