How It Works
Australia applies a standard GST rate of 10%. To add GST, the calculator multiplies the net price by 10% and adds it to give the gross price. To remove it, it divides the gross amount by 1.10 to recover the net price and reveal the GST portion. Many basic foods, some health and education services, and certain other items are GST-free.
