New Calculator: Find the GST Content of a GST Inclusive Price

Posted Tuesday, 1 June 2010 by Brena Smith 

With GST changing from 12.5% to 15% on 1 October 2010 the formula to calculate the GST content of a GST inclusive price also changes. To work out the GST content of a GST inclusive price...

  • With GST at 12.5% divide the GST inclusive price by 9.
  • With GST at 15% multiply the GST inclusive price by 3 then divide that result by 23

To help make this calculation easy (and in case you forget the formula) we've added a new calculator page which does it for you. It handles both 12.5% and 15% which also makes it easy to compare the before / after effect of the GST rate change.
