From 1 July 2010, the basis for the calculation of post-judgment interest changed whereby interest is calculated by reference to the Reserve Bank of Australia Cash Rate plus 6%.

This new method of calculating post-judgment interest is intended to apply throughout Australia with amendments having already being made to the NSW Courts Reference

How the Post-Judgment Interest Calculator works:

Interest is calculated using the following methodology contained in the NSW Courts Practice Notes being:

  1. in respect of the period from 1 January to 30 June in any year – the rate that is 6% above the cash rate last published by the Reserve Bank of Australia before that period commenced, and
  2. in respect of the period from 1 July to 31 December in any year – the rate that is 6% above the cash rate last published by the Reserve Bank of Australia before that period commenced

Post-judgment interest is calculated by reference to the Reserve Bank of Australia Cash Rate plus 6% calculated in six month periods. Interest is calculated on a simple basis (not compounding).

The Post-Judgment Interest Calculator has been updated to include the RBA Cash Rate up to 31 December 2011. Next Update: 30 June 2012
