How the Post-Judgment Interest Calculator works:
Interest is calculated using the following methodology contained in the NSW Courts Practice Notes being:
- 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
- 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 30 June 2012. Next Update: 31 December 2012
Our Post Judgment Interest Calculator calculates interest on the basis of the RBA Cash Rate plus 6%. It does not, at present, include the old Schedule 5 rates prior to 1 July 2010. Calculations will be made prior to 1 July 2010 but it will apply the RBA Cash Rate plus 6% not the NSW Schedule 5 rates.
The change to post-judgment interest does not have retrospective effect – s. 30 Interpretation Act 1987 (NSW). Interest for post-judgment periods up to and including 30 June 2010 should be calculated with reference to the rates in Schedule 5. Practitioners are reminded that they may access historic versions of the UCPR via the NSW Government’s legislation website to review Schedule 5 rates.
