net benefit assumptions

Industry Super Australia have commissioned SuperRatings to undertake the research and modelling for use in some of its advertisements.

SuperRatings is a ratings, research and consulting company that specialises in analysing super funds, their investment returns, fees and the relative benefits they offer.

The Net Benefit Model, prepared by SuperRatings, calculates the variance in earnings and fees between HESTA and retail super funds (also known as retail master trusts), over different time peiods, with the default comparison being the 15 years to 30 June 2019.


Sample set: the sample set used in the modelling contains HESTA and the retail super funds with a 5, 10 and 15 year performance history which are actively tracked by SuperRatings, including superannuation investment products that are open and those that are closed to new members but continue to hold assets.


Timeframe  1 yr 3 yr 5 yr 7 yr 10 yr 15 yr
Retail super products  166 147 133 84 67 44
  • The model uses the main balanced investment option (being the balanced investment option with the highest level of assets) offered by each product provider in the sample set. 
  • The model uses return and fee data that is submitted by funds to SuperRatings, made publicly available by funds or contained within formal fund disclosures as at 30 June each year. 
  • Using the starting account balance and salary, the contributions, earnings and fees are calculated using 30 June data each year to derive the closing account balance at the end of each year. 
  • The closing account balance for the previous year is then used to calculate earnings and fees on the account in the following years with the process being repeated for each year of the comparison. 
  • The net benefit for each product refers to the cumulative earnings less fees for the relevant comparison period. 
  • The average net benefit of retail super funds is calculated by taking an average of all net benefit outcomes at the end of the comparison period for the retail products actively tracked by SuperRatings, with a 5, 10 and 15 year performance history. 
  • The net benefit is calculated for each product which has sufficient return and performance history information available over the entire comparison period. Where this information is not available, those products are excluded from the calculation.  
  • The model assumes no additional contributions or withdrawals over the relevant comparison period. 
  • The model will be updated annually with 30 June figures (available in approximately October each year), and the outcomes will be reviewed quarterly.
