How do investments affect my final PSS benefit?

I’m a contributing member

If you are a contributing member, your total final PSS defined benefit is largely unaffected by investment performance because it is ‘defined’ by a set formula based on:

  • your final average salary (FAS)
  • your contribution rate
  • your length of PSS membership.

However, transfer amounts into PSS after 1995 and any super co-contribution amounts you receive are affected by investment performance. Ultimately, how much you contribute to PSS will determine your final benefit.


I’m a preserved or associate member

If you are a preserved or an associate member, investment performance more directly impacts your benefit because your total benefit is no longer defined by a set formula. Taxed components (your member and productivity components) move in line with scheme earnings which may be positive or negative; untaxed components (your employer-financed component) continue to grow in line with the Consumer Price Index.


Do I have investment choice?

Only preserved benefit and associate members have investment choice; you can elect to switch to the Cash Investment Option if you wish. However, all members may find it useful to learn how PSS performs.
