What happens to my pension contributions under the SPSS if one were to quit a public sector job to go into the private sector after 5 years? Would I be able to get my payments back? (I don't think so!) Otherwise, how would I figure out how much of a pension I'd be entitled to when I retire in 30-odd years?
You can only take them out within 2 years. After that not.
I don't know the answer to what happens going forward sorry.
You may be able to work out what it is worth now, and the hope would be increases in pay for your grade(s) match inflation in the future.
It's based on a career averaged salary so is very particular to your situ. See if this helps:
Google deferred benefit + single scheme. There may also be a calculator online as per the link above.
You'll get a pension at normal retirement age (age 67 or 68?) based on your career average salary and 5 years' service. A very small pension in other words.
