Case Study: PSS
Contribution rate increase and ABM
Faith’s story
Faith is 55 years old and a contributing member of PSS.
As a Research Officer with the Department of Veterans’ Affairs, Faith helps people access their family’s military service history. She’s been thinking of retiring in 5 years to write a book that will bring together some of the stories she’s discovered when researching Indigenous service records.
Faith would like to make sure she has a comfortable retirement income so she can focus on writing. She’d also like enough money to visit the remote communities that were home to the Indigenous veterans of her novel.
With only 5 years until she retires, Faith is concerned it may be too late to make any difference to her retirement options.
She’s contacted her adviser because she wants to know if adding extra to her super each pay would mean a better final benefit when she retires.
Faith meets with her adviser
Faith has been contributing at a rate of 5% since joining PSS 20 years ago. She tells her adviser that she is thinking of increasing her contributions to 10% for the next five years, if that gives her a higher final benefit.
Faith’s adviser lets her know that any increase in contributions will positively affect her final benefit amount, which is calculated using the formula Final Average Salary (FAS) x Accrued Benefit Multiple (ABM). As the ABM increases in line with increases to contribution rates, a higher ABM will give Faith a higher final benefit amount.

“I’ll be retiring in a few years to write my book and travel a little. Is it too late for me to start adding extra to my super each pay?” —Faith |

How contribution rates affect annual ABM accruals
The ABM is based on Faith’s length of employment and all contributions made to her PSS account. The annual ABM accrual will increase if Faith increases her contribution rate. This directly affects her final benefit amount calculation: FAS x ABM.
The 10 year rule
As Faith has completed the equivalent of 10 years’ cumulative employment, she has met the 10 year rule*.
This means that if she increases her contribution rate to 10%, her annual ABM accrual for the years she contributes 10% will be 0.31, a higher rate than the 0.26 that would have applied if she had not met the 10 year rule. See the table for how contribution rates affect annual ABM accruals.
Even if Faith had not met the 10 year rule, her ABM would still be higher if she increased her contributions from 5% to 10%, her annual ABM accrual would go from 0.21 to 0.26.
*The 10 year rule refers to members who have contributed to PSS for 260 public service pay days or contribution due days (CDDs)—the equivalent of 10 years’ cumulative employment. After the first 260 CDDs, if their contribution rate is more than 5%, their ABM accrues at a higher rate than it would have in the first 260 CDDs. See PSS Maximum Benefit Limit for conditions.
Contribution rates and ABM accrual
Rate | Annual ABM accrual | Annual ABM accrual (ten year satisfied) |
---|---|---|
0% | 0.11 | 0.11 |
2% | 0.15 | 0.15 |
4% | 0.17 | 0.17 |
5% | 0.19 | 0.19 |
6% | 0.22 | 0.23 |
7% | 0.24 | 0.27 |
8% | 0.24 | 0.27 |
9% | 0.25 | 0.29 |
10% | 0.26 | 0.31 |
Faith’s total final benefit comparison
Faith’s final benefit amount is calculated using the formula Final Average Salary (FAS) x Accrued Benefit Multiple (ABM).
Generally, FAS is the average of a member’s last 3 birthday super salaries calculated as at his or her last day of membership. A member’s birthday super salary is typically the full-time equivalent of their annual rate of pay, including any recognised allowances.
Faith’s 3 projected birthday super salaries when she retires in 5 years will be $98,000; $100,000 and $102,000. Her FAS will be the average of these: $100,000.
To see the difference an increase in contributions would make, Faith’s adviser only needs to compare Faith’s contribution rates for the next 5 years until she retires at age 60.
-
Contribution rate of 5% ($105,000 final benefit)
If Faith continues contributing at 5%, the annual ABM accrual will be 0.21. This gives her an ABM of 1.05 (0.21 x 5 years of service).
Faith’s projected final benefit for the 5 years will be $105,000 (FAS of $100,000 x ABM of 1.05).
-
Contribution rate of 10% ($155,000 final benefit)
If Faith increases her contribution rate to 10%, the annual ABM accrual will be 0.31, taking into account that she has met the 10 year rule. This gives her an ABM of 1.55 (0.31 x 5 years of service).
Faith’s projected final benefit for the 5 years will be $155,000 (FAS of $100,000 x ABM of 1.55).
Increasing her contribution rate to 10% for the next 5 years means Faith will have an extra $50,000 available to her on retirement. Faith can now increase her contribution rate knowing that it will have a positive effect on her retirement benefit.
Contribution resolution for Faith
After meeting with her adviser, Faith is confident to go ahead and increase her contribution rate. She can do this by submitting their election to change contribution rate to her employer.
✓ She knows how her contribution rate is taken into account when calculating her final benefit amount.
✓ She understands that over the next 5 years, her defined benefit would increase by $50,000, reflecting the higher annual ABM accrual associated with a 10% contribution rate.
✓ She knows that by having a higher final benefit amount on retirement, her pension and lump sum options will better support her goals of focusing on her writing and travel research.
