How to work out your Gold State Super benefit

You can use our Gold State Super calculator below to work out how much you could have in your Gold State Super account by the time you retire.

By using the calculator, you could explore your options and get answers to questions you might have, such as:

  • ‘What if I work another four years?’
  • ‘How will my balance change if I get a pay rise?’
  • ‘How much will I have if I start working part time?’

Your latest member statement has all the information you need to use the calculator. You can log into or register for Member Online for a copy of your latest statement.

Please note, this calculator is intended as a guide only. It does not take into account ‘other benefit components’ that may form part of your benefit, such as transferred service from the WA Public Sector Pension Scheme or the Non-contributory Service Scheme. For a full benefit estimate, contact your Member Services Centre on 13 43 72.

Please enter your Completed Months of Service as a whole number with no decimal points.
You will find your Completed Months of Service on your statement in the 'membership summary' section. It is listed as your contributory service membership.
Note the last date of your statement period and add the number of months you have worked since then, or the completed months you will have worked for the scenario you are looking at. If you are including part-time service, you’ll need to adjust your Service Multiple. For example, working at 75% of the full-time equivalent means you’ll add another Completed Month of Service every 40.5 days, instead of every 30.4 days if you were working full time.
Please enter an Average Contribution Rate of up to 5% with no more than one decimal point.
You will find your Average Contribution Rate on your statement in the 'contribution overview' section. If your rate is currently below 5%, you can increase your contributions to bring your percentage closer to your maximum contribution rate. For more information, read the Gold State Super essentials brochure.
Please enter your Final Remuneration as a whole number with no decimal points.
You will find your Final Remuneration at the top of your statement in the 'account summary' section. If you think your Final Remuneration will be higher for the scenario you are looking at, simply enter that amount instead.

How we work out your Gold State Super

We use a formula to work out your final super benefit. This generally happens when you retire, leave the WA public sector or you pass away.

The formula takes into account:

  • Your Completed Months of Service - the number of completed months you’ve contributed to your account while working in the WA public sector
  • Your Average Contribution Rate - the average percentage of your salary you’ve paid into your account over your membership
  • Your Final Remuneration - your average salary based on three dates during the last two years of your membership

Once we have this information, we can work out your benefit in three steps:

1. We determine your ‘Selection Date’

Your selection date is either the 1st or 16th day of the month, two months before the month of your birthday:

  • If your birthday falls on one of the first 15 days of the month, your selection date is the 1st
  • If your birthday falls in the second half of the month, your selection date is the 16th

For example, if your birthday is on 25 August, then your selection date will be 16 June. If your birthday is 8 August, your selection date will be 1 June instead.

2. We calculate your Final Remuneration

Your Final Remuneration is your average salary based on:

  • The date you stop working
  • Your Selection Dates for the previous two years

We multiply your fortnightly remuneration2 on these dates by the number of days between each date and then divide this by 14 (the number of days in a fortnight).

3. We calculate your Final Benefit

We use your Completed Months of Service and Average Contribution Rate to work out your ‘Service Multiple’:

Service multiple = Completed Months of Service/12 x 20% x Average Contribution Rate/5

Finally, we multiply your Service Multiple by your Final Remuneration to work out your benefit:

Service Multiple x Final Remuneration = Final Benefit

For examples of how we work out benefits, see our Gold State Super essentials brochure.

Changes to your salary or service could affect your benefit

You might not know it but any changes to your salary or the amount of time you work in the WA public sector could have a big impact on your benefit.

For example, if you accept a lower-paid position with your current employer as a result of ill health or changes in your workplace, your benefit could be reduced. However, you can protect your benefit if you’re eligible for salary maintenance.

For more information, read the FAQs below or call your Member Services Centre on 13 43 72.

Call us before changing your contributions

Your benefit could also be affected if you change the amount you contribute to your account each fortnight.

You may even choose to have your contributions paid into another super account. If you do withdraw from Gold State Super, you won’t be able to reopen your membership or contribute to your account in future.

Before you decide to make any changes, it’s worth calling your Member Services Centre on 13 43 72 and asking for a benefit estimate.

1 If you stop working in the WA public sector or reduce your work hours to less than one hour a week, you will no longer be an active Gold State Super member. However, if you re-join the WA public sector or increase your work hours within 12 months, you may apply to continue your membership.
2 Your Final Remuneration is calculated based on your equivalent full-time salary, even if you are working part-time.
