What is my service retirement benefit?

Eligibility

Your service retirement benefit depends on your final average salary (FAS) and your service credit years at retirement. You are eligible to retire:

“Actuarially reduced” means benefit payments are reduced based on factors provided by the Office of the State Actuary. These factors are based on statistics about life expectancy, and projections about the plan’s investment earnings. An actuarial reduction is necessary when benefits are going to be paid over a longer period of time or to more than one person.

If you meet the plan’s age and service requirements and apply for retirement, the effective date of your retirement is the first day of the calendar month immediately following your separation from LEOFF service. You are separated from service on the date you stop working with a LEOFF employer.

Benefit formula

Your monthly service retirement benefit is calculated using the following formula:

Service credit months ÷ 12 x 2 percent x FAS

Final average salary (FAS) is the monthly average of your 60 consecutive highest-paid service credit months. Your FAS cannot include payments for any type of severance pay, such as lump sum payments for deferred sick leave, vacation or annual leave. There is no limit to the number of service credit years that may be included in your benefit calculation.

EXAMPLE
Retirement at age 53

Suppose you retire at age 53 with 30 years and 2 months (362 months) of service. Your final average salary is $4,000. Your monthly benefit will be $2,413.32.

Here is how it is calculated:

  • 362 months ÷ 12 x 2% x $4,000
  • 362 months ÷ 12 = 30.166 years
  • 30.166 years x 2% = .60333
  • .60333 x $4,000 = $2,413.32

The calculation above is based on the standard benefit. Your benefit will be lower if you designate a survivor to receive benefits upon your death. For more information see benefit options. You can use the online estimator to estimate your benefit.
