Updated October 30, 2026. Quick answer: Oregon PERS sets normal retirement age at 58 for Tier One members (membership before January 1, 1996) and 60 for Tier Two members (membership on or after that date). In the OPSRP pension program, the normal retirement age is the earlier of 65, or 58 with 30 years or more of retirement credit (the statute sets separate ages for police officers and firefighters). Early retirement is available from age 55 with an actuarially reduced benefit. A Tier One or Tier Two member is vested after 600 hours of service in each of five calendar years, or regardless of years of service if active on or after reaching normal retirement age. The statute also has a separate 30-year service route that this page does not summarize.
Tier One and Tier Two normal retirement age
ORS 238.005 sets the age by when you joined. Membership before January 1, 1996 (Tier One): “58 years of age if the employee retires at that age as other than a police officer or firefighter”. Membership on or after January 1, 1996 (Tier Two): “60 years of age if the employee retires at that age as other than a police officer or firefighter”. For police officers and firefighters the statute sets: “55 years of age if the employee retires at that age as a police officer or firefighter”.
Early retirement and the reduction
“Except as otherwise provided in this section, a member of the Public Employees Retirement System who attains the age of 55 shall be retired upon written application by the member to the Public Employees Retirement Board on a reduced service retirement allowance, that is the actuarial equivalent of the service retirement allowance”. Under the Full Formula method, the PERS page’s own example: “with less than 30 years of service and retire three years early (at 55 if you are Tier One; at 57 if you are Tier Two), your entire benefit will be reduced by approximately 23 percent”.
The OPSRP pension program
ORS 238A sets the normal age: “normal retirement age for a member of the pension program is the earlier of: (a) 65 years of age; or (b) 58 years of age if the member has 30 years or more of retirement credit”. “Except as provided in this section, earliest retirement age for a member of the pension program is 55 years of age.” “A member of the pension program who is vested may retire with a reduced pension that is the actuarial equivalent of the pension provided for in ORS 238A.180 at any time on or after the member’s earliest retirement date”.
Vesting
“You are vested in your Tier One or Tier Two account on the earliest date in which you complete at least 600 hours of service in each of five calendar years”. The PERS page adds: “If you are an active member any time on or after reaching normal retirement age, you become a vested member regardless of years of service.”
What the pension is based on
Tier One and Tier Two, general service: “1.67 percent of final average salary multiplied by the number of years of membership in the system as other than a police officer or firefighter before the effective date of retirement”. The salary average: “The average salary per calendar year paid by one or more participating public employers to an employee who is an active member of the system in three of the calendar years of membership before the effective date of retirement”. OPSRP: “1.5 percent of final average salary multiplied by the number of years of retirement credit attributable to service as other than a police officer or firefighter”.
A worked example with invented numbers
Take an invented Tier One or Tier Two general-service member with 25 years of membership who retires at the normal age. That is 25 years at 1.67%, or 41.75% (computed) of a final average salary of $70,000 (invented, for the computation), which comes to $29,225 a year (computed).
Now take an invented OPSRP member with 25 years of retirement credit who retires at the normal age. That is 25 years at 1.5%, or 37.5% (computed) of a final average salary of $70,000 (invented, for the computation), which comes to $26,250 a year (computed).
What the documents do not say
The PERS eligibility page prints its age and service tables as table cells, so the ages here come from the prose of ORS chapters 238 and 238A. The actuarial equivalency factors are published in separate tables that were not read, and the sources do not give the hire date that places a worker in OPSRP rather than Tier Two. The statute’s separate 30-year service provision, the Money Match and Formula Plus Annuity calculations, police and firefighter multipliers, judges and legislators are not covered. The 1.67 percent figure is the Full Formula multiplier for general service.
Common mistakes
- Using age 58 or 60 for an OPSRP member. The OPSRP pension program’s normal age is 65, or 58 with 30 years of retirement credit.
- Assuming 600 hours in one year vests you. The Tier One and Tier Two rule needs 600 hours in each of five calendar years.
- Taking the 23 percent reduction as a fixed number. The PERS page gives it as the Full Formula example of retiring three years early with less than 30 years.
