Oregon PERS Calculator: How to Use It
Oregon PERS has layers: OPSRP for members hired since Aug. 29, 2003, Tier One and Tier Two for earlier hires, and the IAP account for everyone. This calculator covers the OPSRP pension.
What this calculator does
It estimates the unreduced OPSRP pension from ORS 238A.125, checks whether your planned age is normal, early or too young, and estimates your first COLA under the blended rule. For early retirement it applies the PERS early retirement factor table effective Jan. 1, 2025 and shows the reduced pension.
What each input means
Member type
General Service earns 1.5% a year. Police & Fire earns 1.8% and has lower retirement ages, but only if your last 60 months of credit are police or fire service.
Service so far and retirement age
The calculator adds a year of service for each year until retirement.
Final average salary
The higher of your 3 highest consecutive calendar years or your last 36 months. Pay above the SB 1049 limit ($245,724 for 2026) is capped.
Service before October 2013
Only used for the COLA. That share of your pension keeps the older COLA (up to 2%). The rest gets 1.25% on the first $60,000.
Understanding the outputs
Normal retirement shows your full pension and first-year COLA. Early retirement shows the reduced pension as the main figure, with the factor used and the unreduced formula amount below it. If you're not vested, or below 55 (50 for Police & Fire), the result says so and shows when the full pension becomes available.

Frequently asked questions
Who is covered by the OPSRP formula?
Members hired on or after Aug. 29, 2003. Earlier hires are in Tier One or Tier Two, which use different formulas.
How does the early retirement reduction work?
OPSRP pays early retirees the actuarial equivalent of the full pension (ORS 238A.185). The calculator multiplies the formula amount by the factor for your age in years and months from the PERS table effective Jan. 1, 2025. The column depends on service at retirement: under 30 years or 30+ for General Service, under 25 or 25+ for Police & Fire. A General Service member retiring at 60 with 20 years gets 0.659 of the formula amount.
What are the unreduced retirement paths?
General Service: 65, or 58 with 30 years. Police & Fire: 55, or 53 with 25 years, if your last 60 months of credit are police or fire service.
How does the OPSRP COLA work?
A blend by service. Service after the 2013 changes gets 1.25% on a yearly pension up to $60,000 and $750 plus 0.15% above that. Service before those changes keeps the CPI-based COLA capped at 2%, per Moro v. State (2015).
What is the IAP and why isn't it in this calculator?
The Individual Account Program is a separate account funded by 6% of your salary. It's paid as a lump sum or installments at retirement and depends on investment returns, so it isn't part of the pension formula.
