First: when is it "normal" retirement?
The rules depend on your membership class:
- Class T-C and T-D: full (unreduced) retirement at age 62, at age 60 with 30 years of service, or with 35 years of service at any age.Handbook p. 19, Normal Retirement
- Class T-E and T-F: full retirement at age 65 with at least 3 years of service, or when your age plus service totals 92 and you have at least 35 years (the Rule of 92). PSERS's example: age 57 with 35 years.Handbook p. 19; PSERS web page Leaving Employment (Nov. 2026)
- Class T-G: full retirement at age 67 with at least 3 years, or age plus service totaling 97 with at least 35 years (the Rule of 97). PSERS's example: age 62 with 35 years.Handbook p. 19; PSERS web page Leaving Employment (Nov. 2026)
- Class T-H: full retirement at age 67 with at least 3 years of service. There is no Rule of 97 for T-H.Handbook p. 19
The handbook says T-C and T-D members reach normal retirement at 'age 62'. PSERS's web page says 'age 62 with 1 year of service'.
We require 1 year of service at 62.
Handbook p. 19; PSERS web page Leaving EmploymentPSERS doesn't say whether the Rule of 92 (or 97) counts your age in whole years or in years and months.
We count years and months, with service to the fraction of a year.
Handbook p. 19, Normal RetirementSpecial early retirement: 55/25
A '55/25' retirement (T-C, T-D, T-E, T-F, T-H; '57/25' for T-G) is reduced by one quarter of one percent per month for each month you are under normal retirement requirements. Handbook p. 19, Special Early Retirement; PSERS web page Leaving Employment (fetched 2026-11-11)
The 55/25 cut by class
Someone retiring exactly at the 55/25 minimum (57/25 in T-G) with 25 years, still working toward normal retirement:
| Class | Retires at | Months short | Cut | Normal retirement would have been |
|---|---|---|---|---|
| T-C | 55 with 25 years | 60 | 15% | July 2031 (age 60) |
| T-D | 55 with 25 years | 60 | 15% | July 2031 (age 60) |
| T-E | 55 with 25 years | 120 | 30% | July 2036 (age 65) |
| T-F | 55 with 25 years | 120 | 30% | July 2036 (age 65) |
| T-G | 57 with 25 years | 120 | 30% | July 2036 (age 67) |
| T-H | 55 with 25 years | 144 | 36% | July 2038 (age 67) |
Months are counted until you'd meet a normal retirement rule if you kept working. That's our reading; see "Check with PSERS" below. Handbook p. 19, Special Early Retirement; PSERS web page Leaving Employment (fetched 2026-11-11)
For a 55/25 retirement (57/25 in T-G), PSERS cuts the benefit 1/4% for each month you are short of normal retirement. Its booklets don't say exactly how those months are counted.
We count the months until you would have met a normal retirement rule if you had kept working, and count a part month as a whole month. This matches PSERS's own sample retiree (60 months, 15%).
Handbook p. 19, Special Early RetirementOther early retirement
Other early retirements: 'The normal retirement benefit is reduced by an early retirement factor so that the present value of the account is actuarially equivalent. The reduction correlates to how far away the member is from superannuation age.' PSERS does not publish the factors in the downloaded sources. Handbook p. 19, Early Retirement
Ordinary early retirement (not 55/25) is reduced by actuarial factors PSERS doesn't publish.
We show the unreduced amount as an upper limit and don't guess the cut. Ask PSERS for an estimate.
Handbook p. 19, Early Retirement- You can retire early with a reduced benefit once you have 5 years of service (T-C, T-D) or 10 years (T-E, T-F, and the DB part of T-G and T-H). There is no minimum age.Handbook p. 19, Early Retirement
- For T-G and T-H, retiring early between 62 and 67, or before 62 with 25 years, uses the same factors as the older classes. Retiring before 62 with less than 25 years adds a second, different reduction from your age to 62.Handbook p. 19, Early Retirement
- You can choose a later retirement date than the day after you leave, for example to reach age 55 for a 55/25 retirement.Exit Counseling 2025-2026, PDF p. 55
Your retirement date is the day after you terminate all public school employment if PSERS receives your Application for Retirement within 90 days of termination; otherwise it is the date PSERS receives the application unless you chose a later date. You may delay the date to qualify for age-based benefits such as 55/25. Handbook p. 21, Applying for Normal and Early Retirement; Exit Counseling 2025-26, PDF p. 55
Questions
How much does PSERS reduce a 55/25 retirement?
A '55/25' retirement (T-C, T-D, T-E, T-F, T-H; '57/25' for T-G) is reduced by one quarter of one percent per month for each month you are under normal retirement requirements.
How much does PSERS reduce other early retirements?
Other early retirements: 'The normal retirement benefit is reduced by an early retirement factor so that the present value of the account is actuarially equivalent. The reduction correlates to how far away the member is from superannuation age.' PSERS does not publish the factors in the downloaded sources. So our calculator shows the unreduced amount as an upper limit for these, and you should ask PSERS for an estimate.
What is the earliest I can retire from PSERS?
You can retire early with a reduced benefit once you have 5 years of service (T-C, T-D) or 10 years (T-E, T-F, and the DB part of T-G and T-H). There is no minimum age.
