Updated October 30, 2026. Quick answer: In the Michigan Public School Employees’ Retirement System (MPSERS), Pension Plus and Pension Plus 2 members may retire at age 60 with 10 or more years of credited service, and they are not eligible for early retirement. Legacy Basic Plan members may retire at 55 with 30 years or at 60 with 10 years. Basic and MIP members with at least 15 but fewer than 30 years of credited service may also take an early permanently reduced pension after age 55, reduced 0.5% for each month before age 60.
Pension Plus and Pension Plus 2
“A Pension Plus 2 member may retire at age 60 with 10 or more years of credited service.” “A Pension Plus member may retire at age 60 with 10 or more years of credited service.” “Pension Plus and Pension Plus 2 members are not eligible for early retirements.”
Basic Plan and MIP
“A Basic Plan member may retire at: • age 55 with 30 or more years of credited service; or • age 60 with 10 or more years of credited service”. “A MIP member who became a member of MPSERS prior to July 1, 2010 may retire at: • age 46 with 30 or more years of credited service; or • age 60 with 10 or more years of credited service”.
Early retirement for Basic and MIP
“A MIP or Basic member may retire with an early permanently reduced pension: • after completing at least 15 but less than 30 years of credited service; and • after attaining age 55”. “The early pension is computed in the same manner as a regular pension, but is permanently reduced 0.5% for each full and partial month between the pension effective date and the date the member will attain age 60.”
Vesting
“You’re vested when you have the equivalent of 10 years of full-time public school employment.” “If a member terminates employment before attaining the age qualification, but after accruing 10 or more years of credited service, the member becomes a deferred member and is eligible for a pension at the time the age qualification is attained.”
What the pension is based on
“Annual Amount, Pension Plus and Pension Plus 2 Plans-Credited service x 1.5 x FAC.” “Final Average Compensation-Average of highest 60 consecutive months (36 months for MIP members).”
A worked example with invented numbers
Take an invented Pension Plus member who retires at 60 with 30 years of credited service. That is 30 years at 1.5%, or 45% (computed) of a final average salary of $60,000 (invented, for the computation), which comes to $27,000 a year (computed).
Now take an invented Basic Plan member who takes the early pension at age 55, 60 months before age 60. The reduction is 60 months before age 60 at 0.5% each, which is 30% (computed).
What the documents do not say
The newest document read that states the Pension Plus 2 rule in prose is the fiscal year 2022 annual comprehensive financial report; the Office of Retirement Services booklet read (2025 edition) covers only the Basic and MIP plans, so the current Pension Plus 2 rule is not confirmed in a 2025 or 2026 document. The no-early-retirement statement and the 1.5 formula come from the report’s plan summary list. The regular retirement age for Pension Plus 2 can rise by whole years under Section 81c(5) of Public Act 300, and the documents do not say whether it has changed since fiscal 2022. The statute (MCL 38.1361 and following) was not read, so the hire dates that separate Pension Plus from Pension Plus 2 are not stated here.
Common mistakes
- Looking for an early retirement option under Pension Plus. The fiscal 2022 annual report says those members are not eligible for early retirement.
- Using the Basic age of 55 with 30 years for a Pension Plus member.
- Treating the retirement age as fixed forever. The same report notes that the Pension Plus 2 retirement age can be raised in whole years under the plan’s provisions.
