The formula
Every MPSERS pension plan starts from the same line in the statute, MCL 38.1384(1): years of credited service times 1.5% of final average compensation. What changes between plans is the FAC window, who gets 1.25% instead of 1.5%, and when you can collect.
Annual pension = Years of Service x 1.5% x FAC
FAC is your highest 36 consecutive months of pay if you're in MIP, and your highest 60 consecutive months if you're in Pension Plus or Pension Plus 2 (MCL 38.1304(12)). A Pension Plus 2 member with 25 years and a $60,000 FAC gets $22,500 a year, or $1,875 a month.
The 2012 reform (PA 300 of 2012) split MIP. Members who didn't move to the 7% contribution rate kept 1.5% on service up to their transition date, around February 1, 2013, and earn 1.25% on everything after. MIP 7% members get 1.5% on all service, unless they chose an attainment date, in which case service after 30 years earns 1.25%. If you're not sure which one you picked, miAccount shows it.
Which plan you're in
- MIP: first worked before July 1, 2010 (MIP Fixed, Graded and Plus).
- Pension Plus: first became a member July 1, 2010 through January 31, 2018. From September 4, 2012, new hires could opt out to the DC plan.
- Pension Plus 2: first worked on or after February 1, 2018 and elected it. Starting with hires on July 1, 2024, it's the default if you don't choose within 75 days.
Hires from February 1, 2018 to June 30, 2024 who made no election landed in the Defined Contribution plan, which has no pension. Basic Plan members (hired before 1990 who never joined MIP) aren't covered by this calculator.
When you can retire
Pension Plus and Pension Plus 2 have one door: age 60 with 10 years of service (MCL 38.1381c). There's no 30-years-at-any-age route and no reduced early pension. A Pension Plus member who starts at 22 and has 32 years at 54 still waits until 60 to collect. Leave with 10 years at any age and the pension starts at 60.
Pension Plus 2's age of 60 isn't fixed for life. The statute raises it in whole years if an ORS mortality study shows a 65-year-old living a year or more longer than the 2012-2017 study did, unless the plan is over 100% funded. Anyone within 5 years of the age when it changes is exempt. Pension Plus is locked at 60.
MIP has more options. You can retire at any age with 30 years (46 if you bought universal buy-in service), at 60 with 10 years, or at 60 with 5 years if you earned service in each of the 5 school fiscal years right before you retire. With 15 to 29 years you can go as early as 55 with a reduction of 1/2 of 1% per month before 60. Retire at 55 and the cut is 30%, permanently. You have to be working when you apply. If you quit first, you're a deferred member and wait for 60.
Pension Plus and Plus 2 also have a DC account
Both hybrid plans pair the pension with a 401(k)-style account at Voya. You put in 2% by default and your employer matches 50% of what you contribute, up to 1% of pay. You can lower your share to 0%. The balance depends on contributions and returns, so it's not in this calculator. Check it on your Voya account and add it to the pension figure.
Post-retirement increases
MIP retirees get a raise every October once they've been retired a full year. It's 3% of the starting pension, added again each year without compounding. ORS's own example: Molly retires December 1, 2025 at $1,200 a month and gets $1,236 in October 2027, $1,272 the next October, and $1,308 the October after that.
Pension Plus and Pension Plus 2 have no post-retirement increase. The House Fiscal Agency lists “No Cost of Living increases” for both hybrid plans. The pension you retire with is the pension you keep.

Frequently asked questions
How is a Michigan MPSERS pension calculated?
Years of service x 1.5% x final average compensation (FAC). MIP uses a 36-month FAC; Pension Plus and Pension Plus 2 use 60 months. Pension Plus 2 with 25 years and a $60,000 FAC: 0.015 x 25 x $60,000 = $22,500 a year. MIP members who kept their old contribution rate in 2012 earn 1.25% on service after their February 2013 transition date, and MIP 7% members who picked an attainment date earn 1.25% after 30 years.
When can I retire under Pension Plus or Pension Plus 2?
At age 60 with at least 10 years of service (MCL 38.1381c). There is no early retirement and no 30-year option in either plan. If you leave earlier with 10 years, your pension starts at 60. The Pension Plus 2 age can rise if an ORS mortality study shows longer life expectancy, though members within 5 years of the age are exempt.
When can I retire under MIP?
At any age with 30 years (age 46 if you bought universal buy-in service), at 60 with 10 years, or at 60 with 5 years if you earned service in each of the 5 school fiscal years before retiring. With 15 to 29 years you can take an early reduced pension from 55, cut 1/2 of 1% for each month before 60 (6% a year). You must still be working to use the early reduced option.
Which plan am I in?
MIP covers members who first worked before July 1, 2010. Pension Plus covers members who first became members from July 1, 2010 through January 31, 2018. Pension Plus 2 covers members who first worked on or after February 1, 2018 and elected it (or, from July 1, 2024, made no election). Your miAccount shows your plan.
Does Michigan MPSERS have a COLA?
MIP retirees get 3% of their initial pension added every October once they have been retired a full year. It does not compound: ORS's example is $1,200 a month becoming $1,236, then $1,272, then $1,308. Pension Plus and Pension Plus 2 have no post-retirement increase.
