More years in the formula
ORS's handbook example: a $35,000 pay average at 1.5%.
Five more years add $218.75 a month, about $43.75 a month for each year.
ORS rounds these to $1,313 and $1,531. Your Retirement Plan (R0611C, May 2017; dated), p. 23
A smaller early cut
If you're a Basic or MIP member under 60 with fewer than 30 years, each month you wait removes 0.5% from the cut. Planning Your Retirement (R0613C, 5/26), p. 19, Early reduced pension; ORS web page: Qualifying for Your Pension, Early Reduced Retirement Provisions ('one-half of 1% for each month ... (6% per year)'); MPSERS annual report FY2025, p. 26; MCL 38.1384(2)
- Retire at 55: $1,679.95 a month (30% cut)
- Retire at 59: $2,255.93 a month (6% cut)
- Retire at 60: $2,399.93 a month (no cut)
A higher pay average
If your newest year is one of your highest, it can raise your final average compensation too. The calculator keeps your average the same, so any raise would add more.
Other things that change with your date
Your retirement date also sets when your first MIP increase arrives, and whether you can still choose the equated plan. If you plan to keep working somewhere after you retire, check the working after retirement rules first.

Questions
How much does one more year add to an MPSERS pension?
Each year of service adds 1.5% of your final average compensation to your yearly pension (1.25% for some Basic and MIP service after 2013). With a $35,000 average, that's $525 a year, or about $44 a month, for life.
Does waiting also shrink the early-retirement cut?
Yes, for Basic and MIP members under 60 with fewer than 30 years: each month you wait removes 0.5% from the cut.
Should a deferred member wait past 60 to apply?
No. A deferred pension isn't higher if you wait, and you can lose payments. Apply before your 60th birthday.
