Missouri MOSERS Retirement Calculator: How to Use It
Your MOSERS plan depends on when you were first employed. It decides your multiplier, whether you get the Rule of 80 or 90, and whether a temporary benefit bridges you to 62.
What this calculator does
It projects your service to the age you leave state employment, applies your plan's multiplier to your final average pay, and checks the rules for your plan: normal retirement by age, the Rule of 80 or 90, early retirement, or a vested benefit that waits. If you qualify for the temporary benefit, it shows that too.
The result is the Life Income Annuity, before any survivor option, unused sick leave credit or BackDROP election.
What each input means
MOSERS plan
Set by your first employment date in a benefit-eligible position. It changes the multiplier (1.6% or 1.7%), the retirement rules and whether a temporary benefit exists.
Current age and years of credited service
Use your credited service from MOSERS. The calculator adds a year for each year until you leave.
Final average pay
Your highest 36 consecutive months, entered as an annual amount.
Age when you leave state employment
The Rule of 80 and Rule of 90 are measured at termination, so this is the age that counts.
Understanding the outputs
Green means unreduced, or vested with a benefit that starts at normal retirement age. Yellow means early, with the permanent cut. If a temporary benefit applies, the headline number is base plus temporary, and the base alone continues after 62.
A Rule of 90 example
An MSEP 2011 member who started at 22 reaches 55 with 33 years: 88 points, not enough. At 56 with 34 years it's 90. With a $60,000 final average pay that's 1.7% x $5,000 x 34 = $2,890 a month for life, plus 0.8% x $5,000 x 34 = $1,360 a month until 62.

Frequently asked questions
Which plan should I pick?
MSEP if you were first employed before July 1, 2000 and vested. MSEP 2000 if first employed July 1, 2000 through December 31, 2010. MSEP 2011 if first employed on or after January 1, 2011. Your MOSERS account shows your plan.
What is final average pay?
The average of your highest 36 consecutive months of pay. Enter it as a yearly figure; the calculator converts it to monthly.
How is the early reduction figured?
0.5% for each month you're younger than your normal retirement age: 65 (or 60 with 15 years) in MSEP, 62 in MSEP 2000, 67 in MSEP 2011. Thirty months early is a 15% cut.
Why does my benefit drop at 62?
The temporary benefit, paid to MSEP 2000 members under the Rule of 80 and MSEP 2011 members under the Rule of 90, ends at 62 along with any COLAs on it. The base benefit continues for life.
What COLA does the calculator use?
The real COLA is 80% of the CPI increase, 0% to 5%. The calculator illustrates it at 1.5%, the rate MOSERS uses in its handbook examples.
