Common questions
How is a PSRS pension calculated?
2.5% × your final average salary × your years of service. Your final average salary is the monthly average of your 3 highest years in a row. In PSRS's example, 28 years and a $4,590 monthly average pay $3,213 a month.
When can I retire from PSRS with full benefits?
At 60 with 5 years, with 30 years at any age, or when your age plus your service adds up to 80 (the Rule of 80).
What are 25-and-Out and age-reduced benefits?
They're PSRS's two kinds of early retirement. Under 55 with 25 to 29-plus years, 25-and-Out uses a smaller factor (2.2% to 2.4%). From 55 to 59 with 5 years, age-reduced benefits multiply the full formula by an age factor (0.6543 at 55).
What is the 2.55% factor?
With 32 or more years, PSRS uses 2.55% instead of 2.5% for all your years.
What is the PLSO?
The Partial Lump Sum Option pays you 12, 24 or 36 times your Single Life benefit as a lump sum, for a smaller check for life. It needs age 63 with 8 years, 33 years, or age plus service of 86.
Is this the official PSRS calculator?
No. This is an unofficial estimate built from the PSRS Member Handbook. It isn't affiliated with PSRS. PSRS's Web Member Services has official estimates, and PSRS decides your benefit.
Compare Missouri with other states
- States where teachers don't get Social Security: Most PSRS members don't pay into Social Security on PSRS pay. It depends on your district and position.
- Teacher DROP plans by state: No. PSRS has no DROP. The Partial Lump Sum Option is the only lump sum at retirement.
- Teacher pension COLAs by state: Not automatic. The Board sets each one from inflation (CPI-U): 0%, 2% or 5% under its policy. The most is 5% a year.
- State taxes on teacher pensions, by state: Missouri taxes it, but its public pension exemption may let you deduct up to 100%, capped at the top Social Security benefit.
- Teacher pension multipliers by state: 2.5% × years × average of your best 3 years in a row. With 32 or more years, 2.55%.
- Teacher retirement age by state: Age 60 with 5 years, 30 years at any age, or the Rule of 80 (age + years = 80).

Some states have a DROP program. The PSRS Member Handbook doesn't describe one. The only lump sum at retirement is the Partial Lump Sum Option (PLSO).
