Educational estimate only, not financial advice. Uses a simplified Missouri PSRS formula and your inputs; your real benefit varies by service, age, salary rules, and the benefit factor that applies.
How the Missouri PSRS formula works
PSRS uses a single benefit factor that steps up with long service. Members who retire with fewer than 32 years of service earn 2.5% per year of credited service. Members who reach 32 or more years earn the higher 2.55% factor on every year of service. The calculator above defaults to 2.5%, which fits most members.
Final average salary is the monthly average of your three highest consecutive years of PSRS-covered salary, which can include employer-paid health, dental, and vision premiums. Most Missouri public school teachers do not pay into Social Security on their PSRS-covered earnings, so your pension is the core of your retirement income.
