Missouri PSRS

This page documents how FinZot models the Missouri PSRS defined benefit pension plan.

Employee contributions are the portion of salary that the employee pays into the pension fund.

FieldValue
Contribution Rate14.5% of salary
Tax TreatmentPre-tax (reduces taxable income)

Vesting determines when an employee has earned the right to receive pension benefits. The following formula must evaluate to TRUE for the employee to be vested:

service_credits >= 5

Retirement eligibility determines when an employee can begin receiving pension payouts. The following formula must evaluate to TRUE:

OR(AND(commencement_age >= 55, service_credits >= 5), service_credits >= 25,(commencement_age + service_credits) >= 80)

Formula Variables:

  • service_credits: Years of credited service
  • commencement_age: Age when pension payments commence

The annual pension benefit is calculated as:

Annual Benefit = Final Compensation × Benefit Factor × Service Credits

Final compensation is the salary figure used in the benefit calculation, typically an average of the employee’s highest-earning years.

FieldValue
MethodHighest Consecutive Years
Years Averaged3

The benefit factor is a percentage multiplier that typically varies based on retirement age. Higher ages generally yield higher factors.

Formula Variables:

  • commencement_age: Age when pension payments commence

The COLA formula determines how pension benefits grow over time after retirement to keep pace with inflation.

current_pension_benefit *(1 + CASE
WHEN inflation_rate >= 0.05 THEN 0.05
WHEN inflation_rate >= 0.02 THEN 0.02
ELSE 0.0
END)

Formula Variables:

  • initial_pension_benefit: The annual benefit amount at retirement
  • years_since_retirement: Number of years since retirement began

Pension payouts from this plan are taxable as ordinary income.
