Kansas KPERS 1

This page documents how FinZot models the Kansas KPERS 1 defined benefit pension plan.

Who this plan covers: General and education members of Kansas Public Employees Retirement System, before July 1, 2009: employed in a KPERS-covered position before July 1, 2009 (state, school and local groups).

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

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:

ROUND(service_credits) >= 5 OR(separation_age >= 65 AND ROUND(service_credits) >= 1)

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

OR(AND(commencement_age >= 65, ROUND(service_credits) >= 1), AND(commencement_age >= 55, ROUND(service_credits) >= 10), commencement_age + ROUND(service_credits) >= 85)

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.

Years Averaged3

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

WHEN OR(AND(commencement_age >= 65, ROUND(service_credits) >= 1), AND(commencement_age >= 62, ROUND(service_credits) >= 10), commencement_age + ROUND(service_credits) >= 85) THEN 1.0
WHEN AND(commencement_age >= 55, ROUND(service_credits) >= 10) THEN MAX(0.0, 1 - 0.002 * MIN(24, MAX(0, 744 - commencement_age_months + IF(birth_day_of_month >= 17, 1, 0))) - 0.006 * MAX(0, 720 - commencement_age_months + IF(birth_day_of_month >= 17, 1, 0)))
ELSE 0.0
END)

Formula Variables:

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

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

current_pension_benefit

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.

Kansas KPERS 1 members generally pay into Social Security alongside the pension, so a job with this plan is treated as covered and earns Social Security credits normally.
