Employee Contributions

Field	Value
Contribution Rate	7% of salary
Tax Treatment	Pre-tax (reduces taxable income)

Vesting & Retirement Eligibility

Vesting

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:

OR(service_credits >= 10, AND(separation_age >= 60, service_credits >= 5))

Retirement Eligibility

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

OR(service_credits >= 30, AND(commencement_age_months > 720, service_credits >= 10), AND(separation_age >= 60, service_credits >= 5), AND(separation_age >= 55, service_credits >= 15))

Formula Variables:

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

Benefit Calculation

The annual pension benefit is calculated as:

Annual Benefit = Final Compensation × Benefit Factor × Service Credits

Final Compensation

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

Field	Value
Method	Highest Consecutive Years
Years Averaged	3

Benefit Factor

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

CASE
  WHEN commencement_age >= 60 OR service_credits >= 30 THEN 0.015
  ELSE 0.015 * MAX(0.0, 1 - 0.005 *(720 - MAX(commencement_age * 12, commencement_age_months - 1)))
END

Formula Variables:

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

Cost-of-Living Adjustment (COLA)

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

initial_pension_benefit *(1 + 0.03 * MAX(0, years_since_retirement - IF(commencement_month >= 11, 1, 0)))

Formula Variables:

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

Tax Treatment

Pension payouts from this plan are taxable as ordinary income.

Social Security Coverage

Michigan MPSERS (MIP 7%) 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.
