Active Members

The State-provided pension portion is determined by the following formula:

Average Annual Compensation X 1.1% [0.011] X Years of Service

A member retiring early receives a percentage of the State's pension portion, according to the following chart:

Age Percent of Benefit
Age Percent of Benefit
59 89%
54 64%
58 84%
53 59%
57 79%
52 54%
56 74%
51 49%
55 69%
50 44%

Factors

The amount of retirement benefit is based on several factors:

  • Average Annual Compensation: The average of the five highest years of annual compensation earned during a member's career plus a maximum of $2,000 of any amount received in contemplation of retirement.
  • Benefit Multiplier: This figure is established by law (currently 1.1%)
  • Years of Service: Number of creditable years served by a member
  • Member's Age at Retirement: Early retirement will cause a reduction in the State pension portion (see above)
  • Retirement Option Selected
  • Annuity Savings Account balance
