Retirement Eligibility  

There are three different types of Service Retirement in ERS:

Normal Retirement

  • At least age 60 and a minimum of 10 years of creditable service (for certain Law Enforcement positions, age 55 and 10 years)
  • At least 30 years of creditable service 
  • For certain Law Enforcement positions, at least age 55 and a minimum of 10 years of creditable service

Early Retirement

  • Under age 60
  • At least 25 years of creditable service but not yet 30 years of service
  • Retiree benefit is reduced at a rate of 7% for every year the retiree is under age 60 or every year the retiree has less than 30 years; ERS will use the lesser reduction to calculate the benefit.

Terminated Vested Retirement

A member terminating after attaining at least 10 years of service but prior to age 60, will be able to start drawing retirement benefits at age 60. A member may contact ERS within 90 days of his/her 60th birthday for more details.

Retirement Amount

Retirement Benefit Factor 

The ERS Old Plan Benefit Factor is 2% between 10 years of service and 28 years of service. After the 28th year of service, the factor increases incrementally each year, eventually maxing out at 2.20% at the 35th year of service

Calculation Formula:

To calculate the Maximum Plan Benefit for a normal retirement, ERS Old Plan uses the following formula

Formula Salary x
Benefit Formula Factor x
Creditable Service =
Maximum Plan Benefit

Please see the ERS Handbook for calculation examples.
