A member may retire with reduced benefits as early as age 55 after completing at least 5 years of Oklahoma service. Reduced benefits are calculated in the same manner as other retirement benefits, but are reduced 6 2/3 percent for each year the member's age is below 62.
Calculating Benefits
For Rule of 80 members, the monthly benefit is determined by multiplying the average salary of the three highest years of contributory service by 2 percent, times years of service, divided by 12. For Rule of 90 members, the monthly benefit will be computed based on an average salary of the five highest consecutive years.
However, in all cases, years of service prior to July 1, 1995 shall be calculated using an average salary no greater than $40,000. In addition, employees of the University of Oklahoma and its constituent agencies, and employees of Oklahoma State University and its constituent agencies, who were employed by these universities prior to July 1, 1995, will have retirement benefits calculated in compliance with 70 O.S. 17-116.2B, and in accordance with annual contributions.
TRS offers members five retirement plans, each providing a life benefit to the member and, after the member's death, either a lump sum payment to the member's designated beneficiary(s), or continued payments to a beneficiary designated at the time the member retires.
