If you have any questions or concerns, or suggestions for improvements, please contact the Retirement Office.
The Retirement Office has available a chart showing the retirement percentage a member would receive at any given age, with any given years of service. To see the Group One members chart, click here. For Group Two Members chart, click here. For the Group Four members chart, click here.
When using the chart, keep in mind that your retirement benefits depend on a number of factors:
- Length of Creditable Service
- Salary Level (Highest Consecutive Three Year Average)
- Group Classification
Part-Time Public Service
If you are employed on less than a full-time basis, you will earn an amount of service equal to a percentage of the full-time service rate. A worker employed on a half-time basis will receive 50% or 6 months service for each year completed.
Retirement deductions are not withheld from Workers' Compensation payments. However, employees who are injured on the job and collect Worker's Compensation payments for total disability (equal to 60% of your regular pay) will receive creditable service for the period during which they collect payments.
Employees who are ordered to active duty will receive creditable service during their period of actual military service, to a maximum of four years, so long as they return to work within two years of discharge. Active members may also purchase up to 4 years of creditable service for service in the military prior to employment with the City of Cambridge. If you are interested in this benefit, please contact the Retirement Office.
Make-up and Redeposits
If you worked for a City or Town, in a position that did not contribute to the local Retirement System, you may be eligible to buy back this service once you become a member of the system. If you were a member, but withdrew your account after leaving your position, you are eligible to redeposit this money in order to reestablish your former creditable service. For more information on this process, please contact the retirement office.
To figure out your average annual rate of compensation, add your three highest consecutive years compensation and divide by three.
Your group classification will determine the specifics of your benefit rate. Group classification is determined by state law, under M.G.L. Chapter 32 and not the employer or your agency. All questions regarding group classification should be directed to the retirement board office.
