Understanding creditable service is essential for maximizing your retirement benefits. Learn how different types of service count toward your pension and what options you have to increase your service credit.
Service Credit Fundamentals
What is Creditable Service?
Creditable service is the total amount of time that counts toward your retirement benefits calculation. It includes periods of employment where you made retirement contributions, plus any additional service you may purchase or transfer from other qualifying employment.
- Determines your years of service multiplier
- Affects your minimum retirement age eligibility
- Impacts your final retirement benefit amount
- Can be increased through service purchases
How Service Credit is Calculated
Service credit is typically calculated in years and months. Full-time employment earns 1 year of service credit per calendar year. Part-time employment is prorated based on your work schedule.
Each year of service credit increases your retirement benefit. The exact impact depends on your retirement group and age at retirement, with multipliers ranging from 2.0% to 2.5% per year of service.
Important Note
Service credit rules can be complex and may vary based on your employment history, retirement group, and when you were hired. Always verify your specific situation with the Massachusetts State Retirement Board (MSRB) for accurate information.
