About the Tool

The Massachusetts State Employees’ Retirement System (MSERS) provides a defined benefit pension to public employees across the Commonwealth. Your final retirement allowance is determined by a formula that considers your age, years of service, group classification, and an average of your highest salaries. This calculator is designed to provide a reliable estimate based on these factors to assist you in your retirement planning.

Key Features of Our Tool

  • Official Formula: Utilizes the MSERS formula: Age Factor x Years of Service x Average Salary.
  • Pension Reform Aware: Automatically adjusts the rules and age factors based on whether your membership began before or after the April 2, 2012 reform.
  • Group Classifications: Calculates benefits for Group 1, Group 2, and Group 4 members, applying the correct age factor for each.
  • 80% Cap: Automatically applies the rule that a retirement allowance cannot exceed 80% of your final average salary.

Frequently Asked Questions

1. What is my Group Classification?

Most state and municipal employees are in Group 1. Group 2 includes employees with hazardous duties like mental health hospital attendants. Group 4 is for police officers, firefighters, and other public safety officials. Your HR department can confirm your group.

2. Why is the April 2, 2012 date so important?

Pension reforms enacted in 2011 changed the rules for new members. Those hired on or after April 2, 2012, have a higher minimum retirement age, a 5-year salary average instead of 3, and a different age factor table.

3. What is the 80% limit?

Massachusetts law states that a member’s retirement allowance cannot be more than 80% of their final average salary. This calculator automatically caps your result at this limit if your calculated benefit exceeds it.

4. Is this an official estimate?

No, this is an unofficial planning tool. For a formal, binding estimate, you must contact the Massachusetts State Retirement Board (MSRB) or your local retirement board directly.
