Massachusetts SERS Pension Calculator

Massachusetts State Employee Retirement System Pension Benefit Calculator, Before and After April 2, 2012


This free, online Massachusetts State Employee Retirement System calculator gives you an estimate of your MSERS pension retirement benefits (including interactions of inflation and your COLA) based on the information you input about your salary, years of service, and retirement age and date. It works for pre-April 2, 2012 and on or after April 2, 2012. It takes into account whether you are a  a military veteran and it includes calculations for scenarios with and without additional purchased service. This is the only SERS calculator available that shows you the effects of your MSERS cost-of-living-adjustments (COLA) and inflation on your annual pension benefits over time. It works for Group 1, Group 2, and Group 4.  A unique SERS Group 3 calculator is available here: MA State Police Group 3 online calculator.


The Massachusetts State Retirement Board emphasizes that the formulas used in calculators–even for their very own calculator–give approximations or estimations of retirement benefits. Actual retirement benefits will be determined by MSRB at the time of retirement. To see how marital property is divided in divorce, see this page.

You may find this calculator easier to use than other SERS calculators because this calculator allows you to see, side-by-side, what your retirement benefits would be with and without purchased service.


How Your COLA and Inflation Will Affect Your Annual Benefit Over Time


You may find this calculator valuable for financial planning because it includes calculations showing the value of your projected SERS pension in today’s dollars for each year until you reach age 100. The SERS COLA–3% of the first $13,000–only protects the first $13,000 of your pension from inflation each year. The rest of your pension will lose value quickly because of inflation.


Take the example of an MTRS 49-year-old teacher in 2019 who projects retiring at age 60 with 25 years of service and a high 3-year salary average of $85,000. The Option A annual pension amount will be $42,500. By age 65, the face value of the annual payment will grow slightly, through the COLA, to $43,865. In today’s (2019) dollars, however, that annual payment will only be worth $27,206 at age 65. At age 75, the pension will only be worth $22,050 in 2019 dollars; at age 85, $17, 753; and at age 90, $15,895. You can see all the figures from this COLA-inflation example here.


You can do your own calculations below and download your own .pdf report showing the year-by-year effects of COLA and inflation on your future annual pension benefits. You can change the projected inflation rate, if you like, and you can choose what annual pension benefit (i.e., Option A, B, or C) you would like it to calculate for COLA and inflation.
