Benefit Formula 

If you are a general state employee (including college and university employees), when you apply for retirement, your monthly base benefit* is calculated using a formula, as defined by law, that takes into account the following factors:

  • Final Average Pay (FAP) – The average of your highest 36 consecutive months of compensation
  • Multiplier – The multiplier established by the legislature (1.6% or 0.016 for MSEP; 1.7% or 0.017 for MSEP 2000 and MSEP 2011)
  • Credited Service – Your years and months of credited service earned, purchased, or transferred, and unused sick leave (if applicable)

* Base benefit is the amount before any reductions, taxes, or other deductions.

Examples - Using the multiplier for MSEP 2000 or MSEP 2011 retirees:

$3,000 (FAP)   x   0.017 (Multiplier)   x   15 years (Credited Service)   =   $765 monthly base benefit

$3,500 (FAP)   x   0.017 (Multiplier)   x   17.5 years (Credited Service)   =   $1,041.25 monthly base benefit

$4,000 (FAP)   x   0.017 (Multiplier)   x   30 years (Credited Service)   =   $2,040 monthly base benefit

$_____ (FAP)   x   ____ (Multiplier) x ____ years (Credited Service) = $_______ monthly base benefit
