Why creditable service is important
Creditable service:
- is one of the three factors used to calculate the amount of your retirement benefit (the other two are your age and final salary average); and,
- determines whether you are "vested" for purposes of receiving a retirement benefit.
At the time of your retirement, we will review and verify your creditable service history.
You may earn service credit in two ways: automatically while you are contributing to the MTRS via regular payroll deductions; and, if you have previously rendered eligible service, you may be able to purchase credit for your prior employment.
