How much does a 20 year postal employee retire with?

Question

and does previous military time count?

Answer 1

There is no automatic 20-year retirement from postal service.  It is not like the military in that regard.  

Workers for the postal service have the same retirement system as other government employees.  Some long-term employees are under the old CSRS (Civil Service Retirement System), while most people, including everyone hired in recent years, are under the FERS (Federal Employee Retirement System).  FERS is basically like a 401(K) program:  both you and the government contribute funds that are invested, and you can make withdrawals after you retire.

In order to get a pension, you normally need to work until age 55 (there are exceptions, of course, for disability and certain other "early retirement" situations).  If you start working for the government later in life, you can get a pension with 20 years' service, or even less than that, but it will be greatly reduced.

I hope this helps.  Good luck!!
