I have been employed by the Postal Service for 22 years now, started out saving around 10%, then with each pay increase, I would step it up another percent until reaching the max. I have no military time and my wife is not employed, so she has only my retirement funds.
I now have a balance of about $365,000 with about eight years to go before being a former postal employee.
I mostly stay invested in the C and S funds and have found I lose more by getting out into the G fund than I do by staying in the C & S funds, always bad timing.
Hope the Trump market keeps going strong!
