Re: might be a dumb question
Your pension will have no effect on the amount that you receive in Soc. Sec. (Earned income is the criterea that is used for adjustment).
The only effect that your pension, or any other passive earnings have of Soc. Sec. is that it will be a factor when computing how much your soc. sec. will be taxed.
If you want an explanation of the formula for that, Ted, Cutthroat, TH, or some of the other statiticians on this board will help you. (You guys thought you were retired, didn't you?)
