I'm curious about what folks think a comfortable inflation proof pre tax retirement income would be for them, in today's dollars. I have my own ideas about what is right for me, but choose not to poison the well by posting that first. I will say that for me to get it right and be certain it's right, I plan to add social security to my retirement mix, so my last day at work will be April 3, 2014. Barring the unforeseen.
