I don't even have a retirement target date, in years, based on my age, or whatever. The house won't be paid off for another 10 years, so hopefully I can keep working until at least then. I haven't saved jack shit towards retirement, despite everyone and everything saying I should for the past 20 years, because we've been perpetually in debt due to my wife never keeping a job and being unemployed more years of our marriage than she's been employed. So while saving up for retirement is a good and smart thing, so is paying the electricity bill and making the house payment, so those kinda came first. The only real savings we have is my 401(k), which currently has about one year's salary (of mine) in it. It'll compound a bit in the next 10 years, but will hardly be the nest egg that most people would count on.
Meanwhile, my mom died and my dad has a boatload of money which my sisters and I will split when he passes. I know this because he sends financial statements to us twice a year. So it sucks to think of it this way, but he's 84 now, and the odds are that he'll pass sometime in the next ten years, leaving us enough money to pay off the house and put the kids through college. Except by then the house will be paid off and the kids will (hopefully) be done with college, so that will become our nest egg. If my dad's still around, great, I'll just keep working. I'll have nothing else to do at that point anyway.
So the only variable -- and it's a biggee -- is whether I'll be able to find/keep a job until then. Where I'm at now, I've been there 10 years and they love me, but that's no guarantee that I'll be there another 10.
