I dream of the day. Right now I'm a good 35-40 years shy and a whole lotta money short of it.

I like looking at calculators to figure out what I think I'll need. Here's one you can plug and play with. Give you an idea of what you'll be able to draw while it's still being invested and what not.

Also no debt at retirement would be helpful
