Well, you can congratulate me, we're having a second child! One thing that it reminded me is the value of getting free tuition for my kids by working here at a university! I was curious how much it was worth being a severely underpaid academic in terms of my free tuition benefits.
So here you put in the current astronomical annual tuition of your favorite institution and what you think your average tuition inflation and investment return will be. Then put in the years until your children go to school and how much you have already to invest and how much you will contribute each year.
