Princeton tuition was 26K in 2001. It is now 45K. That's 3% growth in tuition, cutting into your estimate. The current endowment growth is already being spent to fund the university to the tune of ~4-6% [1]. So, if you take that source away, tuition would likely have to pick up the slack. Care to rerun your numbers adding this all in?
