<p>iCalculus what do you want to know? EFC is used to deliver federal monies (Staffords, pells, perkins etc) you have applied to private schools so the situation is not reliant solely on your EFC. EFC is “useful” only because it can give people a benchmark for earnings/savings but private colleges determine their own expected family contribution based on the information your parent(s) submitted. Is there a specific question or are you simply interested in comparing yourself to others? That is difficult because everyone’s’ situation is different. Do call Princeton and walk through your package so that you are comfortable before you make a decision as you and your parent will “live” with this for at least 4 years. Princeton is no loans and expects a certain amount of student contribution – the amount is not defined but buried in the aid information. After that they determine some amount of family contribution and the balance is grants. So “your contribution” + “your parent(s) contribution” + grants = COA. Call them next week. On the surface, in general, it’s a good package for you.</p>
