Good point!
@Winsto7 – Here is the link for the actual NPC for W&M: Welcome | Net Price Calculator (collegeboard.org)
It will be the most accurate assessment of what your aid should be. But, as always, it may not be accurate for families that own their small business.
Here is the other calculator they offer: Welcome - William & Mary - MyinTuition (myintuitionapp.org) . This is usually much less accurate.
I suggest you run both and see what they say and then take the results of both to the meeting with the financial aid officer as a comparison to be used vis a vis their actual aid offer. Make sure they know you have 3 siblings who will also be in college. It may not make a difference anymore (new FAFSA rules) but it never hurts to let them know.
