The BU net price calculator has been around a long time, and is generally pretty close to accurate…but if your parents are divorced, own a business, are self employed, or own real estate other than their primary residence, it won’t be accurate.
Also, the info you enter has to be accurate. So if you made one mistake on the net price calculator, it might have given you a big wrong answer.
Also, 10 times means lots of things. Did the NPC say $1000 and you are now paying $10,000 or did it say $5000 and you are now paying $50,000?
What “lots of loans” did this include? Parent Plus loans are parent loans, not student financial aid.
What was your package?
