I was filling out the International Student Financial Aid Application and there is a questions that asks for the amount of money paid on debt. What does that mean exactly?

Thanks.

Do your parents have any debt (did they borrow money from a bank or a person)?

If so, how much did they repay?

But there is another question that asks about loan payments earlier. Do you think this might be the amount of interest they paid on the debt? @Madison85
