Suppose Marquis plans to get a Direct Unsubsidized Student Loan, borrowing $5,200 at 6.80% interest. The first disbursement will be in September 2013 (and the second in January 2014). He plans to graduate in 4 years; i.e. in May 2017. He will defer the interest while in school and for the 6 month grace period after graduation, and then begin paying back principal and interest over 10 years. While there is a disbursement fee, it is subtracted from the first disbursement rather than added to the loan request amount.
When will the loan finally be paid off?

Suppose Quincy plans to get a Direct Unsubsidized Student Loan, borrowing $5,000 at 6.80% interest. The first disbursement will be in September 2014 (and the second in January 2015). He plans to graduate in 3.5 years; i.e. in December 2017. He will defer the interest while in school and for the 6 month grace period after graduation, and then begin paying back principal and interest over 10 years. While there is a disbursement fee, it is subtracted from the first disbursement rather than added to the loan request amount.
Once the 10 years of payments for both principal and interest begin, what is the amount of the monthly payment?
