How long of a term did you choose and what was your assumed loan balance? At balances over $60,000, you can choose an extended term up to 30 years. There are also a lot of different repayment options. A standard repayment plan has a minimum payment of $50 a month.
Anyway, it's a very bad idea to go into forbearance unless absolutely necessary. It is the only time in your life you will be able to take advantage of the $2500 in interest payment deductions so you should definitely pay at least that much a year. Also, the interest will be accruing so quickly that it is a good idea to start paying at least the interest.
