This is the default repayment plan for Federal Stafford, Grad PLUS, and Parent PLUS loans. With this plan you'll pay a fixed amount each month for 10 years, with minimum monthly payments of at least $50. The federal government offers a borrower benefit of .25% interest rate reduction for payments made through automatic debit to encourage borrowers to repay these loans in a responsible way. Because this plan has the shortest repayment period, it's the quickest way to pay back your debt.
