It's payback time for students who graduated from college last spring owing money on federal student loans. Your six-month-long grace period is about to end, and the money you owe--an average of $16,600 for undergraduates 18 to 25, according to Nellie Mae, a major student-loan provider--is looming large. The burden is still heavier when you add on credit card debt, which Nellie Mae says averages $2,000 for the same group of students, and maybe even payments you're making on a new car. What's the best way to balance the load?

Rebecca Carter has a plan. Carter, 31, is a veteran of student loans, having repaid about $7,500 from her first stab at college a decade ago. Two years ago she returned to school to complete her degree in business administration at Eastern Nazarene College, in Quincy, Mass.; she graduated in August with $23,000 in outstanding loans.

Carter is wiser, if not richer, the second time around. Before she begins repayment next March, Carter plans to consolidate loans from three lenders (with interest averaging about 7.5%) into a new loan from a single lender, and to extend the payment term from the standard ten years to 20 years. Carter estimates that loan consolidation will reduce her monthly payments 40%, so that she'll pay between $200 and $250 a month. That will give her breathing room to make payments on her more-expensive car loan at 11%.
