“People are borrowing twice as much as they were a decade ago because grants and scholarships are not keeping up with the escalating costs of college,” says Mark Kantrowitz, the publisher of FinAid.org and FastWeb.com, free online financial-aid resources. Graduates of the class of 2020 have an average of $29,200 in debt, up from about $17,600 in 2001. With staggering numbers like these, understanding how student loans work has never been more important. If you’re on a tight budget, it may be difficult to steer any additional cash toward your education debt. But you should try to pay it off as early as possible; otherwise it might stick around for a decade or more, which could prevent you from saving enough for retirement. Here are five steps to paying off any lingering loans of your own—and if you have kids, helping them to settle theirs down the road. “People often make the mistake of going with the option that has the smallest monthly payment, which causes them to pay thousands more in interest over the loan’s life span,” says Lauren Asher, the president of the Institute for College Access & Success, a nonprofit that works to make college more affordable. Aim to put 10 percent of your gross (that is, pre-tax) income toward your education debt. Use Loan Simulator from StudentAid.gov to calculate which repayment plan fits your budget. If you’re a recent grad looking for a job, bring this up during salary negotiations. Be willing to take a lower salary and to commit to staying at the job for a specific time period in exchange for a payment toward your schooling. If you’re a veteran employee, raise the subject at your annual review by saying, “I’ve been a loyal employee for [insert time period], and I look forward to continuing to grow and learn here. As part of my compensation, can you put [insert amount] toward my loan?”
