Your student loan servicer is the company that handles your bills, questions, and paperwork. It might not be the original lender, and it can change. That feels annoying, but it matters. If you know who your servicer is and what your statements mean while you’re still in school, you can avoid ugly surprises later.

When you’re enrolled at least half-time, many federal loans go into in-school deferment. That means you don’t have to make payments. It does not always mean interest stops growing. Direct Subsidized loans usually get an interest subsidy during deferment. Direct Unsubsidized loans do not. Interest piles up every day, and your balance can grow even if you never borrowed another dollar. Private loans often accrue interest too. So when a statement shows a balance higher than what you borrowed, that’s not a scam. It’s interest.

The first thing to do is log in to your servicer’s website and find your statements. Look for three numbers: current principal, accrued interest, and any amount due. Current principal is what you actually borrowed and still owe. Accrued interest is the interest that has built up but hasn’t been added to principal yet. Amount due is what they want now. If you’re in deferment, amount due may be zero. Don’t stop there. Check whether interest is accruing and whether it will capitalize. Capitalization means unpaid interest gets added to principal, and then you pay interest on that interest. It’s the quiet way student debt grows. If you can pay even a small amount toward accrued interest while in school, you can shrink that future damage. You are not required to, but it’s one of the smartest moves if you have spare cash.

Next, know the difference between federal and private loans. Federal loans come with protections like income-driven repayment, deferment, forbearance, and forgiveness programs. Private loans usually have fewer safety nets. Your servicer’s name doesn’t tell you which type you have. A company can service both. Go to studentaid.gov to see all your federal loans and their servicers. For private loans, check your credit report or your original loan documents. If you’re not sure, call your servicer and ask. Write down the date, the name of the person you spoke with, and what they told you. Save screenshots. That paper trail saves headaches.

Statements can be confusing because servicers use different formats. One might call it “unpaid interest.“ Another might say “interest accrued.“ Another might show a “payoff amount” that looks huge. Focus on the basics. What is the interest rate? When does repayment start? Is the loan in deferment or forbearance? Deferment is usually better because of interest subsidies on subsidized loans. Forbearance almost always lets interest grow. If a servicer suggests forbearance, ask if deferment or another option fits your situation. Also ask about auto-pay discounts. Many servicers knock a quarter percent off your rate if you enroll in automatic payments. That’s small, but over years it adds up.

If your servicer changes, don’t panic. You should get a notice by mail or email. The old servicer may stop accepting payments after a transfer date. The new servicer should honor your loan terms. Update your login, billing address, and auto-pay. Confirm the transfer in writing. If you accidentally pay the old servicer, call both companies right away. Keep records until the payment lands in the right place.

Watch out for scams. A real servicer will never ask for gift cards, wire transfers, or a fee to apply for federal repayment plans. If someone promises to make your student debt disappear for an upfront fee, walk away. You can handle most things yourself for free. If you feel lost, call your servicer and ask for a plain-English explanation. You pay for that service through your loan, so use it.

The easiest habit is a monthly ten-minute check. Log in, read the statement, note the balance and interest, and update your calendar for anything important. Do that while you’re in school, and repayment won’t feel like a blindside. You don’t need to be perfect. You just need to know who holds your loans, what they’re charging, and what choices you have. That’s how you stay in control.
