Top 10 Student Loan Mistakes to Avoid: Essential Tips

A chalkboard that has "student loan debt" written on it with three stacked books and a degree on top of the books.

It’s no secret: whether you're a college-bound student or a supporting parent, planning how to pay for higher education is critical. Student loan debt is now one of the largest categories of consumer debt in the U.S., and for many borrowers, federal student loans are necessary to access a valuable education.

If you're not careful, student debt can grow rapidly. You’re still responsible for repayment—even in bankruptcy—so it's important to understand how the student loan process works. Avoid these 10 common mistakes to keep your finances on track and your monthly student loan payment manageable.

1. Taking Out the Wrong Type of Loan

When you complete the FAFSA (Free Application for Federal Student Aid), you may not qualify for enough aid to cover your college costs. At that point, you may consider private or consolidation loans. But each type of loan has different terms, interest rates, and eligibility criteria.

  • Federal Subsidized Loans – Based on income and family size, these do not build interest while you’re in school. If you’re eligible, they are usually the safest place to begin.
  • Unsubsidized Federal Student Loans – Interest starts accumulating immediately, regardless of financial need.
  • Direct Loans – This category covers subsidized, unsubsidized, and Parent PLUS loans. Your FAFSA determines eligibility.
  • Private Loans – Issued by banks and other lenders, these rely heavily on your credit score and typically do not offer income driven repayment options.
  • Consolidation Loans – They can streamline multiple payments into one, but in some cases may reduce access to loan forgiveness programs such as Public Service Loan Forgiveness (PSLF).

The loan you choose at the start can shape what you’re able to qualify for later, so it pays to look closely before signing.

2. Choosing Loans With Bad Interest Rates

Both private and federal student loans require repayment of principal and interest. However, federal loans have fixed rates and sometimes better repayment protections.

  • Direct Loans start accruing interest upon disbursement.
  • With federal subsidized loans, the U.S. Department of Education pays your interest while you’re in school and during deferment.
  • Private loans often have variable rates and may charge prepayment penalties. Review all fees before you sign.

To lower your remaining loan balance, review offers carefully and think twice before locking yourself into high-interest terms.

3. Not Understanding the Difference Between Fixed and Variable APRs

Your loan’s APR (Annual Percentage Rate) has a direct impact on what you ultimately repay. Many private lenders present two structures:

  • Fixed APRs, which keep monthly payments predictable.
  • Variable APRs, which can rise over time and make it more difficult to repay the loan consistently.

A rate that looks manageable today can shift later. Consider how future changes could alter your repayment plan before committing.

4. Taking Out More Student Loans Than You Need

It is easy to accept the full amount offered, especially when extra funds feel like a cushion. But borrowing beyond actual education costs increases your monthly payment and stretches out the repayment period. Paying interest while still in school, when possible, can help keep your remaining balance from climbing.

5. Missing Payments

Skipping even one payment can trigger:

  • Late fees
  • Credit score damage
  • Default, which may limit access to income driven repayment IDR plans or loan forgiveness

Federal student loans offer protections like deferment, forbearance, and forgiveness through the PSLF program (public service loan forgiveness) or Teacher Loan Forgiveness. Private lenders, however, may not offer any special repayment plans.

Always budget for your monthly student loan payments and seek help if you're falling behind. Your account and credit history depend on it.

Remember that federal student loans offer a six month grace period after graduation before borrowers have to make a monthly payment. Private lenders have no obligation to provide grace periods, or alternate payment options like debt forgiveness.

6. Choosing the Wrong Repayment Plan

Most borrowers are placed in the standard 10-year schedule by default. That works for some, but others may benefit from an income driven repayment (IDR) approach, especially if earnings are modest compared to the loan balance.

Common options include:

Income Driven Repayment IDR and Your Monthly Payment

An income driven repayment IDR option adjusts your monthly payment based on earnings rather than loan size alone. If your income is limited, this structure can create breathing room without pushing you into delinquency.

Income Based Repayment and Income Contingent Repayment

Income based repayment and income contingent repayment are two long-standing versions of income driven repayment. Each uses a formula tied to income and household size, and each has different rules about interest and repayment timelines. Reviewing the fine print before selecting an idr plan matters.

Public Service Loan Forgiveness and the PSLF Program

The public service loan forgiveness pathway, often called the pslf program, allows qualifying borrowers working in government or nonprofit roles to pursue loan forgiveness after making the required number of payments under an eligible plan.

Why Federal Student Loans Offer More Flexibility

Most of these protections apply only to federal student loans. Private lenders set their own terms and rarely mirror the same repayment safeguards, which is why understanding the difference before choosing a plan is critical.

These programs calculate payments using your income and family size. In many cases, borrowers may qualify for student loan forgiveness after 20 to 25 years of consistent payments. Those working in public service may see the remaining balance forgiven after 10 years through PSLF, provided they meet the requirements.

7. Missing Application Deadlines

Timing matters. The FAFSA usually becomes available October 1. Waiting too long can shrink your access to federal student loans or delay processing.

If you are considering private loans or scholarships, start earlier than you think you need to. Some lenders and government programs close applications well before funds run out.

8. Not Understanding Co-Signer Responsibilities

Many private loans require a co-signer in order to qualify. That person is equally responsible for the debt if the borrower fails to repay it.

By contrast, federal student loans generally do not require co-signers. When possible, rely on federal loans first to reduce risk for both you and anyone helping you.

9. Ignoring Credit Score Impacts

Student loans show up on your credit report, and how you handle them matters:

  • On-time payments strengthen your credit history
  • Late or missed payments weaken it
  • Default can leave lasting damage

Your credit score influences more than future loans. Landlords, insurers, and some employers review it, so consistent payment habits carry weight.

10. Refinancing Without Understanding the Consequences

Refinancing can streamline student loan payments, particularly if you are juggling multiple accounts. Lower rates are appealing, but there are tradeoffs.

  • You could give up federal loan benefits, including forgiveness, deferment, and IDR plans
  • The refinanced loan may not qualify for borrower defense or PSLF

Only refinance if you're confident that private loan terms will save you money long-term and if you're not planning to apply for any federal student aid-linked benefits.

Final Thoughts: Do Your Research

Before taking on student loan debt, explore your options. Use available resources from the Department of Education and your school’s financial aid office to ensure you understand:

  • The availability of different types of aid
  • How to stay on track with payments
  • Which programs may assist with forgiveness or reduction

The Federal government continues to adjust options for borrowers, including updated IDR plans, closer oversight of institutions, and expanded student loan forgiveness efforts. Many of these provisions focus on those working in public service or individuals who meet certain requirements.

Some borrowers will see their loans fully repaid over time through steady payments, while others may pursue relief tied to policy changes. The Supreme Court has already weighed in on broad cancellation efforts proposed by the Biden administration, which is a reminder that rules can shift. Before you rely on any proposal, understand what your current plan bases payments on, confirm that you are properly enrolled, and assess your own long-term ability to repay. Unlike other forms of debt, student loans are rarely tied to traditional collateral, which means the consequences of missteps often follow your income and credit rather than a specific asset.
