Student loan debt in the US exceeds $1.7 trillion — most of it carried by people who didn't fully understand what they were signing when they borrowed. The choices you make before taking on student debt — federal vs. private, how much to borrow, which repayment plan to choose — have enormous long-term financial consequences. This guide gives you the framework to borrow wisely.

Step 1: Federal Aid First — Always

Before considering any loans, complete the FAFSA (Free Application for Federal Student Aid). The FAFSA determines your eligibility for federal grants (Pell Grants for lower-income students), work-study programs, and federal loans. Federal loans should always be your first choice because they come with protections private loans lack: income-driven repayment plans, Public Service Loan Forgiveness, deferment and forbearance options, and fixed interest rates set by Congress rather than credit markets.

The FAFSA window opens October 1 each year for the following academic year. Submit it as early as possible — some grant money is first-come, first-served. Even families who think they make too much to qualify should file: the calculation includes factors beyond income, and many middle-class families qualify for subsidized loans.

Step 2: Types of Federal Student Loans

Everything You Need To Know About Student Loans

Federal Direct Subsidized Loans are the best available: the government pays your interest while you're enrolled at least half-time, during the 6-month grace period after graduation, and during deferment. This prevents interest from compounding while you're in school. Only undergraduates with demonstrated financial need qualify, and there are annual and aggregate limits ($23,000 aggregate for dependent undergrads).

Federal Direct Unsubsidized Loans are available regardless of financial need to undergraduates, graduate students, and professional students. Interest accrues immediately — unpaid interest capitalizes (is added to the principal) when you enter repayment, increasing your total balance. Annual limits are $5,500–$20,500 depending on year in school and dependency status. PLUS Loans (for parents or graduate students) have higher limits but also higher rates and no subsidized option.

Step 3: How Much to Borrow — The 10% Rule

A practical rule: total student loan debt at graduation should not exceed your expected first-year salary. If you're projected to earn $45,000 in your first job, borrowing $45,000 total is manageable; borrowing $90,000 is likely to cause serious financial hardship. Your monthly loan payment should ideally stay below 10% of your gross monthly income — above 15%, the debt significantly constrains your life choices.

Use the Department of Education's loan simulator (studentaid.gov) to project monthly payments under different repayment plans before borrowing. Borrowing the maximum offered isn't the same as needing the maximum — live frugally in school to borrow less.

Step 4: When Private Loans Make Sense

Your Guide to Student Loan Repayment Plans

Private student loans from banks, credit unions, and online lenders (Sallie Mae, Earnest, College Ave, SoFi) are appropriate only after exhausting all federal loans and grants, and only when you genuinely cannot cover remaining costs through savings, work, or family contributions. Private loans require a credit check and typically a co-signer for students without established credit. Variable-rate private loans can start lower than federal rates but carry interest rate risk over the repayment period.

Private loans lack income-driven repayment options — if you lose your job, you still owe the full payment. They're also ineligible for federal forgiveness programs including Public Service Loan Forgiveness. The relative inflexibility of private loans means even if the interest rate is slightly lower, the risk-adjusted cost is often higher than federal alternatives. See our Best Student Loan Refinance guide for refinancing options after graduation.

Step 5: Understanding Repayment Plans

Federal loans offer multiple repayment options that private loans don't. Standard Repayment (10 years, fixed payments) minimizes total interest but has higher monthly payments. Graduated Repayment starts with lower payments that increase every 2 years. Extended Repayment stretches to 25 years for lower payments but significantly more total interest. Income-Driven Repayment plans (SAVE, PAYE, IBR) cap payments at 5–20% of discretionary income and forgive remaining balances after 10–25 years, depending on the plan — the recently implemented SAVE plan is the most generous for low and middle-income borrowers.

Public Service Loan Forgiveness (PSLF) forgives remaining federal loan balances after 120 qualifying payments (10 years) while working full-time for a qualifying public or nonprofit employer — government, teachers, nurses, social workers. If you're planning a career in public service, this program is worth optimizing around from day one.

Step 6: Interest Rates and Loan Fees

Federal student loan interest rates are set annually by Congress based on the 10-year Treasury yield. For 2025-2026, undergraduate Direct Loans are set at 6.53%, graduate Unsubsidized Loans at 8.08%, and PLUS Loans at 9.08%. Federal loans have no origination fees except PLUS Loans (approximately 4.2% fee).

Private student loan rates range from approximately 4% to 16% depending on credit, with variable rates typically starting lower. When comparing rates, look at APR, not just the stated interest rate, and account for any loan origination fees. Federal loan rates are currently competitive with or lower than private rates for most borrowers; for borrowers with excellent credit, private rates can occasionally be marginally lower, but the lack of federal protections is a real cost to weigh.

Step 7: Before You Sign — Critical Checks

What Everyone's Getting Wrong About Student Loans

Before signing any student loan: verify the total amount you're taking on vs. the financial aid letter's individual offer; understand whether the rate is fixed or variable; confirm what happens to your rate and payments if you take a leave of absence or drop below half-time enrollment; know the grace period after graduation; and understand your deferment and forbearance options. Read the Master Promissory Note (MPN) — it's your legal obligation. Request a "plain English" summary from your school's financial aid office if any terms are unclear.
