Student Loans, Explained Simply

Before you sign anything, understand what a student loan is: a promise to repay borrowed money, plus interest, years before you know what your first paycheck will look like. Not every loan works the same way, either. Federal loans come with protections written into law; private loans come with whatever a bank decides to offer. The order you borrow in can matter almost as much as the amount.

Why does borrowing order matter so much?

Federal Direct Loans are issued by the U.S. Department of Education under terms fixed by federal law. A private loan is issued by a bank, credit union, or online lender under terms that lender sets — including whether it requires a cosigner, whether the rate is fixed or variable, and what happens if you lose your job. The CFPB's overview of federal versus private loans puts it plainly: private loans "don't offer the same protections for consumers."

How do federal and private loans compare side by side?

Lined up next to each other, the two loan types barely resemble each other outside of the word "loan":

What's the difference between subsidized and unsubsidized loans?

Subsidized loans are only available to undergraduates who demonstrate financial need on the FAFSA, and only up to a set dollar cap each year (covered below). Unsubsidized loans are open to more borrowers, including graduate and professional students, but the trade-off is that interest never pauses just because you're in class.

What happens to interest while you're still enrolled?

How much can you actually borrow?

Annual limits for Direct Subsidized and Unsubsidized Loans, per the Federal Student Aid Handbook:

• Dependent undergraduates: $5,500 (first year), $6,500 (second year), $7,500 (third year and beyond) — no more than $3,500 / $4,500 / $5,500 of each may be subsidized.
• Independent undergraduates (and dependents whose parent can't get a PLUS loan): $9,500, $10,500, and $12,500 for the same three years, with the same subsidized caps.
• Graduate and professional students: $20,500 per year, unsubsidized only.

Aggregate (lifetime) limits for the same loan types:

• Dependent undergraduates: $31,000 total, no more than $23,000 subsidized.
• Independent undergraduates: $57,500 total, no more than $23,000 subsidized.
• Graduate and professional students: $138,500 total (including undergraduate borrowing), no more than $65,500 subsidized.

Direct PLUS Loans — for graduate students (Grad PLUS) or parents of dependent undergraduates (Parent PLUS) — have historically had no fixed annual cap, borrowable up to the school's full cost of attendance minus other aid, per CFPB's PLUS loan explainer.

What does a real balance turn into as a monthly payment?

Here's the math behind that number. A dependent undergraduate who borrowed the maximum federal amount across four years — $5,500 + $6,500 + $7,500 + $7,500 — has borrowed $27,000. At 6.52% (the confirmed rate for Direct Loans first disbursed between July 1, 2026 and June 30, 2027) over a standard 120-month term, the fixed monthly payment works out to approximately $307.

1. Start with the balance and rate

   $27,000 borrowed at a fixed 6.52% annual rate, the confirmed rate for undergraduate Direct Loans disbursed in the 2026-27 cycle.

2. Apply the standard 10-year term

   Spread over 120 equal monthly payments, that balance and rate produce a payment of about $307 a month.

3. Add up the interest

   Over the full 10 years, total payments come to roughly $36,840 — meaning about $9,840 of that is interest, not principal.

4. Compare against a larger balance

   The Department of Education's own example shows a $30,000 balance costing $341 a month on the old fixed 10-year plan, versus about $262 a month on the new tiered standard plan, which stretches repayment to 15 years for that balance size.

Frequently asked questions

Do federal loans always cost less than private loans?

Not automatically, but they usually carry more built-in protection at the same time. A borrower with excellent credit might qualify for a lower private rate than the federal fixed rate, but that private loan still won't come with income-driven repayment, federal forgiveness eligibility, or automatic death and disability discharge.

Can a dependent student get independent-level loan limits?

Sometimes. If a dependent student's parent is denied a PLUS loan or can't apply for other documented reasons, the student can become eligible for the higher unsubsidized limits that independent students receive — though this doesn't change the student's dependency status for other financial aid purposes.

Does interest ever stop once repayment starts?

No — once repayment begins, interest keeps accruing on any outstanding balance under every standard repayment plan. Some newer income-driven options address runaway interest differently; that's covered in our repayment options guide.

Is a PLUS loan the same as cosigning a private loan?

No, and the difference matters. A Parent PLUS loan is a separate federal loan in the parent's own name; a cosigned private loan is the student's loan with the parent equally liable. See cosigning student loans for the full comparison.

Common mistakes to avoid

• ✕Borrowing private loans before maxing out federal aid, losing access to income-driven repayment and forgiveness eligibility for no rate benefit.
• ✕Assuming subsidized and unsubsidized loans have different interest rates — the rate is set by loan type and year, not by subsidy status.
• ✕Ignoring accruing interest during school, then being surprised when it capitalizes into a larger starting balance at repayment.
• ✕Treating the aggregate loan limit as a target to reach rather than a ceiling — borrowing the minimum needed each year leaves room later.
• ✕Signing a private loan's cosigner section without reading the release terms, discussed in our cosigning guide.
• ✕Assuming a lender's marketing about 'low rates' accounts for the loss of federal protections like deferment and disability discharge.
