Most people treat student loans like a formality. You sign what the financial aid office puts in front of you, you figure it out later. I get it. When you’re 17 or 18 and just trying to get to campus, the fine print feels like a problem for future you. But the decisions you make when you first borrow set up the entire structure of your loan situation for years afterward, so it’s worth actually understanding what you’re signing up for before you click accept.
The federal versus private distinction is the most important split in student lending. These are not just two flavors of the same thing. They work differently, they protect you differently, and they fail you differently when things go wrong.
| Feature | Federal Loans | Private Loans |
|---|---|---|
| Interest Rate Type | Fixed, set by Congress | Fixed or variable, set by lender |
| Credit Check Required | No (most loans) | Yes |
| Income-Driven Repayment | Available | Not available |
| Public Service Loan Forgiveness | Eligible | Not eligible |
| Deferment / Forbearance | Standardized options | Varies by lender |
| Origination Fee | 1.057% to 4.228% (2025-26) | Often none |
Federal Loans: The Baseline You Should Max Before Looking Elsewhere
Federal loans come from the U.S. Department of Education, and the rates are set by Congress each year based on the 10-year Treasury note. For the 2025-26 academic year, undergraduate Direct Subsidized and Unsubsidized loans are at 6.53% fixed. Graduate Direct Unsubsidized loans are at 8.08%. Direct PLUS loans, which cover graduate students and parents, come in at 9.08%.
Those rates are not spectacular. But fixed is fixed. You know exactly what you’re getting for the life of the loan, and you’re not gambling on where interest rates go over the next decade.
Subsidized vs. Unsubsidized
The subsidized versus unsubsidized distinction matters a lot more than most people realize when they’re first borrowing. Subsidized loans don’t accrue interest while you’re in school at least half-time, during the six-month grace period after graduation, or during approved deferment periods. Unsubsidized loans start accruing interest immediately. If you borrow $5,500 in unsubsidized loans as a freshman and let the interest capitalize over four years, you’ll owe more than your original balance by the time you hit repayment. I break this down more in this piece on the subsidized vs. unsubsidized difference if you want the full picture.
The annual borrowing limits are also capped. Dependent undergraduates can borrow between $5,500 and $7,500 per year in Direct loans depending on year in school, with lifetime limits of $31,000. That’s probably not enough to cover everything at a private university or an out-of-state school. That’s where private loans enter the conversation.
Why Federal Protections Are Worth Real Money
The part that doesn’t show up in an interest rate comparison is the safety net built into federal loans. Income-driven repayment plans like SAVE, PAYE, and IBR cap your monthly payment as a percentage of your discretionary income. If you graduate into a low-paying job or lose your job entirely, your payment can drop to zero without defaulting. That kind of flexibility is genuinely valuable and you don’t realize how valuable until you actually need it.
Public Service Loan Forgiveness is also federal-only. If you go into government work, nonprofit work, or public education and make 120 qualifying payments under an income-driven plan, your remaining balance is forgiven tax-free. For anyone considering those paths, understanding income-driven repayment plans is not optional reading.
Deferment and forbearance options are also standardized on the federal side. You know what you’re getting. Private lenders can offer hardship programs, but there’s no guarantee and the terms vary widely by lender.
Private Loans: Sometimes Necessary, Never the First Choice
Private loans come from banks, credit unions, and online lenders. Sallie Mae, Earnest, College Ave, Discover, and SoFi are among the bigger names. The rates, terms, and underwriting criteria are all set by the lender, which means there’s significantly more variation.
Current private loan rates as of mid-2025 run roughly from about 4.5% to 16% depending on your credit profile. The lower end is for borrowers with strong credit and a creditworthy cosigner, usually a parent. The upper end is where you end up if your credit history is thin or your cosigner’s profile is weaker. Most college students don’t have the credit score to get a good rate on their own.
When Private Loans Actually Make Sense
If you’ve maxed your federal eligibility, exhausted scholarship options, and still have a gap to fill, private loans can legitimately be the right call. They’re also sometimes competitive on rate for graduate students or working adults with strong credit who don’t need the income-driven repayment flexibility. Earnest, for example, currently advertises fixed rates starting around 4.99% for well-qualified borrowers, which can undercut federal grad rates if your credit profile is strong enough.
Variable rate private loans can look attractive early on, especially when short-term rates are low. But variable means the rate can move up, and a loan that starts at 5.5% variable could look very different in year four of repayment. I’d be skeptical of that trade-off unless you have a clear plan to pay the loan off quickly and you’ve actually modeled what happens if rates climb another two points.
One thing private loans get right: many of them don’t charge origination fees. Federal loans do. A 1.057% origination fee on a $10,000 loan means you receive $9,894 but owe $10,000 from day one. It’s not enormous, but it’s a real cost that doesn’t show up in the interest rate headline.
How to Actually Choose
Exhaust federal loans first. That’s not a controversial opinion, it’s just the rational move when you’re comparing a product with income protections and forgiveness eligibility against one with neither. The only time I’d even consider leading with private loans is if federal rates are dramatically higher than what a creditworthy cosigner could get you privately, and you’re confident you won’t need income-driven repayment.
After you’ve accepted your federal aid, look at the actual gap. If you need $8,000 more than your federal loans cover and your parents have strong credit, shopping private lenders makes sense. Get quotes from at least three lenders because rates vary more than you’d expect across similar products. College Ave, Earnest, and Sallie Mae are worth comparing side by side. Check both fixed and variable options, and read the fine print on what happens if you want to defer payments or if you lose your job.
If you’re already in repayment and you have strong credit plus stable income, refinancing federal loans into a private loan can lower your rate but it permanently strips your federal protections. That’s a meaningful trade-off. I covered the full decision framework in this piece on whether refinancing is worth it, because it deserves more than a paragraph.
The other thing I’d say: don’t assume borrowing is the only lever you have. My first internship paycheck had $340 withheld in taxes I hadn’t accounted for. I spent an hour that night actually reading about withholding and gross versus net pay. That same kind of careful math applies to student loans. Understand what you’re actually borrowing, what it’ll cost in total interest, and what the monthly payment looks like at different income levels before you sign anything.

Both types of loans are tools. Federal loans are the Swiss Army knife with a built-in safety net. Private loans are sometimes sharper but significantly less forgiving if things don’t go according to plan.
Frequently Asked Questions
Q: Should I always take federal loans before private loans? Yes, in almost every situation. Federal loans come with income-driven repayment options, potential forgiveness eligibility, and standardized deferment protections that private loans simply don’t offer, and those protections have real financial value even if you never end up needing them.
Q: Can I get a private student loan without a cosigner? Some lenders like Earnest and Ascent offer no-cosigner options, but you’ll need a solid credit history and proof of income, which most undergrads don’t have. Without a cosigner your rate will likely be significantly higher than the advertised starting rates.
Q: Do private student loans qualify for Public Service Loan Forgiveness? No. PSLF applies only to federal Direct loans. If you refinance federal loans into a private loan, you permanently lose PSLF eligibility, so anyone on a public service track should think carefully before refinancing.
Q: What’s the difference between a fixed and variable rate private loan? A fixed rate stays the same for the life of the loan. A variable rate is tied to a benchmark like SOFR and can change monthly or quarterly. Variable rates often start lower but carry real risk if rates rise during your repayment period.
Q: How do I know how much I can borrow in federal loans? Your school’s financial aid office determines your cost of attendance and your Expected Family Contribution, and the gap between them sets your federal aid eligibility. Dependent undergrads are capped at $31,000 in total federal borrowing, regardless of what their school costs.
